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. 13).
• 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 remove the battery from its housing
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. 28). 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. 28).
NOTE: A new chain tends to stretch. Check the chain tension
frequently and re-tension as needed.
Nuts and Screws
Periodically check that all the nuts and screws are tightened
securely. Check that the cam-lock that controls the telecoping
pole is intact and in proper working order.
