General Maintenance; Nozzle Maintenance; Maintenance - Homelite UT80522G Manual Del Operador

WARNING:
When servicing, use only identical replacement parts.
Use of any other parts could create a hazard or cause
product damage.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1. Failure to do so could result in
objects being thrown into your eyes resulting in possible
serious injury.
WARNING:
Before inspecting, cleaning or servicing the machine,
shut off engine, wait for all moving parts to stop, and
disconnect spark plug wire and move it away from spark
plug. Failure to follow these instructions can result in serious personal injury or property damage.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken or
destroy plastic which could result in serious personal injury.
Only the parts shown on the parts list are intended to be
repaired or replaced by the customer. All other parts should
be replaced at an authorized service center.
Before running the engine, perform the following pre-
operation steps:
 Check that all bolts, nuts, etc., are securely tightened.
 Make sure the air filter is clean.
 Check both the engine lubricant level and the fuel tank
level; refill as needed.
 Inspect the work area for hazards.
 If there is excessive noise or vibration, stop the unit
immediately.

NOZZLE MAINTENANCE

See Figure 20.
Excessive pump pressure (a pulsing sensation felt while
pulling the trigger) may be the result of a clogged or dirty
nozzle.

MAINTENANCE

 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.
 Using a straightened paper clip or nozzle cleaning tool
(not provided), free any foreign materials clogging or
restricting the nozzle.
 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 21.
A dirty air filter will cause starting difficulty, loss of performance,
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
carburetor.
 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.
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.
 Reinstall the filter cover.
CHANGING ENGINE LUBRICANT
See Figure 22.
 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
container.
NOTE: Remove the dipstick to allow lubricant to drain
easier and more quickly.
NOTE: Consult hazardous waste management guidelines
in your area for the proper way to dispose of used
lubricant.
