MAINTENANCE
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
The trimmer head will move when adjusting the idle speed. Wear all 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.
