Basic Cutting Procedure; Work Area Precautions - Ryobi RY40503 Operator's Manual

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.
