Keep children, bystanders, and ani
mals a minimum of 50 feet (15 me
ters) away from the work area. Do
not allow other people or animals to
be near when starting or operating
the pruner.
HAZARD ZONE
A DANGER: Do not
use near electrical
wires or power lines.
Keep pruner at least
30 feet (10 meters)
away from all power
lines.
• Do not handle or operate a pruner
when you are fatigued, ill, or upset,
or if you have taken alcohol, drugs,
or medication. You must be In good
physical condition and mentally
alert. If you have any condition that
might be aggravated by strenuous
work, check with doctor before oper
ating a pruner.
• Carefully plan your pruning operation
in advance. Do not start cutting until
you have a clear work area, secure
footing, and a planned retreat path.
FUEL SAFETY (for gas powerheads)
• Mix and pour fuel outdoors.
• Keep away from sparks or flames.
• Use a container approved for fuel.
• Do not smoke or allow smoking near
fuel or the powerhead.
• Avoid spiliing fuel or oil. Wipe up all
fuel spills before starting the power-
head.
• Move at least 10 feet (3 meters) away
from fueling site before starting power-
head engine.
• Stop engine and allow to cool before
removing fue! cap.
• Remove fuel cap slowly.
ELECTRICAL SAFETY (for electric
powerheads)
^WARNING: Avoid a dangerous
environment. To reduce the risk of elec
trical shock, do not use in rain, in damp
or wet locations, or around swimming
pools, hot tubs, etc. Do not expose to
snow, rain, or water to avoid the possi
bility of eiectrical shock. Do not use on
wet surfaces. Do not handle extension
cord plug or unit with wet hands.
• Use only a voltage supply as shown
on the nameplate of the unit.
Page 4
Avoid dangerous situations. Do not
use in presence of flammable liquids
or gases to avoid creating a fire or
explosion and/or causing damage to
unit.
Avoid dangerous environments. Do
not use in unventilated areas or
where dust or explosive vapors can
build up.
To reduce the risk of electric shock,
the powerhead may have a polarized
plug (one blade is wider than the oth
er); if so, it will require the use of a po
larized extension cord. The appliance
plug will fit into a polarized extension
cord only one way. If the plug does
not fit fully into the extension cord, re
verse the plug. If the plug still does
not fit, obtain a correct polarized ex
tension cord. A polarized extension
cord will require the use of a polarized
wall outlet. This plug will fit into the po
larized wall outlet only one way. If plug
does not fit fully into the wall outlet,
reverse the plug. If it stiil does not fit,
contact a qualified electrician to install
the proper wall outlet. Do not change
the equipment plug, extension cord
receptacle, or extension cord plug in
any way.
To reduce risk of electrical shock, use
extension cords specifically marked
as suitable for outdoor appliances
having electrical rating not less than
the rating of unit. Cord must be
marked with suffix “W-A” (in Canada
‘W’). Make sure your extension cord
is in good condition. Inspect extension
cord before use and replace if dam
aged. Do not use a damaged cord.
Cord insulation must be intact with no
cracks or deterioration. Plug connec
tors must be undamaged. The exten
sion cord used to reach the power
source must be heavy enough to
carry current from the power source
the full length of the extension cord to
the unit. An undersized extension
cord will cause a drop in line voltage
resulting in loss of power and over
heating. If in doubt, use the next
heavier gauge. The lower the gauge
number, the heavier the cord.
Do not use multiple cords.
Do not abuse cord. Never carry the
unit by the extension cord or yank
extension cord to disconnect unit. To
unplug, grasp the plug, not the cord.
Do not use cord as a handle, close a
door on cord, or pull cord around
sharp edges or corners. Do not ex
pose cords to heat, oil, or water.
• Keep the extension cord clear of op
erator and obstacles at all times.
• Tie cord to cord retainer and con
nect to recessed plug as shown in
this manual to prevent damage to
unit and/or extension cord and to re
duce the possibility of the extension
cord disconnecting from the unit dur
ing operation.
