MAINTENANCE
CHANGING THE PUMP OIL
See Figure 24.
NOTE: The pump was filled with oil at the factory.
Fill the crankcase with special Cat Pumps oil per pump
specifications listed below. Do not run pump without oil
in crankcase. Change initial fill after 50 hours of run time.
Thereafter, change oil every 3 months or 500 hour intervals.
To check oil:
 Place unit on a flat, level surface.
 The sight glass is located above the drain plug. There is
a red dot in the center of the glass.
 An oil level at the top of the red dot indicates oil is at
maximum level.
 An oil level at or below the bottom of the red dot indicates
oil is below desired level, and oil should be added.
To change oil:
 Place a container under the pressure washer.
 Loosen the pump oil cap. Remove the oil drain plug and
drain the old oil.
NOTE: Drain the oil while the pump is still warm but not
hot. Warm oil will drain quickly and more completely.
 Replace the oil drain plug. Tighten securely.
 Fill with 8.5 oz. (251 ml) of Cat Pumps Oil.
Type: ISO 68 Premium Grade High Pressure Pump Oil
Model AP31045 or Cat Pumps Part Number: 6201
 Replace pump oil cap and tighten securely.
NOTE: Consult hazardous waste management guidelines in
your area for the proper way to dispose of used oil.
CHECKING A FOULED SPARK PLUG
See Figure 25.
 Clean carbon deposits off the spark plug electrode using
a plug cleaner or wire brush.
 Check electrode gap. The gap should be .6 mm - .7 mm.
Adjust the gap, if necessary, by carefully bending the side
electrode.
Replacement spark plug: Torch E6RC (NGK BR-6HS),
Champion RL86C, or equivalent

NOZZLE MAINTENANCE

See Figure 26.
Excessive pump pressure (a pulsing sensation felt while
squeezing the trigger) may be the result of a clogged or dirty nozzle.
 Turn off the pressure washer and shut off the water
supply. Pull trigger to release water pressure.
 Remove the nozzle from the spray wand.
NOTE: Never point the spray wand at your face.
 Using a straightened paper clip or nozzle cleaning tool
(not provided), free any foreign materials clogging or
restricting the nozzle.
 Using a garden hose, flush debris out of nozzle by back
flushing (running the water through the nozzle backwards
or from the outside to the inside).
 Reconnect the nozzle to the spray wand.
 Turn on the water supply and start the engine.
LONG-TERM STORAGE OF THE PRESSURE
WASHER
See Figures 27 - 28.
Store the pressure washer with the gas tank empty by running
the pressure washer until the gas runs out. Allow 30 minutes
of "cool down" time before storing the machine. Store in a
dry, covered area where the weather can't damage it.
NOTE: Make sure the water supply is connected and turned
on when allowing the pressure washer engine to run.
It is important to store this product in a frost-free area. Always
empty water from all hoses, the pump, and the detergent
container before storing.
NOTE: Use of a fuel stabilizer and pump saver will give you
better performance and increase the life of the machine.
Trigger and auxiliary handles:
 Disconnect the spray wand from the trigger handle and
place in spray wand storage.
 Remove the auxiliary handle from the trigger handle and
reinstall in the storage position.
 Remove the nozzle holder from the trigger handle. Place
the trigger handle in the trigger handle storage location.
NOTE: The nozzle holder can now be reinstalled on the
trigger handle.
