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

DAre instructed to relieve the pressure

DStop spraying for more than 10 minutes

DCheck or service any of the system equipment

DInstall or clean the spray nozzle

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.

Operation

Startup

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

DAlways 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.

DAlways observe the CAUTIONS in this section to avoid costly damage to the pressure washer.

DIf you use the Sandblaster Kit, see the Sandblaster Kit manual for detailed cleaning information.

DSee 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.
