Pump Maintenance; Storing The Pressure Washer - Homelite UT80522A Manuel D'utilisation

CHECKING SPARK PLUG
See Figure 20.
 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 or reuse is questionable. (Recommended spark
plug: Champion RC12YC).
 Check electrode gap. The gap should be 0.7 - 0.8 mm
in. Adjust the gap, if necessary, by carefully bending the
ground electrode.
 Check the condition of the spark plug gasket.
 Reinstall spark plug. Start the spark plug in its threads
by hand and finger-tighten.
 Tighten with wrench to compress washer. If spark plug
is new, use 1/2 turn to compress washer appropriate
amount. If reusing old spark plug, use 1/8 to 1/4 turn for
proper washer compression.
NOTE: An improperly tightened spark plug will become
very hot and could damage the engine.

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 21.
Store the pressure washer with the gas tank empty by either
draining the tank or running the pressure washer until the
gas runs out.
NOTE: If running pressure washer until gas runs out, make
sure machine is connected to water and water is ON.
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.
Discharge Fuel:
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.
Engine Lubricant:
Drain the lubricant and replace with fresh, clean lubricant
as described in Adding/Checking Engine Lubricant in the
Operation section of this manual.

Spark Plug:
 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.
Air Filter:
Clean the air filter.
Recoil Starter Rope:
Extend the recoil starter rope to check its condition. If the
rope is frayed, have it replaced immediately by an authorized
service center.
Hoses and Pump:
Flush the detergent injection hose with clean water for 1-2
minutes. Remove all hoses. Empty the pump by pulling on
the recoil starter about 6 times. This should remove most of
the liquid from the pump.
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 at 1-800-242-4672 to order.
For winterizing and long-term storage:
 Disconnect the water connection.
 Disconnect the spark plug wire from the engine.
 Pull recoil rope and jump engine several times to eliminate
any water remaining in the pump.
 Coil the hoses and place in the hook-and loop strap on the
unit's handle. 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.
CAUTION:
The use of a pump protector is recommended to prevent
cold weather damage during storage over the winter
months.
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.
