tired or under the influence of drugs, alcohol, or medica­tion. A moment of inattention while operating power tools
may result in serious personal injury.

 Do not operate in poor lighting.
Do not overreach. Keep proper footing and balance at all

times. Proper footing and balance enables better control
of the tool in unexpected situations.

 Keep all parts of your body away from any moving part.
 Inspect unit before each use for loose fasteners and

damaged or missing parts. Correct before using the
attachment. Failure to do so can cause serious injury.

 Use only original manufacturer’s replacement parts.

Failure to do so may cause poor performance, possible
injury, and will void your warranty.

 Do not, under any circumstance, use any attachment or

accessory on this product, which was not provided with
the product, or identified as appropriate for use with this
product in the operator’s manual.

 Avoid dangerous environments. Do not use the attach-

ment in damp or wet locations. Do not use in rain.

 Use the right attachment. Do not use attachment for any

job except that for which it is intended.

 Keep hands away from cutting area. Keep hands away

from blades. Do not reach underneath work or around
or over the blade while blade is rotating. Do not attempt
to remove cut material when blade is moving.

 Blade coasts after being turned off.
 Do not touch areas around the muffler or cylinder of a gas

power head. These parts get hot from operation. Contact
with hot surfaces could result in possible serious personal
injury.

 Always stop the engine or motor and remove the spark

plug wire or disconnect from the power supply before
making any adjustments or repairs except for carburetor
adjustments.

WHEN USING AN ELECTRIC POWER HEAD:



Do not leave appliance when plugged in. Unplug from

outlet when not in use and before servicing.



Do not allow to be used as a toy. Close attention is nec-

essary when used by or near children.



Use only as described in this manual. Use only manufac-

turer’s recommended attachments.



Do not use with damaged cord or plug. If appliance is

not working as it should, has been dropped, damaged,
left outdoors, or dropped into water, return it to a service
center.



Do not pull or carry by cord, use cord as a handle, close a

door on cord, or pull cord around sharp edges or corners.

GENERAL SAFETY RULES



SERVICING OF DOUBLE-INSULATED APPLIANCES. A

double-insulated appliance is marked with one or more
of the following: The words “DOUBLE INSULATION” or
“DOUBLE INSULATED” or the double insulation symbol
(square within a square). In a double-insulated appli­ance, two systems of insulation are provided instead of
grounding. No grounding means is provided on a double-

SPECIFIC SAFETY RULES

insulated appliance, nor should a means for grounding
be added to the appliance. Servicing a double-insulated
appliance requires extreme care and knowledge of the
system, and should be done only by qualified service
personnel. Replacement parts for a double-insulated
appliance must be identical to the parts they replace.

Kickback is a dangerous reaction that can lead to serious

injury. Kickback may occur when the moving chain con­tacts an object at the upper portion of the tip of the guide
bar or when the wood closes in and pinches the chain
in the cut. Contact at the upper portion of the tip of the
guide bar can cause the chain to dig into the object and
stop the chain for an instant. The result is a lightning fast,
reverse reaction which kicks the guide bar up and back
toward the operator. If the chain is pinched along the top
of the guide bar, the guide bar can be driven rapidly back
toward the operator. Either of these reactions can cause
loss of tool control which can result in serious injury. Do
not rely exclusively upon the safety devices built into the
tool. As a pruner user, you should take several steps to
keep your cutting jobs free from accident or injury.

With a basic understanding of kickback, you can reduce

or eliminate the element of surprise. Sudden surprise
contributes to accidents.

Make sure that the area in which you are cutting is free

from obstructions. Do not let the nose of the guide bar
contact a log, branch, fence, or any other obstruction
while you are operating the unit.

Always cut with the engine or motor running at full speed.

Fully squeeze the trigger and maintain a steady cutting
speed.

Follow the sharpening and maintenance instructions for

the chain.

Use only the replacement guide bars and low kickback

chains specified for this unit.

Do not force tool. Use the correct tool for your applica-

tion. The correct tool will do the job better and safer at
the rate for which it is designed.

 Do not use on a ladder or unstable support. Stable foot-

ing on a solid surface enables better control of the tool
in unexpected situations.

Never let anyone use the tool who has not received

adequate instructions in its proper use. This applies to
rentals as well as privately owned units and also to the

power head it is attached to.

To protect yourself from electrocution, do not operate

within 50 ft. of overhead electrical lines.

To protect yourself from falling branches, do not stand di-

rectly under the branch or limb being cut. This unit should
not be held at an angle over 60° from ground level.

Keep the handles dry, clean, and free of oil or fuel mix-

ture.

