Maintenance
WARNING: Risk of burning. When performing maintenance, you
may be exposed to hot surfaces, water pressure or moving parts that
can cause serious injury or death.
WARNING: Risk of fire. Always disconnect, spark plug wire, let
the engine cool and release all water pressure before performing
any maintenance or repair. 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
checkswillberequired.

(CC).
3. Remove pump oil drain plug.
4. After oil is drained, replace oil drain plug.
Tighten securely.
5. Remove pump oil plug and fill with pump oil. An oil designed spe-
cifically for pressure washers is recommended as these contain a
rust inhibitor and an anit-foaming agent. If this oil is not available,
an SAE 30W non-detergent oil may be used.
6. Replace pump oil plug and tighten securely.
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
Y
spray wand. Remove any obstructions
with the nozzle cleaning tool (Y) provided
and back flush with clean water.
