OPERATION 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, damage 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 See Figure 13.  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 adequate 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 distance 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.  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 buildings.

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
See Figure 13.
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.
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.
