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
andthus increasethepossibility ofkickback.
S Practice cutting afew smalllogs using the
followingtechniques toget the“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 Keepthe engineatfull speedtheentire

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

TREE FELLING TECHNIQUES
WARNING: Check for broken or
dead br anches which can fall while cutting
causing serious injury . Do not cut near build-
ings or electrical wires if you do not know the
direction of tree fall, nor cut at night since you
will not b e ale to see well, nor during bad
weather such as rain, snow, or strong winds,
etc. If the tree makes contact with any utility
line, the utility company should be notified im-
mediately.
S Carefullyplanyoursawingoperationinad-
vance.
S Clear the work area. You need a clear area
all around the tree so you can have secure
footing.
S The chain saw operator should keep on
the uphill side of the terrain as the tree is
likelytorollorslidedownhillafteritisfelled.
S Study the natural conditions 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. Useaplumborleveltode-
termine the direction of tree lean.
S Weight and branches on one side.
S Surrounding trees and obstacles.
Look for decay and rot. Ifthetrunk 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. E n-
gine noise can drown out a warning call.
Remove dirt, stones, loose bark, nails, sta-
ples,andwirefromthetreewherecutsareto
