OPERATING THE SAW
Saw chains are made to cut wood only .
Do not use the chain saw to cut any other
materials, and do not allow the chain
to come into contact with dirt, stones,
nails, staples or wire . These materials are
extremely abrasive and will wear away
protective plating from the chain in a
very short time .
Sharpen or replace the saw chain if any of
these conditions occur:
• The pressure required to make cuts
increases noticeably .
• Wood chips coming off of the chain are
very fine or dust-like .
Do not work with a dull chain as it will
increase the effort required to cut, cause
jagged cuts, increase wear on the chain
saw and increase the risk of kickback .
Never force a dull chain to cut .
• Assume the proper cutting grip and
stance in front of the wood with the saw
turned off . Press the trigger lock-out and
squeeze the trigger switch . Let the chain
reach full speed before beginning the
cut .
• Begin cutting by lightly pressing the
guide bar against the wood . Use only
light pressure and let the saw do the
work .
• Maintain a steady speed throughout the
cut releasing pressure just before the
end of the cut .
• Know the location of the tip of the
bar at all times and avoid contact with
other objects .
• If the saw stops suddenly when
cutting, remove the saw from the cut,
then resume cutting using lighter
pressure on the workpiece .

PRUNING
CAUTION: FALLING LIMBS MAY
BOUNCE OR "SPRING BACK" AFTER
THEY HIT THE GROUND SO IT IS
ESSENTIAL TO KEEP THE GROUND
CLEAR TO PROVIDE MULTIPLE
RETREAT PATHS. Clear the work area and
wear head protection.
Pruning is removing dead or overgrown
branches to maintain plant health .
• Plan retreat paths before beginning
to cut, and make sure there are no
obstructions . Always know how to get
out of the way of falling branches .
• Make sure bystanders or helpers are
a safe distance from falling branches .
Bystanders or helpers should not
stand directly in front of or behind the
operator . See Fig . 28 .
• Maintain solid footing and hold the
chain saw firmly with both hands . Do
not overreach . Never climb a tree or
ladder to reach high limbs .
• Secure any branches that might be
hazardous .
• Use proper auxiliary equipment .
• Prune lower limbs before pruning
higher ones .
• Allow the saw chain to achieve full
speed before cutting .
• Apply light pressure to the branch .
• For long limbs (Fig . 30), cut the end of the
limb first (1) to relieve pressure from the
limb, then prune closer to the trunk (2) .
