Common Questions About Kickback; To Use The Cutting Technique - Husqvarna 120i Manual De Usuario

Common questions about kickback

• 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 will not be engaged. You
must also hold the handles of the product stable with
two hands during work. If a kickback occurs, it is
possible that the chain brake does 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 operate correctly.
Maintenance and checks of the safety
Refer to
devices on the product on page 22 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 force of the kickback must
be large to engage the chain brake. If the chain
brake is too sensitive, it can engage during rough
operation.
• Will the chain brake always protect me from
injury during a kickback?
No. The chain brake must operate correctly to give
protection. The chain brake must also be engaged
during a kickback to stop the saw chain. If you are
near the guide bar, it is possible that the chain brake
does not have time to stop the saw chain before it
hits you.
WARNING: Only you and the correct
working technique can prevent kickbacks.

To use the cutting technique

WARNING: Use full power when you cut
and decrease the speed to idle after each
cut.
CAUTION: Motor damage can occur if the
motor runs for too long at full power without
load. For example if the motor runs for too
long without resistance from the saw chain
during cutting.
You can use the product to cut through wood in two
different positions.
• To cut on the pull stroke is when you cut with the
bottom of the guide bar. The saw chain pulls through
the tree when you cut. In this position you have
16
better control of the product and the position of the
kickback zone.
• To cut on the push stroke is when you cut with the
top of the guide bar. The saw chain pushes the
product in the direction of the operator.
WARNING: Be careful when you cut on
the push stroke. If the saw chain gets
trapped in the trunk, the product can be
pushed at you. You must prevent this
force or there is a risk that the kickback
zone of the guide bar touches the tree.
This will lead to a kickback.
1. Put the trunk on a saw horse or runners.
