5 General Power Tool Safety Warnings
5.1 Introduction
This chapter contains the prescribed general safety
warnings and instructions for handheld, motor-operated
electric power tools. Additional important warnings and
instructions are provided in subsequent chapters of this
manual.
WARNING
￭ Read all safety warnings and all instructions. Failure to
follow the warnings and instructions may result in electric
shock, fire and/or serious injury.
￭ Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mainsoperated (corded) power tool or battery-operated (cordless)
power tool.
5.2 Work Area Safety
a)Keep work area clean and well lit. Cluttered or dark areas
invite accidents.
b)Do not operate power tools in explosive atmospheres,
such as in the presence of flammable liquids, gases or
dust. Power tools create sparks which may ignite the dust
or fumes.
c) Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
5.3 Electrical Safety
a)Power tool plugs must match the outlet. Never modify the
plug in any way. Do not use any adapter plugs with
earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce the risk of electric shock.
b)Avoid body contact with earthed or grounded surfaces,
such as pipes, radiators, ranges and refrigerators. There
is an increased risk of electric shock if your body is
earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric
shock.
d)Do not abuse the cord. Never use the cord for carrying,
pulling or unplugging the power tool. Keep cord away from
heat, oil, sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric shock.
e)When operating a power tool outdoors, use an extension
cord suitable for outdoor use. Use of a cord suitable for
outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD) or
ground fault circuit interruptor (GFCI) protected supply.
Use of an RCD or GFCI reduces the risk of electric shock.
5.4 Personal Safety
a)Stay alert, watch what you are doing and use common
sense when operating a power tool. Do not use a power
tool while you are tired or under the influence of drugs,
0458-191-8221-A
7
English
5 General Power Tool Safety Warnings
alcohol or medication. A moment of inattention while
operating power tools may result in serious personal
injury.
b)Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask, nonskid safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the
off-position before connecting to power source and/or
battery pack, picking up or carrying the tool. Carrying
power tools with your finger on the switch or energizing
power tools that have the switch on invites accidents.
d)Remove any adjusting key or wrench before turning the
power tool on. A wrench or a key left attached to a rotating
part of the power tool may result in personal injury.
e)Do not overreach. Keep proper footing and balance at all
times. This enables better control of the power tool in
unexpected situations.
f) Dress properly. Do not wear loose clothing or jewellery.
Keep your hair and clothing away from moving parts.
Loose clothes, jewellery or long hair can be caught in
moving parts.
g)If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection can
reduce dust-related hazards.
h)Do not let familiarity gained from frequent use of tools
allow you to become complacent and ignore tool safety
principles. A careless action can cause severe injury
within a fraction of a second.
5.5 Power Tool Use and Care
a)Do not force the power tool. Use the correct power tool for
your application. The correct power tool will do the job
better and safer at the rate for which it was designed.

series backpack battery in combination with an
AP Adapter.
Batteries, chargers and other accessories are sold
separately.
6.2 Operator
WARNING
￭ Working with the pole pruner can be strenuous. The
operator must be in good physical condition and mental
health. To reduce the risk of personal injury from fatigue
and loss of control:
– Check with your doctor before using the pole pruner
if you have any health condition that may be
aggravated by strenuous work.
– Do not operate the pole pruner while under the
influence of any substance (drug, alcohol or
medication, etc.) that might impair vision, balance,
dexterity or judgment.
– Be alert. Do not operate the pole pruner when you
are tired. Take a break if you become tired.
– Do not permit minors to use the pole pruner.
– Bystanders, especially children, and animals should
not be allowed in the area where the pole pruner is
in use.
￭ Prolonged use of a pole pruner (or other power tools)
exposing the operator to vibration may produce white
finger disease (Raynaud's phenomenon) or carpal tunnel
syndrome. These conditions reduce the hand's ability to
feel and regulate temperature. They produce numbness
and burning sensations and may also cause nerve and
circulation damage as well as tissue necrosis.
￭ All factors which contribute to white finger disease are not
known. Cold weather, smoking and diseases or physical
conditions that affect blood vessels and blood transport,
as well as high vibration levels and long periods of
exposure to vibration, are mentioned as factors in the
development of white finger disease.
￭ To reduce the risk of white finger disease and carpal
tunnel syndrome:
– Wear gloves while working and keep your hands
warm.
– Keep the pole pruner well maintained. An improperly
maintained pole pruner or one with loose
components will tend to have higher vibration levels.
– Keep the saw chain sharp. A dull chain will increase
cutting time, and pressing a dull chain through wood
will increase the vibration transmitted to your hands.
– Maintain a firm grip at all times, but do not squeeze
the handles with constant, excessive pressure. Take
frequent breaks.
￭ These precautions do not guarantee that you will not
sustain white finger disease or carpal tunnel syndrome.
– Closely monitor the condition of your hands and
fingers if you are a regular operator.
– Seek medical advice immediately if any of the above
symptoms appear.
￭ According to STIHL's current knowledge, the electric

