Cylinder Cooling Fins
Maintenance Interval
・
The cylinder cooling fins should be cleaned after every 25 hours of operation, or one a week, or once a
week, whichever comes first.
・
Air must flow freely around and through the cylinder cooling fins to prevent engine overheating.
Leaves, grass, dirt and debris build-up on the fins will increase the operating temperature of the engine,
which can reduce engine performance and shorten engine life.
Cooling Fin Cleaning
1. Loosen the knob and remove the filter cover.
2. Twist the high tension lead boot on the spark plug
back and forth a couple of times to loosen the boot,
then pull the boot off of the spark plug.
3. Loosen the knob and lift off the cylinder cover.
4. Clean all dirt and debris from the cooling fins and
from around the cylinder base.
5. After cleaning, reinstall the cylinder cover, high ten-
sion lead boot and the filter cover.