Before you start the engine or motor, make sure the chain

is not contacting any object.

Shut off the engine or motor and make sure the cutting

attachment has stopped before setting the unit down.

DANGER! Serious injury or death from electrocution if

power lines are contacted. Never use near any electrical
source, wires, or powerlines.

Wear face shield and hard hat to protect against falling

debris. Always have a clear work area and retreat path.
Be aware of limb/branch location to avoid falling limbs
and debris. Keep bystanders 50 feet away when operat­ing saw.

Store Idle Appliance Indoors — When not in use, product

should be stored indoors in a dry and high or locked up
place—out of the reach of children.

 Save these instructions. Refer to them frequently and

use them to instruct others who may use this tool.
If you loan someone this tool, loan them these in­structions also to prevent misuse of the product and
possible injury.

NOTE: SEE YOUR POWER HEAD OPERATOR’S MANU­AL FOR ADDITIONAL SPECIFIC SAFETY RULES.

APPLICATIONS

You may use this product for the purposes listed below:

 Limbing
 Pruning

PREPARATION FOR CUTTING

 Wear non-slip gloves for maximum grip and protection.
 Maintain a proper grip on the unit whenever the engine

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

 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.

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

support the pruner.

 Be certain the knob is fully tightened before operating

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

BASIC CUTTING PROCEDURE

See Figures 5 - 6.

Follow these steps to prevent damage to tree or shrub
bark. Do not use a back-and-forth sawing motion.

 Fully squeeze the trigger and allow the engine or motor

to come to full speed just before entering the cut. Keep
the engine or motor at full speed the entire time you are
cutting.

7 — English

OPERATION

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

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

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

from the first cut.

 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 or motor can result.

 Release the trigger as soon as the cut is completed, al-

lowing the engine or motor to stop. If you run the pruner
at full speed without a cutting load, unnecessary wear or
damage can occur to the chain, bar, and engine or motor.

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:

 Stop the engine or motor.
 Remove the spark plug wire or disconnect from the power

supply.

 Loosen the knob on the coupler.
 Depress the button on the shaft; twist and pull the shafts

to separate the pruner from the power head.

 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.

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

sistance.

 Check the chain tension frequently when operating the

unit. Refer to Chain Tension in the Maintenance section
of this manual.

LIMBING AND PRUNING

See Figures 7 - 8.

This unit is designed for trimming small branches and limbs
up to 6 in. in diameter. For best results, observe the follow­ing precautions:

 Plan the cut carefully. Be aware of the direction in which

the branch will fall.

 Branches may fall in unexpected directions. Do not stand

directly under the branch being cut.

 The most typical cutting application is to position the unit

at an angle of 60° or less, depending on the specific situa­tion. As the angle of the pruner shaft to ground increases,
the difficulty of making the first cut (from the underside
of limb) increases.

 Remove long branches in several stages.
 Cut lower branches first to allow the top branches more

room to fall.

 Work slowly, keeping both hands on the tool with a firm

grip. Maintain secure footing and balance.

 Keep the tree between you and the chain while limbing.

Cut from side of tree opposite branch you are cutting.

 Do not cut from a ladder, rooftop, or other unstable sup-

port; this is extremely dangerous. Hire a professional for
complex cutting situations.

 Do not make the flush cut next to the main limb or trunk

until you have cut off the limb further out to reduce the
weight. Following proper cutting procedures will prevent
stripping the bark from the main member.

 Do not use the pruner for felling or bucking.
 To prevent electrocution, do not operate within 50 ft. of

overhead electrical lines.

 Keep bystanders at least 50 ft. away.

POSITION FOR STARTING

See Figure 9.

Lay the pruner on the ground and ensure that no objects or
obstructions are in the immediate vicinity. Make sure noth­ing can come in contact with the bar and chain, including
dirt on the ground.

bar tip, in the direction of the chain rotation.

Replace the drive case cover and reinstall the bar nut.

Tighten the bar nut finger tight only; the bar must be free
to move for tension adjustment.

Remove all slack from chain by turning the chain tension-

ing screw clockwise, assuring that the chain seats into
the bar groove during tensioning.

Lift the tip of the bar up to check for sag. Release the tip

of the bar, and turn the chain tensioning screw 1/2 turn
clockwise. Repeat this process until sag does not exist.

Hold the tip of the bar up and tighten the bar nut securely.
Chain is correctly tensioned when there is no slack on

the underside of the bar and the chain is snug, but can
be turned by hand without binding.

