 Maintain a proper grip on the saw whenever the
engine is running. The fingers should encircle
the handle and the thumb is wrapped under the
handlebar. This grip is least likely to be broken
by a kickback or other sudden reaction of the
saw. Any grip in which the thumb and fingers
are on the same side of the handle is dangerous
because a slight kick of the saw can cause loss
of control.
PROPER CUTTING STANCE
See Figure 17.
WARNING:
Always use the proper cutting stance described
in this section. Never kneel when using the
chain saw, except when felling a tree as illus-
trated in Figure 22. Kneeling could result in
loss of stability and control of the chain saw,
resulting in serious personal injury.
 Balance your weight with both feet on solid
ground.
 Keep left arm with elbow locked in a "straight
arm" position to withstand any kickback force.
 Keep your body to the left of the chain line.
 Keep your thumb on underside of handlebar.
WORK AREA PRECAUTIONS
See Figure 18.
 Cut only wood or materials made from wood;
no sheet metal, no plastics, no masonry, no
non-wood building materials.
 Never allow children to operate the saw. Allow
no person to use this chain saw who has not
read this operator's manual or received ade-
quate instructions for the safe and proper use
of this chain saw.
 Keep everyone – helpers, bystanders, children,
and animals, a safe distance from the cutting
area. During felling operations, the safe dis-
tance should be a least twice the height of the
largest trees in the felling area. During bucking
operations, keep a minimum distance of 15 feet
between workers.
 Always cut with both feet on solid ground to
prevent being pulled off balance.
OPERATION
THUMB ON
UNDERSIDE OF
HANDLE BAR
 Do not cut above chest height as a saw held
higher is difficult to control against kickback
forces.
 Do not fell trees near electrical wires or build-
ings. Leave this operation for professionals.
 Cut only when visibility and light are adequate
for you to see clearly.
BASIC OPERATING/CUTTING
PROCEDURES
Practice cutting a few small logs using the following
technique to get the "feel" of using the saw before
you begin a major sawing operation.
 Take the proper stance in front of the wood with
the saw idling.
 Accelerate the engine to full throttle just before
entering the cut by squeezing the throttle trigger.
 Begin cutting with the saw against the log.
