GENERAL SAFETY RULES

4
SPECIFIC SAFETY RULES
 Kickback is a dangerous reaction that can lead to serious
injury. Kickback may occur when the moving chain con-
tacts 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 running at full speed. Fully
squeeze the throttle 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 private 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
directly 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, make sure the chain is not
contacting any object.
 Shut off the engine and make sure the cutting attachment
has stopped before setting the unit down.
 To prevent electrical shock or serious personal injury, do
not use this product with any AC power head.
 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 instruc-
tions also to prevent misuse of the product and
possible injury.

CUTTING GUIDE
OPERATION
WARNING:
Do not allow familiarity with tools to make you careless.
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 when operating power 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
recommended by the manufacturer of this tool. The use
of attachments or accessories not recommended can
result in serious personal injury.
APPLICATIONS
You may use this tool 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 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.
� 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.
FINAL CUT
SECOND CUT
FIRST CUT
1/4 DIAMETER
LOAD
Fig. 5
 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 can result.
 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.
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.
� 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 assis-
tance.
 Check the chain tension frequently when operating the
unit. Refer to Chain Tension in the Maintenance section
of this manual.

60° MAXIMUM
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 follow-
ing 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 situa-
tion. 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; this is extremely dangerous.
Leave this operation for professionals.
 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 noth-
ing can come in contact with the bar and chain, including
dirt on the ground.

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

CHAIN MAINTENANCE
See Figure 20.
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 21 - 24.
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. Occa-
sionally remove filings from the file with a wire brush.
