A23
The cutting force exerted on the chain from the
saw, a rotational force in the opposite direction
to the chain travel. This leads to an upward
movement of the guide rail.
Avoid kickback
The best protection is to avoid situations that
lead to setbacks.
1 Keep the position of the upper guide rail always
in mind.
2 Leave this place never come into contact with
an object. Cut anything with it. Be especially
careful near wire fences and cutting small, hard
knots, in which the chain can easily pinch.
3 Cut only one branch at a time.
A = Retreat
A24
The withdrawal occurs when the chain on the
underside of the bar suddenly stuck because it
is jammed or encounters a foreign object in the
wood. The chain then pulls the saw forward. The
withdrawal often happens when the chain is not
running at full speed when in contact with the
wood.
Avoid withdrawal
1 Be aware of the forces and situations that can
lead to jamming of the chain on the underside of
the bar.
2 Always start with running at full speed chain to
cut.
B = recoil
A25
The recoil occurs when the chain on top of
rail suddenly stuck because it is jammed or
encounters a foreign object in the wood. The
chain can jerkily hold the saw against the
operator. Rebounds happen often if the top rail is
used for cutting.
Avoid recoil
1 Be aware of the forces and situations that can
lead to jamming of the chain on top of rail.
2 Do not cut more than one branch at a time.
3 Do not tilt the rail to the side when you pull
them out of a cutting gap, since the chain could
get caught otherwise.
