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.
 When felling a tree, 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 opetations, keep a
minimum distance 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.
