WARNING:
When performing
the
following
procedure,
the engine must
be turned off.
Grip the rear handle with your right hand
and the front handle with your left hand.
Hold the chain saw approximately
14"
(35 cm) above a stump or other wooden
surface. Release your grip on the front
handle and let the tip of the guide bar
fall forward and contact the stump.
When the tip of the bar hits the stump,
the brake should activate.
OPERATING
TIPS
• Check chain tension
before first use
and after 1 minute of operation.
See
CHAIN TENSION in the MAINTENANCE
section.
• Cut wood only. Do not cut metal,
plastics,
masonry, non-wood
building
materials,
etc.
• Stop the saw if the chain strikes a
foreign object. Inspect the saw and
repair parts as necessary.
• Keep the chain out of dirt and sand.
Even a small amount of dirt will
quickly dull a chain and increase the
possibility
of kickback.
• Practice cutting a few small logs us-
ing the following
steps. This will help
you get the "feel" of using your saw
before you begin a major sawing op-
eration.
• 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 light downward
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.
• To avoid losing control when cut is
complete,
do not put pressure
on
saw at end of cut.
• Stop engine before setting saw down.
TREE FELLING
TECHNIQUES
_& WARNING:
Check for broken or
dead branches which can fall while
cutting causing serious 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 the tree does make con-
tact with any utility line, the utility com-
pany 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 of a
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, it can 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.
