Caution Symbol

CAUTION

This symbol alerts you to the possibility of damage to or destruction of equipment if you do not follow the instructions.

D Fluid injected into the skin may look like just a cut, but it is a serious injury. Get emergency

medical attention.

D Do not point the gun at anyone or at any part of the body.

D Do not stop or deflect leaks with hand, body, glove, or rag.

D Do not put your hand or fingers over the spray tip.

D Tighten fluid connections before you start this equipment.

D Engage the gun trigger safety when you stop spraying.

D Follow Pressure Relief Procedure on page 5 if the spray tip clogs and before you clean,

check, or service this equipment.

D Repair or replace worn or damaged parts immediately.

D Check hoses, tubes, and couplings daily. Do not repair high-pressure couplings; you must replace

the entire hose. Fluid hoses must have spring guards on both ends to prevent kinks and rupture.

WARNING

MOVING PARTS HAZARD

Moving parts, such as the drive belt, can pinch or amputate fingers.

D Keep clear of moving parts when you start or operate this equipment.

D Do not operate the pressure washer without all guards and interlocks installed and functioning.

HAZARDOUS FLUIDS

Improper handling of hazardous fluids can cause serious injury or death from splashing in the eyes, ingestion, or bodily contamination.

D Know the specific hazards of the fluid being used.

D Store hazardous fluids in approved containers. Dispose of hazardous fluids per local, state, and

national guidelines.

D Wear protective eye wear, gloves, clothing, and respirator as recommended by the fluid and

solvent manufacturer.

FUEL HAZARD

The fuel used in this pressure washer is combustible. When spilled on a hot surface, it can ignite and cause a fire.

Do not fill the fuel tank while the engine is running or hot.

EXHAUST HAZARD

The exhaust contains poisonous carbon monoxide, which is colorless and odorless. Do not operate this equipment in a closed building.

EQUIPMENT MISUSE HAZARD

Misuse of the pressure washer or accessories may cause them to rupture and result in fluid injection, splashing in the eyes or on the skin, or other serious injury.

D Do not alter or modify any part or factory-set adjustment of this equipment.

D Do not exceed the maximum working pressure of any component or accessory in the system.

D Do not use any chemicals that are incompatible with the wetted parts as stated in the Technical

Data on page 15.

D Do not alter the throttle setting.

Check for Shipping Damage

Check the pressure washer for shipping damage. If anything is damaged, notify the carrier immediately.

Set Up

Connect the high-pressure hose between the pump outlet and the gun inlet. Both of these connections are made with quick couplers.

CAUTION

Up to 100 ft (30 m) of high-pressure hose may be used. Longer hoses may affect sprayer and chemical injector performance.

Connect to Water Supply

CAUTION

Before you connect to the water supply, check your local plumbing code regarding cross connection to the water supply. Backflow Preventer 801133 is available to prevent backflow of contaminated water into the fresh water supply. Install it upstream from the pump.

If inlet water pressure is over 60 psi (414 kPa,

4.1 bar) Regulating Water Valve 800258 must be installed at the garden hose connection.

Do not exceed 160_ F (70_ C) inlet water temperature.

Install the appropriate spray tip on the wand. See Installing and Changing Spray Tips on page 6. If you use a sandblaster kit, see its separate manual for installation instructions.

4 308524

Connect a hose with at least a 3/4-in. (19 mm) ID from the water supply to the 3/4-in. garden hose inlet. The supply hose should not be more than 50 ft (15 m) long

NOTE: The water source must have a minimum flow rate equal to that of the pressure washer. See

Technical Data on page 15.

Pressure Relief Procedure

WARNING

INJECTION HAZARD

The system pressure must be manually relieved to prevent the system from

spraying accidentally. To reduce the risk of an injury from accidental spray from the gun, splashing fluid, or moving parts, follow the Pressure Relief Procedure when you

D Are instructed to relieve the pressure D Stop spraying for more than 10 minutes D Check or service any of the system equipment D Install or clean the spray nozzle

Operation

Startup

1. Engage the trigger safety latch.

2. Turn off the pressure washer, and remove the ignition cable from the spark plug.

3. Shut off the water supply.

4. Disengage the trigger safety latch, trigger the gun to relieve the pressure, and engage the trigger safety latch.

If you suspect that the spray tip or hose is clogged or that pressure has not been fully relieved after following the steps above: Disengage the trigger safety latch,

and trigger the gun to relieve pressure. Wrap a rag around the hose end coupling, and VERY SLOWLY loosen the coupling to relieve pressure gradually. Then loosen it completely. Then clear the tip or hose.

Always use this startup procedure to ensure that the pressure washer is started safely and properly.

D Always engage the gun trigger safety latch when

you stop spraying even for a moment. This reduces the risk of fluid injection or splashing in the eyes or on the skin if the gun is bumped or triggered accidentally.

D Always observe the CAUTIONS in this section to

avoid costly damage to the pressure washer.

D If you use the Sandblaster Kit, see the Sandblaster

Kit manual for detailed cleaning information.

D See manual 308513 for chemical injector operation

and service.

1. Check the oil level.

NOTE: This pressure washer is equipped with a low-oil sensor that shuts the engine off if the oil level falls below a certain level. If the engine stops unexpectedly, check the oil and the fuel levels. Check the oil level each time you refuel.

2. Check the fuel level.

WARNING

FIRE HAZARD

Do not refuel a hot engine. Refueling a

hot engine could cause a fire. Use only fresh, clean, regular or unleaded gasoline. Close the fuel shutoff valve during refueling.

3. Turn on the water supply.

CAUTION

Never run the pressure washer dry. Costly damage to the pump will result. Always be sure the water supply is completely turned on before you run the pressure washer.

4. Trigger the gun until water sprays from the tip indicating that the air is purged from the system.

5. Open the fuel shutoff valve. Be sure the spark plug ignition cable is pushed firmly onto the spark plug. Put the engine switch in the ON position, and put the throttle in the RUN position.

CAUTION

Do not allow the pressure washer to idle for more than 10 minutes. Doing so may cause the recirculating water to overheat and seriously damage the pump. Turn off the pressure washer if it will not be spraying or cleaning at least every 10 minutes. If heated inlet water is used, reduce this time further. Do not operate the pressure washer with the inlet water screen removed. This screen helps keep abrasive sediment, which could clog the pump or damage the pump cylinders, out of the pump. Keep this screen clean. Do not pump caustic materials; such materials could corrode the pump components.
