Tighten all connections and replace worn parts before
starting the machine. Sudden release of high pressure
streams may result if connections detach during use.
This can cause serious injury. Never disconnect any part
of the unit while the machine is running or before relieving

Read all safety instructions throughout the manual.
Place unit on dry, rm ground for optimum lubrication of pump.
The pressure washer should be as close as possible to the water
supply.
Tighten all hoses and connections. Check parts and replace if
needed.
Check oil levels prior to each use. Oil should cover the indicator
line on the dipstick.
To prevent damage and excessive hose wear, position the pres-
sure washer so the hose does NOT extend across trac areas.
Make sure there are no kinks or twists in the hose.
Check to determine if the water supply to the pressure washer
exceeds the output of the pump. The output of this unit is 2.1
gpm (gallons per minute), so the water supply must deliver at
least 2.5 gpm.
Note: This unit is supplied with a“Total Stop System” (TSS) that
allows the pump to run only when the gun trigger is squeezed.
Releasing the trigger will temporarily stop the machine.
Squeeze the trigger on the gun to restart the machine.
Avoid rapidly squeezing the trigger to prevent damage to
the TSS.

Calculate gpm ow rate by running the water supply into a
pail for one minute. Measure the gallons in the pail. If it is at
least 2.5 gallons in the minute, your supply is adequate. Your
water supply must be clean and free of debris. Use water
with a temperature of less than 140°F.

Position the unit so the operator has easy access to the pressure
washer and its controls.
Do not use the pressure washer outdoors if it is raining, and do
not spray the motor or any of its connections.
Do not use chemicals or agents which are not compatible with
Buna-N, PVC (polyvinyl) or neoprene covering of the hose.
Do not use acids or caustic material with this unit. Damage due
to use with incompatible material will not be considered for
warranty.
Always test a small area to avoid possible damage to surfaces.

Your pressure washer Pump Unit is supplied with a downstream
low pressure soap/chemical injector. This is used for adding soap/
chemical to the water after it has owed through the pump.
Note: The injector works only with the supplied black soap nozzle.
To draw soap/chemical into the water stream, insert the lter end
of the detergent hose into the soap/chemical. Do Not use powders,
granular, high viscosity detergents or acidic based detergents/
chemicals in the injector.
Note: Follow the soap/chemical manufacturer’s instructions for
correct dilution ratios.
To ush the injector, remove the detergent hose and lter from the
detergent/chemical tank and place it in a container of clear
water. Run water through the entire system to ush out the
soap/chemical you were using.

Chemicals: Cleaning agents are most eective when the surface is
rinsed rst to loosen dirt. After pre-rinsing to loosen dirt, then clean
with the detergent.
Detergent should be applied from the bottom to the top of the
washing area. Apply detergent and allow the detergent to react
with the dirt, then rinse from the top to the bottom. This detergent
applying and rinsing technique will help to avoid streaks and skips
in the washing area.
Never use more detergent than is necessary to clean the surface.
Always follow directions supplied by the detergent manufacturer on
the container.
Cleaning: For best results, hold the nozzle 6 – 12”away from the
washing surface and use long, slow deliberate side to side strokes,
similar to using a paint sprayer. This technique will provide the most
eective cleaning impact and minimize streaks and skips in the
cleaning process.
Wax: If the pressure washer is used to apply wax, the gun should be
held further from the surface to optimize the“misting”eect during
application. For best results, follow the directions supplied by the
wax manufacturer.

rouTIne CheCks before every use
Check the water inlet screens for debris. Clean as needed using
water and a toothbrush.
Note: Damage can occur if run without lter.
Check the nozzle for debris and signs of extensive wear. A worn
nozzle will result in poor performance. Only check the nozzle
with the motor turned to the“OFF”position and the pressure
relieved from the system!
Check all ttings and connections for leaks and worn sealing
areas. Replace worn components.

MaInTenanCe
Changing oil is one of the most important and least expensive
maintenance items. It will prolong the life of your pressure washer.
Change oil after rst 50 hours of break-in period, and then every 200
hours or once per year. Demanding environments may require oil
changes more frequently.
To change oil: Remove the 17mm oil drain plug on the bottom
of the Pump Unit. Rell with 10 ounces of SAE20 or 30W
Non-Detergent oil.
Winterizing or long time storage: Drain all water out of pump. Flush
pressure washer with a 50/50 mix of RV antifreeze and water. Relieve
system pressure by squeezing gun trigger. When ready to use again,
ush pressure washer with clean water to remove antifreeze.
Note: See pg.12“Storing the Pressure Washer”

sTorIng The pressure Washer
Severe damage could occur by water freezing inside the
components. To prevent costly repairs, follow these steps:
Make sure the unit is“OFF,” water supply is disconnected, and
system pressure has been relieved by squeezing the trigger on
the gun.
Install a suction hose from the pump inlet (garden hose tting)
into a gallon of NON-TOXIC RV anti-freeze. Following operating
instructions start the machine and squeeze trigger on the spray
gun allowing the pump to draw anti-freeze though the entire
system. Once the anti-freeze appears at the end of the wand,
turn the machine “OFF”.
Squeeze gun trigger to relieve pressure from system.
Disconnect the high pressure hose from the high pressure outlet
and put the hose, gun/wand and owners manual in a secure
place to prevent unauthorized people from using the machine.
When ready to use the pressure washer again, reinstall the
high pressure hose and water supply hose. Turn the water on
and squeeze the trigger on the gun to send water through the
system. Dispose of the anti-freeze/water solution safely where it
will not be harmful to the environment, people or animals.
Power o machine before starting.

sTarTIng The MaChIne afTer aperIod of non-use
Long periods of non-use can cause calcium and iron
deposits inside the pump. Starting the machine could
cause damage to the pump. Insert a at blade screw
driver through the hole in the motor end housing and
rotate the motor one revolution clockwise and
counter-clockwise. Remove screwdriver and start the
motor. It should start up easily.
