WARNING: Burn hazard

Never open oil port while engine is running. Hot oil can spray over face and body.

Notes: o Low oil shutdown feature prevents the engine from starting without sufficient

oil.

o Engine is shipped without

oil. You must add oil before first use.

Inspect spray system

Always inspect spray system for damage and leaks before each use. Do not start pressure washer until all needed repairs have been completed.

WARNING: High pressure fluid injection hazard

High-pressure fluid discharge from leaks (even pin-sized) or ruptured components can pierce skin and inject fluid into the body. Injection injury can result in blood poisoning and/or severe tissue damage leading to infection, gangrene, and possibly amputation.

• Never use a finger or skin to check for leaks.

• Never operate machine with damaged or missing hoses/parts.

• Never attempt to repair a high-pressure hose or component – Always

replace it with a part that is rated at or above the pressure rating of this machine.

Before Each Use

1) Check hoses, fittings, wand, trigger gun and connections for signs of wear, cracks, looseness, or leaks. Replace as required.

2) Check and clean the nozzle orifice.

3) Clean inlet filter. (See Maintenance instructions)

Inspect fuel system

Perform other scheduled maintenance as needed

Always inspect (engine and burner) fuel systems & check for leaks BEFORE starting pressure washer. Do not start pressure washer until all needed repairs have been completed.

WARNING: Fuel leak hazard

Gasoline and burner fuels are highly explosive and fuel leaks can result in fire or explosions. You can be burned and seriously injured if the fuel system is not properly hooked up or there is a fuel leak when you start the engine.

Inspect the entire fuel system. Look for:

• signs of leaks or deterioration,

• chafed or spongy fuel hose,

• loose connections,

• loose or missing fuel hose clamps,

• damaged gasoline tank, or

• defective gasoline shut-off valve.

Make sure that any other regular maintenance has been performed as prescribed in this manual in the “Maintenance & Repair” section.

1. Refer to the engine owner’s manual for engine maintenance instructions.

2. Make sure battery is charged. Charge as needed according to your battery manufacturer’s instructions.

Step 2. Add Fuel(s)

WARNING: Fuel fire/explosion hazard

Gasoline is highly flammable and explosive. Burner fuels are combustible at warm temperatures. Heat, sparks, and flames can ignite fuel vapors, which can become widespread during fueling. A flash fire and/or explosion could result and cause serious injury or death. Always use extreme care when handling fuels. Carefully follow all instructions to avoid the following conditions which could result in fuel ignition:

• gas vapor collection inside enclosures

• static electric sparks

• sparks from electric wiring, batteries, or running engines

• sources of heat (such as a hot engine, burner or exhaust)

• open flames, including pilot lights

Always follow these general safety rules when fueling:

1) Turn pressure washer off and allow to cool for at least two minutes before removing any fuel cap. Note: A running or still-hot engine or burner is hot enough to ignite fuel.

Before Each Use

2) Fill fuel tank OUTDOORS – never indoors. Fuel vapors can ignite if they collect inside an

enclosure and explosion can result.

3) Stay away from all sources of heat, sparks, and flames. Do not smoke.

4) Never pump fuel directly into the gas tank or burner at a gas station – it could cause a static

electric spark. Follow these steps to avoid static electric sparking during fueling:

• Use an approved portable container to transfer fuel to the pressure washer’s

tank. (A portable container made of metal or conductive plastic is preferred because it dissipates charge to ground more readily.)

• Always place container on the ground to be filled. Never fill the portable gas

container while it is sitting inside a vehicle, trailer, trunk, or pick-up truck bed.

• Dissipate static charge from your body before beginning the fueling process

by touching a grounded metal object at a safe distance from fuel sources.

• Keep nozzle in contact with container while filling. Do not use a nozzle lock-

5) Clean up fuel spills /splashes immediately.

open device.

• If possible, move the pressure washer away from spilled fuel on the ground.

• Wipe up spilled fuel and wait 5 minutes for excess fuel to evaporate before starting

engine.

• Fuel soaked rags are flammable and should be disposed of properly.

• If fuel is spilled on your skin or clothes, change clothes and wash skin immediately.

Fill engine fuel tank

Fill burner fuel tank

(if planning to use heated water)

Check the gasoline tank level. If needed, fill tank with fresh unleaded gasoline from a portable container:

1) Remove engine gas cap.

2) Add gasoline through the fill opening:

- Use only an UL-approved portable gasoline container to transfer the gasoline to engine’s tank.

- Do NOT overfill the gasoline tank. Allow at least 1/2” of empty space below the fill neck to allow for fuel expansion.

3) Replace gas cap securely before starting engine.

4) Store extra gasoline in a cool, dry place in an UL-approved, tightly sealed container.

If you are planning to use heated water, fill burner fuel tank with #1 or #2 diesel, B5 or lower biodiesel, kerosene, or fuel oil.

1) Remove burner fuel cap.

2) Add fuel through the fill opening. Do not overfill. Allow at least 1/2” of empty space below fill neck to allow for fuel expansion.

3) Replace fuel cap securely before starting engine.
