Adjusting the Chain
T ension
Service Interval : Before each use or daily
After each battery drain cycle
Ensure that the chain is properly tensioned.
A loose chain shortens the life of the drive sprocket
and the guide bar and may cause the chain to fall of f.
An overtightened chain overheats the guide bar and
chain, causing rapid wear , and may burn out the motor
or break the chain.
The chain tension is correct when you are able to use
a gloved hand to pull the chain smoothly around the
guide bar . The chain should remain in contact with
the bottom edge of the guide bar .
Also, check the chain tension of a new chain after a
few cuts; a new chain usually stretches and requires
adjustment after a few cuts.
