ARRESTOR
NOTICE:
This product is equipped with a spark arrestor
that has been evaluated by the USDA Forest
Service; however, product users must comply
with Federal, State, and local fire prevention
regulations. Check with appropriate authori-
ties. Contact customer service or a qualified
service center to purchase a replacement 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 replaced every 50 hours
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:
Never run the chain saw without a muffler
equipped with a spark arrestor in place. Failure
to do so could result in a fire that could cause
serious personal injury.