0458-191-8221-A
6 IMPORTANT SAFETY INSTRUCTIONS
English
– Position the pole pruner in such a way that all parts
of your body are clear of the cutting attachment
whenever the battery is inserted. Stand to the left or
right of the cut while limbing, outside of the cutting
plane (see illustration).
– Avoid contacting any object with the upper quadrant
of the tip of the guide bar. It may cause kickback to
occur.
– Always hold the pole pruner firmly with both hands
when you are working.
– Read and follow all warnings and instructions in the
chapter Kickback and Reactive Forces, @ 7.
￭ One-handed operation makes it difficult to oppose and
absorb reactive forces (pushback, pull-in, kickback)
without losing control of the pole pruner. It also makes it
difficult to prevent the bar and chain from bouncing along
a limb. To reduce the risk of serious or fatal injury to the
operator or bystanders from loss of control:
– Never attempt to operate the pole pruner with one
hand.
￭ To reduce the risk of serious or fatal cut injuries to the
operator or bystanders from loss of control, keep proper
footing and balance at all times:
– Never work on a ladder, roof, in a tree or while
standing on any other insecure support.
– Take special care in overgrown or wet terrain and
always watch for hidden obstacles such as tree
stumps, roots, rocks, holes and ditches to avoid
stumbling or falling.
– Be extremely cautious when working on slopes or
uneven ground.
– For better footing, always clear away fallen
branches, scrub and cuttings and other material,
objects or vegetation that can increase the danger of
slipping, tripping or falling.
– Use extreme caution when cutting small-size brush,
branches and saplings because slender material
may catch the chain and spring toward you or pull
you off balance.
– Do not overreach. Keep proper footing and balance
at all times.
– Never switch on the pole pruner when the guide bar
is in a cut or kerf. Doing so could lead to reactive
forces and injury. Instead, remove the guide bar
from the cut and re-enter at full speed, taking care to
avoid contacting any object with the tip of the guide
bar.
– For a pole pruner with an adjustable shaft, expand
the shaft only as far as necessary for the intended
application, but never cut directly overhead. Ensure
that the pole pruner is positioned no more than 60°
from the horizontal plane, @ 6.5.4.
￭ Working above shoulder height can be tiring. To reduce
the risk of injury from fatigue:
– Never hold the machine with your rear hand on the
control handle above shoulder height.
– Take frequent breaks.
￭ The hook is designed to provide greater control of the pole
pruner while cutting. If you work without the hook, the pole
pruner may pull you forward suddenly. This could cause
loss of control or, if the tip of the guide bar strikes an
object, kickback.
– Always work with the hook to maintain better control
of the pole pruner.
￭ Applying pressure to the pole pruner when reaching the
end of a cut may cause the bar and rotating chain to
accelerate out of the kerf, go out of control and strike
some other object. To reduce the risk of injury:
– Use caution when approaching the end of a cut.
– Never put pressure on the pole pruner when
reaching the end of a cut.

6.5.4 Operating Instructions
WARNING
￭ To reduce the risk of severe personal injuries from
unintentional starting:
– Never touch a chain with your hand or any part of
your body when the battery is inserted, even when
the chain is not rotating.
￭ To reduce the risk of cut injuries:
– Keep hands and feet away from the saw chain.
– Never touch a moving chain with your hand or any
other part of your body.
– Always pull the unit out of the cut with the chain
running to reduce the possibility of pinching the
cutting attachment.
– If the chain becomes clogged, always switch off the
motor, remove the battery and make sure the chain
has stopped before cleaning.
– If a pinch occurs that traps the bar/chain, switch off
the motor and remove the battery before attempting
to remove the bar.
– Don't put pressure on the pole pruner when reaching
the end of a cut. The pressure may cause the bar
and rotating chain to pop out of the cut or kerf, go out
of control and strike some other object.
￭ The chain continues to move for a short period after the
trigger switch is fully released.
– Wait for the chain to stop before walking with the
pole pruner or putting it down.
￭ In the event of an emergency:
– Switch off the motor immediately and remove the
battery.
￭ Contacting foreign objects while sawing might cause the
chain to break or be thrown, or cause the pole pruner to
propel dangerous debris or kick back in the direction of the
operator. To reduce the risk of severe or fatal personal
injury caused by contact with foreign objects:
– Inspect the branch before cutting.
– Remove any foreign objects to ensure that the wood
is free of materials such as nails, spikes, cables, or
wires.
– Before starting a cut, ensure that it can be completed

