Important Safety Rules
4
1.) Read owner's manual completely.
Serious injury or death can result if safety instructions are not followed. You must be
16 or older to operate this machine. Keep untrained people away.
2.) Skin puncture hazard.
High pressure fluid can inject under skin resulting in serious injury including
amputation. Do not direct spray at people or animals.
-If skin injection happens, seek IMMEDIATE surgical treatment.
-Do not check for leaks with hand. Instead, use a piece of cardboard to check for
leaks.
-Do not use unit if exterior hose damage is evident. Make sure all fittings are tight
before starting. Relieve system pressure before servicing.
-Know how to stop engine and bleed pressures quickly. Be thoroughly familiar with
the controls.
-Make sure accessories meet the unit's temperature and pressure limits.
-Stop engine, bleed pressure, and engage spray gun safety lock before leaving unit
unattended.
3.) Risk of fire and explosion.
Hot exhaust fumes from engine can cause fire. Gasoline is highly flammable and
explosive. You can be burned or seriously injured when handling fuel.
-Position muffler at least 7 feet from combustible objects.
-Before adding fuel, stop the engine and keep heat, sparks, and flame away. Do not
add fuel when engine is running or still hot. No smoking near engine.
-Do not pump fuel directly into engine at gas station. Static charge can build and
ignite fuel. Use a UL approved fuel container to transfer gas to the engine. Wipe up
fuel spills immediately.
-Only store and handle fuel outdoors. Gasoline vapors can ignite if they collect
inside an enclosure. Explosion can result.
-Do not change or add to exhaust system. Fire can result.
-Do not change or add fuel tanks or fuel lines. Fire can result.
-Before each use, check fuel tank and fuel lines for leaks. Any fuel leak is a fire
hazard. Fix any fuel leaks before starting engine.
-During transportation take precautions to make sure pressure washer will not tip
over and cause a fuel leak fire hazard.
4.) Poisonous gas.
This machine gives off carbon monoxide, a poisonous gas that can kill you. You
CANNOT smell it, see it, or taste it.
-ONLY run machine outdoors and away from air intakes.
-NEVER run machine inside homes, garages, sheds, or other semi-enclosed spaces.
These spaces can trap poisonous gases, EVEN IF you run a fan or open doors and
windows.
If you start to feel sick, dizzy, or weak while using this machine, shut it off and get to
fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.

5.) Risk of exposure to dangerous chemicals.
Serious injury or death can result if chemical manufacturer instructions are not
followed.
-Wear protective gloves when handling and cleaning with chemicals.
-Understand all safety hazards and first aid for all chemicals being used.

devices.
7.) Flying objects.
Small particles may fly out while spraying. Wear safety glasses. Serious eye
injury can occur.
Make sure nozzle is secure before squeezing trigger. If nozzle is not secure it
will become a projectile.
8.) Fall hazard.
Pressure washer creates puddles and slippery surfaces. Keep good footing
and balance. Serious injury can occur.
-Wear footwear cabable of maintaining a good grip on wet surfaces.
-Gun kicks back. Hold with both hands.

Water Supply
1.) Make sure the water supply is clean. Debris can cause excess pump wear and reduce
performance.
2.) An insufficient water supply will damage your pump. Make sure the water supply is steady and is
20% over the rated flow of your pump. Use a stopwatch to time how long it takes to fill a 5-gallon
bucket with your garden hose. The bucket must fill faster than the times listed in the table below.

3.) The water supply garden hose must have an inside diameter of at least 5/8”. If the hose is more
than 100 ft. long, the diameter must be at least 3/4”.
4.) Never use a reservoir tank as a water source. Drawing water out of a tank may cause pump
cavitation and damage to your pump. This pressure washer is designed for a pressurized water
source such as a city water faucet. However, the water source pressure must not exceed 115 psi
(8 bar).
5.) Always use a flexible rubber hose for your water supply. Do not use rigid piping.
6.) Always keep a fire extinguisher rated “ABC” nearby.

