20. Operate the chain saw only in well

ventilated areas. Never start or run
the engine inside a closed room or
building. Exhaust fumes contain dan-
gerous carbon monoxide.

21. Do not operate the chain saw in a tree

unless specially trained to do so.

22. Guard against kickback. Kickback is

the upward motion of the guide bar
which occurs when the saw chain at
the nose of the guide bar contacts
an object. Kickback can lead to dan-
gerous loss of control of the chain
saw.

23. When transporting your chain saw,

make sure the appropriate guide bar
scabbard is in place.

24. Never touch the cover, guide bar, saw

chain or nut with bare hands while
the engine is in operation or immedi-
ately after shutting down the engine.
Doing so could result in serious burns
because of high temperature.

handle, and the left hand on the front
handle, when the engine is running.
Use a firm grip with thumbs and fin-
gers encircling the chain saw
handles. A firm grip will help you re-
duce kickback and maintain control
of the saw.

(3) Make certain that the area in which

you are cutting is free from obstruc-
tions. Do not let the nose of the guide
bar contact a log, branch, or any
other obstruction which could be hit
while you are operating the saw.

(4) Cut at high engine speeds.
(5) Do not overreach or cut above shoul-

der height.

(6) Follow the manufacturer’s sharpening

and maintenance instructions for the
saw chain.

(7) Only use replacement bars and

chains specified by the manufacturer
or the equivalent.

•

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

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 Iose control of the saw, which
could result in serious personal injury.

•

Do not rely exclusively on the safety
devices built into your saw. As a chain
saw user you should take several
steps to keep cutting jobs free from
accident or injury.

(1) With a basic understanding of kick-

back you can reduce or eliminate the
element of surprise. Sudden surprise
contributes to accidents.

(2) Keep a good grip on the saw with

both hands, the right hand on the rear

If you continue to use high-vibration tools these
symptoms will probably get worse, for example:

•

the numbness in your hands could become perma-
nent and you won’t be able to feel things at all;

•

you will have difficulty picking up small objects such
as screws or nails;

•

the vibration white finger could happen more fre-
quently and affect more of your fingers.

Please observe the following matter, in order to pro-
tect the health of your body.

1. Always use the right tool for each job (to do the job

more quickly and expose you to less hand-arm vi-
bration).

2. Check tools before using them to make sure they

have been properly maintained and repaired to avoid
increased vibration caused by faults or general wear.

3. Make sure cutting tools are kept sharp so that they

remain efficient.

4. Reduce the amount of time you use a tool in one go,

by doing other jobs in between.

5. Avoid gripping or forcing a tool or workpiece more

than you have to.

6. Store tools so that they do not have very cold handles

when next used.

7. Encourage good blood circulation by:
•

keeping warm and dry (when necessary, wear
gloves, a hat, waterproofs and use heating pads if
available);

•

giving up or cutting down on smoking because
smoking reduces blood flow; and massaging and
exercising your fingers

When disposing your machine, fuel or oil for the ma-
chine, be sure to allow your local regulations.
