WARRANTY –SAFETY WARNINGS 3

4. AVOID contact with the exterior of the coil/heat

exchanger assembly, mufflers, and exhaust port or

stack to prevent burns.

5. DO NOT store fuel or other flammable materials

near the burner or any other open flame.

6. Diesel fired or gasoline power units are designed

for outdoor use and installation only.

7. Burner on/off switch must be placed in the OFF

position when the pressure washer is not being used.

Do not depend on engine run switch to turn the burner

off –this may cause a safety hazard.

8. Warning: Burner (water heater) should start only

when water is sprayed. Stop the system/engine

immediately if burner continues to fire when trigger

gun is off.

VENTILATION PRECAUTIONS:

1. Use diesel heated and/or engine powered

products only in well ventilated areas. Exhaust gases

contain carbon monoxide, an odorless, deadly poison.

2. Observe all State, Local, and National codes

providing for indoor use or installation of this unit.

3. Provide adequate ventilation to prevent excess

carbon monoxide levels, engine overheating and

inefficient burner combustion (min. 2’ air space). Do

not restrict normal engine airflow.

4. For engine driven units mounted in a van or box

truck type vehicles, provide an external engine

exhaust line that is larger in diameter than the factory

exhaust pipe and vent the exhaust to the outside of

the vehicle, but not below the vehicle’s interior floor

height. Also, insure adequate fresh air circulation

within the van for engine cooling purposes to prevent

heat build-up and for engine fresh air intake.

Clearance of at least 12” is recommended on all sides

of the unit. Provide a burner exhaust vent, at least 8”

diameter, to the outside through the van roof, or

though the side panel that is at least 10” in diameter,

and position this vent to avoid water, dirt and debris

collection. No flammable liquids, aerosols, or

flammable materials should be stored within 24” of the

unit and should not be stored under the unit. During

refueling, ALL ignition sources and switches should be

OFF and there should be a person with the proper fire

extinguisher and training within the vicinity of the unit

in case of fire. Unit should not be left running

unattended or out of sight.

SPRAY INJECTION PRECAUTION:

1. Fluid from high-pressure spray or leaks can

penetrate the skin and cause serious injury. If any

fluid appears to penetrate the skin, get emergency

medical help at once. DO NOT treat as a simple cut.

Tell the physician exactly what fluid was injected. For

treatment instructions, have the physician call your

local poison center. Without proper treatment,

complications can develop.

2. WARNING –Risk of injection or severe injury to

persons –Keep clear of nozzle. DO NOT direct

discharge stream at people. This machine is to be

used by trained operators. Keep operating area clear

of all people. Use only 48” long wands on machines

producing over 3000 PSI. Also, only use straight

wands or wands with a bend of 10° or less.

CAUTION: Hot discharge fluid –DO NOT touch or

direct discharge stream at people. Gun kicks back –

Hold with both hands. Stay alert –Watch what you

are doing.

3. Always wear protective eye goggles when

operating the equipment. Additional protective items

such as a rubber suit, gloves, and respirators are

advisable, particularly when using cleaning detergents

SAFETY WARNINGS 4

BEFORE START UP: Read all instructions

1. CHECK PUMP OIL: Check pump oil by locating

the oil view window. Depending on your pump model,

fill to the red dot or to center of the site glass window.

2. CHECK FLUID LEVELS: Check engine oil and

coolant levels if unit is so equipped. (See the

maintenance schedule on back page).

3. CONNECT HOSE AND GUN ASSEMBLY.

CONNECT THE WATER SUPPLY & TURN WATER

ON: Maintain an adequate supply of water using a ⅝”

to ¾” I.D. hose with a pressure between 25 and 60psi.

4. Burner power switches should be “off”before

starting. If tank fed, be sure there is water in the tank

and the valve is switched for supply tank feed. Do not

run dry.

5. BATTERY INFORMATION (when equipped):

Batteries are available through your dealer or local

auto parts store. Depending on the type of battery you

purchase, you may have to fill it with electrolyte.

WEAR EYE PROTECTION!

We recommend deep cycle batteries for machines

equipped with 12vdc powered burners. If the opening

on your battery box measures 9”x6”, select U1L/GTH

235 CCA. If the opening measures 8”x12”, use group

24 battery. Always connect the positive battery cable

before the negative and coat the battery terminals with

corrosion inhibitor to prevent corrosion. Do not

reverse polarity.

