Poulan 2450 Chainsaw User Manual


 
Cut shattered wood very carefully; sharp
pieces of wood could be flung toward op-
erator.
Use a sawhorse to cut small logs. Never
allow another person to hold the log while
cutting and never hold the log with your
leg or foot.
Do not cut in an area where logs, limbs,
and roots are tangled such as in a blown
down area. Drag the logs into aclear area
before cutting by pulling out exposed and
cleared logs first.
Make the first bucking cut 1/3 of the way
through the log and finish with a 2/3cut on
the opposite side. As the log is being cut,
itwill tend to bend. The saw can become
[)inched or hung in the log ifyou make the
first cut deeper than 1/3of the diameter of
the log.
Give special attention to logs under strain
to prevent the saw from pinching. Make
the first cut on the pressure side to relieve
the stress on the log.
TYPES OF CUTTING USED FOR
BUCKING
WARNING: If saw becomes pinched or
hung in a log, don't try to force it out. You
can lose control of the saw resulting in injury
and/or damage to the saw. Stop the saw,
drive a wedge of plastic or wood into the cut
until the saw can be removed easily. Restart
the saw and carefully reenter the cut. To
avoid kickback and chain damage, do not
use a metal wedge. Do not attempt to re-
start saw when itis pinched or hung in alog.
Overcutting Undercutting
Overcutting begins on the top side of the
log with the bottom of the saw against the
log. When overcetting use light downward
pressure.
Undereutting involves cutting on the un-
derside of the log with top ofsaw against the
log. When undercutting use light upward
pressure. Hold saw firmly and maintain
control. The saw will tend to push back to-
ward you.
WARNING: Never turn saw upside
down to undercut. The saw cannot be con-
trolled in this position.
BUCKING WITHOUT A
SUPPORT
Overcutthrough 1/3ofthediameter ofthe
log.
Roll the log over and finish with a second
overcet.
Watch for logs with a pressure side. See
illustration for cutting logs with a pressure
side.
