See Figure 13.
WARNING:
To avoid serious personal injury, always turn your
saw off and allow it to cool before you clean or do any
maintenance on it.
After extended periods of use carbon deposit will build up in
the exhaust port of the muffler, causing it to become clogged.
If this situation occurs, periodically remove the carbon build
up with a slotted screwdriver. Be careful, do not damage the
muffler, piston, or cylinder.
NOTE: If an excessive amount of carbon builds up, causing
a loss of power, take your saw to an authorized service
center to be cleaned by a authorized service technician. It
may be necessary for him to remove the muffler and clean
both the muffler and cylinder.
