1Introduction
Thank you for your purchase. The information contained in
this manual will help you receive maximum performance and
satisfaction from your STIHL garden pruner and, if followed,
reduce the risk of injury from its use.
SAVE THIS MANUAL!
Because a garden pruner is a high-speed, fastcutting power tool, special safety precautions
must be observed to reduce the risk of personal
injury.
Read this instruction manual thoroughly before
use and periodically thereafter. Follow all safety
precautions. Careless or improper use of the
garden pruner can cause serious or fatal injury.

to operate your garden pruner. All safety precautions that
are generally observed when working with an axe or a hand
saw also apply to the operation of garden pruners. Observe
all applicable federal, state and local safety regulations,
standards and ordinances.
Do not lend or rent your garden pruner without this
instruction manual. Allow only persons who have the proper
training and fully understand the information in this manual
to operate the garden pruner.
Your garden pruner comes with a bottle of
STIHL Multioil Bio. Use it or an equivalent, biodegradable
multifunction oil to lubricate the bar and chain. See product

5 General Power Tool Safety Warnings
To reduce the risk of personal injury or property
damage from a short circuit, fire or explosion,
keep the battery dry. Protect it from rain, water,
liquids and damp conditions. Never immerse the
battery in water or other liquids, @ 7.
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,
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.

5 General Power Tool Safety Warnings
English
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 n ot force the power tool. Use the corre ct power tool for
your application. The correct power tool will do the job
better and safer at the rate for which it was designed.
b)Do not use the power tool if the switch does not turn it on
and off. Any power tool that cannot be controlled with the
switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or remove
the battery pack, if detachable, from the power tool before
making any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce the
risk of starting the power tool accidentally.
d)Store idle power tools out of the reach of children and do
not allow persons unfamiliar with the power tool or these
instructions to operate the power tool. Power tools are
dangerous in the hands of untrained users.
e)Maintain power tools and accessories. Check for
misalignment or binding of moving parts, breakage of
parts and any other condition that may affect the power
tool's operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to
bind and are easier to control.
g)Use the power tool, accessories and tool bits etc. in
accordance with these instructions, taking into account
the working conditions and the work to be performed. Use
of the power tool for operations different from those
intended could result in a hazardous situation.
h)Keep handles and grasping surfaces dry, clean and free
from oil and grease. Slippery handles and grasping
surfaces do not allow for safe handling and control of the
tool in unexpected situations.

– Bystanders, especially children, and animals should
not be allowed in the area where the garden pruner
is in use.
￭ Prolonged use of a garden 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 garden pruner well maintained. An
improperly maintained garden pruner or one with

8 Charger Safety
English
– Do not operate a charger that has received a sharp
or heavy blow, has been dropped or is otherwise
damaged in any way.
– Do not attempt to repair, open or disassemble the
charger. There are no user-serviceable parts inside.
￭ To reduce the risk of electric shock or fire from a short
circuit:
– Make sure the battery and charger are completely
dry before starting the charging process.
– Never bridge the contacts of the charger with wires
or other metallic objects.
– Do not insert any objects into the charger's cooling
slots.
￭ The charger heats up during the charging process. To
reduce the risk of fire:
– Do not operate on a combustible surface (e.g.,
paper, cardboard, textiles) or in a combustible
environment.
– Allow the charger to cool down normally. Do not
cover it.
￭ Chargers can produce sparks which may ignite
combustible gases, liquids, vapors, dusts or other
combustible materials. To reduce the risk of fire and
explosion:
– Do not operate in a location where combustible
gases, liquids, vapors, dusts or other combustible
materials are present.
￭ Using a damaged power supply cord or plug may result in
fire, electric shock and other personal injury or property
damage. To reduce these risks:
– Check the charger’s power supply cord
and plug regularly for damage. If
damaged, immediately disconnect the
plug from the electrical outlet.
– Have a damaged power supply cord replaced by an
authorized STIHL servicing dealer.
– Unplug the power supply cord from the outlet when
the charger is not in use.
– Never jerk the power supply cord to disconnect it
from the electrical outlet. To unplug, grasp the plug,
not the power supply cord.
– Do not use the power supply cord for carrying or
hanging up the charger.
– Make sure the power supply cord is located or
marked so that it will not be stepped on, tripped over,
come in contact with sharp objects or moving parts,
or otherwise be subjected to damage or stress.
￭ An extension cord should not be used unless absolutely
necessary. Overloading an extension cord can result in
overheating and fire. If an extension cord must be used:
– Use only a properly wired 16 gauge (AWG 16) or
heavier gauge extension cord and the cord length
should not exceed 75 ft.
