MAINTENANCE
CLEANING THE AIR FILTER
See Figure 20.
A dirty air filter will cause starting difficulty, loss of perfor-
mance, 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 tabs on the air filter cover to open, then remove
the air filter cover.
Lift the edge of the air filter carefully and pull it out.
Brush the air filter lightly to clean.
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 THE SPARK PLUG
See Figure 21.
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
using a plug cleaner or wire brush. Replace the plug if
worn. For replacement spark plug, see
Product Specifica-
tions
earlier in this manual or the accompanying engine
manual, if applicable.
Check electrode gap. The gap should be .028 in. – .032 in.
(0.7 mm – 0.8 mm). Adjust the gap, if necessary, by care-
fully bending the ground electrode.
Reinstall spark plug. Tighten securely.
CHANGING ENGINE LUBRICANT
See Figure 22.
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.
Tilt the pressure washer on its side as shown. Drain lu-
bricant into approved container.
NOTE:
Drain the lubricant while the engine is still warm
but not hot. Warm lubricant will drain quickly and more
completely.
WARNING:
Do not change engine lubricant while it is hot. Accidental
contact with hot engine lubricant could result in serious
burns.
After the crankcase is completely drained, return the
pressure washer to an upright position.
Fill with lubricant following the instructions in
Adding/
Checking Engine Lubricant
earlier in this manual. For
amount of lubricant needed to refill, see
Product Specifi-
cations
earlier in this manual or the accompanying engine
manual, if applicable.
NOTE:
Consult hazardous waste management guidelines in
your area for the proper way to dispose of used lubricant.
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.
PUMP MAINTENANCE
Routinely make a visual inspection of the pump. If you no-
tice any leaking of lubricant around the pump seals, take
the pressure washer to a qualified service center for repair.
There are no user serviceable parts to the pressure washer
pump. Any attempt to service or alter the pump may dam-
age the pressure washer and void your product warranty.
STORING THE PRESSURE WASHER
See Figure 23.
NOTE: Regular use of fuel stabilizer and pump protector
will give you better performance of the unit and increase
the life of the pump.
WARNING:
While storing, keep at least 3 feet of clearance on all sides
of this product, including overhead. Allow a minimum of
30 minutes of “cool down” time before storage. Heat cre-
ated by muffler and exhaust gases could be hot enough
to ignite combustible objects.
Store in a dry, covered area where the weather can’t dam-
age it.
It is important to store this product in a frost-free area. Always
empty water from all hoses, the pump, and the soap tank
before storing.
Drain the fuel tank completely by running the pressure
washer until the gas runs out. Stored gas can go stale in
30 days.
NOTE:
Make sure the water supply is connected and
turned on when allowing the pressure washer engine to
run.
Make sure the on/off switch and fuel valve are in the OFF
position.
Disconnect both the high pressure hose and the garden
hose from the pump.
Empty the pump by pulling on the starter grip and rope
about 6 times. This should remove most of the liquid from
the pump.
