MAINTENANCE
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.
CLEANING THE AIR fILTER
See Figures 6 - 7.
For proper performance and long life, keep air filter clean.

Remove the air filter cover by turning the dial counter
clockwise while gently pulling on the cover.
 Rinse filter with clean water.
 Gently squeeze filter until excess water is removed.
Replace filter.
 Place the air filter cover back on the unit. Turn dial
clockwise until cover is secure.
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.
wARNING:
Be careful not to cross-thread the spark plug. Cross-
threading will seriously damage the product.
CLEANING THE EXHAUST PORT, MUffLER
AND SPARK ARRESTOR
NOTE: 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
become 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
recommend 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
product. 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.
wARNING:
To avoid a fire hazard, never run the blower without the
spark arrestor in place.
