WORK AREA PRECAUTIONS
See Figure 14.
 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 instruc-
tions 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
operations, 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 pre-
vent being pulled off balance.
 Do not cut above chest height, as a saw held high-
er is difficult to control against kickback forces.
 Do not fell trees near electrical wires or buildings.
Leave this operation for professionals.
 Cut only when visibility and light are adequate for
you to see clearly.
