Reactive forces including kickback

!Warning!

Reactive forces may occur any time the

chain is rotating. Reactive forces can

cause serious personal injury.

The powerful force used to cut wood can

be reversed and work against the

operator. If the rotating chain is suddenly

stopped by contact with any solid object

such as a log or branch or is pinched, the

reactive forces may occur instantly.

These reactive forces may result in loss

of control, which, in turn, may cause

serious or fatal injury. An understanding

of the causes of these reactive forces

may help you avoid the element of

surprise and loss of control. Sudden

surprise contributes to accidents.

The most common reactive forces are:

–kickback,

– pushback,

–pull-in.

Kickback:

Kickback may occur when

the moving saw chain

near the upper quadrant

of the bar nose contacts a

solid object or is pinched.

The reaction of the cutting force of the

chain causes a rotational force on the

chainsaw in the direction opposite to the

chain movement. This may fling the bar

up and back in a ligtening fast reaction in

an uncontrolled arc mainly in the plane

of the bar. Under some cutting

circumstances the bar moves towards

the operator, who may suffer severe or

fatal injury.

Kickback may occur, for example,

when the chain near the upper quadrant

of the bar nose contacts the wood or is

pinched during limbing or when it is

incorrectly used to begin a plunge or

boring cut.

The greater the force of the kickback

reaction, the more difficult it becomes for

the operator to control the saw. Many

factors influence the occurrence and

force of the kickback reaction. These

include chain speed, the speed at which

the bar and chain contact the object, the

angle of contact, the condition of the

chain and other factors.

The type of bar and saw chain you use

is an important factor in the occurrence

and force of the kickback reaction. Some

STIHL bar and chain types are designed

to reduce kickback forces. STIHL

recommends the use of reduced

kickback bars and low kickback chains.