Applying Chemicals
1.) Install the black nozzle to spray chemicals onto the cleaning surface.
2.) Start the pressure washer according to the start-up instructions.
3.) Submerge the chemical hose in cleaning solution.
4.) Squeeze the spray gun trigger. The chemical injector will draw the chemical into the water stream.
5.) Apply chemicals evenly onto the cleaning surface. Allow the chemicals to react with the dirt, then
clean at high pressure with green nozzle.
6.) Never use more chemical than is necessary to clean the surface.
7.) To clean the chemical injector, draw water through the strainer until all the chemical is purged from
the system.
Risk of exposure to dangerous chemicals.
Serious injury or death can result if chemical manufacturer instructions are not
followed.
-Wear protective gloves when handling and cleaning with chemicals.
-Understand all safety hazards and first aid for all chemicals being used.
-When cleaning filters, check if chemicals have been used and take any
precautions that are recommended by the chemical manufacturer.

Maintenance Mode
Before performing any maintenance on the pressure washer, it must be placed in maintenance mode.
1.) Turn off engine.
2.) Turn off water supply.
3.) Squeeze trigger to relieve system pressure.
4.) Shut off fuel valve.
5.) Unplug spark plug wire from spark plug, (see engine owners’ manual).
Maintenance Schedule
What to Check
When to Check
What to Do
Inlet Filter
Each Use
Visually inspect and clean inlet filter with clear water.
Pressure Hose
Each Use
Visually inspect pressure hose and hose couplings. Replace
hose if any of the following is evident:
hose coupling is damaged, wire mesh is exposed or
damaged, hose is permanently kinked or flattened, outer
hose cover is blistered or loose.
Bolts
Each Use
Tighten any loose bolts.
Engine Oil
See engine manual
See engine manual for oil change instructions
Pump Oil
After 1st 50hrs,
then 3mo/500hr
Change pump oil. See pump oil change instructions on next
page.

Maintenance and Storage
11
Pump Oil Change
1.) Place a suitable container below the pump to catch used oil, then remove the oil fill cap and oil drain plug.
2.) Allow the used oil to drain completely, then reinstall the drain plug and tighten securely.
3.) Please dispose of used oil in a manner that is compatible with the environment. We suggest you take used
oil in a sealed container to your local recycling center or service station for reclamation. Do not throw it in
the trash, pour it on the ground or down the drain.
4.) With the pump in a level position, fill to the halfway point on the oil sight glass (see pump oil capacities
below). For Comet or NorthStar pumps use Universal Tractor Transmission Oil or Mobil1 synthetic oil
(15W50). For Cat pumps use SAE30 non-detergent oil or Cat Pump Oil Item# 22158. For General Pumps
use SAE30 non-detergent oil. For Powerhorse pumps, use SAE30 non-detergent.

Maintenance and Storage
12
Checking Oil Level for A157711 & A1577110
1.) Turn off engine, allow it to cool and disconnect the spark plug wire.
2.) Twist the dipstick cap until the arrow on the cap lines up with the arrow on the breather plug.
Remove the dipstick from the breather plug. Then remove the breather plug from the pump.
3.) Wipe the dipstick off with a clean dry cloth. Insert the dipstick into the pump housing and remove it.
The oil level should be at least to the lower “L” notch on the dipstick, but not above the upper “H”
notch. Add above recommended oil as needed.
4.) Thread the pump breather plug tube back into the pump housing.
5.) Align the arrow on the dipstick cap with the arrow on the breather plug tube, insert it, and twist it to
secure. Reconnect the spark plug.
Long Term Storage
Follow the engine owner’s manual for storing the engine.
Winter Storage
Protect your pump, hose, and gun from freezing.
Items needed: 12” piece of garden hose or equivalent, funnel and RV antifreeze (approximately 6 oz.)
1.) Follow the storage instructions listed above.
2.) Disconnect spark plug cable. Make sure the engine start switch is OFF, and the fuel valve is OFF.
3.) Attach the garden hose with funnel to the pump inlet (see illustration).
4.) Pour RV antifreeze into the funnel, pull the engine recoil until antifreeze comes out the pump outlet.
5.) Drain all water from the high-pressure hose. Depress trigger on gun and drain all water out of
gun/lance.
