•
Cut branches under tension from the bottom up to avoid
binding the pole chain saw.
•
Keep the tree between you and the pole chain saw while
limbing. Cut from the side of the tree opposite the branch
you are cutting.
If the Saw Becomes Pinched or Trapped
1.
Wait for the blade to stop, wait five minutes for the saw to
cool, unplug the power cord, and wear gloves to protect
your hands from the chain teeth.
2. If you can reach the limb from the ground, lift the limb
while holding the saw. This should release the “pinch” and
free the saw.
3. If the saw is still trapped, call a professional for assistance.
Minimize Kickback
Kickback may occur when the moving chain contacts an
object at the upper portion of the tip of the guide bar or when
the wood closes in and pinches the pole chain saw in the
cut. Contact at the upper portion of the tip of the guide bar
can cause the chain to dig into the object and stop the chain
for an instant. The result is a lightning-fast reverse reaction,
which kicks the guide bar up and back toward the operator. If
the pole chain saw is pinched along the top of the guide bar,
the guide bar can be driven rapidly back toward the operator.
Either of these reactions can cause loss of saw control, which
can result in serious injury. Do not rely exclusively upon the
safety devices built into the saw. As a pole chain saw user, you
should take several steps to keep your cutting jobs free from
accident or injury.
Take the following precautions to minimize kickback:
•
Before you start the unit, make sure the pole chain saw is
not contacting any object.
• Always grip the pole and handle firmly with both hands
when the unit is running. Place one hand on the pole and
your other hand on the molded handle with your thumbs
and fingers encircling the pole and handle. A firm grip
combined with proper positioning of the handle against
your body will help you maintain control of the saw if
kickback occurs.
•
Make sure that the area in which you are cutting is free
from obstructions.
•
Do not let the kickback danger zone area of the guide bar
contact a log, branch, fence, or any other obstruction that
could be hit while you are operating the pole chain saw
(Fig. 12).
•
Always cut with the unit running at full speed. Fully
squeeze the ON/OFF trigger and maintain a steady
cutting speed.
•
Wear non-slip gloves for maximum grip and protection.
•
Extend the pole only to the length required to reach
the limb cut. Do not extend the rear handle above
waist height.

WARNING!
Always unplug the power cord before
performing any adjustments, maintenance, or repairs to your
pole chain saw.
•
Use protective gloves when handling the bar and chain.
• Keep the bar encased in its sheath, except when working
directly on the bar or the chain.
•
Never dispose of oils or other polluting materials in
unauthorized places.
Motor Cooling
To avoid overheating and damage to the motor, always keep
the cooling air vents clean and free of sawdust and debris.
Chain Tension
Check the chain tension before using the saw when the chain
is cold. The correct tension of a cold chain is when there is no
slack on the underside of the guide bar; the chain is snug, but
you can rotate it by hand without binding.
During normal saw operation, the temperature of the chain will
increase. The drive links of a correctly tensioned warm chain
will hang approximately 0.050 in. (1.25 mm) out of the bar
groove (Fig. 22). Be aware that a chain tensioned while warm,
may be too tight upon cooling. Check the “cold tension” before
next use. The chain must be re-tensioned whenever the flats
on the drive links hang out of the bar groove (Fig. 22).
