MAINTENANCE
wARNING:
When servicing, use only identical replacement
parts. Use of any other parts may create a hazard
or cause product damage.
wARNING:
Always wear eye protection marked to comply with
ANSI Z87.1. Failure to do so could result in objects
being thrown into your eyes, resulting in possible
serious injury.
wARNING:
Before inspecting, cleaning or servicing the ma-
chine, shut off engine, wait for all moving parts to
stop, and disconnect spark plug wire and move
it away from spark plug. Failure to follow these
instructions can result in serious personal injury or
property damage.
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 may
result in serious personal injury.
Only the parts shown on the parts list are intended to be
repaired or replaced by the customer. All other parts should
be replaced at an authorized service center.
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 oil 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
immediately.
CLEANING THE AIR FILTER
See Figure 23.
A dirty air filter will cause starting difficulty, loss of
performance, and shorten the life span of the engine. Check
the air filter monthly. For best performance, replace the air
filter at least once a year.
Push the tab on the air filter cover to open, then remove
the air filter cover.
Lift the edge of the air filter carefully and pull it out.
Wash the air filter with warm, soapy water.
Rinse and squeeze to dry.
Put small amount of motor oil (SAE 30 or SAE 10W30) on
the filter sponge. Squeeze out the excess oil then reinstall
the air filter.
NOTE: Make sure the filter is seated properly inside the
cover. Installing the filter incorrectly will allow dirt to enter
the engine, causing rapid engine wear.
Reinstall the air filter cover.
CHANGING THE OIL
See Figure 24.
Place a container under the pressure washer.
Remove the oil drain plug and drain the old oil.
NOTE: Drain the oil while the engine is still warm but not
hot. Warm oil will drain quickly and more completely.
Replace
the oil drain plug.
Replace the oil with new, clean oil. This engine will hold
20 oz. or .6 liters of oil (SAE 30 or SAE 10W30).
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: NKG E6RC 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.