NOTE: If chain is too tight, it will not rotate. Loosen the

bar nut slightly and turn adjusting screw 1/4 turn counter­clockwise. Lift the tip of the bar up and retighten bar nut.

WARNING:

Only the parts shown on the parts list are intended to be
repaired or replaced by the customer. All other parts should
be replaced at an authorized service center.

WARNING:

To avoid possible serious injury, never touch or adjust
the chain while the motor is running. The chain is very
sharp; always wear protective gloves when performing
maintenance to the chain.

Check the chain tension frequently when operating the
unit. Never touch or adjust the chain while the engine or
motor is running. The chain is very sharp; always wear
protective gloves when performing maintenance to the
chain.

POWER HEAD IDLE SPEED ADJUSTMENT
(GAS POWER HEADS ONLY)

If the chain turns at idle, the idle speed screw needs adjusting
on your gas power head engine. Turn the idle speed screw
counterclockwise to reduce the idle RPM and stop the chain
movement. Refer to your power head Operator’s Manual for
more details. If the chain still moves at idle speed, contact
a service dealer for adjustment and discontinue use until
the repair is made.

MAINTENANCE

WARNING:

The chain should never turn at idle when using a gas
power head. Turn the idle speed screw “T” counter­clockwise to reduce the idle RPM and stop the chain, or
contact a service dealer for adjustment and discontinue
use until the repair is made. Serious personal injury may
result from the chain turning at idle.

CHAIN TENSION

See Figures 16 - 17.

Stop the engine or motor and remove the spark plug

wire or disconnect from power supply before setting the
chain tension. Make sure the guide bar nut is loose to
finger tight, turn the chain tensioning screw clockwise to
tension the chain. Refer to Replacing the Bar and Chain
for additional information.

A cold chain is correctly tensioned when there is no slack

on the underside of the guide bar and the chain is snug,
but can be turned by hand without binding.

The chain must be re-tensioned whenever the flats on

the drive links hang out of the bar groove.

During normal operation, the temperature of the chain will

increase. The drive links of a correctly tensioned warm
chain will hang approximately .050 in. (1.25 mm) out of
the bar groove.

NOTE: New chains tend to stretch; check chain tension

frequently and tension as required.

CHAIN MAINTENANCE

See Figure 19.

WARNING:

The chain is very sharp; always wear protective gloves
when performing maintenance to the chain.

Use only the replacement low kickback chain specified for
this unit.

For smooth and fast cutting, the chain needs to be main­tained properly. The chain requires sharpening when the
wood chips are small and powdery, the chain must be
forced through the wood during cutting, or the chain cuts
to one side. During maintenance of the chain, consider the
following:

Improper filing angle of the side plate can increase the

risk of a severe kickback.

Depth gauge (or raker clearance) setting determines the

height the cutter enters the wood and the size of the wood
chip that is removed. Too much clearance increases the
potential for kickback. Too little clearance decreases the
size of the wood chip thus decreasing the chain’s cutting
ability.

If cutter teeth have hit hard objects such as nails and

stones, or have been abraded by mud or sand on the
wood, have service dealer sharpen chain.

HOW TO SHARPEN THE CUTTERS

See Figures 20 - 23.

CAUTION:

A chain tensioned while warm may be too tight upon
cooling. Check the “cold tension” before next use.

CHAIN OILER

See Figure 18.

Use Premium Bar and Chain Lubricant. It is designed for

chains and chain oilers and is formulated to perform over
a wide temperature range with no dilution required.

Remove the cap and carefully pour approximately 8 oz.

of the bar and chain lubricant into the chain oiler tank.

Replace the cap and tighten securely.
Check and refill the chain oiler tank every hour when using

an electric power head or every time the engine is fueled
when using a gas power head.

NOTE: Do not use dirty, used, or otherwise contaminated

lubricants. Damage may occur to the oil pump, bar, or
chain.

WARNING:

Improper chain sharpening increases the potential of
kickback. Failure to replace or repair damaged chain can
cause serious injury.

Be careful to file all cutters to the specified angles and to
the same length, as fast cutting can be obtained only when
all cutters are uniform.

Tighten the chain tension enough that the chain does not

wobble. Do all of your filing at the mid-point of the bar.
Wear gloves for protection.

Use a 5/32 in. diameter round file and holder.
Keep the file level with the top plate of the tooth. Do not

let the file dip or rock.

Using light but firm pressure, stroke towards the front

corner of the tooth. Lift file away from the steel on each
return stroke.

Put a few firm strokes on every tooth. File all left hand

cutters in one direction. Then move to the other side and
file the right hand cutters in the opposite direction. Oc­casionally remove filings from the file with a wire brush.
