GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken or
destroy plastic which could result in serious personal
injury.
Before running the engine, perform the following pre-
operation steps:
Check that all bolts, nuts, etc., are securely tightened.
Make sure the air filter is clean.
Check both the engine lubricant level and the fuel tank
level; refill as needed.
Inspect the work area for hazards.
If there is excessive noise or vibration, stop the unit im-
mediately.
NOZZLE MAINTENANCE
See Figure 20.
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.
WARNING:
NEVER remove nozzles without first turning off the engine,
relieving the water pressure in the trigger handle, and
locking the lock out on the trigger handle. NEVER point
the nozzle at your face or at others. The quick-connect
feature contains small springs that could eject the nozzle
with some force. Failure to follow these instructions could
result in an eye injury or other serious personal injury.
To free any foreign materials clogging or restricting the
nozzle, blow out or remove debris with a straightened
paper clip or fine needle.
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.
CHANGING THE PUMP LUBRICANT
See Figure 21.
NOTE:
The pump was filled with lubricant at the factory.
Fill the crankcase with SAE 15W-40 automotive grade lubri-
cant per pump specifications listed below.
Do not run pump
without lubricant in crankcase.
Change initial fill after 50
hours of run time. Thereafter, change oil every 3 months or
300 hour intervals.
To check oil:
Place pressure washer 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.
A lubricant level at the top of the red dot indicates lubri-
cant is at maximum level.
A lubricant level at or below the bottom of the red dot
indicates lubricant is below desired level, and lubricant
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 lubricant.
NOTE:
Drain the lubricant while the pump is still warm
but not hot. Warm lubricant will drain quickly and more
completely.
WARNING:
Do not change pump lubricant while it is hot. Accidental
contact with hot pump lubricant could result in serious
burns.
Replace the oil drain plug. Tighten securely.
Remove the pump oil cap.
Fill with 5 oz. (150 ml) of pump lubricant. Type: SAE 15W-40
automotive grade lubricant.
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.
PUMP MAINTENANCE
Routinely make a visual inspection of the pump. If you notice
any leaking of lubricant around the pump oil seals, take the
pressure washer to an authorized service center for repair.
If you notice excessive water leaks or low operating pres-
sure, the water seals may need to be replaced. We recom-
mend taking your pressure washer to a qualified service
center for repair, as service performed by inexperienced or
unqualified persons may damage the pressure washer and
void your warranty.
