Pump Maintenance - Homelite UT80522G Manual Del Operador

 Fill with lubricant following the instructions in Adding/
Checking Engine Lubricant earlier in this manual.
For amount of lubricant needed to refill, see Product
Specifications earlier in this manual or the accompanying
engine manual, if applicable.
 Before using the pressure washer, check to ensure that
no lubricant is leaking from the engine.
NOTE: Consult hazardous waste management guidelines in
your area for the proper way to dispose of used lubricant.
CHECKING SPARK PLUG
See Figure 23.
 Clean the area around the base of the spark plug before
removing to keep dirt and debris out of the engine.
Remove 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. For replacement spark
plug, see Product Specifications earlier in this manual
or the accompanying engine manual, if applicable.
 Check electrode gap. The gap should be 0.7 - 0.8 mm.
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 damage
the pressure washer and void your product warranty.
STORING OF THE PRESSURE WASHER
See Figure 24.
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.
MAINTENANCE
 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 encouraged 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 hoses 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.