• Do not attempt to repair unit. Inspect
the insulation and connectors on the
powerhead and extension cord before
each use. If there is any damage, do
not use until damage is repaired by
your authorized service dealer.
• Do not use the powerhead if the
switch does not turn the unit on and
off properly. Have the unit repaired
by your authorized service dealer.
• Do not use with damaged cord or
plug. If powerhead is not working as
it should, has been dropped, dam
aged, left outdoors, or dropped into
water, return it to your authorized ser
vice dealer for repair.
• Avoid unintentional starting of the
unit. Never carry unit with your finger
on the switch. Be sure the switch is
in the OFF position and never touch
the switch when connecting exten
sion cord.
• Unplug the unit from the power
source when not in use, before servic
ing, and when changing accessories
and/or attachments.
• Avoid any body contact with any
grounded conductor, such as metal
fences, or pipes, to avoid the possi
bility of electric shock.
• Ground Fault Circuit Interrupter
(GFCI) protection should be pro
vided on the circuit or outlet to be
used for the powerhead. Recep
tacles are available having built-in
GFCi protection and may be used
for this measure of safety.
UNIT/MAINTENANCE SAFETY
WARNING; Disconnect power-
head spark plug (or disconnect powerhead 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.
Page 5
• Use only recommended CraftsmanCS)
parts and accessories.
• Be sure chain stops moving when
engine idles {see CARBURETOR AD
JUSTMENT section of powerhead
manual).
• Keep others away when making car
buretor adjustments.
• Never start the unit with the clutch
housing removed. The clutch can fly
off and cause serious injury.
• Keep the handles driy, clean, and free
of oil or fuel mixture.
• Keep fuel and oil caps, screws, and
fasteners securely tightened.
• Have all maintenance and service not
explained in this manual performed by

OPERATE YOUR PRUNER 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 (10 cm) 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 is completed.
• 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.
KICKBACK
idk 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 doses in and pinches
the chain in the cut. Contacting a for
eign object in the wood can aiso 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
moving chain in the cut along the
top of the guide bar and the chain is
suddenly stopped. This sudden
stopping of the chain results in a re
versal of the chain force used to cut
wood and causes the pruner to
move in the opposite direction of the
chain rotation. The pruner is driven
straight back toward 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 couid easily
cause the operator to lose control of
the pruner.
REDUCE THE CHANCE OF
KICKBACK
• Recognize that kickback can hap
pen. With a basic understanding of
kickback, you can reduce the ele
ment of surprise which contributes to
accidents.
Page 6
• 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
nate or avoid any obstruction that
your chain could hit while you are
cutting. When cutting a branch, do
not let the guide bar contact branch
or other objects around it.
• Keep your chain sharp and properly
tensioned. A loose or dull chain can
increase the chance of kickback oc
curring. Follow manufacturer’s chain
sharpening and maintenance instruc
tions. Check tension at regular inter
vals with the engine stopped, never
with the engine running. Make sure
the bar clamp nut is securely tight
ened after tensioning the chain,
• Begin and continue cutting at full
speed. If the chain is moving at a
slower speed, there is greater
chance of kickback occurring.
• Cut one branch at a time.
• Use extreme caution when re-enter
ing a previous cut.
• Do not attempt cuts starting with the
tip of the bar (plunge cuts).
• Watch for shifting of wood or other
forces that could close a cut and
pinch or fall into chain.
• Use the Reduced-Kickback Guide
Bar and Low-Kickback Chain speci
fied for your unit,
MAINTAIN CONTROL
around the throttle handle whether
your are right handed or left handed.
• Stand with your weight evenly bal
anced on both feet.
• 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
The 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.

BAR AND CHAIN LUBRICATION
The bar and chain require lubrication.
The chain oiler provides continuous
lubrication to the chain and guide bar.
