Pump Maintenance - Homelite UT80546 Manual Del Operador

 Turn off the pressure washer and shut off the water
supply. Pull trigger to release water pressure.
 Remove the nozzle from the spray wand.
NOTE: Never point the spray wand at your face.
 To free any foreign materials clogging or restricting the
nozzle, blow out or remove debris with a fine needle.
 Using a garden hose, flush debris out of nozzle by back
flushing (running the water through the nozzle backwards
or from the outside to the inside).
 Reconnect the nozzle to the spray wand.
 Turn on the water supply and start the engine.
CLEANING/REPLACING THE AIR FILTER
See Figure 19.
A dirty air filter will cause starting difficulty, loss of perfor-
mance, and shorten the life span of the engine. Check the
air filter monthly. For best performance, replace the air filter
at least once a year.
The filter cover pivots up and lifts off.
 Using a damp cloth, wipe the air filter cover and inner
surface. Take care not to allow dust to enter the carbure-
tor.
 Remove the air filter.
 Rinse filter with clean water.
 Gently squeeze filter until excess water is removed.
 Apply a light coat of engine lubricant to the filter, then
squeeze it out.
 Reinstall the foam filter.
 Reinstall the filter cover.
NOTE: Make sure the filter is seated properly inside the
compartment. Installing the filter incorrectly will allow dirt
to enter the engine, causing rapid engine wear.
CHANGING ENGINE LUBRICANT
See Figure 20.
 Shut off the engine.
 Clean the area around the oil fill cap/dipstick, then remove
the oil fill cap/dipstick.
To drain lubricant from the oil drain plug:
 Disconnect the spark plug wire from the engine.
 To drain the lubricant, remove the drain plug from the
bottom of the engine. Drain lubricant into approved con-
tainer.
NOTE: Remove the dipstick to allow lubricant to drain
easier and more quickly.
 Fill with lubricant following the instructions in Adding/
Checking Engine Lubricant earlier in this manual.
 Before using the pressure washer, check to ensure that
no lubricant is leaking from the engine.
MAINTENANCE
NOTE: Used lubricant should be disposed of at an ap-
proved disposal site. See your local oil retailer for more
information.
CHECKING SPARK PLUG
See Figure 21.
 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 damage
the pressure washer and void your product warranty.
STORING THE PRESSURE WASHER
See Figure 22.
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.
NOTE: Use of a fuel stabilizer and pump saver will give you
better performance and increase the life of the machine.
Discharge Fuel:
Drain the fuel tank completely. Stored gas can go stale in
30 days.
