Pruning
Pruning is the process of trimming limbs from a live tree.
• Remove long branches in several stages.
• Cut lower branches first to allow the top branches more
room to fall.
• When pruning trees, it is important not to make the
finishing cut next to the main limb or trunk until you have
cut off the farthest lying limb. This will reduce the weight
and prevent stripping the bark from the main member.
• Under cut the branch 1/3 through for your first cut.
Your second cut should over cut to drop the branch off
(Fig. 27). Be prepared to balance the weight of the pole
chain saw when the limb falls.

• When re-starting the motor, always keep the ON/Off
trigger switch pressed.
NOTE: The motor only runs when the ON/Off trigger
switch is operated and shuts off when the ON/Off trigger
switch is released.
• Now make your finishing cut from the topside of the
branch smoothly and neatly against the main member so
the bark will grow back to seal the wound.
• Release the On/Off trigger switch as soon as the cut is
completed. Failure to follow proper cutting procedures will
result in the bar and chain binding and becoming pinched
or trapped in the limb.
Limbing
Limbing is the process of removing branches from a fallen tree.
• You should cut limbs one at a time. Remove the cut limbs
from the work area often to help keep the work area clean
and safe.
• Cut branches under tension from the bottom up to avoid
binding the bar and chain.
• 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, remove the battery, 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.

Maintenance + Care

m
WARNING!
Always remove the battery before
performing any adjustments, maintenance, or repairs to your
cordless 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.

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. 27). 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.
