○ All chain saw service, other than the items listed in the
operatorʼs/ ownerʼs manual, should be performed by competent
chain-saw service personnel. (For example,
if improper tools are
used to remove the fl ywheel or if an improper tool is used to hold
the fl ywheel in order to remove the clutch, structural damage
to the fl ywheel could occur and could subsequently cause the
fl ywheel to burst.)
WARNING
○ Never modify the unit/machine in any way. Do not use your unit/
machine for any job except that for which it is intended.
○ Never use chain saw without any safety equipment or that has
faulty safety equipment. It could result in serious personal injury.
○ Using guide bar/chain other than
recommended by the
manufacturer which are not approved, could result in a high risk
of personal accidents or injury.
Fuel safety
○ Mix and pour fuel outdoors and where there are no sparks or
fl ames.
○ Use a container approved for fuel.
○ Do not smoke or allow smoking near fuel or
the unit/machine or
while using the unit/machine.

○ Move at least 3 m away from fueling site before starting engine.
○ Stop engine and let it cool for a few minutes before removing fuel
tank cap.
○ Empty the fuel tank before storing
the unit/machine. It is
recommended that the fuel be emptied after each use. If fuel is
left in the tank, store so fuel will not leak.
○ Store unit/machine and fuel in area where fuel vapors cannot
reach sparks or open fl ames from water heaters, electric motors
or switches, furnaces, etc.
WARNING
Fuel is easy to ignite or get explosion or inhale fumes, so that pay
special attention when handling or fi lling fuel.
Cutting safety
○ Do not cut any material other than wood or wooden objects.
○ For respiratory protection, wear an aerosol protection mask
when cutting the wood after insecticide has
been applied.

○ Before felling a tree, the operator must be accustomed to the
sawing techniques of the chain saw.
○ Be sure to pre-plan a safe
exit from a failing tree.
○ While cutting, hold the unit/machine fi rmly with both hands with
thumb fi rmly locked around front handle, and stand with feet well
balanced and your body balanced.
○ Stand to the side of the saw when cutting - never directly behind
it.
○ Always keep the spiked
bumper face to a tree, because the
chain may suddenly be drawn into a tree, if so equipped.
○ When completing a cut, be ready to hold up the units as it breaks
into clear, so it will not follow through and cut your legs, feet or
body, or contact an
obstruction.
○ Be alert against kickback (when saw kicks up and back at
operator). Never cut with the nose of the bar.
○ When relocating to a new work area, be sure to shut off the
machine and ensure that all cutting attachments are stopped.
○ Never place the machine on the
ground when running.
○ Always ensure that the engine is shut off and any cutting
attachments have completely stopped before clearing debris or
removing grass from the cutting attachment.
○ Always carry a fi rst-aid kit when operating any power equipment.
○ Never start or run the engine inside a closed room
or building
and/or near the infl ammable liquid. Breathing exhaust fumes
can kill.

WARNING
KICKBACK DANGER (Fig. 1)
One of the most severe dangers when working with a chain saw is
the possibility of kickback. Kickback may occur when the upper 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 lightning fast reverse reaction, kicking the guide bar up and
back toward you. Pinching the saw chain along the top of the guide
bar may also push the guide bar rapidly back towards you. Either of
these reactions may cause you to lose control
of the saw which could
result in serious personal injury. Even though your saw has safety
built into its design, you should not rely on these safety features
exclusively. Know where your bar tip is at all times. Kickback does
occur if you allow the kickback zone (1) of the bar
to touch an object.
Do not use that area. Kickback from pinching is caused by a cut
closing and pinching the upper side of the guide bar. Study your cut
and make sure it will open as you cut through. Maintain control when
the engine is running by always keeping
a fi rm grip on the saw with
your right hand on the rear handle, your left hand on the front handle
and your thumbs and fi ngers encircling the handles. Always hold the
saw with both hands during operation and cut at high engine speed.
Follow manufacturer's sharpening and maintenance instructions
for
the saw chain. The lack of this maintenance may increase the
possibility of kickback.
