KICKBACK SAFETY
DANGER:
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. In some cases, tip
contact may cause a lightening-fast reverse action, kicking
the guide bar rapidly back to wards 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 a loss of control over the saw,
which could result in serious injury to the user. Contact
with foreign objects within the wood can also induce a loss
of chain saw control.
Understanding Kickback
•
Rotational Kickback can happen when the upper tip of the guide
bar contacts an object while the chain is moving. This can cause
the chain to dig into the object and momentarily stop moving.
The guide bar is then kicked up and back toward the operator in
a lightning-fast reverse reaction.
•
Pinch Kickback can happen when the wood on either side of a cut
closes in and pinches the moving saw chain along the top of the
guide bar. This can cause the chain to instantly stop. The chain
force is then reversed, causing the saw to move in the opposite
direction, sending the saw straight back toward the operator.
•
Pull-In can happen when the moving chain on the bottom of the
guide bar hits a foreign object inside the wood. This can cause
the chain to suddenly stop. The saw is then pulled forward and
away from the operator, which could potentially result in the loss
of control of the saw.
Kickback Safety Precautions
•
Do not rely exclusively upon the safety devices built into the unit.
•
Do not extend arms above shoulder height.
•
Do not make cuts with the tip of the guide bar.
•
Do not let the tip of the guide bar contact any object, such as a
log, branch, ground or other obstruction.
•
Do not operate the unit with one hand! Serious injury to the
operator, helpers or bystanders may result from one-handed
operation. This unit is intended for two-handed use. Always grip
the unit firmly with both hands when the unit is running.
•
Stand slightly to the left of the unit to avoid being in the direct
line of the saw chain.
•
Never start the saw when the guide bar is inside an existing cut.
Be extremely careful when re-entering a cut.
•
Always begin a cut with the unit running at full speed. Fully
squeeze the throttle control and maintain a steady cutting
speed. Slower speeds increase the chance of kickback.
•
Follow the manufacturer's sharpening and maintenance
instructions for the saw chain.
•
Only use replacement bars and chains specified by the
manufacturer or the equivalent. These are available from
authorized service dealers. Use of any unauthorized parts or
accessories could lead to serious injury to the operator or
damage to the unit and will void the warranty.
•
Use devices, such as low-kickback chains and reduced-
kickback guide bars, which reduce the risks associated with
kickback. There are no other replacement components for
achieving kickback protection in accordance with CSA Z62.3.
•
Low-kickback saw chain is chain that has met the kickback
performance requirements of ANSI B175.1-2000 and is in
accordance with CSA Z62.3. Do not use a replacement chain
unless it has met these requirements for the specific model. As
saw chains are sharpened, some of the low kickback qualities
are lost and extra caution should be used.
OTHER SAFETY WARNINGS
•
All service, other than the maintenance procedures described in
this manual, should be performed by a authorized service dealer.
