Description
Long-reach chain saws are hydraulically powered
cutting tools intended for general tree trimming from the
ground or from an aerial device.
Greenlee Utility’s patented Super Spool™ design allows
the tool to be used with either open-center or closed-
center hydraulic systems. The dielectric properties of
the berglass pole reduce the chance of electric shock
when the saw is used near energized electrical lines.
Other features include an anti-kickback chain, a fully
covered sprocket guard, a hand-stop safety collar, a
trigger interlock and a trigger guard.
Super Spool is protected by U.S. Patent No. 4,548,229.

Chain Saw Basics
This section introduces some basic principles of chain
saw use: Hazard Prevention, Compression and
Tension.
HAZARD PREVENTION
The cutting action of this chain saw is performed by a
chain-type blade driven at high speed by a powerful
hydraulic motor. When used carefully and properly, the
chain saw is a highly effective cutting tool.
When used improperly, or when anything interferes with
the normal rotation of the blade, the operator could
very suddenly and very quickly lose control of the saw.
Such loss of control can result in harm to the operator.
The three terms that describe loss of control are pull-in,
push-back, and kickback.
Pull-In
Pull-in can occur when the blade at the bottom of the
bar is doing the cutting. If the blade is suddenly pinched
in the cut, or if it contacts a foreign object such as a
nail, the saw may be suddenly and forcefully pulled
away from the operator.
Pull-In
PULL
Push-Back
Push-back can occur when the blade at the top of the
bar is doing the cutting. If the blade is suddenly pinched
in the cut, or if it contacts a foreign object such as a
nail, the saw will be suddenly and forcefully pushed
back toward the operator.
Push-Back
PUSH
Kickback
Kickback is much more hazardous than pull-in or push-
back. When kickback happens, the entire saw may
rotate suddenly and forcefully. The bar of the saw may
quickly travel upward and back, toward the operator.
Kickback can occur when the blade at the guide bar
tip contacts anything while the chain is rotating. Some
causes for kickback are:
• using the guide bar tip for cutting.
• contacting a nail or other metal object when
cutting.
• accidental contact when cutting more than one
branch at a time.

Chain Saw Basics (cont’d)
Preventing Pull-In, Push-Back and Kickback
The chain/bar combination and shroud are intended to
prevent or reduce the likelihood and severity of kick-
back. Verify that these items are in good working order
(chain is sharp and properly tensioned, shroud is not
damaged, etc.) to get the maximum benet from these
features. If worn or damaged, replace these items with
Greenlee Utility replacement parts.
General Tips:
• Maintain the saw properly. Verify that the blade is
sharp and has been properly tensioned.
• Do not allow the guide bar tip to contact anything.
• Do not over-reach.
• Do not use the saw above shoulder height.
• Cut only one limb, branch, or log at a time.
• Be aware that small-diameter limbs or branches are
more likely to catch the blade, causing pull-in or
kickback.
Verify that the chain is sharp
and properly tensioned.
Do not allow the
guide bar tip to
contact anything.
Cutting Procedure:
• Hold the chain saw securely with both hands and
maintain a rm, secure grip.
• Bring the chain saw to full rpm before starting the cut.
Maintain full rpm until the cut is completely nished.
• Apply a moderate amount of downward force to the
saw.
• Cut straight through. Do not twist the saw during the
cut.
• Be alert for the limb to shift, which may pinch the saw
in the cut.
• Be alert for a limb or branch under tension to spring
back when the cut is complete and the tension is
released.
Cutting Procedure
Apply a moderate
amount of
downward force.
Bring chain to full rpm.
Maintain full rpm until
the cut is finished.
Hold saw securely
with both hands.
