GENERAL SAFETY RULES

DANGER

NEVER operate the pressure washer

in an enclosed area. Engine exhaust

contains carbon monoxide. Only

operate the pressure washer outside

and away from windows, doors and

vents.

WARNING

Gasoline and gasoline vapors are

extremely ﬂ ammable and explosive

under certain conditions.

• ALWAYS refuel the pressure washer outdoors, in a well-ventilated area.

• NEVER remove the fuel cap with the engine running.

• NEVER refuel the pressure washer while the engine is running. Always turn engine off and allow the pressure washer to cool before refueling.

• Only ﬁ ll fuel tank with gasoline.

• Keep sparks, open ﬂ ames or other form of ignition (such as match, cigarette, static electric source) away when refueling.

• NEVER overﬁ ll the fuel tank. Leave room for fuel to expand. Overﬁ lling the fuel tank can result in a sudden overﬂ ow of gasoline and result in spilled gasoline coming in contact with HOT surfaces. Spilled fuel can ignite. If fuel is spilled on the pressure washer, wipe up any spills immediately. Dispose of rag properly. Allow area of spilled fuel to dry before operating the pressure washer.

• Wear eye protection while refueling.

• NEVER use gasoline as a cleaning agent.

• Store any containers containing gasoline in a well-ventilated area, away from any combustibles or source of ignition.

• Check for fuel leaks after refueling. Never operate the engine if a fuel leak is discovered.

WARNING

This equipment produces a stream of water with enough high pressure to penetrate skin and its underlying tissues, which could result in amputation or other serious injury. Spray gun traps high-pressure water, even when engine is stopped and water is disconnected. Leaks caused by loose ﬁ ttings or worn or damaged hoses can result in injection injuries. DO NOT TREAT FLUID INJECTION AS A SIMPLE CUT! See a physician immediately!

• NEVER aim spray gun at people, animals or plants. Direct spray away from self and others.

• NEVER place hands in front of nozzle.

• ALWAYS point spray gun in safe direction while spraying and when relieving retained high pressure after stopping engine.

• DO NOT allow CHILDREN to operate pressure washer.

• NEVER leave spray gun unattended while machine is running.

• NEVER secure spray gun in open position.

• DO NOT twist nozzle while spraying.

• NEVER repair a high-pressure hose. ALWAYS replace it.

• NEVER repair leaking connections with sealant of any kind. ALWAYS use factory-recommended repair parts.

• NEVER hold onto the hose or ﬁ ttings during operation.

• DO NOT allow high-pressure hose to contact mufﬂ er or other extremely hot surfaces.

• ALWAYS be certain spray gun, nozzles and hoses are correctly attached and in working order.

• NEVER use spray gun if trigger lock is not in working order.

• ALWAYS use spray gun, hoses and connections rated for pressure higher than your pressure washer’s psi.

• NEVER attach or remove spray gun, nozzles or hoses while system is pressurized.

SAFETY

WARNING

• NEVER modify spray equipment.

• ALWAYS wear protective clothing to protect eyes and skin from contact with sprayed materials.

NEVER aim spray in the direction of power source. Contact with power source can cause electric shock or burn.

Unexpected kickback while spraying can cause you to fall.

• Use of pressure washer can create slippery surfaces and puddles. The operating area of this equipment should have adequate drainage to reduce the possibility of a fall due to slippery surfaces.

• Be extremely careful if necessary to use the pressure washer from a ladder, scaffolding or any other similar location.

• Use both hands to ﬁ rmly gasp the spray gun while in use to avoid injury from high-pressure kickback.

NEVER use acids, toxic or corrosive chemicals, poisons, insecticides, or any kind of ﬂ ammable solvent with this equipment. Only use detergents, cleaners and degreasers recommended for use in this pressure washer.

OPERATION

BEFORE STARTING THE PRESSURE WASHER

Before starting the pressure washer, review Safety on page 7.

Location Selection – Before starting the pressure

washer, avoid exhaust and location hazards by verifying the following:

 You have selected a location to operate the pressure

washer that is outdoors and well ventilated.

 You have selected a location with adequate drainage

but still level enough to prevent the pressure washer from tipping over.

 You have selected a location that is at least 5 feet

(1.5 m) away from any building, other equipment or combustible material.

 If the pressure washer is located close to a building,

make sure it is not located near any windows, doors and/or vents.

WARNING

Always operate the pressure washer on a surface that will prevent the pressure washer from tipping over. Placing the pressure washer on a surface that may allow the pressure washer to tip over, could cause fuel and oil to spill. Spilled fuel can ignite if it comes in contact with an ignition source such as a very hot surface.

