HENX H36LJ16 Mode D'emploi page 23

• 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.
• When users find it's difficult to cut the
hard tree or timber, they shall not force
the chain saw to do cutting work by
restarting it frequently.
• 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 (See
Fig. E.).
Kickback safety devices on this chain
6.1
saw
a. 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 forward 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.
To test the operation of the chain brake,
perform the following steps (Fig. 6):
• Place the chain saw on a flat bare
surface and make sure no objects
or obstructions that could come in
contact with the bar and chain are in the
immediate vicinity.
• Disengage the chain brake by pulling the
chain kickback brake andle towards the
front handle.
• Start the chain saw.
• Push the chain kickback brake handle
towards the front of the saw. A properly
functioning hand brake will stop the
movement of the chain immediately. If
the chain brake is not working properly,
do not use the chain saw until it has been
repaired by a qualified service technician.
WARNING: Confirm that the chain brake
works properly before each use.
WARNING: If the chain brake is clogged with
wood chips, the function of the chain brake
may deteriorate. Always keep the device
clean.
b. Low Kickback Saw Chain
The rakers (depth gauges) ahead of each
cutter can minimize the force of a kickback
reaction by preventing the cutters from
digging in too deeply at the kickback
zone. Only use a replacement chain that
is equivalent to the original chain or has
been certified as a low kickback chain. A
low kickback tooth saw chain is a chain
that has met the kickback performance
requirements.
CAUTION: As saw chains are sharpened
during their useful life, they lose some of
the low kickback qualities and extra caution
should be used.
c. Guide bar
This saw comes equipped with a guide bar
that has a small radius nose. Small radius
noses generally have less potential for
kickback. When replacing the guide bar, be
sure to order the bar listed in this manual.