6. If wheel kit, accessories, or discharge hose are not

installed, see your local dealer for instructions &

installation.

OPERATION:

1. STARTING:

Electric Powered Units: Connect power supply and

ensure that all wiring connections and voltages are of

sufficient rating to comply with equipment requirement.

Turn pump power switch on.

Gasoline Engine Units: Turn engine power switch to

the on position, choke if necessary and turn key to

start position only until engine starts. On units with a

recoil starter, pull cord rapidly, until the engine starts.

2. PURGE AIR FROM SYSTEM:

Squeeze the trigger on the spray gun until a constant

stream of water comes out. (Purging works best with

nozzle removed from wand and/or dual wand in the

low-pressure mode.)

3. SELECT DESIRED NOZZLE

Connect nozzle securely to spray wand. If equipped,

close pressure-adjusting knob on dual wand. Hold

gun firmly, squeeze trigger for high-pressure spray.

CAUTION –Gun kicks back –hold with both hands.

WARNING –risk of explosion –DO NOT spray

flammable liquids.

4. START HEATER / BURNER:

a. Diesel heated: To create hot water on high

pressure washers equipped with heat

exchangers, release the trigger on the gun then

turn the burner to the “on” position.

b. Turn the thermostat to the desired temperature.

Squeeze the trigger on the spray gun and the

burner/heater will begin heating the water. It will

stop heating whenever the water spray is off or if

the temperature setting is exceeded. Heat rise

will vary depending on the inlet water

temperature and environmental conditions.

5. STEAM: (If Equipped) Insert steam nozzle and

turn thermostat to 250° steam setting. The steam

nozzle is sized for approximately 25% less water

volume than the hot water mode.

6. BYPASS MODE: (if equipped): System will go into

bypass mode when machine is left running and trigger

gun is closed. Bypass mode is when the inlet water

coming into the pump re-circulates through the

unloader across the pump head. If left in bypass too

long –more than five minutes –friction created by the

movement of the water will begin to heat the water at

a rapid rate. If equipped with a THERMAL DUMP

VALVE, water exceeding 145°F will cause the valve to

open allowing the cool water in to the pump. The

valve will reset itself when water temperature comes

down to a safe level. If equipped with a bulk water

tank, water can be bypassed back through the tank

allowing for a larger volume of water to be re-

circulated through the pump head thus reducing heat

on the pump seals. Warning: Do not leave in bypass

for longer than five minutes to prevent pump from

overheating. Shut off unit when not spraying water.

7. If unit is equipped with a downstream chemical

injector, connect the chemical injection assembly into

the high-pressure discharge hose quick connects.

Place the chemical pickup into chemical solution and

turn brass collar to adjust concentration. The

chemical will inject only when you drop the outlet

pressure by opening the valve on the dual wand or

changing to a low-pressure nozzle. Soap the surface

from the bottom up. Rinse and close chemical valve

when not in use.

SPECIFICATIONS

WASHING TECHNIQUES

When washing, always start from the bottom up, and

do the final rinse from the top down. This will keep the

water from streaking the surfaces that are being

cleaned. When applying chemicals, it is also best to

start from the bottom and work up.

In areas where there is no grease or oil present, and

the dirt is loose, cold water may be sufficient. When it

comes to grease, oil, and hard to clean dirt; hot water

and/or chemicals can make the job easier, and speed

up the cleaning process. For applications that require

even more heat and where water use/runoff must be

minimized, switch to the steam mode (if equipped) and

adjust the thermostat for up to 250° steam.

For general washing use a broad pattern spray nozzle

such as the 40-degree nozzle. Backing away from the

surface and using the broad spray nozzle works best

to perform rinsing and delicate surface washing. In

areas where the cleaning is more difficult and in

smaller areas such as cracks and holes, use the

narrow spray nozzles, 15 degree.

Chemicals can be applied in a couple of different

ways. One way is with a hand spray pump. The other

is with the chemical system on the equipment; either

downstream or high pressure depending on the

system you have. When using the high-pressure

chemical system, do not use any caustic chemical as

this may cause damage to the pump. For very harsh

chemicals, it is best to use a hand sprayer. First wet

the surface and wash off heavy debris. Test the

surface to be sure the chemical won’t harm it. Then

apply the chemical and let it work in for couple of

minutes before rinsing. Do not allow chemicals to dry

on the surface.

