UNIT/MAINTENANCE SAFETY

_IWARNING: Disconnect power-

head spark plug (or disconnect power-
head from power source) before per-

forming maintenance.

• Inspect entire unit before each use.
Replace damaged parts. Check for

fuel leaks. Make sure all fasteners are
in place and securely fastened.

• Maintain unit according to recom-
mended procedures.

• Use only recommended Craftsman(R_
parts and accessories. Never usewire,

wire rope, string, flailing devices, etc.

• Be sure chain stops moving when en-
gine idles (see CARBURETOR ADJUST-

MENT section of powerhead manual).

• Keep others away when making car-
buretor adjustments.

OPERATEYOURPRUNER SAFELY

• Do not operate a pruner with one
hand. Serious injury to the operator,

helpers, bystanders or any combina-
tion of these persons may result

from one-handed operation. A prun-
er is intended for two-handed use.

• Operate the pruner only in a well-ven-
tilated outdoor area.

• Do not operate pruner from a ladder
or in a tree.

• Do not use a pruner to cut down trees
or any portion of the tree trunk.

• Only use for pruning limbs or
branches overhead not greater than 4

inches in diameter.

• Never stand under the limb you are
pruning. Always position yourself out

of the path of falling debris.

• Do not cut small brush and saplings
with the pruner. Slender matter may

catch in the chain and be whipped to-
ward you, pulling you off balance.

• Make sure the chain will not make
contact with any object while starting

the engine. Never try to start the unit
when the guide bar is in a cut.

• Do not put pressure on the pruner at
the end of the cut. Applying pressure

can cause you to lose control when
the cut iscompleted.

• Do not run the unit at high speed
when not pruning.

• If you strike or become entangled with
a foreign object, stop the engine im-

mediately and check for damage.
Have any damage repaired by a

Sears Service Center before attempt-
ing further operations.

• Do not operate a pruner that is dam-
aged, improperly adjusted, or not

completely and securely assembled.
Always replace bar and chain immedi-

ately if it becomes damaged, broken
or is otherwise removed.

• Always stop the unit when work is
delayed or when walking from one

cutting location to another. Stop the
engine before setting the unit down.

• Use only in daylight or good artificial
light.

• Use only for jobs explained in this
manual (or manuals for optional at-

tachments).

KICKBACK

,_WARNING: Avoid kickback
which can result in serious injury.

Kickback is the backward, upward or

sudden forward motion of the guide

bar occurring when the chain near the

upper tip of the guide bar contacts any
object such as a log or branch, or
when the wood closes in and pinches

the chain in the cut. Contacting a for-
eign object in the wood can also result

in loss of control.

• Rotational Kickback can occur when
the moving chain contacts an object

at the upper tip of the guide bar. This
contact can cause the chain to dig

into the object, which stops the chain
for an instant. The result is a lightning

fast, reverse reaction which kicks the
guide bar up and back toward the op-

erator.

• Pinch-Kickback can occur when the
wood closes in and pinches the mov-

ing chain in the cut along the top of
the guide bar and the chain is sud-
denly stopped. This sudden stopping

of the chain results in a reversal of the
chain force used to cut wood and

causes the pruner to move in the op-
posite direction of the chain rotation.
The pruner is driven straight back to-

ward the operator.

• Pull-In can occur when the moving
chain contacts a foreign object in the

wood in the cut along the bottom of
the guide bar and the chain is sud-

denly stopped. This sudden stopping
pulls the pruner forward and away

from the operator and could easily
cause the operator to lose control of

the pruner.

REDUCE THE CHANCE OF
KICKBACK

• Recognize that kickback can happen=
With a basic understanding of kick-

back, you can reduce the element of
surprise which contributes to acci-

dents.

• Never let the moving chain contact
any object at the tip of the guide bar.

• Keep the working area free from ob-
structions such as other trees,
branches, rocks, stumps, etc. Elimi-

MAINTAIN CONTROL

• Stand slightly to the left side of the
pruner to keep your body from being
in a direct line with the cutting chain.

KICKBACK SAFETY FEATURES

Tile following features are included on
your pruner to help reduce the hazard

of kickback; however, such features
will not totally eliminate this danger.

As a pruner user, do not rely only on
safety devices. You must follow all

safety precautions, instructions, and
maintenance in this manual to help

avoid kickback and other forces which
can result in serious injury.

• Reduced-Kickback Guide Bar, de-
signed with a small radius tip which

reduces the size of the kickback
danger zone on the bar tip.

• Keep a good, firm grip on the pruner
with both hands when the engine is

running and don't let go. A firm grip
will help you reduce kickback and

maintain control. Keep the fingers of
your left hand encircling and your

left thumb under the assist handle.
Keep your right hand completely

around the throttle handle whether
your are right handed or left handed.

• Stand with your weight evenly bal-
anced on both feet.
