OPERATING TIPS
S Check chain tension before first use and
after 1 minute of operation. See CHAIN
TENSION in the ASSEMBLY section.
S Cut wood only. Do not cut metal, plastics,
masonry , non-wood building materials, etc.
S Stop the saw if the chain strikes a foreign
object. Inspect the saw and repair or re-
place parts as necessary.
S Keep the chain out of dirt and sand. Even a
small amount of dirt will quickly dull a chain
andthusincreasethepossibility ofkickback.
S Practicecutting afew smalllogs using the
following techniques togetthe“feel”ofus-
ing your saw before you begin a major
sawing operation.
S Squeeze the throttle trigger and allowthe
engine to reach full speed before cutting.
S Begin cutting with the saw frame
against the log.
S Keeptheengine atfullspeed theentire

S Release the throttle trigger as soon as
the cut is completed, allowing the en-
gine to idle. If you run the saw at full
throttlewithoutacuttingload,unneces-
sary wear can occur to the chain, bar,
and engine. It is recommended that

S The chain saw operator should keep on
the uphill side of the terrain as the tree is

S Study the natural conditi ons that can cause
the tree to fall in a particular direction.
Natural conditions that can cause a tree to
fall in a particular direction include:
S The wind direction and speed.
S The lean of the tree. The lean of a tree
might not be apparent due to uneven or
slopingterrain. Useaplumborlevel tode-
termine the direction of tree lean.
S Weight and branches on one side.
S Surrounding trees and obstacles.
Look for decay and rot. If thetrunk isrotted,
it can snap and fall toward the operator.
Check for broken or dead branches which
can fall on you while cutting.
Make sure there is enough room for the tree to
fall. Maintain a distance of
2-1/2 tree lengths
from the nearest person or other objects. En-
gine noise can drown out a warning call.
Remove dirt, stones, loose bark, nails, sta-
ples,andwirefromthetreewherecutsareto

FELLING LARGE TREES
(6 inches (15 cm) in diameter or larger)
The notch method is used to felllarge trees.

sired direction of fall. After a felling cut is
made on the opposite side of tree, the tree
will tend to fall into the notch.

NOTCH CUT AND FELLING TH E
