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
immediately.
NOZZLE MAINTENANCE
See Figure 22.
Excessive pump pressure (a pulsing sensation felt while pull-
ing 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.
 To free any foreign materials clogging or restricting the
nozzle, blow out or remove debris with a straightened
paperclip 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.
CLEANING/REPLACING 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.
 Using a damp cloth, wipe the air filter cover and inner
surface. Take care not to allow dust to enter the carburetor.
 Remove the air filter.
 Rinse filter with clean water.
 Gently squeeze filter until excess water is removed.
 Apply a light coat of engine lubricant to the filter, then
squeeze it out.
