1. For safe operation
1. Never operate a chain saw when you
are fatigued, ill, or upset, or under the
influence of medication that may
make you drowsy, or if you are under
the influence of alcohol or drugs.
2. Use safety footwear, snug fitting
clothing and eye, hearing and head
protection devices.
Use the vibration-proof glove.
3. Keep the saw chain sharp and the
saw, including the AV system, well
maintained. A dull chain will increase
cutting time, and pressing a dull
chain through wood will increase the
vibrations transmitted to your hands.
A saw with loose components or with
damaged or worn AV buf fers will also
tend to have higher vibration levels.
4. Always use caution when handling
fuel. Wipe up all spills and then move
the chain saw at least 3 m from the
fueling point before starting the engine.
5. Eliminate all sources of sparks or
flame (i.e. smoking, open flames, or
work that can cause sparks) in the
areas where fuel is mixed, poured,
or stored.
6. Do not smoke while handling fuel or
while operating the chain saw.
7. Do not allow other persons to be near
the chain saw when starting or cutting. Keep bystanders and animals
out of the work area. Children, pets
and bystanders should be a minimum
of 10 m away when you start or operate the chain saw.
8. Never start cutting until you have a
clear work area, secure footing, and
a planned retreat path from the falling tree.
9. Always hold the chain saw firmly with
both hands when the engine is running. Use a firm grip with thumb and
fingers encircling the chain saw
handles.
10.Keep all parts of your body away from
the saw chain when the engine is running.
11.Before you start the engine, make
sure the saw chain is not contacting
anything.
12.Always carry the chain saw with the
engine stopped, the guide bar and
saw chain to the rear, and the muffler
away from your body.
13.Always inspect the chain saw befor e
each use for worn, Ioose, or damaged parts. Never operate a chain
saw that is damaged, improperly
adjusted, or is not completely and
securely assembled. Be sure that the
saw chain stops moving when the
throttle control trigger is released.
14.All chain saw service, other than the
items listed in the Owner’s Manual,
should be performed by competent
chain saw service personnel. (E.g.,
if improper tools are used to remove
the flywheel, or if an improper tool is
used to hold the flywheel in order to
remove the clutch, structural damage
to the flywheel could occur which
could subsequently cause the flywheel to disintegrate.)
15.Always shut off the engine before
setting it down.
16.Use extreme caution when cutting
small size brush and saplings because slender material may catch the
saw chain and be whipped toward
you or pull you off balance.
17.When cutting a limb that is under tension, be alert for spring- back so that
you will not be struck when the tension in the wood fibers is released.
18.Never cut in high wind, bad weather,
when visibility is poor or in very high
or low temperatures. Always check
the tree for dead branches which
could fall during the felling operation.
19.Keep the handles dry, clean and free
of oil or fuel mixture.
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 dangerous carbon monoxide.
GB-4
21.Do not operate the chain saw in a tr ee
unless specially trained to do so.
22.Guar d 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 dangerous 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 immediately after shutting down the engine.
Doing so could result in serious burns
because of high temperature.

KICKBACK SAFETY PRECAUTIONS
FOR CHAIN SAW USERS
WARNING
• 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
a lightning fast reverse
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
handle, and the left hand on the front
handle, when the engine is running.
Use a firm grip with thumbs and fingers encircling the chain saw
handles. A firm grip will help you reduce kickback and maintain control
of the saw.
G3700
(3) Make certain 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, 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.
WORSE EFFECTS OF VIBRATION
If you continue to use high-vibration tools these
symptoms will probably get worse, for example:
• the numbness in your hands could become permanent 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 frequently and affect more of your fingers.
FOR PROTECTING YOUR BODY FROM VIBRATION
Please observe the following matter , in order to protect 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 vibration).
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 machine, be sure to allow your local regulations.
