_WARNING: When performing the
following procedure, the engine must
be lumed off.
Grip the rear handle with your right
hand and the front handle with your left
hand. Hold the chain saw approxi-
mately 14" (35 cm) above a stump or
other wooden surface. Release your
gdp on the front handle and let the tip
of the guide bar fall fonNard and con-
tact the stump. When the tip of the bar
hitsthe stump, the brake should acti-
vate.
OPERATING TIPS
• Check chain tension before first use
and after 1 minute of operation. See
CHAINTENSION in the MAINTENANCE
section.
• Cut wood only. Do not cut metal, plas-
tics, masonry, non-wood buildingma-
terials, etc.
• Stop the saw ifthe chain strikes a
foreign object. Inspect the saw and
repair parts as necessary.
• Keep the chain out of _lirt and sand.
Even a small amount of dirt will
quickly dull a chain and increase the
possibility of kickback.
• Practice cuttinga few small logs using
the followingsteps. This will help you
get the "feel" of usingyour saw before
you begin a major sawing operation.
• Squeeze the throttle trigger and al-
low the engine to reach full speed
before cutting.
• Begin cutting with the saw frame
against the log.
• Keep the engine at full speed the
entire time you are cutting.
• Allow the chain to cut for you. Exert
only lightdownward pressure.
• Release the throttle trigger as soon
as the cut is completed, allowing
the engine to idle. If you run the
saw at full throttle without a cutting
load, unnecessary wear can occur
to the chain, bar and engine. It is
recommended that the engine
not be operated for longer than
30 seconds at full throttle.
• TOavoid losing control when cut is
complete, do not put pressure on
saw at end of cut.
• Stop engine before settingsaw down.
TREE FELLING TECHNIQUES
WARNING: Check for broken or
dead branches which can fall while
cutting causing sedous injury.Do not
cut near buildings or electrical wires if
you do not know the direction of tree
fall, nor cut at night since you will not
be able to see well, nor during bad
weather such as rain, snow, or strong
winds, etc. If a tree makes contact with
any utility line, the utility company
should be notified immediately.
• Carefully plan your sawing operation
in advance.
• Clear the work area. You need a
clear area all around the tree so you
can have secure footing.
• The chain saw operator should keep
on the uphill side of the terrain as the
tree is likely to roll or slide downhill
after it is felled.
• Study the natural conditions that can
cause the tree to fall in a particular
direction. These conditions include:
• The wind direction and speed.
• The lean of the tree. The lean ofa
tree might not be apparent due to
uneven or sloping terrain. Use a
plumb or level to determine the di-
rection of tree lean.
• Weight and branches on one side.
• Surrounding trees and obstacles.
• Look for decay and rot. If the trunk is
rotted, itcan snap and fall toward the
operator.
• 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. Engine
noise can drown out a warning call.
• Remove dirt, stones, loose bark,
nails, staples, and wire from the tree
where cuts are to be made.
