MAINTENANCE
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 21.
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 en-
gine, 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 in-
structions 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 (not included).
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/Replacing the Air Filter
See Figure 22.
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 paper air filter
at least once a year.
Remove the wing nut from the air cleaner cover, then
remove the cover.
Remove the wing nut from the air cleaner assembly, then
remove the air cleaner assembly.
Separate the foam filter from the paper filter. Inspect both
filters and replace if damaged.
To clean the paper filter, use compressed air or tap the
paper filter element several times on a hard surface to
remove dirt.
Clean the foam filter with warm soapy water. Rinse and
let dry.
Apply a light coat of engine lubricant to the foam filter
element, then squeeze it out.
Reinstall the foam filter over the paper filter.
Reinstall the air cleaner assembly, then reinstall the wing
nut to secure.
NOTE: Make sure the gasket is in place before reinstalling
the air cleaner assembly.
Using a damp cloth, wipe the inside of the air cleaner
cover. Take care not to allow dust to enter the carburetor.
Reinstall the air cleaner cover, then reinstall the wing nut
to secure.
NOTE: Do not run the pressure washer without the air cleaner
assembly in place. Rapid engine wear will result.
Changing Engine Lubricant
See Figure 23.
Shut off the engine.
Clean the area around the oil cap/dipstick, then remove
the oil cap/dipstick.
NOTE: Remove the dipstick to allow lubricant to drain
easier and more quickly.
Disconnect the spark plug wire from the engine.
To drain the lubricant, remove the drain plug from the
bottom of the engine. Drain lubricant into an approved
container, then reinstall drain plug and tighten securely.
NOTE: Drain the lubricant while the engine is still warm
but not hot. Warm lubricant will drain quickly and more
completely.
Do not change engine lubricant while it is hot. Accidental
contact with hot engine lubricant could result in serious
burns.
