2. Make sure the throttle lock works correctly and is not damaged.

3. Make sure the stop button works correctly and is not damaged.

9.2 KICKBACKS, SKIDDING, BOUNCING AND FALLING

WARNING

Reaction forces can occur during chain rotation and can affect the safe control of

the chain saw. These forces can be very dangerous as they result in movement and/

or loss of control of the chain saw which can cause serious injury or death.

Understanding these forces helps you to reduce the corresponding risks.

The most common reactive forces are:

• Skidding: occurs when the bar slips or moves quickly on the wood.

• Bouncing: occurs when the bar lifts off the wood and hits it repeatedly.

• Falling: occurs when the chain saw falls down at the end of the cut. This can cause the

moving chain to touch parts of the body or other objects, causing injury or damage.
