To check pump lubricant:
 Place pressure washer on a flat, level surface.
 Unscrew the pump oil cap/dipstick by turning counter-
clockwise.
 Wipe pump oil cap/dipstick clean and re-seat in hole; do
not rethread.
 Remove pump oil cap/dipstick again and check pump lu-
bricant level. Lubricant level should fall within the hatched
area on the dipstick.
 If level is low, add pump lubricant until the fluid level rises
to the upper portion of the hatched area on the dipstick.
 Replace and secure the oil cap/dipstick.
To change pump lubricant:
 Place a container under the pressure washer.
 Loosen the pump oil cap/dipstick. Remove the oil drain
plug and drain the old pump lubricant.
NOTE: Drain the pump lubricant while the pump is still
warm but not hot. Warm lubricant will drain quickly and
more completely.
WARNING:
Do not change pump lubricant while it is hot. Accidental
contact with hot pump lubricant could result in serious
burns.
 Replace the oil drain plug. Tighten securely.
 Remove the pump oil cap/dipstick.
 Fill with 5 oz. (150 ml) of pump lubricant. Type:
SAE 15W-40 automotive grade lubricant.
 Replace pump oil cap/dipstick and tighten securely.
NOTE: Consult hazardous waste management guidelines
in your area for the proper way to dispose of used lubricant.
PUMP MAINTENANCE
Routinely make a visual inspection of the pump. If you notice
any leaking of lubricant around the pump oil seals, take the
pressure washer to an authorized service center for repair.
If you notice excessive water leaks or low operating pres-
sure, the water seals may need to be replaced. We recom-
mend taking your pressure washer to an authorized service
center for repair, as service performed by inexperienced or
unqualified persons may damage the pressure washer and
void your warranty.
MAINTENANCE
STORING THE PRESSURE WASHER
See Figure 25.
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 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.
 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 engine switch is in the OFF position and
the fuel valve is in the CLOSED position.
 Disconnect the water connection.
 Empty the pump by pulling on the starter grip and rope
about 6 times. This should remove most of the liquid from
the pump.
NOTICE:
The use of a pump protector is required after each use
and before storing to prevent cold weather and seal
damage during storage. Failure to use pump protector
will void your warranty.
 Drain the lubricant and replace with fresh, clean lubricant
as described in the engine manual.
 Disconnect spark plug wire and remove the spark plug.
Pour about a teaspoon of clean, air-cooled, four-cycle
lubricant through the spark plug hole into the combustion
chamber.
 Leaving the spark plug out, pull the starter grip and rope
two or three times to coat the inside of the cylinder wall.
 Inspect the spark plug and clean or replace, as necessary.
 Reinstall the spark plug, but leave the spark plug wire
disconnected.
 Clean the air filter.
