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.

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

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.

WARNING:

To avoid a fire hazard, never run the blower without the spark arrestor in place.