When rising off the chemicals always start from the

top down. When you are finished using the chemical,

be sure to rinse out the chemical line and valve with

fresh water to prevent clogging.

SHUT DOWN

1. Turn burner switch to the ‘off’position.

2. Rinse & close chemical valve. Turn off chemical

solenoid switch, if equipped.

3. Squeeze the trigger on the spray gun until the

water becomes cool.

4. Turn motor/engine switch off with the appropriate

controls. Turn off diesel engine units by pulling the

throttle kill lever, if not equipped with key shut-off.

5. Turn off water supply.

6. Squeeze trigger to release any trapped pressure in

discharge hose.

7. Turn the main power supply off when not in use for

any extended amount of time.

8. Turn gas valve off when not in use for an extended

period for natural gas/propane heated machines.

9. Disconnect & store hoses.

10. Antifreeze / Winterize equipment:

In the event that the equipment is not to be used for

an extended period, store in heated space or

antifreeze the unit. Run the machine until the float

tank is near empty, fill with a 50% mix of water and

antifreeze and run until antifreeze appears at the high-

pressure outlet. If unit is equipped with a blowout

valve, it may be blown out with compressed air in

addition to using antifreeze solution.

On direct feed units (no float tank), use a 5’ garden

hose to draw the antifreeze mix from a bucket or blow

out the unit with compressed air until only air and no

water comes out of the discharge.

APPEARANCE:

To maintain appearance of the pressure washer, use

stainless steel cleaner on the stainless steel panels.

Warning: Cool down burner before shutting off.

OPERATING INSTRUCTIONS 6

POWER SYSTEMS:

ELECTRIC MOTORS: All single

phase electric motors contain a

manual or automatic thermal

overload, which will shut down the

motor if it overheats. If the overload

or starter shuts down the motor, have an electrician or

an authorized Hot2Go dealer check for electrical

problems. Voltage reading under load should be +/-

10% of name plate voltage on motor. Wait for motor

to cool before re-setting. Depressing the red overload

button located on either the motor or the starter can

reset the motor. Use thumb pressure –do not force.

If equipped with an automatic thermal overload, it will

reset itself after the motor has cooled.

Never spray water on the unit, or damage to the

electric motor(s) may occur.

Consult the manufacturer if running an electric

machine from a generator. Three times total

system wattage is required.

A fused disconnect switch of sufficient ampere rating

should be installed by an electrician to provide power

to the machine. Note: Some dual rated 208-230 VAC

washers include a control circuit power selector

switch, located on the back of the control box. Switch

it to the appropriate position to match your source

voltage. Switches are set by manufacturer to match

recorded test sheet voltage. Refer to the chart above

for electrical requirements. If your unit is equipped

with a ground fault interrupter, it will have to be reset

whenever it is plugged in, or if a ground fault

interruption occurs. Test regularly for proper

operation.

GASOLINE ENGINE: With proper care and

maintenance, your gasoline engine will give years of

trouble free service. Please follow the Service and

Maintenance Guide and the enclosed engine sheet or

contact your local authorized engine

dealer for maintenance and repairs.

Use clean, fresh, unleaded gasoline

with an octane rating of 87 or higher

in the engine fuel tank. Up to 15%

MTBE (methyl tertiary butyl ether) or

10% ethanol is acceptable. Do not

use unapproved gasoline such as E15, E20 or E85

ethanol blends. Any failures from use of these fuels

will not be warranted. Consult engine manual for

proper oil type and capacity. The engine

manufacturer recommends a break-in period at which

time the engine oil and filter should be replaced.

Thereafter, change oil and filter as required by engine

manufacturer. Refer to engine manual for preventative

maintenance schedules and procedures. Do not rely

on the low oil shutdown (if equipped) as a reminder to

add oil. The engine manufacturer will typically not

warranty engine damage from lack of oil even if the

low oil system failed.

On machines with a 12V burner, the throttle is preset

by manufacturer. Some engines include backfire

prevention solenoids.

POWER TRANSMISSION:

WARNING: Shut off power supply before servicing.

BELT DRIVE: Check belt condition, alignment and

tension periodically. Replace belts when they show

signs of wear or cracking. Tighten belts by loosening

the mounting bolts on the pump to permit them to

slide. Turn the horizontal rail adjusting bolts to tighten

belts until they deflect ¼" to ½” with finger pressure.

