INTENDED USE
This cordless hedge trimmer is designed for cutting and trimming of hedges,
bushes and ornamental shrub in the domestic environment.
For safety reasons it is essential to read the entire instruction manual before rst
operation and to observe all the instructions.
This product is intended for private domestic use only, not for any commercial
trade use. It must not be used for any purposes other than those described.
GENERAL SAFETY WARNINGS
WARNING!
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may
result in electric shock, re and/or serious injury.
Save all warnings and instructions for future
reference.
The term “power tool” in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
Work area safety
1. Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
2. Do not operate power tools in explosive atmospheres,
such as in the presence of ammable liquids, gases
or dust. Power tools create sparks which may ignite
the dust or fumes.
3. Keep children and bystanders away while operating
a power tool. Distractions can cause you to lose
control.
Electrical safety
1. 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. Unmodied
plugs and matching outlets will reduce risk of electric
shock.
2. 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.
3. Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
4. 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.
5. 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.
6. If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk of
electric shock.
NOTE: The term “residual current device(RCD)” may
be replaced by the term “ground fault circuit interrupter
(GFCI)” or “earth leakage circuit breaker(ELCB)”
GENERAL SAFETY WARNINGS

8 9
Personal safety
1. 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
inuence of drugs, alcohol or medication. A moment
of inattention while operating power tools may result
in serious personal injury.
2. Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection
used for appropriate conditions will reduce personal
injuries.
3. 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 nger on the switch or
energising power tools that have the switch on invites
accidents.
4. 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.
5. Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations
6. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewellery or long
hair can be caught in moving parts.
GENERAL SAFETY WARNINGS GENERAL SAFETY WARNINGS
7. 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.
Power tool use and care
1. 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.
2. 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.
3. Disconnect the plug from the power source and/or
the battery pack 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.
4. 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.
5. Maintain power tools. 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.

10 11
GENERAL SAFETY WARNINGS
6. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
7. 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.
Battery tool use and care
1. Recharge only with the charger specied by the
manufacturer. A charger that is suitable for one type
of battery pack may create a risk of re when used
with another battery pack.
2. Use power tools only with specically designated
battery packs. Use of any other battery packs may
create a risk of injury and re.
3. When battery pack is not in use, keep it away from
other metal objects, like paper clips, coins, keys,
nails, screws or other small metal objects that can
make a connection from one terminal to another.
Shorting the battery terminals together may cause
burns or a re.
4. Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally
occurs, ush with water. If liquid contact eyes,
additionally seek medical help. Liquid ejected from
the battery may cause irritation or burns.
PRODUCT SAFETY WARNINGS
Service
Have your power tool serviced by a qualied repair
person using only identical replacement parts. This will
ensure that the safety of the power tool is maintained.
SPECIAL SAFETY INSTRUCTIONS FOR CORDLESS
HEDGE TRIMMER
1. Keep all parts of the body away from the cutter blade.
Do not remove cut material or hold material to be
cut when blades are moving. Make sure the switch
is off when clearing jammed material. A moment of
inattention while operating the hedge trimmer may
result in serious personal injury.
2. Carry the hedge trimmer by the handle with the cutter
blade stopped. When transporting or storing the
hedge trimmer always t the cutting device cover.
Proper handling of the hedge trimmer will reduce
possible personal injury from the cutter blades.
3. Hold the power tool by insulated gripping surfaces
only, because the cutter blade may contact hidden
wiring. Cutter blades contacting a “live” wire may
make exposed metal parts of the power tool “live”
and could give the operator an electric shock.
4. Keep cable away from cutting area. During operation
the cable may be hidden in shrubs and can be
accidentally cut by the blade.
5. Check the hedge for foreign objects before operating,
e.g. wire fences.
6. Only use the hedge trimmer with the guard properly

12 13
PRODUCT SAFETY WARNINGS
assembled. The use of the hedge trimmer without the
proper guard may result in serious personal injury!
7. Use both hands when operating the hedge trimmer.
Using one hand could cause loss of control and result
in serious personal injury.
8. Do not grasp the exposed cutting blades or cutting
edges when picking up or holding the hedge trimmer.
9. Do not use on a ladder, rooftop, tree, or other
unstable support. Stable footing on a solid surface
enables better control of the hedge trimmer in
unexpected situations.
10. Never allow children to operate the hedge trimmer.
11. Never remove or tamper with safety devices. Check
their proper operation regularly. Never do anything to
interfere with the intended function of a safety device
or to reduce the protection provided by a safety
device.
12. Never operate the hedge trimmer without proper
guards, plates, or other safety protective devices in

that may affect its operation. A guard or other part
that is damaged should be properly repaired or
replaced by an authorized service center unless
indicated elsewhere in this manual.
PRODUCT SAFETY WARNINGS
14. Check the blade and motor mounting bolts at
frequent intervals for proper tightness. Also, visually
inspect blade for damage (e.g., bent, cracked, and
worn).
15. Replace the blade if it is bent or cracked. An
unbalanced blade causes vibration that could
damage the motor drive unit or cause personal injury.
16. If the equipment should start to vibrate abnormally,
stop the motor and check immediately for the cause.
Vibration is generally a warning of trouble.
17. The trimmer shall be used to cut stems less than (20
mm) thick.
18. Trim only in daylight or in good articial light.
19. Remove or disconnect battery before servicing,
cleaning, or removing material from the hedge
trimmer.
20. Do not wash with a hose; avoid getting water in
motor and electrical connections.

listed in this manual. Use of parts which do not meet
the original equipment specications may lead to
improper performance and compromised safety.
22. Follow instructions for lubricating and changing
accessories.
23. Keep handles dry, clean and free from oil and grease.
24. Save these instructions. Refer to them frequently and
use them to instruct others who may use this tool. If
you loan this tool to someone else, also loan these
instructions to them to prevent misuse of the product
and possible injury.

the blades have totally stopped
and the battery pack is removed before clearing jammed material from blades. Do not grasp
the exposed cutting blades or cutting edges when picking up or holding the unit.
WARNING: Clear the area to be cut before each use. Remove all objects, such as cords,
lights, wire, or string which can become entangled in the cutting blade and create a risk of
serious personal injury.
WARNING: Avoid trimming too much at one time or through the heavy shrubbery. This can
cause the blades to bind and slow, reducing the cutting efciency.
Top Cutting
Use a wide sweeping motion. A slight downward tilt of the cutting blades in the direction
of motion gives the best cutting results. For better cutting effect, you might as well use the
string to guide the hedge level.
Side Cutting
When trimming the sides of the hedge, begin at the bottom and cut upwards.
