CLEANING AND MAINTENANCE

Connections
Connections on pressure washer hoses, gun and spray wand should be cleaned regularly and
lubricated with non-water soluble grease.
Spray Tips Only
Clogging of the spray tips causes the pump
pressure to be too high and cleaning is
immediately required. You can clean the
spray tips by carefully inserting a needle, or
a thin, sharp instrument (i.e. paperclip) into
the tip to rid it of deposits.
Water Filter Screen
The pressure washer is equipped with two
(2) water inlet screens to protect the pump.
If the screens are not kept clean, the flow
of water to the pressure washer will be
restricted and the pump may be damaged.
1. Remove the filter screen on the water
container and the other filter screen from
the inlet adapter as shown.
2. Rinse screens until it is free of debris and
blockage.
3. Replace screens if they are damaged.