DIRECT DRIVE: Pump is bolted directly to the

motor/engine. If pump needs to be removed, do not

force off by prying or damage may occur. When

reassembling, coat the entire motor shaft with heavy

grease or a generous amount of anti-seize. Use

“thread locker” or “lock tight” on mounting bolts and

tighten set screw on key shaft.

PUMPING SYSTEM:

PUMP: The pump is a positive

displacement, oil bath crankcase,

and triplex plunger type. It contains

3 plungers, which move forward and

backward in a cylinder to propel

water past 3 inlet valves and 3 discharge valves into a

high-pressure manifold. The crank case oil window

should be checked for oil level and clarity and the

pump for oil or water leaks before each use. The sight

window is located at the rear (opposite the head) of

the pump and should be filled to the red dot with

specified pump oil, available at your Hot2Go dealer

(refer to maintenance schedule on back page). If the

oil becomes milky in color, moisture is entering the

crankcase. Change the oil and contact your

authorized Hot2Go dealer if the problem persists.

Keeping filters clean and checking for air in pump feed

lines can prevent cavitation and increase pump life.

Do not run pump in the bypass mode (pump running

with the trigger gun off), for a period of more than 5

minutes or the pump will begin to overheat (maximum

water temperature is 145°F). Do not run pump dry.

Protect from freezing. Do not run a frozen pump until

it is completely thawed.

SYSTEM INFORMATION 7

UNLOADER AND PRESSURE RELIEF VALVE: The

unloader valve is preset by manufacturer to

govern the proper output pressure of your

machine. It will release the pressure of the

pump back into the inlet if the trigger on the

spray gun is released. NEVER increase the

set pressure on the unloader to exceed the

specifications for your machine.

All hot water machines are equipped

with a SAFETY PRESSURE RELIEF

VALVE. In the unlikely event that your

unloader fails, or if the burner

overheats and builds excessive pressure, the pressure

relief valve will vent the pressure into the atmosphere.

If this occurs, turn off the machine and have it checked

by an authorized dealer. The pressure relief valve will

automatically reset itself.

BURST DISC TECHNOLOGY: This additional safety

feature functions to protect the coil & heating system

from the spikes of high pressure. If this component

ruptures, take the machine in to an authorized Hot2Go

dealer. Do not plug off and continue to run.

CHEMICAL INJECTION SYSTEM: An optional

DOWNSTREAM INJECTOR is available if harsh

chemicals need to be applied. The downstream

injector will apply chemicals only at low pressure, by

installing black soap nozzle or opening spray wand

valve if equipped. If equipped

standard with downstream injection,

adjust concentration level by turning

brass collar on the injector, or the

knob on pump or control panel. Read

and follow all safety instructions on

the detergent label.

WATER SUPPLY: An adequate water supply to the

pump must be maintained at all times. If the inlet flow

is too low or if there is air in the water supply, the

pump will run rough, pulsate and lose pressure.

Maximum inlet water temperature is 145°F. Do not

restrict inlet water supply. If the pump is run dry, it can

quickly overheat. The water is filtered by a garden

hose adapter screen. Clean and replace as required

or install a large capacity strainer to insure a clean

supply of water.

Direct water feed: Maintain an inlet water pressure

between 25 PSI and 60 PSI using a ⅝” to ¾” I.D.

hose. Install a back flow preventer on your supply

hose if State or Local ordinances require it. Install a

water regulator if your water pressure exceeds 60 PSI.

Bulk tank water supply: Large capacity water supply

tanks can be used with most belt driven units if water

is not readily available at the washing site. Belt

driven, low speed pumps (less than 1750 RPM) can

draw from a tank if you ensure that the vacuum does

not exceed negative 3psi. An 80 mesh, 200 micron

strainer and a ¾” I.D. or larger suction hose must be

used to maintain a clean and adequate water supply.

Be sure that the water supply is free from air or

damage to the pump may result. Periodically you

should clean out the strainer and water supply tank to

remove debris that may accumulate on the bottom. If

a water supply tank and a float tank are both utilized, a

special three way valve can be used to switch

between tanks.

USING DE-IONIZED OR SOFTENED WATER IN

YOUR PRESSURE WASHER: Do not use de-ionized

water through the coil on a hot water machine or coil

corrosion will result. Water softeners, however, will

reduce coil scale deposits and should be installed if

your water is especially hard.

