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.

English
5 General Power Tool Safety Warnings
￭ 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,
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

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

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.

– 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:

7 Kickback and Other Reactive Forces
– 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
￭ 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
– Pull-in
– Pushback
7.2 Kickback
7.2.1 Kickback
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.
20
0000097293_001
WARNING
￭ Kickback may occur when the moving chain near the
upper quadrant of the bar nose contacts a solid object or
is pinched.
0458-191-8621-A
7 Kickback and Other Reactive Forces
0000-GXX-1348-A0
0000-GXX-1349-A0
English
￭ 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.
7.2.2 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.
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
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.
7.4 Pushback
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.
