Hazards caused by kickback

ENGLISH 14 - 36 -.

9. Hazards caused by kickback

When working with the chainsaw,

careless or incorrect working methods

can cause a dangerous situation which is

referred to as "kickback". Kickback forces can occur

when the running saw chain comes into contact with

solid objects or if the saw chain suddenly gets stuck

in the cut. In the process, the chainsaw is

accelerated violently and uncontrollably.

Depending on the contact point of the running saw

chain, the forces acting on the chainsaw are directed

as follows, resulting in the corresponding

acceleration of the tool:

1. Contact point at the tip of the guide bar:

(schematic

diagram)

Danger: The guide bar is kicked up suddenly

and quickly. As the user is holding the

chainsaw by the handles, this results in a rotational

acceleration of the chainsaw, during which the guide

bar is accelerated towards the head of the operator.

Although this rotational acceleration instantly

activates the chain brake, the magnitude of the

acceleration and the uncontrolled response of the

operator can result in serious accidents.

2. Contact point in the upper part of the guide bar:

Danger: The chainsaw is kicked suddenly in the

direction of the operator. The magnitude of the

acceleration and the uncontrolled response of the

operator can result in serious accidents.

Experienced users can perform a so-called "backhand

cut". This can only be done by anticipating the sudden

acceleration of the tool and supporting the chainsaw in

a rearward direction with your thigh before positioning

the tool for the cut and while performing the cut.

Inexperienced users must not use the

"backhand cut"!

Contact point in the lower part of the guide bar

(bumper spikes (26) as the point at which the

chainsaw is positioned on the cutting object):

Safe application: The chainsaw is pulled towards

the object being sawn. As the bumper spikes (26) on

the engine housing are positioned on the object being

sawn, the chainsaw cannot be accelerated away. The

operator is able to control the tool safely.

The following general guidelines should be followed

in order to avoid kickback:

• Always hold the chainsaw firmly with both hands.

Position your right hand on the rear handle

and your left handle on the front handle.

• Before positioning the saw for the cut, apply the

throttle and, with the saw chain running, start the

cut on the underside of the guide bar as close as

possible to the engine housing.

• Never cut more than one branch at a time. When

removing branches, bear in mind that other

branches may inadvertently come into contact with

the saw chain. When cutting to length, look out for

other trunks which may be close nearby.

• Special care is required when continuing cuts

which have already been started.

• Carefully watch the guide bar during the cut.

• Look out for forces which could compress the cut

gap and cause the saw chain to become trapped,

particularly on objects which are under tension.

• Always follow the correct procedure for sharpening

the saw chain. In the process, pay particular

attention to the correct height of the depth limiter.

Professional users can use special working

techniques which must only be carried out by

experienced users. We recommend that anyone who

wishes to safely learn about the more difficult

techniques which are not described here should

attend a special course (e.g. at specialist forestry

training centre).
