NOTICE:
Periodically inspect the entire product for damaged,
missing, or loose parts such as screws, nuts, bolts, caps,
etc. Tighten securely all fasteners and caps and do not
operate this product until all missing or damaged parts are
replaced. Please contact customer service or a qualified
service center for assistance.
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 18.
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.
MAINTENANCE
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.
CLEANING/REPLACING THE AIR FILTER
See Figure 19.
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 20.
Clean the area around the base of the spark plug before
removing to keep dirt and debris out of the engine.
Remove spark plug.
Clean off carbon deposits on the spark plug electrode
using a plug cleaner or wire brush. Replace the plug if
worn or reuse is questionable. 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 .028 in.-.032 in.
(0.7- 0.8 mm). Adjust the gap, if necessary, by carefully
bending the ground electrode.
Reinstall spark plug. Tighten securely.
CHANGING ENGINE LUBRICANT
See Figure 21.
Shut off the engine.
Clean the area around the oil fill cap/dipstick, then remove
the oil fill cap/dipstick.
NOTE: Remove the dipstick to allow lubricant to drain
easier and more quickly.
Disconnect the spark plug wire from the engine.
