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 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 Figures 28 - 30.
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. Point nozzle in a safe direction and 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,
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.
To clean nozzles on surface cleaner:
Turn off the pressure washer and shut off the water
supply. With the surface cleaner on the ground, pull trig-
ger to release water pressure.
Disconnect surface cleaner from spray wand.
Unscrew the retaining nut and remove the nozzle from
the spray bar.
NOTE: Never point the spray bar at your face.
Using the nozzle cleaning tool, 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).
Reinsert the nozzle into the spray bar, being careful not
to damage the o-ring.
NOTE: Make sure the flats of the nozzle are aligned with
the flats in the spray bar openings and the groove in the
nozzle is in the same orientation as the spray bar itself
as shown.
Reinstall the retaining nut and torque to 6-7.5 ft.lbs.
(8-10 Nm) to secure.
Reconnect the surface cleaner to the spray wand.
Turn on the water supply and start the pressure washer.
CLEANING THE AIR FILTER
See Figure 31.
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.
Rotate air filter knob counter-clockwise to open air filter
cover.
Lift the edge of the air filter carefully and pull it out.
Lightly tap or blow out dirt particles from filter.
Reinstall the air filter and cover.
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.
CHANGING ENGINE LUBRICANT
See Figure 32.
Shut off the engine.
Clean the area around the lubricant fill cap/dipstick, then
remove the lubricant fill cap/dipstick.
Tilt unit and drain.
Drain lubricant into approved container.
NOTE: Drain the lubricant while the engine is still warm
but not hot. Warm lubricant will drain quickly and more
completely.
After the crankcase is completely drained, return the
pressure washer to an upright position.
Fill with lubricant following the instructions in Adding
Lubricant To The Engine earlier in this manual.
NOTE: Used lubricant should be disposed of at an approved
disposal site. See your local oil retailer for more information.
PUMP LUBRICATION
The pump on this product was lubricated with a sufficient
amount of high grade lubricant for the life of the unit under
normal operating conditions. Therefore, no further lubrica-
tion is required.
STORING THE PRESSURE WASHER
See Figure 33.
Store the pressure washer with the gas tank empty by either
draining the tank or running the pressure washer until the
gas runs out. Allow 30 minutes of “cool down” time before
storing the machine. Store in a dry, covered area where the
weather can’t damage it.
It is important to store this product in a frost-free area. Always
empty water from all hoses and the pump before storing.
