Engine exhaust from this product contains chemicals known
to the State of California to cause cancer, birth defects, or
other reproductive harm.
Thank you
Thank you for selecting our products. Our personnel have proudly made every effort to ensure
that your new pressure washer is of the quality you expect. But things do occasionally go wrong.
This is why every pressure washer is covered by a limited warranty. Among other things, this war-
ranty provides for the replacement of parts found to be defective during the operation of your new
pressure washer. Please note that the owner/operator has certain obligations under the terms of
the warranty. Be sure to read this manual for directions on proper installation, start-up, use, and
storage of your pressure washer.
Your new pressure washer was tested after production for proper pressure and flow. Please note
that this process will sometimes leave a water residue in the pump. The dealer you have purchased
your new machine from should review with you the proper installation, start-up, use, and storage.
Most ‘big’ problems occur when shortcuts are taken in one of these processes. If a problem occurs
that you need some assistance with, please feel free to contact us at the listing below:

Statement of Warranty

WARNING
The following warnings must be followed. Failure to follow these warnings could result in
serious personal injury or death!
Never allow children or untrained personnel to operate machinery.
Gun kicks back--hold with both hands.
Electrical equipment can cause shock and sparks.
Do not bypass or remove the grounding prong in any electrical plug.
Keep electrical plugs, connections, and cords out of water and moisture.
Disconnect from power source before servicing.
Inspect and repair damaged or exposed electrical components prior to use.
Never splice electrical cords on pressure washers.
Be sure electrical service is adequately sized for the equipment.

Exhaust gasses can cause death or serious injury.
Use only in well ventilated areas or vent the exhaust to the outside.
High pressure water can cause death or serious injury.
Warning--high temperature water.
Wear protective clothing and face shield.
Do not direct water stream toward self or others.
All hoses should be secured in the lines to be cleaned at least five feet.
Pressurized fluid streams and ruptured pressure vessels can cause death or serious
injury.
High pressure fluid can create a high pressure stream or ruptured vessel.
Wear a safety face shield.
Relieve pressure before servicing.
Do not modify, repair, or rework vessel or change safety relief or pressure setting.
Do not direct stream toward self or others.
Fire can cause death or serious injury.
Kerosene, fuel oil, and gasoline will burn when ignited.

Initial setup and operation of your new pressure washer
When you receive your pressure washer, be sure you check for concealed freight damage. Any
damage should be noted with the delivering carrier. If you have any questions related to freight,
call the 800 number listed in the front of the manual.
Check all oil levels in the pump or engine, if applicable. Failure to check all levels will result in
equipment damage. Most pumps are shipped with oil from factory and the crankcase are sealed,
you may have to remove a shipping plug and install a dipstick in the pump. Most engines are
shipped without oil,be sure to check these oil levels.
Your water supply must provide water to the equipment that exceeds the Gallon Per Minute
(GPM) rate of your machine. You can check your GPM by using a five gallon bucket and a
timer. If your machine is five GPM or less and the bucket fills in less than a minute you have
adequate supply. Some systems are effected by things like washing machines, livestock water-
ing systems, and flushing toilets. Be sure the supply is still adequate when these operations are
taking place. The water temperature cannot exceed 145 degrees Fahrenheit. Water pressure
should not exceed 60 PSI. Failure to secure adequate water supply will result in pump
damage. Do not run pump dry.
Your water should not contain particles larger than 80 microns. Although there are small filters
installed on pressure washers that filter the water, they can only filter poor quality water for a
short period of time before they clog. Clogging would result in damage to the machine.
Therefore you should insure no sand or scale particles are present in the water supply.
Hook a garden hose from the hydrant to the machine, when doing this be sure to check the
inlet water filter or screen. This hose should be at least 5/8’ diameter and a length at least 15
feet. This 15 foot length helps isolate the water supply from pulsations from the pump. Many
states require a Vacuum Break or backflow preventer be installed at the hydrant,
before the garden hose, to insure the water source cannot be contaminated. Be sure to check
local and state regulations upon installation.
Turn on the water supply and open the trigger gun, this will purge all the air from the system.
Look for water leaks and stop any leak found. Leaks can cause erratic pump behavior.
Turn equipment off and allow time to cool before refueling. Fill the burner tank labeled ‘fuel’.
Be sure the fuel is clean and free from moisture and particles. Use only No. 1, No. 2 or
kerosene, no other fuel should be used! There is a fuel filter in the line. Check this filter
prior to operation. Do not run fuel pump dry, doing so will damage the fuel pump.
Prior to starting the motor, check the oil in the pump. Be sure it is at the proper operating level
and that the correct oil is being used. Check the pump breakdown for the proper type of oil.

Shut down procedure
Initial setup and operation of your new pressure washer, cont.
The pressure was set at the factory during the testing procedure, no adjustments to the machine
should be required for operation. During operation the burner may cycle on and off. The
adjustable thermostat may be set to desired temperature. Water temperature will not exceed 190
degrees, the safety switches will shut the burner down. During operation do not leave the
machine running for more than two minutes without the trigger gun being pulled.
Although your machine has a by-pass valve on it and may have a thermal relief system, this can
cause extensive pump damage. If machine will not be discharging water for more than
two minutes, shut the machine off.
Your machine is supplied with interchangeable spray tips. The colored tips are for high-pres-
sure rinse at different spray angles. The red tip sprays at zero degrees; yellow, fifteen degrees;
green, twenty-five degrees; and white, forty degrees. The yellow tip is used for most standard
applications. Be sure the quick coupler is fully engaged before pulling the trigger
gun. Failure to do so may result in the tip becoming a projectile and may be lost and damage
to property and persons may occur.
Your pressure washer is supplied with a downstream chemical injector. The 1/4” clear vinyl
tube is to be inserted into the desired chemical to apply. The chemical injector will only open
up and allow chemical into the line when the forward handle (see wand breakdown page 10) on
the wand is turned counter clock wise.This enables the pressure to drop to approximately 250
PSI and draw chemical, this is a valve that allows the water to flow through the wand and
through the chemical tip. The rate of injection can also be set by turning the knob that the
clear vinyl tube attaches to. Be sure to flush injection system with clear water after use.
If an accurate injection rate is desired, use this formula.
(GPM x 128) / ounces drawn in one minute = x: 1
IE: If a 2.0 GPM machine draws eight ounces of chemical in one minute: 2 x 128
8 = 32:1
1. Turn off the power switch on the burner. Continue to run the pressure washer and pull
the trigger to circulate water through to cool the coil.
2. After several minutes when water is cool, shut off the pressure washer motor.
3. Shut off water supply and disconnect garden hose.
4. Be sure to double check for water leaks or oil leaks that should be repaired before the next
operation.
If you are going to store the machine for extended period of times in cold climates be sure to
winterize the equipment. A fifty percent anti-freeze solution may be drawn in through the inlet
of the pump using a short remnant of garden hose. This fluid should be run through the pump
and coil. When the fluid is discharged from the coil discharge your machine is winterized. Do
not allow machine to freeze.
The pump oil should be changed after the first fifty hours of operation, then every year for
average service or more frequently for extensive use or hostile environments (dusty or high
moisture).