6 IMPORTANT SAFETY INSTRUCTIONS
– Always keep bystanders at least
50 ft. (15 m) away when the
power tool is in use.
– Do not allow other persons in the general work area.
￭ Check the chain and guide bar at regular short intervals
during operation, or immediately if there is a change in
cutting behavior:
– Switch off the motor and remove the battery.
– Check the condition and tension of the chain. Look
for damage to the chain or guide bar.
– If the chain cannot be properly tensioned, or if other
components of the pole pruner are worn or
damaged, stop work immediately and take your pole
pruner to an authorized STIHL servicing dealer for
inspection, repair or maintenance.
￭ If a tree is rotted, it could snap and fall toward the operator
while being cut. To reduce the risk of injury from falling
debris, take the following steps before starting work:
– Observe the general condition of the tree. Inspect for
decay or rot in the trunk and branches. Look for dead
branches that could vibrate loose and fall on the
operator.
– To prevent a larger branch from splitting, make a
shallow relief cut at the bottom of the branch before
making a finishing cut from the top. This procedure
will help reduce damage to the tree and also help
make the fall of the limb more predictable.
￭
￭ To reduce the risk of severe or even fatal injury from
falling objects:
– Never cut directly overhead. Hold the pole pruner no
more than 60° from the horizontal plane (see
illustration).
– Never stand underneath the limb being cut.
– Watch for falling limbs. Objects may fall in
unexpected directions.
– Establish an escape route away from where the
limbs may fall.
– As soon as the limbed branch starts to fall, step
away and keep a sufficient distance away.
– Keep the work area clear and free of obstacles and
fallen limbs. Place all tools and equipment out of
your immediate work area and escape route.
￭ There is an increased danger of pinching the pole pruner
when cutting branches under tension. The tension in wood
can also release suddenly and with great force, propelling
the limb or pole pruner into the operator, causing injury or
loss of control.

￭
￭ To reduce the risk of severe or fatal personal injury from
loss of control when cutting wood under tension:
– Always start with a relieving cut (1) at the
compression side (A) of the branch, and then make
a cross-cut (2) at the tension side (B).
– If a pinch occurs that traps the bar/chain, switch off
the motor, remove the battery and remove the pole
pruner from the branch, exercising caution that the
limb does not suddenly snap or release.
DANGER
￭ Electricity can jump from one point to another by means of
arcing. Higher voltage increases the distance electricity
can arc. Electricity can also move through branches,
especially if they are wet. To reduce the risk of
electrocution:
– Never operate this pole pruner in the
vicinity of any wires or cables that may
be carrying electric current. Look
carefully for concealed wires before
starting work.
– Never cut near power lines.
– Hold the power tool only at the
designated gripping surfaces, but do not
rely on them for protection against
electric shock. This pruner is not
insulated.
– Maintain a clearance of at least
50 ft. (15 m) between the pole
pruner (including any branches
it is contacting) and any
electrical line carrying live
current.
– Before working with less
clearance, contact your electric
utility and make sure the current
is turned off.
7 Kickback and Other Reactive Forces
7.1 Reactive Forces
WARNING
￭ Reactive forces may occur any time the chain is rotating.
Reactive forces can cause serious or fatal personal injury.
￭ The powerful forces used to cut wood can be reversed and
work against the operator. If the rotating saw chain is
suddenly and significantly slowed or stopped by contact
with any solid object such as a branch, or is pinched, the
reactive forces may occur instantly.
￭ These reactive forces may result in loss of control, which,
in turn, may cause serious or fatal injury.
– An understanding of the causes of these reactive
forces may help you avoid the element of surprise
and loss of control. Surprise contributes to
accidents.
￭ Because of the design of the pole pruner, the reactive
forces experienced when working with it are generally not
as severe as those encountered with a chain saw.
– Nevertheless, always maintain a proper grip and
good footing to control the pole pruner when you
experience such forces.
The most common reactive forces are:
– Kickback

7 Kickback and Other Reactive Forces
– Pull-in
– Pushback
7.2 Kickback
7.2.1 Kickback
WARNING
￭ Kickback may occur when the moving chain near the
upper quadrant of the bar nose contacts a solid object or
is pinched.
￭ When this occurs, the energy driving the chain can create
a force that moves the pole pruner in a direction opposite
to the chain movement at the point where the chain is
slowed or stopped. This may cause the bar to move
upward.
7.3 Pull-in
WARNING
￭ Pull-in occurs when the chain on the bottom of the bar is
suddenly stopped or significantly slowed when it is
pinched, caught or encounters a foreign object in the
0000097293_001
wood. The reaction of the chain pulls the pole pruner
forward.
￭ Pull-in usually occurs when the chain is not rotating at full
speed before it contacts the wood.
￭ To reduce the risk of pull-in:
– Be alert to forces or situations that may cause
material to pinch the chain at the bottom of the bar.
– Always start a cut with the chain rotating at full
speed.
7.2.2 To Avoid Kickback
The best protection from personal injury that may result from
kickback is to avoid kickback situations:
1)Be aware of the location of the guide bar nose at all times.
2)Never let the nose of the guide bar contact any object. Do
not cut limbs with the nose of the guide bar. Be especially
careful near wire fences and when cutting small, tough
limbs, which may easily catch the chain.
3)Cut only one limb at a time.

8 Battery Safety
English
WARNING
￭ Pushback occurs when the chain on the top of the bar is
suddenly stopped or significantly slowed when it is
pinched, caught or encounters a foreign object in the
wood. The reaction of the chain may drive the pole pruner
rapidly straight back toward the operator.
￭ Pushback usually occurs when the top of the bar is used
for cutting.
￭ To reduce the risk of pushback:
– Be alert to forces or situations that may cause
material to pinch or bind the top of the bar.
– Do not cut more than one limb at a time.
– Do not twist the bar when withdrawing it from an
underbuck cut because the chain can pinch or bind.
