CLEAN ENGINE
COOLING RNS
For best performance, keep dirt from accumulating
around the engine cooling fins. Clogged cooling fins
cause the engine to run hotter and shorten engine life.
Cooling fins may be cleaned using a toothbrush or stiff
bdstle brush.

CHAIN
TENSION
Correct chain tension is very important to insure a long
service life for the chain. Check the chain tension each
time the saw is stopped and the bar and chain have
cooled off. Check the tension and the chain and bar
lubdcation frequently during prolonged pedods of
cutting. If the chain is loose, lubricate it well and let it
cool off before readjusting the tension.
WARNING: Be sure the chain is properly tensioned. A
sagging chain can jump out of the bar groove, break,
and cause sedous injury,
The chain tension needs adjusting if the chain is
sagging away from the underside of the bar when the
saw is held updght (Fig. 29).
