Important Safety Rules
WARNING
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.

Important Safety Rules
WARNING
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.
-When cleaning filters, check if chemicals have been used and take any
precautions that are recommended by the chemical manufacturer.
-Different chemicals may interact dangerously with each other, always follow
chemical manufacturer directions before switching chemicals.
-Calculate the correct amount of chemical to mix, dispose of excess chemical
per the manufacturer instructions.
-Never spray flammable liquids.
6.) Risk of electrocution.
Electricity can kill you. Keep water away from electrical outlets and electrical
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.
-Do not overreach or stand on unstable supports.
-Do not stand on ladders or scaffolding.
-Do not place pressure washer on soft or unstable ground.
CAUTION
1.) Hot muffler.
You can be burned by muffler. Do not touch.

Operation Instructions
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 be filled faster than 100 seconds.
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.
