To ensure efficient operation and longer life of your pressure washer, a routine maintenance schedule should
be prepared and followed. The following routine maintenance schedule is geared to a unit in a normal working
environment. If necessary, the schedule should be modified to suit the conditions under which your pressure
washer is used. The modifications will depend upon the hours of operation and the working environment. If the
pressure washer is in an extremely dirty and/or hostile environment, it will require a greater frequency of all
maintenance checks.
MAINTENANCE
HOW TO CLEAN THE NOZZLE
If the nozzle becomes clogged with foreign material
such as dirt, excessive pump pressure may develop
and the spray pattern will change. If a nozzle be-
comes partially clogged or restricted, the pump
pressure will pulsate. If this happens, clean the nozzle
immediately using the nozzle cleaning kit supplied with
your pressure washer. The procedure is as follows:
