Preparation
Adjusting Chain Tension
m
WARNING!
Use protective gloves when handling the
bar and chain.
1. Make sure the pruning saw is off and the battery is
removed.
2. To tighten the chain, turn the tensioning wheel clockwise
until you meet some resistance. Prior to use, a cold chain
should have no slack on the underside of the guide bar,
while still allowing you to rotate the chain by hand without
binding. Be aware that a chain tensioned while warm, may
be too tight upon cooling. (Fig. 13).

Tensioning wheel
3. To check the chain tension, lightly pull the chain 1/8"
(3 mm) away from bottom of guide bar. If the chain snaps
back into place upon release, the tension is correct.
During normal operation, the chain will heat up and
expand causing the chain sag slightly by approximately
0.05 in. (~1.25 mm) (Fig. 14).
NOTE: A new chain will stretch. Check the tension of
a new chain frequently during the first two hours of
operation, after disconnecting the battery and allowing the
chain to cool down.