HEATING SYSTEM:

HEAT EXCHANGER SYSTEM:

The heat exchanger on diesel

heated units contains a

continuous coil of pipe which

forms a cold water jacket around

the outside of the heating area

and multiple spiral wound layers

to efficiently transfer heat to the

water inside the pipe. It is double

wrapped with ceramic blanket

insulation and a stainless steel cover.

The outside of these coils can become covered with

soot if the burner is out of adjustment or if it is fired by

diesel fuel. This can be cleaned by removing both end

caps on the coil enclosure and brushing or spraying

off debris, or by adding a soot removal agent (Part

#CB200) to the diesel fuel. Both a diesel fuel pressure

gauge and smoke test device is required for proper

burner adjustment on diesel heated units, and must be

performed by a qualified technician.

When the water is heated, scale (calcium) will begin to

form on the inside of the coil pipe depending upon the

hardness of the water in your area. To remove

buildup in the coil, use a scale remover (Part #CB100)

available at your authorized Hot2Go dealer. Perform

this descaling service only when a noticeable pressure

drop is detected across the coil. Follow directions to

avoid damage. Wear safety glasses.

It is important to be sure you prevent your coil from

freezing or blockage caused by scale buildup or ice as

this is excluded from your warranty. Ice can exert

extreme pressure from the inside of the coil pipe and

cause it to split and frozen flow switches or pressure

switches can malfunction which control the burner.

SYSTEM INFORMATION 8

These pictures show different reasons for coil pipe

failure:

TEMPERATURE SWITCH: The burner is equipped

with a high temperature limit switch, which will shut off

the burner when the water temperature becomes too

hot. Hot water machines are equipped with an

adjustable thermostat so that the operator can control

the outlet water temperature. The burner will

automatically cycle on and off to maintain the desired

temperature.

STEAM INSTRUCTIONS: If your unit is steam

capable, install the green steam nozzle, turn

thermostat to 250° F.

PRESSURE/FLOW SWITCH: The heater/burner is

equipped with either a pressure switch or a flow

switch. When the trigger on the spray gun is

squeezed, water begins to move through the coil and

is pressurized. The flow/pressure switch turns the

heater/burner on and begins to heat the water.

Whenever the water spray stops or if the water is shut

off, the burner will shut off. WARNING: Burner

should fire only when the trigger is squeezed and

spraying water, if it comes on at any other time,

shut off machine and have it serviced.

DIAGNOSTIC LIGHT: The burner diagnostic light on

the rocker switch (if equipped) can help in determining

problems with the burner. The red light indicates that

power is going to the fuel solenoid valve. The burner

should be firing and heating the water whenever the

red light is on. When the trigger on the spray gun is

released or if the temperature set point is exceeded,

the red light will go off and the burner will stop firing.

DIESEL FIRED BURNER: The diesel-fired burner is a

forced draft pressure-atomizing burner. Diesel fuel is

sprayed out of an atomizing nozzle, mixed with air,

and ignited by a high voltage spark. The flame is

directed towards the coils of pipe, which in turn, heats

the water flowing through it. Use clean

#2 DIESEL FUEL for the burner or

substitute #1 diesel, light fuel oil, or

Kerosene if diesel is not available.

AIR BAND adjustments may need to

be made to compensate for higher

elevations, or if more than a trace of

smoke is observed in the burner exhaust. The

ELECTRODES may need to be cleaned and adjusted

periodically. These adjustments have to be made

precisely and should be performed only by qualified

personnel. Set between #1 & #2 on the smoke gauge.

The FUEL PUMP, on diesel heated

units, is a self-priming, low volume

pump which is propelled by the burner

motor. The fuel pump pressure is

typically set at 125psi but can be

turned as high as 160psi during the

winter when the incoming water temperature is lower.

Before adjusting the fuel pressure, connect a fuel

pressure gauge and an outlet water temperature

gauge, turn the pump and burner on, and turn the fuel

pressure screw clockwise until the desired water

temperature is obtained. Air band adjustment may be

needed to maintain a clean burn. Be sure not to

exceed the recommended specifications of the

machine.

The FUEL FILTER will need to be replaced often if the

diesel fuel quality is poor. A fuel filter with a water

separator is recommended if the fuel quality is

consistently poor.

The FUEL SOLENOID is an electric fuel valve that

shuts off the fuel whenever the trigger on the spray

gun is released or if the set temperature on the heat

switch is exceeded.

