PROPER CUTTING STANCE
See Figure 11 - 12.
WARNING:
Alway use the proper cutting stance described
in this section. Never kneel when using the
chain saw except when felling a tree as shown
in figure 12. Kneeling could result in loss of sta-
bility and control of the saw resulting in serious
personal injury.
 Weight should be balanced with both feet on
solid ground.
 Keep left arm with elbow locked in a "straight
arm" position to withstand any kickback force.
 Your body should always be to the left of the
chain line.
 Thumb should be on underside of handlebar.
BASIC CUTTING PROCEDURE
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 off.
 Squeeze the switch trigger and let the chain
accelerate to full speed before entering the cut.
 Begin cutting with the saw against the log.
 Keep the unit running the entire time you are
cutting, maintain a steady speed.
 Allow the chain to cut for you; exert only light
downward pressure. If you force the cut, dam-
age to the bar, chain, or unit can result.
 Release the switch trigger as soon as the cut
is completed, allowing the chain to stop. If you
run the saw without a cutting load, unnecessary
wear can occur to the chain, bar, and unit.
 Do not put pressure on the saw at the end of cut.
WORK AREA PRECAUTIONS
 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-
OPERATION
CHAIN LINE
quate instructions for the safe and proper use
of this chain saw.
 When felling a tree, keep everyone - helpers,
bystanders, children, and animals - a safe dis-
tance from the cutting area. During felling opera-
tions, the safe distance should be a least twice
the height of the largest trees in the felling area.
During bucking opetations, keep a minimum dis-
tance of 15 feet between workers. Trees should
not be felled in a manner that would endanger
any person, strike any utility line or cause any
property damage. If the tree does make contact
with any utility line, the utility company should
be notified immediately.
 Always cut with both feet on solid ground to
prevent being pulled off balance.
 Do not cut above chest height, as a saw held high-
er is difficult to control against kickback forces.
