Kickback
Kickback may occur if the running saw-chain hits or is jammed
against a solid object at the upper quarter of the guide bar.
The cutting force of the chain exerts a rotational force on the saw in
the opposite direction to the chain movement. This results in an
upward movement of the guide bar.
Avoiding kickback
The best protection is to avoid situations that lead to setbacks.
4.
Always keep an eye on the position of the top guide rail.
5.
Never let this point come into contact with an object. Do not cut it. Be especially
careful near wire fences and when cutting small, hard branches where the chain
can easily get caught.
6.
Only cut one branch at a time.
A = Retraction
The retraction (A) occurs when the chain suddenly becomes stuck
on the underside of the bar because it is jammed or hits a foreign
object in the wood. The chain then pulls the saw forward. The
retraction often occurs when the chain does not run at full speed
when it comes into contact with the wood.
Avoid retraction B = Kickback
Be aware of the forces and situations that can cause the chain to
jam at the bottom of the bar.
2.
Always start cutting with the chain running at full speed.
Recoil (B) occurs when the chain is suddenly stuck on the top of
the bar because it is jammed or hits a foreign object in the wood.
The chain can then press the saw against the operator with a jerk.
Kickback often occurs when the bar top is used for cutting.
Avoid kickback
4.
Be aware of the forces and situations that can cause the chain to jam on the top
of the bar.
5.
Do not cut more than one branch at a time.
6.
Do not tilt the bar sideways when pulling it out of a cutting gap, as the chain
could be jammed.
During operation
Check the chain tension regularly!
A new chain must be re-tensioned more often than an older one.
