OPERATING THE CHAIN SAW
To get the best performance and operate
the saw safely, follow these instructions:
• Observe all applicable national and
municipal rules and regulations for cutting
• Take frequent breaks to reduce the risk of
injury
• Before beginning to cut, make sure the
saw chain is properly tensioned and the
chain is sharp
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 cord at all times to
avoid trip hazards and avoid cutting the cord
• 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 16
• 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 17), cut the end of the
limb first (1) to relieve pressure from the
limb, then prune closer to the trunk (2)
