NOTE!
Icing protection system (Fig.2-4B)
When you use the unit in winter time or cold
weather, move the lever forward (2) to protect
carburetor from icing, otherwise just leave it in
its regular position (1).
Chain brake operation (Fig. 2-5)
Chain brake (1) (If so equipped) is designed to
activate in an emergency such as kick-back
action. Please check to verify that it works
properly before use.
Application of brake is made by moving the
front guard towards the bar. During the chain
brake operation, even if the throttle lever is
pulled, the engine speed does not increase
and the chain does not turn. To release the
brake, pull up the chain brake lever.
How to confirm:
1) Turn off the engine.
2) Holding the chain saw horizontally, release
your hand from the front handle, hit the tip of
the guide bar to a stump or a piece of wood,
and confirm brake operation. Operating level
varies by bar size.
In case the brake is not effective, ask our dealer
for inspection and repairs.
If the engine keeps rotating at high speed with
the brake engaged, the clutch will overheat
causing trouble.
When the brake engages during operation,
immediately release the throttle lever to stop the
engine.
WARNING!
Do not carry the machine with the engine
running.
Stopping (Fig. 2-6)
Decrease engine speed, and push ignition
switch to stop position.
WARNING!
KICKBACK DANGER (Fig. 2-7)
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 firm grip on the saw with
your right hand on the rear handle, your left
hand on the front handle and your thumbs
and fingers encircling the handles. Always
hold the saw with both hands during operation
and cut at high engine speed.
WARNING!
Do not overreach or cut above shoulder
height.
WARNING!
Use extra caution when felling, and do not
use the saw in a nose-high position or
above shoulder height.
CHAIN CATCHER
The chain catcher is located on the power head
just below the chain to further prevent the
possibility of a broken chain striking the
chainsaw user.
WARNING!
Do not stand in-line with chain when
cutting.
BASIC TECHNIQUES FOR MAKING FEL-
LING, LIMBING AND BUCKING CUTS
The intention of the following information is
to provide you with the general introduction
to wood cutting techniques.
WARNING!
This information does not cover all
specific situations, which may depend on
differ-ences in terrain, vegetation, kind of
wood, form and size of trees, etc. Consult
your servicing dealer, forestry agent or
local forestry schools for advice on
specific woodcutting problems in your
area,
This will make your work more efficient
and safer.
WARNING!
Avoid cutting in adverse weather condi-
tions, such as dense fog, heavy rain,
bitter cold, high winds, etc.
Adverse weather is often tiring to work in
and creates potentially dangerous condi-
tions such as slippery ground.
High winds may force the tree to fall in an
unexpected direction causing property
damage or personal injury.
CAUTION!
Never use a chainsaw to pry or for any
purpose for which it is not intended.
WARNING!
Avoid stumbling on obstacles such as
stumps, roots, rocks, branches and fallen
trees. Watch out for holes and ditches. Be
extremely cautious when working on
slopes or uneven ground. Shut off the
saw when moving from one work place to
another.
Always cut at wide open throttle. A slow
moving chain can easily catch and force the
saw to jerk.
