Will the hand always engage the chain brake during a kickback?
No. It is necessary to use some force to push the front hand guard forward. If you do not use the force necessary, the chain brake may not be engaged. This can occur if your hand only lightly touches the front hand guard. You must also hold the handles of the product stable with two hands during work. If a kickback occurs, your hand may not let go of the front handle. Then it will not engage the chain brake, or the chain brake will only engage after the product has moved around a large distance. If this situation occurs, the chain brake may not stop the saw chain before it touches you. There are also some positions in which your hand can not touch the front hand guard to engage the chain brake. An example of this is in the felling position.
Will the inertia release mechanism always engage the chain brake during kickback?
No. First, the chain brake must work correctly. See Maintenance and checks of the safety devices on the product for instructions about how to do a check of the chain brake. We recommend you to do this each time before you use the product. Second, the kickback must be intense to engage the chain brake. If the chain brake is too sensitive it will be engaged all the time.
Will the chain brake always protect me from injury during a kickback?
No. The chain brake must work correctly in order to give the correct protection. The chain brake must also be engaged during a kickback to stop the saw chain. If you are near the guide bar, the chain brake may not have time to stop the saw chain before it hits you.
