WHEN DOING MAINTENANCE, YOU MAY BE EXPOSED TO HOT SURFACES, WATER PRESSURE,
MOVING PARTS, OR FIRE RESULTING IN DEATH. BEFORE PERFORMING ANY MAINTENANCE OR

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:
ENGINE
1. Consult Engine Owner's Manual for manufacturer's
recommendations for any and all engine
maintenance.
PUMP
The DAPC pump on your pressure washer was
shipped from the factory with oil. The oil in your pump
must be changed every 50 hours thereafter.
1. Using an 5/16 inch wrench, remove drain plug
from underside of pump and drain oil into a
suitable container.
Oil Fill Cap
Oil Drain Plug
2. Replace oil drain plug and tighten securely.
3. Remove oil fill plug from top of pump.
4. Fill pump with 8 ounces of R&O 150 oil. NOTE: If
