Limbing And Pruning - Partner P842 Manual De Instrucciones

Important points
S Cut only one log at a time.
S Cut shattered wood very carefully; sharp
pieces of wood could be flung toward oper-
ator.
S 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.
S Do not cut in an area where logs, limbs,
and roots are tangled. Drag the logs into a
clear area before cutting by pulling out ex-
posed and cleared logs first.
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. Do not
attempt to restart your saw when it is pinched
or hung in a log.
Turn saw and use a plastic or
OFF
wooden wedge to force cut open.
Overcutting begins on the top side of the log
with the saw against the log. When overcut-
ting use light downward pressure.
Overcutting
Undercutting
Undercutting involves cutting on the under-
side of the log with top of saw against the log.
When undercutting use light upward pres-
sure. Hold saw firmly and maintain control.
The saw will tend to push back toward you.
WARNING
: Never turn saw upside
down to undercut. The saw cannot be con-
trolled in this position.

BUCKING WITHOUT A
SUPPORT
S Overcut through of the diameter of the
1/3
log.
S Roll the log over and finish with a second
overcut.
S 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.
BUCKING USING A LOG OR SUP-
PORT STAND
S Remember your first cut is always on the
pressure side of the log.
S Your first cut should extend
diameter of the log.
S Finish with your second cut.

LIMBING AND PRUNING

WARNING
: Be alert for and guard
against kickback. Do not allow the moving
chain to contact any other branched or objects
at the nose of the guide bar when limbing or
pruning. Allowing such contact can result in
serious injury.
WARNING
: Never climb into a tree to
limb or prune. Do not stand on ladders, plat-
forms, a log, or in any position which can cause
you to lose your balance or control of the saw.
IMPORTANT POINTS
S Watch out for springpoles. Use extreme
caution when cutting small size limbs. Slen-
der material may catch the saw chain and be
whipped toward you or pull you off balance.
