OPERATION

WARNING:

Do not allow familiarity with tools to make you care-
less. Remember that a careless fraction of a second is
sufficient to inflict serious injury.

WARNING:

Always wear safety goggles or safety glasses with
side shields, a hard hat, and safety shoes when
operating tools. Failure to do so could result in
objects being thrown into your eyes, resulting in
possible serious injury.

WARNING:

Do not use any attachments or accessories not rec-
ommended by the manufacturer of this tool. The use
of attachments or accessories not recommended can
result in serious personal injury.

WARNING:

To avoid kickback, binding of the saw bar, and possible
injury, never cut limbs that the pruner does not reach
when supported by the shoulder strap.

PREPARATION FOR PRUNER CUTTING

See Figures 6 - 7.
n

Wear non-slip gloves for maximum grip and protection.

�n Maintain a proper grip on the unit whenever the engine is

running. Use your right hand to firmly grip the rear handle
while your left hand has a firm grip on the front handle.

�n Hold unit firmly with both hands. Always keep your left

hand on the front handle and your right hand on the rear
handle, so your body is to the left of the chain line. Never
use a left-handed (cross-handed) grip, or any stance that
places your body or arm across the chain line.

�n Never stand directly under the limb you are cutting.
�n Always wear shoulder strap for increased safety and to

support the pruner.

n

Be certain the knob is fully tightened before operating

equipment; check it periodically for tightness during use
to avoid serious injury.

BASIC CUTTING PROCEDURE
Follow the steps below to prevent damage to tree or shrub
bark. Do not use a back-and-forth sawing motion.
n

Accelerate the engine to full throttle just before entering

the cut by squeezing the throttle trigger. Keep the engine
at full throttle the entire time you are cutting.

n

Make a shallow first cut (1/4 of limb diameter) on the

underside of the limb close to the main limb or trunk.

n

Make a second cut from the top side of the limb outboard

from the first cut.

n

Make a final cut close to trunk.

NOTE: For second and final cuts (from top of limb or branch),
hold front cutting guide against the limb being cut. This will
help steady the limb and make it easier to cut. Allow chain to
cut for you; exert only light downward pressure. If you force
the cut, damage to the bar, chain, or engine can result.

LOAD

n

Release the trigger as soon as the cut is completed, allow-

ing the engine to idle. If you run the pruner at full throttle
without a cutting load, unnecessary wear or damage can
occur to the chain, bar, and engine.

CUTTING GUIDE

Fig. 7

Failure to follow proper cutting procedures will result in the
bar and chain binding and becoming pinched or trapped in
the limb. If this should happen:
n

Stop the engine.

n

Loosen the knob on the coupler.

n

Depress the button on the shaft; twist and pull the shafts

to separate the pruner from the power head.

n

If the limb can be reached from the ground, lift the limb

while holding the attachment. This should release the
“pinch” and free the pruner.

n

If the pruner is still trapped, call a professional for as-

sistance.
