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.
