Maintenance - Homelite UT09520 Manual Del Operador

WARNING:
When servicing, use only identical Homelite replacement
parts. Use of any other parts may create a hazard or cause
product damage.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1, along with hearing protection.
Failure to do so could result in objects being thrown into
your eyes and other possible serious injuries.
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, lubricant, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating lubricants, etc., come in con-
tact with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal injury.
HIGH ALTITUDE ENGINE OPERATION
Please have an authorized service center adjust this engine
if it is to be run above 2000 feet. Failure to do so may result
in poor engine performance, spark plug fouling, hard start-
ing, and increased emissions. Carburetor adjustment by
an authorized service center will improve performance and
allow that this engine meets EPA (Environmental Protection
Agency) and California ARB (Air Resources Board) emis-
sion standards. An engine adjusted for high altitudes can
not be run at 2000 feet or lower. In doing so, the engine will
overheat and cause serious engine damage. Please have
an authorized service center restore high altitude modified
engines to the original factory specification before operating
below 2000 feet.
You can often make adjustments and repairs described here.
For other repairs, have the blower serviced an Authorized
Service Center.

MAINTENANCE

SPARK PLUG
This engine uses a Champion RCJ6Y or equivalent spark
plug with .025 in. electrode gap. Use an exact replacement
and replace annually, or more frequently if necessary.
Be careful not to cross-thread the spark plug. Cross-
threading will seriously damage the product.
CLEANING THE EXHAUST PORT, MUFFLER
AND SPARK ARRESTOR
Depending on the type of fuel used, the type and amount
of lubricant used, and/or your operating conditions, the
exhaust port, muffler, and/or spark arrestor screen may be-
come blocked with carbon deposits. If you notice a power
loss with your gas powered tool, you may need to remove
these deposits to restore performance. We highly recom-
mend that only qualified service technicians perform this
service.
The spark arrestor must be cleaned or replaced every 50
hours or yearly to ensure proper performance of your prod-
uct. Spark arrestors may be in different locations depending
on the model purchased. Please contact your nearest service
dealer for the location of the spark arrestor for your model.
To avoid a fire hazard, never run the blower without the
spark arrestor in place.
