Check electrode gap. The gap should be .028 in. - .031 in.
(0.70- 0.80 mm). Adjust the gap, if necessary, by carefully
bending the ground electrode.
Reinstall spark plug. Tighten securely.
CHANGING ENGINE LUBRICANT
See Figure 21.
Shut off the engine.
Clean the area around the lubricant drain plug, then re-
move the plug.
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.
Replace the lubricant drain plug.
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 MAINTENANCE
Routinely make a visual inspection of the pump. If you notice
any leaking of lubricant around the pump seals, take the
pressure washer to an authorized 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 22.
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 fuel valve is in the OFF position.
Disconnect the water connection.
Empty the pump by pulling on the recoil starter 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 during storage to prevent cold weather
damage during storage over the winter months.
Drain the lubricant and replace with fresh, clean lubricant
as described in
Adding/Checking Engine Lubricant in
the Operation section of 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.
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 recoil starter grip 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.
