◾
Use extreme caution when cutting brush and saplings.
The slender material may catch the saw chain and be
whipped toward you or pull you off balance.
◾
Carry the chain saw by the front handle with the
chain saw switched off and away from your body.
When transporting or storing the chain saw always
fit the guide bar cover. Proper handling of the chain
saw will reduce the likelihood of accidental contact
with the moving saw chain.
◾
Follow instructions for lubricating, chain
tensioning and changing accessories. Improperly
tensioned or lubricated chain may either break or
increase the chance for kickback.
◾
Cut wood only. Do not use chain saw for purposes
not intended. For example: do not use chain saw
for cutting plastic, masonry or non-wood building
materials. Use of the chain saw for operations different
than intended could result in a hazardous situation.
◾
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.
◾
This chain saw is not intended for tree felling.
Use of the chain saw for operations different than
intended could result in serious injury to the operator
or bystanders.
◾
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.
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 (Fig. A).
Tip contact in some cases may cause a sudden reverse
reaction, kicking the guide bar up and back towards the
operator (Fig. B).
Pinching the saw chain along the top of the guide bar may
push the guide bar rapidly back towards the operator (Fig. C).
Either of these reactions may cause you to lose con-trol of
the saw which could result in serious personal injury. Do not
rely exclusively upon the safety devices 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 the 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 (Fig. D). 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.
◾
Make sure that the area in which you are cutting
is free from obstructions. Do not let the nose of the
guide bar contact a log, branch, fence, or any other
obstruction that could be hit while you are operating
the saw.
◾
Always cut with the unit running at full speed. Fully
squeeze the switch trigger and maintain cutting speed.
◾
With a basic understanding of kickback, you can
reduce or eliminate the element of surprise. Sudden
surprise contributes to accidents.
◾
Keep proper footing and balance at all times.
◾
Push and Pull – The reaction force is always opposite
to the direction the chain is moving where wood
contact is made. Thus, the operator must be ready to
control the PULL when cutting on the bottom edge of
the bar, and the PUSH when cutting along the top edge
(Fig. E).
KICKBACK SAFETY DEVICES ON THIS CHAIN SAW
CHAIN BRAKE
The chain saw comes equipped with a chain brake, which
stops both the motor and the motion of the chain when
kickback occurs. The chain brake can be activated by the
for-ward motion of the chain kickback brake handle as
the saw rotates backward during kickback; it can also
be activated by the inertial forces generated during rapid
pushback.
WARNING:
Never modify or attempt to disable the
chain brake.
Make sure that the chain brake is working properly before
using the chain saw. The chain kickback brake handle
should move back and forth easily.
