MAINTENANCE
CLEANING THE EXHAUST PORT, MUFFLER AND SPARK ARRESTOR
NOTICE:
The spark arrestor on this product has not been evaluated by the USDA Forest Service and cannot
be used on U.S. forest lands. In addition, product users must comply with Federal, State, and local
fire prevention regulations. Check with appropriate authorities. Contact Customer Service or your
authorized service center to purchase a replacement spark arrestor.
If the trimmer appears less efficient or powerful, it may be due to the build-up of carbon deposits
around the exhaust port and muffler. This may occur depending on the type of fuel used, the type and
amount of lubricant used, or the operating conditions. In order to restore performance, take the trimmer
to an authorized service center or qualified individual to remove the blockage.
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.
IDLE SPEED ADJUSTMENT
WARNING
The trimmer head will move when adjusting the idle speed. Wear protective clothing and keep all
bystanders, children, and pets at least 50 ft. (15 m) away. Keep the trimmer off the ground and away
from any objects when making adjustments. Keep all parts of your body away from the trimmer head
and muffler. Failure to follow these instructions could result in serious personal injury.
The cutting attachment should never turn at idle. If the cutting attachment moves at idle speed,
discontinue use immediately and contact an authorized service center to have the tool repaired.
Serious personal injury could result from the cutting attachment turning at idle.
