WARNING:
When servicing, use only identical replacement parts.
Use of any other parts could create a hazard or cause
product damage.
WARNING:
Always wear eye protection with side shields 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 machine, shut
off engine, wait for all moving parts to stop, and discon-
nect 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 can 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 im-
mediately.
MAINTENANCE
NOZZLE MAINTENANCE
See Figure 17.
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.
CLEANING THE AIR FILTER
See Figure 18.
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.
Unscrew air filter knob, 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.
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.
CHECKING SPARK PLUG
See Figure 19.
Clean the area around the base of the spark plug before
removing to keep dirt and debris out of the engine. Re-
move spark plug.
Clean off carbon deposits on the spark plug electrode us-
ing a plug cleaner or wire brush. Replace the plug if worn.
For replacement spark plug, see Product Specifications
earlier in this manual or the accompanying engine manual,
if applicable.
Check electrode gap. The gap should be .03 in. (0.7- 0.8 mm).
Adjust the gap, if necessary, by carefully bending the
ground electrode.
Reinstall spark plug. Tighten securely.
