increases the risk of kickback and the chain may
ride out of the bar channel; these events can
cause injury the operator and damage to the

chain. An excessively slack chain will result in
rapid wear of chain, bar and sprocket. On the
contrary, an over tensioned chain will tend to

overload the motor with resulting damage. A
correctly tensioned chain provides the best

of the chain depends on correct tensioning and
correct lubrication.
