OPERATING THE POLE SAW
OREGON® Cordless Tool System
POLE SAW MODEL PS250
A WARNING: TO REDUCE THE RISK
OF INJURY, WEAR PROPER BOOTS,
GLOVES, HEAD, EAR, AND EYE
PROTECTION.
A WARNING: TO REDUCETHE RISK
OF INJURY, ALWAYS BE SURE OF
FOOTING AND HOLD THE POLE SAW
FIRMLY WITH BOTH HANDS WHILE
THE MOTOR IS RUNNING.
A
WARNING: FALLING LIMBS MAY
BOUNCE WHENTHEYHITTHE
GROUND. NEVER WORK UNDERTHE
LIMB BEING CUT.
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, the
automatic oiler is functioning, and the
chain is sharp.
Saw chains are made to cut wood only.
Do not use the pole saw to cut any other
materials, and do not allow the chain
to come into contact with dirt or rocks.
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
• The number of cuts possible on one
battery charge decreases
• 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, and increase wear on the
pole saw. Never force a dull chain to cut.
Begin cutting by lightly pressing the
guide bar against the wood. Use only light
pressure, letting the saw do the work.
Maintain a steady speed throughout the
cut, releasing pressure just before the
end of the cut.
If the saw stops suddenly when cutting,
remove the saw from the cut, then resume
cutting using lighter pressure on the limb.
PRUNING
• Clear the work area. 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.
• 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. 1 in "Work area safety".
• Maintain solid footing and hold the
pole saw firmly with both hands. Do not
overreach. Never climb a tree or ladder
to reach high limbs.
• 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. 31), cut the end of the
limb first (1) to relieve pressure from the
limb, then prune closer to the trunk (2).
