MAINTENANCE
CHANGING ENGINE LUBRICANT
See Figure 24.

Shut off the engine.
 Clean the area around the oil cap/dipstick, then remove
the oil cap/dipstick.
 Tilt the pressure washer on its side as shown. 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.
 Replace the lubricant with new, clean lubricant (SAE 30 or
SAE 10W30). Approximately, 10 -16 oz is required. Add
engine lubricant until lubricant level is within the hatched
area on the dipstick.
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.
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. See the Replacement Parts List for
available sizes and part numbers of these items and call
customer service to order.
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, the pump, and the detergent
bucket 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 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 strongly recommended
after each use and before storing to prevent cold weather
and seal damage during storage.
 Drain the lubricant and replace with fresh, clean lubricant
as described in
Changing Engine Lubricant earlier in
this 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 cord 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.
 Extend the recoil starter rope to check its condition. If
the rope is frayed, have it replaced immediately by an
authorized service center.
 Remove all hoses. Coil the hoses and store as shown.
Do not allow the hose to become kinked.
 Pull the handle release knob out and lower the handle to
the down position.
 Store the unit and accessories in an area that does not
reach freezing temperatures. Do not store near furnace or
other sources of heat that could dry out the pump seals.
PREPARING FOR USE AFTER STORAGE
 Pull the starter grip and rope three or four times to clean
lubricant from the combustion chamber.
 Remove spark plug from the cylinder. Wipe lubricant from
the spark plug and return it to the cylinder.
 Reconnect the spark plug wire.
 Refuel the machine as described earlier in the operator’s
manual.
