WHEN DOING MAINTENANCE, YOU MAY BE EXPOSED TO HOT SURFACES, WATER PRESSURE,
MOVING PARTS, OR FIRE RESULTING IN DEATH. BEFORE PERFORMING ANY MAINTENANCE OR
REPAIR, DISCONNECT SPARK PLUG WIRE, LET ENGINE COOL AND RELEASE ALL WATER PRES-
SURE. 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. 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
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.
1. Run engine until it runs out of fuel. Otherwise, fuel
can leak out, creating a fire/explosion hazard,
when you tip engine.
2. Disconnect spark plug wire and keep it away from
spark plug.
3. Drain engine oil. Refer to engine owner's manual
for correct procedure.
Used oil is a hazardous waste product.
Dispose of used oil properly. Do not discard
with household waste. Check with your
local authorities for safe disposal/recycling
facilities.
4. Using a 5/16" Allen wrench remove pump oil drain
plug.
5. Tilt unit and drain pump oil into appropriate
container.
6. Fill pump with 10 ounces of R&O 150 oil. NOTE:
If unable to find R&O 150 oil, use 30W non-
detergent oil.
7. Replace oil drain plug and tighten securely.
8. Refill engine with oil and fuel. Refer to engine
owner's manual for correct procedure.
