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.
MAINTENANCE
 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.