Warning! When performing any tests on ignition

systems, do not touch the ignition rod. Ignition

circuit generates over 10,000 volts, electrical

shock can result!

The IGNITION TRANSFORMER provides a high

voltage spark that travels down the electrodes to ignite

the diesel fuel. Disconnect all power before servicing.

The 12V burner operates from the battery on the SH

and SK Series. The engine has a 10 to 25 amp

charging system that keeps the battery charged which

runs the burner. The transformer stops when the

trigger gun is released and is controlled through a high

amperage contactor. To help keep the battery fully

charged, and for safely cooling down the burner, turn

off the burner during the last minute of rinsing. When

leaving the machine unattended, shut off burner and

engine switch. Replace 12 VDC battery regularly (2

year maximum interval) on 12V burner systems to

help ensure consistent performance.

SYSTEM INFORMATION 9

PRESSURE DELIVERY SYSTEM:

DISCHARGE HOSE: Use only a wire braid hose

rated for the output pressure and temperature of the

machine. Additional hose lengths can be added with

quick twist couplers with a minimal loss in pressure of

about .5 PSI per foot. Inspect hoses for wear and

replace if necessary. Avoid kinking or running over

the hose to extend the hose life.

WARNING: Hot2Go hot water machines require a

special 250° rated hose. If the hose is not

replaced when worn it may burst and serious

injury and burns could result.

QUICK COUPLERS: The swivel

connectors on the high-pressure hose

and quick couplers on the spray nozzle

make it easy to change nozzles or hoses. When

connecting hoses or nozzles, be certain that the collar

on the quick couplers snap into the locked position to

prevent them from becoming loose. If the quick

connect begins to leak, replace the O-ring (specify

Viton or EDPM material) located in the female socket

coupler. Grease the coupler periodically to make it

work smoothly. Replace if it becomes worn. Twist

couplers are also used on most wands so they can be

interchanged.

TRIGGER GUNS: The trigger gun is merely a valve

that turns water spray on and off. If it begins to leak or

fails to shut off, replace or repair the valve assembly.

Machines that spray steam only are equipped with an

open gun that does not shut off the water spray.

SPRAY WAND: Spray wands are available in

different lengths (2 to 6 foot) and with variable

pressure adjustment for various cleaning applications.

The dual wand has a low-pressure and high-pressure

nozzle. When the dual wand is installed on the

machine, the output pressure can be lowered simply

by turning the valve on the dual wand to divert water

into the low-pressure nozzle. This lowers the pressure

(psi) but has little or no impact on the flow (gpm) or

outlet water temperature on hot water machines.

The short wands are ideal for washing in confined

areas such as a car lot. The longer wands help to

clean areas that could not normally be reached.

WARNING wands less than 48” long should not be

used with machines producing over 3200psi.

NOZZLES: The spray nozzle

is a precisely machined

orifice made of hardened

stainless steel. The orifice

size is matched to the output

of your machine to attain the

proper flow and pressure in which your machine was

designed. The orifice, or hole, of the nozzle will

enlarge with wear. For optimum performance, replace

the spray nozzle to maintain the full output pressure of

your machine. The nozzle installed on your machine

from the manufacturer is designed to allow only about

90% of the water being pumped to discharge out of

the nozzle. The remaining 10% is bypassed back into

the inlet water supply by the unloader/regulator valve.

If an incorrect nozzle size is used, the maximum flow

and pressure of the machine cannot be achieved and

the unloader valve can wear prematurely. When

replacing the nozzle, match to one size under the flow

and pressure output of the pump.

The nozzle is usually connected to the wand with a

quick coupler. Be sure the collar on the quick coupler

snaps into the locked position, or the nozzle could be

lost when the trigger on the spray gun is squeezed.

Never connect the spray nozzle directly to the trigger

gun without a wand or injury could result. Never place

hands or fingers over the nozzle tip.

The nozzles generally come in four different spray

angles: 0°, 15°, 25°, and 40°. The different spray

angles of a given size of nozzle do not change the

output pressure of the machine, just the impact force

and surface coverage of the water spray.

The optional 0° nozzle sprays a straight stream which

impacts the surface very hard but does not cover a

very wide area. Use the 0° red nozzle with care

because it can damage the surface you are spraying

with its high impact and long reaching spray.

The 15° yellow nozzle sprays out a flat stream at a 15°

pattern. It gives you less impact power than the

above, but covers a wider area with one pass of the

spray wand. As you back away, the spraying nozzle

from the surface, the spray impact will decrease.

