Causes And Operator Prevention Of Kickback; Personal Protective Equipment - Husqvarna 420 EL Bedienungsanweisung

• Do not attempt to fell a tree until you have
an understanding of the risks and how to avoid
them. Serious injury could occur to the operator or
bystanders while felling a tree.
• Follow all instructions when clearing jammed
material, storing or servicing the chain saw. Make
sure the switch is off and the battery pack is
removed. Unexpected actuation of the chain saw
while clearing jammed material or servicing may
result in serious personal injury.
• Do not operate a chain saw in a tree unless you
have been specifically trained to do so. Operation of
a chain saw in a tree without proper training could
increase the risk of serious personal injury.

Causes and operator prevention of kickback

Kickback may occur when the nose or tip of the guide
bar touches an object, or when the wood closes in and
pinches the saw chain in the cut. Tip contact in some
cases may cause a sudden reverse reaction, kicking the
guide bar up and back towards the operator. Pinching
the saw chain along the top of the guide bar may push
the guide bar rapidly back towards the operator. Either
of these reactions may cause you to lose control of the
saw which could result in serious personal injury. Do not
rely exclusively upon the safety devises built into your
saw. As a chain saw user, you should take several steps
to keep your cutting jobs free from accident or injury.
Kickback is a result of tool misuse and/or incorrect
operating procedures or conditions and can be avoided
by taking proper precautions as given below:
• Maintain a firm grip, with thumbs and fingers
encircling the chain saw handles, with both hands
on the saw and position your body and arm to allow
you to resist kickback forces. Kickback forces can be
controlled by the operator, if proper precautions are
taken. Do not let go of the chain saw.
• Do not overreach and do not cut above shoulder
height. This helps prevent unintended tip contact
and enables better control of the chain saw in
unexpected situations.
• Only use replacement bars and chains specified by
the manufacturer. Incorrect replacement bars and
chains may cause chain breakage and/or kickback.
• Follow the manufacturer's sharpening and
maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead to
increased kickback.
