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.
