Felling Trees - Ryobi RY40604 Manuel D'utilisation

WORK AREA PRECAUTIONS
See Figure 15.
 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.
 Cut only when visibility and light are adequate
for you to see clearly.