The 25° green nozzle is wider than the 15° and is

most commonly referred to as the “steam nozzle”.

The steam nozzles are sized to spray less water than

the other high-pressure nozzles, so the water is

discharged at a higher temperature. (Up to 250°F.)

The 40° nozzle spreads the water stream over a wide

area to give you less impact for delicate surfaces.

Never connect the spray nozzle directly to the

trigger gun without a wand or injury could result.

Never place hands or fingers over the nozzle tip.

Never lock any gun in the on position for any

reason. Never point spray at a person or any

part of the body.

SYSTEM INFORMATION 10

OPTIONAL ACCESSORIES:

HEATING COIL PROTECTION:

Protect your heating coil by removing debris or

minerals from inlet water by adding a filter or anti-

scale cartridge. The universal bracket and filter

housing kit (p/n AF001) attaches to most 1” to 1½ “

tubing to fit most pressure washer frames, then

choose the filter insert that will most benefit you.

▪ A 10-micron filter cartridge removes debris, ideal

when using sandy, non-potable, or well water (p/n

VFH11)

▪ The anti-scale cartridge removes minerals to prevent

scale buildup (p/n VFD50)

WET SANDBLASTER: The wet

sandblaster is a system that introduces

sand (or other media such as baking

soda) into the water stream for abrasive

blasting. It is especially effective for

graffiti or paint removal. Performance of the unit is

directly related to the output of your high-pressure

washer. The sand is mixed with the water at the sand

head in a tungsten carbide nozzle.

A vacuum is created in the sand nozzle, which draws

a sand and air mixture up the sand hose. If the sand

becomes wet or the sand nozzle becomes plugged,

the vacuum will be lost and the sand will quit flowing.

The sand probe can be poked directly into a bag or

bucket of sand to draw it up the sand hose. Do not

cover the air intake port on the top of the sand probe

or the sand flow will be disrupted. Uncoil the sand

hose completely before use to improve the sand flow

and replace the sand hose when it becomes worn.

The carbide sand-mixing nozzle can be unscrewed

and replaced when worn.

Use bagged silica sand for best results through the

sandblaster. Use 16 to 20 grit (course) sand for rust

or concrete. Use 30 grit (fine) for fine metal surfaces

or wood. Do not use wet sand or mix different grits of

sand. A sand hopper is available for convenient sand

storage. An air valve is available for adjusting feed

rate on the hopper and should be fully open when

using fine media such as baking soda. Always use

safety goggles and protective clothing when

operating the wet sand-blaster.

TURBO NOZZLE: (please note temperature

limits) The turbo nozzle multiplies the power

of your machine by rotating the spray jet and

making the water impact a surface harder to

give better cleaning results.

“Turbo Laser” type nozzles cannot be used with water

over 190° or the life of the turbo nozzle will be greatly

decreased and the warranty voided. The “Rotomax”

type nozzle can be used up to 170°. Turn off burner

or reduce temperature setting before using. Simply

remove regular spray nozzle, replace with the turbo

nozzle and squeeze the trigger on the spray gun. Do

not point the turbo nozzle upward when starting.

EXTENSION HOSES: connecting additional hose

lengths by means of twist couplers can extend the

length of your high-pressure discharge hose. Hose

extensions generally come in 50’ and 100’ lengths.

Specify maximum pressure and temperature of your

machine when ordering.

Low-pressure inlet garden hoses are available in 50’

and 100’ lengths. Premium quality, 200psi rated

hoses are recommended. WARNING! If your unit is

equipped with 250°F steam option, only use

minimum 250°F rated high-pressure hose.

HOSE REELS: Hose reels are

available for convenient and

quick storage of both discharge

and inlet hoses. Different hose

reels options are available for

trailer mounting, machine

mounting, wall mounting, or as

base mount options. To keep

the hose from unreeling, lock

the drum in place and secure

the gun or the end of the hose

or it may drag on the road. The

low-pressure hose should be of sufficient quality that it

will not flatten out when reeled up, or water supply to

the machine will be cut off.

If the reel swivel begins to leak, replace or connect the

hose directly to the machine until the leak is repaired.

