CAUTION:
The chain brake must be
checked several times daily. The engine
must be running when performing this
procedure.
This is the only instance
when the saw should be placed on the
ground with the engine running.
Place the saw on firm ground. Hold the
handles with both hands and apply full
throttle. Activate the chain brake by turn-
ing your left wrist against the hand guard
without releasing your grip around the
front handle. The chain should stop im-
mediately.

_,WARNING:
When performing
the
following
procedure,
the engine must
be turned off.
Hold the chain saw approximately
14"
(35 cm) above a stump or other wooden
surface. Release your grip on the front
handle and use the weight of the saw to
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
CHECK CHAIN TENSION in the SER-
VICE AND ADJUSTMENTS 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 trigger switch and al-
low unit to reach full speed before
cutting.
• Begin cutting with the saw frame
against the log.
• Keep the motor at full speed the
entire time you are cutting.
• Release the trigger switch as soon
as the cut is completed,
allowing
the motor to stop.
• Keep the cord away from the cut-
ting area. Position cord so it will
not be caught in branches and the
like during cutting.
• To avoid losing control when cut is
complete,
do not put pressure
on
saw at end of cut.
• Stop motor before setting saw down.
TREE FELLING
TECHNIQUES
Check for broken or dead branches
which can fall while cutting causing se-
rious 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 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, such as:
• 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.
Motor 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.
