BASIC ELEMENTS OF A PRESSURE WASHER
High Pressure Pump: Increases the pressure of the water
Engine: Dr iv es the hi gh pressure pump .
High Pressure Hose: Carries the pressurized water from the pump lo the gun
and spray wand .
Spray Gun: Connects with spray wand to control water flow rate, direction, and pressure.
Quick Connect Spray Wand: Spray wand is equipped with a female quick connect
coupler on the end . This allows the user to quickly change out
High - pressure nozzle for different spray patterns and change the soap noz 乙 le for
the low pressure and chemlcal /soap applications . see how to use spray wand
paragraph In this section.
Chemical Hose: Feeds cleaning agents into the pump to mix the pressurized
water. see how to apply chemical /cleaningsolvent in this section of this
Manual.
BASIC ELEMENTS OF ENGINE
Refer to the engine manual for location and operation of engine
-8-
Choke Control Lever: Controls engine speed.
Starter Grip: Pulling starter grip operates recoil starter to crank engine.
Fuel Valve Lever: Opens\Closes connection between fuel tank and carburetor.
Engine Switch; Enables and disables igniton system .
PRESSURE WASHER TERMINOLOGY
PSI: Pounds per square inch. the unit of measure for water pressure , also used for
air pressure hydraulic pressure, etc.
GPM: Gallons per minute, the unit of measure for the flow rate of water
CU: Cleaning units. gpm multiplied by psi
Bypass Mode: In bypass mode, the pump is reci 『 culating water because the trigger of the
spray gun is not pulled. If unit is left in bypass mode for more than two(2)minutes, the
water temperature will rise to a dange 『 ous level and could damage internal components of
the pump . Any damage topump due to these causes will not be covered under warranty.
Do not allow unit to operate in bypass mode for more than two
mmmnmJ minutes at any time. Overheatln-g of pump can cause damage
to pump.
Thermal Relief Valve: In an effort to prevent extreme damage, pumps are
equipped with a thermal relief valve. This valve will open when the temperature
inside the pump rises too high. This valve will then release a gush of water in an
effort to lower the temperature inside the pump. Immediately after this occurs,
the valve will close.
Chemical Injection System: Mixes cleaners or cleaning solverts with the
pressurized water to improve cleaning effectiveness.
Water Supply:AII pressure washers must have a source of water. the minimum
requirements for a water supply are 20PSI and 5gallon per minute.
PRESSURE WASHER OPERATING FEATURES
PRESSURE ADJUSTMENTS
The pressure setting is preset at thefactory to achieve optimum pressure and
cleaning. if you need to lower the pressure. it can be accomplished by these
methods
1. Back away from the surface to be cleaned. The further away youare, the
less the pressure will be on the surface to be cleaned
,-Do not attempttoincreasepumppressure. A higherp 『 !ssure
setting than the factory set pressure may damage pump.
-9-

2. Reduce the speed the gasoline engine (RPM). Slow the engine down and
the water pressure will go down with it
3. Change to the 40° white nozzle, This nozzle delivers a less powerful stream
of water and a wider spray pattern
4. Adjust the pressure regulator on the pump. Turn the pressure regulato 『
knob counte 『 clockwise to lower pressure. once you have finished using your
pressure washer, return the pressure regulator to its o 『 iginal position by
turning it clockwise.
_
Do not try to turn pressure regulator knob
past the built-In stop or damage to pump
will result
TO USE SPRAY WAND
Your pr_essure washer is equipped with up to five spray nozzles. Each nozzle is
color c_oded . and delivers a specific spray pattern for a particular cleaning
purpo~e. The size of the nozzle determines the size of the fan spray and the
pressure out of the nozzle. The· 0°, 1 ff, 25°, and 40°nozzles a 「 e highp 『 essure
nozzles,the chemical nozzle is a low pressure nozzle.
The nozzles are housed in receptacles on the panel of the pressure washe 『 handle.
Colors on the panel identify nozzle location and spray pattern.
Risk of injection or Injury to person. Do not direct discharge
nmmDB stream toward persons, unprotect skin, eyes, or
any pets or any animals. Serious injury can occur.
CHANGING NOZZLES
B!mm DO NOT attempt to change nozzles while pressure washer is
running. Turn engine off before changing nozzles
1.Pull quick connect coupler back and insert nozzle
2.Release quick connect coupler and twist nozzle
to make sure it is secure in coupler.

and is extremely powerful. It covers a very small area of
cleaning. This nozzle should only be used on surface that
can withstand this high pressure such as metal or concrete.
Do not use on wood .
15 °nozzle-yellow. This nozzle delivers a powerful 15
degree sp 『 ay pattern for intense cleaning of small areas .
This nozzle should only be used on areas that can withs-
tand the high pressure from this nozzle.
25°nozzte-green. This nozzle delivers a 25 degree
spray pattern for intense cleaning of larger areas. This
nozzle should only be used on areas that can withstand
the pressure from this nozzle.

HOW TO APPLY CHEMICALS AND CLEANING SOLVENTS
rJDmllm Applying chemicals or cleaning solvents is alow pressure operation.
rJDmllm Use only soaps and chemicals designed for pressure washer use. Do not use bleach.
To apply chemicals:
1.Press chemical hose onto barbed fitting located near
hi gh p 『 essure hose connection of pump as shown .
2.Place other end of chemical hose with filter on
it into container holding chemical/cleaning solution .
!im+lm The chemlcal/water ratio is 7:1,for
every 7 gallons of water pumped, 1 gallon
of chemical/ cleaning solution will be used.
3.lnstall low pressure(black) nozzle into qu i ck connect filling of spray wand, see How To