Hose reel swivels with lubrication are pre-lubricated by

manufacturer. Additional lubrication intervals depend

on application and frequency of use. However, a

minimum for re-lubrication, with standard Moly Lith

grease, at 40 hours is recommended. Do not over

grease. Using a hand held grease gun, dispense one

pump of grease into the grease fitting. Depress the

ball bearing at the end of the grease fitting to allow the

grease and air to escape

ACCESSORIES 11

HYDRO TWISTER –Surface Cleaners:

The Hydro Twister® is a flat

surface cleaner that connects

to a pressure washer and uses

a spray bar rotating at a high

speed within 1” of the ground.

It will clean concrete more

consistently than an operator

with a spray wand, with less

fatigue, and 10-20 times faster.

Simply move the twister over

the surface and watch a clean

path appear behind the unit.

The Hydro Twister can be used

with hot water up to 210º on

most models for extra stubborn

grease or grime, eliminated the need for soap

pretreatment in most applications. Rated to be used

with a pressure washer up to 4000psi and up to 6gpm.

See your dealer for proper nozzle size configurations

to match your pressure washer.

Recovery surface cleaners are also available through

the Hydro Vacuum® product line.

HOT LINK™HEAT EXCHANGERS:

The Hot Link™ attaches to your cold water pressure

washer and converts it into a hot water pressure

washer. The cold water pressure washer provides

high-pressure water into the Hot Link™ which heats

the water before delivering it through the spray gun

and wand. The Hot Link™ is flow controlled so when

the gun is pulled, the burner automatically starts and

stops when the gun is released. Simply attach to the

Hot Link™ with the jumper hose, provided, to almost

any cold water pressure washer, and attach the

pressure washers hose, gun, wand and nozzles to the

outlet on the Hot Link™. The Hot Link™ system

continuously heats at a 100°F temperature rise and

pressure rating up to 4350psi. (Spray gun and hose

must be rated for

at least 200F

and pressure

washer must not

exceed 4350psi).

HYDRO VACUUM® WASTEWATER RECOVERY

Hydro Tek manufactures Hydro

Vacuum®, a product line of

mobile wastewater recovery

accessories. Starting with

containment berms to divert

wash water away from storm

drains and toward a vacuum

pickup device. The vacuum

system can be used to simply

pickup and transfer the water to

a bulk tank or choose a system

to filter the water for washing

reuse or sanitary sewer disposal.

Vacuum system choices are

either fully portable (on wheels)

or truck or trailer mount systems.

Dispose of collected wastewater properly: Permits can

be obtained to dump wastewater into a sanitary sewer

system if properly treated

and tested. It is illegal to

allow wash water to run into

storm drains.

ACCESSORIES 12

TRAILERS: Hot2Go trailers are designed to match

your Hot2Go washer and increase productivity.

Several trailer and tank skid configurations are

available.

Every trailer comes with a 4 pole

flat electrical receptacle.

Because of the vast array of

different connectors, you may

need to have one installed by

your dealer or purchase at a local

auto parts store and install

yourself.

Be sure that the trailer you order conforms to your

particular State Department of Transportation

regulations, including but not limited to braking and

lighting requirements. If water is being transported on

the highway, trailer brakes are recommended. Adjust

brake drums as required.

Before taking trailer on the road, be certain that the

hitch on your tow vehicle is rated for the full trailer

weight and of the proper height so that the trailer

remains level when hitched, or wheel damage could

result. Trailer tongue weight on the tow vehicle hitch

should never be under 8% of the total trailer (loaded)

weight. Insufficient tongue weight can result in

“fishtailing” and loss of control of the trailer AND tow

vehicle.

BALANCING: Keeping tires balanced will increase tire

life and help trailer tow with more control.

Before each use: Check air pressure in tires. Check

all bolts including the lug nuts for tightness and

condition periodically. Double check safely chain and

wire harness before departing. Check latch on

coupler and adjust if required to fit your trailer ball

properly. Never tow without properly adjusted rear

view mirrors, brake actuators, or lights.

Grease wheel bearings as required.

MAINTENANCE LOG 17

While your pressure washer has been produced with

quality materials and craftsmanship, you as the owner

have certain responsibilities for the correct care of the

equipment. Attention to regular preventative

maintenance procedures will assist in preserving the

performance of your equipment.

Contact your Hot2Go dealer for maintenance. A small

investment in preventative maintenance will add many

hours to the life of your pressure washer. Perform

maintenance more often under severe conditions. Do

not spray high-pressure water onto the machine. Not

all maintenance items apply to all machines.