NOTICE

Operating the pressure washer on a surface with loose material such as sand or grass clippings can cause debris to be ingested by the pressure washer that could:

• Block cooling vents

• Block air intake system

Check the following items before starting the engine:

1. Verify the pressure washer is properly assembled.

2. Check that recommended engine oil has been added to proper level in the engine crankcase.

3. Add recommended fuel to fuel tank.

4. Check for properly tightened hose connections.

5. Check to make sure there are no kinks, cuts or damage to high-pressure hose.

6. Provide a proper water supply at an adequate ﬂ ow.

ADDING / CHECKING ENGINE FLUIDS AND FUEL

Before adding/checking engine ﬂ uids and fuel, review Safety on page 7.

DANGER

Filling the fuel tank with gasoline while the pressure washer is running can cause gasoline to leak and come in contact with hot surfaces that can ignite the gasoline.

Before starting the pressure washer, always check the level of:

 Engine oil  Gasoline in the fuel tank

Once the pressure washer is started and the engine gets warm, it is not safe to add gasoline to the fuel tank or engine oil to the engine while the engine is running or the engine and mufﬂ er are hot.

Checking and / or Adding Engine Oil

WARNING

Internal pressure can build in the engine crankcase while the engine is running. Removing the oil ﬁ ll plug/ dipstick while the engine is hot can cause extremely hot oil to spray out of the crankcase and can severely burn skin. Allow engine oil to cool for several minutes before removing the oil ﬁ ll plug/dipstick.

The unit as shipped does not contain oil in the engine. You must add engine oil before starting the pressure washer for the ﬁ rst time. Use the entire supplied 0.6-liter container of engine oil. See Checking Engine Oil on page 37 and Adding Engine Oil on page 38 for instructions on checking engine oil level and the procedure for adding engine oil.

NOTICE

The pressure washer does not contain engine oil as shipped. Attempting to start the engine without adding engine oil can permanently damage internal engine components.

OPERATION

Adding Gasoline to the Fuel Tank

WARNING

Never refuel the pressure washer while the engine is running.

Always turn the engine off and allow the pressure washer to cool before refueling.

Required Gasoline – Only use gasoline that meets the

following requirements:

 Unleaded gasoline only  Gasoline with maximum 10% ethanol added  Gasoline with an 87 octane rating or higher

Filling the Fuel Tank – Follow the steps below to ﬁ ll the fuel tank:

1. Shut off the pressure washer.

2. Allow the pressure washer to cool down so all surface areas of the mufﬂ er and engine are cool to the touch.

3. Move the pressure washer to a ﬂ at surface.

4. Clean area around the fuel cap.

5. Remove the fuel cap by rotating counterclockwise.

6. Slowly add gasoline into the fuel tank. Be very careful not to overﬁ ll the tank. The gasoline level should NOT be higher than the bottom of the ﬁ ller neck.

CONNECTING THE WATER SUPPLY

NOTICE

Do not start the engine without the water supply connected and turned on. Running the pump without water will damage the pump.

Water supply must deliver a minimum of 3.8 gal (14.3 L) per minute and at least 30 psi (2 bar). Do not siphon standing water for the water supply. Water temperature must not exceed 100°F (37.7°C).

1. Run water through your garden hose to clear out any debris that may have been in the hose.

2. Inspect the water inlet screen to make sure it is in place and free of debris (see Figure 31). Do not operate the pressure washer with a missing or damaged inlet screen.

NOTICE

Take care when installing the fuel cap. Threads can be damaged if cap is incorrectly installed.

7. Install the fuel cap by rotating clockwise until you hear a click, indicating the cap is completely installed.

CAUTION

STARTING THE PRESSURE WASHER – WP2500 AND WP2800

Before starting the pressure washer, review Safety on page 7.

Before attempting to start the pressure washer, verify the following:

 The engine is ﬁ lled with engine oil (see Checking

Engine Oil on page 37).

 The pressure washer is situated in a proper location

(see Location Selection on page 26).

DANGER

Never operate the pressure washer in an enclosed area. Engine exhaust contains carbon monoxide that can kill in minutes. Only operate the pressure washer outside and away from windows, doors and vents.

1. Flip the trigger lock lever up and lock the trigger in

the OFF position (see Figure 33).

Figure 33 – Trigger Lock Lever

2. Make sure the water supply is turned on.

OTE: N The pump is equipped a with a thermo valve

(see Figure 34 and Figure 35). If the pump is run for an extended period of time without water ﬂ owing through it, it could overheat. If the pump gets to a certain temperature, the thermo valve will open and discharge warm water out the valve to allow cold water in to cool the pump.

3. Point the thermo valve away from the work area you are washing to avoid being sprayed with warm water.