Be sure to fill the bar oil tank before
use (Capacity = 4.6 fl. oz./136 ml).
Lack of oil will quickly ruin the bar and
chain. Too little oil will cause over
heating shown by smoke coming from
the chain and/or discoloration of the
bar. For maximum guide bar and
chain life, we recommend you use
Craftsman'® chain saw bar oil. If
Craftsman bar oil is not available, you
may use a good grade SAE 30 oi! until
you are able to obtain Craftsman
brand. The oil output is automatically
metered during operation.
• Never use waste oil for bar and
chain lubrication.
• Always stop the engine before re
moving the oil cap.

PRUNING
A WARNING: Be alert for and
guard against kickback. Do not allow
the moving chain to contact any other
branches or objects at the nose of the
guide bar when pruning. Allowing such
contact can result in serious injury.
IMPORTANT POINTS
• Work slowly keeping both hands
firmly gripped on the pruner. Main
tain secure footing and balance.
• Plan cut carefully. Check direction
branch will fall.
• Watch out for springpoles. Springpoles are small size limbs which can
catch the chain and whip toward you
or pull you off balance. Use extreme
caution when cutting small size limbs
or slender material.
10
Page 11
• Watch out for branches immediateiy
behind the branch being pruned. If
the chain hits the rear branch, dam
age to the unit may occur.
• Be alert for springback. Watch out
for branches that are bent or under
pressure. Avoid being struck by the
branch or the pruner when the ten
sion in the wood fibers is released.
• Keep a clear work area. Frequently
clear branches out of the way to
avoid tripping over them.
• Long branches should be removed
in several pieces.
PRUNING TECHNIQUE
When ready to cut, accelerate to full
throttle and apply a light cutting pres
sure. DO NOT use back and forth
sawing action.
Coliar
1. Make the first cut 6 inches {15 cm)
from the tree trunk on the bottom
of the limb. Use top of guide bar
to make this cut. Cut 1/3 through
the diameter of the limb.
NOTE: When making the second and
third cuts, rest the foot of the pruner
against the tree limb that is being cut
to prevent whipping of the branch.
Next, move 2-4 inches (5-10
cm) farther out on the limb and
make a second cut all the way
through the limb.
Then, make a final cut leaving a 1
- 2 inch (2.5 - 5 cm) collar from
the trunk of the tree to avoid dam
age to the tree.

if chain does not rotate, it is too
tight. Slightly loosen bar clamp nut
and loosen chain by turning the ad
justing screw 1/4 turn counterclock
wise. Retighten bar clamp nut.
9. If chain is too loose, it will sag below
the guide bar and needs to be tight
ened following above procedure.
^WARNING; DO NOT operate the
pruner if the chain is loose. If the pruner is operated with a loose chain, the
chain could jump off the guide bar and
result in serious injury.
CHECK CHAIN SHARPNESS
A sharp chain makes wood chips. A
dull chain makes a sawdust powder
and cuts slowly. See CHAIN SHARP
ENING in the SERVICE AND ADJUST
MENTS section.
BAR MAINTENANCE
If your pruner cuts to one side, has to
be forced through the cut, or been run
with an improper amount of bar lubri
cation it may be necessary to service
your bar. A worn bar will damage your
chain and make cutting difficult.
After each use, ensure ON/OFF switch is
in the OFF position, then dean all saw
dust from the guide bar and sprocket
hole.
To maintain guide bar:
• Move ON/OFF switch to the OFF posi
tion and disconnect spark plug {or dis
connect powerhead from power
source).
• Loosen and remove bar clamp nut
and chain brake. Remove bar and
chain from pruner.
• Clean the oil holes and bar groove
after each 5 hours of operation.
Remove Sawdust From
Guide Bar Groove
Burring of guide bar rails is a normal
process of rail wear. Remove these
burrs with a flat file.
When rail top is uneven, use a flat
file to restore square edges and
sides.
