MAINTENANCE

When performing maintenance, you

may be exposed to hot surfaces, water pressure, or moving parts that can cause serious injury or death!

Before performing any maintenance or repair, disconnect spark plug wire, let engine cool and release all water pressure. The engine contains flammable fuel. DO NOT smoke or work near open flames while performing maintenance.

To ensure efficient operation and longer life of your pressure washer, a routine maintenance schedule should be prepared and followed. If the pressure washer is used in unusual conditions, such as high- temperatures or dusty conditions, more frequent maintenance checks will be required.

ENGINE

Consult the Engine Owners Manual for the manufacturer's recommendations for any and all maintenance. NOTE: The frame is equipped with an oil drain hole to help make changing the engine oil easier.

PUMP

The oil in the high pressure pump was designed to last the life of the pump. If there is a problem with the pump contact an Authorized Service Center.

NOZZLE CLEANING

If the nozzle becomes clogged with foreign materials, such as dirt, excessive pressure may develop. If the nozzle becomes partially clogged or restricted, the pump pressure will pulsate. Clean the nozzle immediately using the nozzle kit supplied and the following instructions:

1.Shut off the pressure washer and turn off the water supply.

2.Pull trigger on gun handle to relieve any water pressure.

3.Disconnect the spray wand from the gun.

4.Remove the high-pressure nozzle from the spray wand. Remove any obstructions with the nozzle cleaning tool provided and backflush with clean water.

5.Direct water supply into spray wand to backflush loosened particles for 30 seconds.

6.Reassemble the nozzle to the wand.

7.Reconnect spray wand to gun and turn on water supply.

8.Start pressure washer and place spray wand into high pressure setting to test.
