CLEANING THE EXHAUST PORT,
MUFFLER, AND SPARK 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 authorities.
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 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:
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.
INSPECTING AND CLEANING CHAIN
BRAKE
See Figures 69 - 70.
Remove the clutch cover and clean the chain
brake components. Check wear on the brake
band and replace if worn or deformed. The band
thickness should not be less than 0.024 in., or
worn halfway through.
Always keep the chain brake mechanism clean
and lightly brush the linkage.
Always test the chain brake performance after
cleaning. Refer to
Operating Chain Brake
for
additional information.
Check the chain catcher and replace if damaged.
WARNING:
Even with daily cleaning of the mechanism, the
dependability of a chain brake to perform under
field conditions cannot be certified. Keep the
SAFE-T-TIP™ nose guard on the saw’s guide bar
and use proper cutting techniques.
