INTENDED USE
This cordless grass shear is designed for the cutting and trimming of grass, hedges, bushes
and ornamental shrubs in the domestic environment.
For safety reasons it is essential to read this entire instruction manual before initial operation
and to observe all the instructions inside.
This product is intended for private domestic use only, not for commercial trade use. It must
not be used for any purposes other than those described.
GENERAL SAFETY WARNINGS
WARNING: Read all safety directions and instructions.
Omissions in the compliance with safety directions and
instructions can cause electrical shock, re and/or severe
injuries.
Retain all safety directions and instructions for future use.
The term “Power Tools” used in the safety instructions
refers to mains-operated power tools (with power cord)
and to battery operated power tools (without power cord).
Work area safety
1. Keep work area clean and well lit. Cluttered or dark
areas increase the chances of accidents.
2. Do not operate power tools in explosive atmospheres,
in the presence of ammable Iiquids, 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 momentary loss
of 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. Unmodied
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.

GENERAL SAFETY WARNINGS
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
inuence 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
masks, nonskid safety shoes, hard hats, and hearing
protection can reduce personal injury.
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
energizing 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.
7. If devices are provided for the connection of dust
extraction and collection facilities, ensure these
are connected and properly used. The use of dust
collection can reduce dust-related hazards.
Power tool use and care
1. Do not use excessive force while using the power
tool. Use the correct power tool for your application.
The correct power tool will do the job better and more
safely 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.
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. 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 its operation. If
damaged, have the power tool repaired before use.
Many accidents are caused due to poor maintenance.
6. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
GENERAL SAFETY WARNINGS
8 9
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 specied 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 specically 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 intensive use, liquid may be ejected from the
battery; avoid contact. If contact accidentally occurs,
ush with water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the battery
may cause irritation or burns.
GENERAL SAFETY WARNINGS GENERAL SAFETY WARNINGS
Service
1. Have your power tool serviced by a qualied repair
person using only identical replacement parts.
This will ensure that the safety of the power tool is
maintained.
Grass shear safety warnings:
1. Keep all parts of the body away from the cutter blade.

PRODUCT SAFETY WARNINGS
Special Safety Directions for cordless grass shear
1. Keep all body parts away from the blade. Do not
attempt to remove clippings while the blade is
operating or to hold on to material which is to be
cut. Only remove trapped clippings when the tool
is switched off. One moment of carelessness when
using the grass shear can lead to severe injury.
2. Carry the grass shear at the handle with an idle blade.
Always pull on the protective cover during transport
and storage of the Grass shear. Careful handling of
the tool reduces the risk of injury from the blade.
3. Hold the power tool only on the insulated handle
surfaces, as the cutting blade may come into contact
with concealed power cables. Contact between the
cutting blade and a live cable may render metallic
components live and result in an electric shock.
4. Before the work, search the lawn or hedge for
concealed objects, e.g. cable etc. To avoid damaging
the equipment.
5. Wear suitable clothing and work clothes when
working with the equipment. Do not hold the
equipment by the cutting blade or lift it on the cutting
blade. Contact with the cutting blade can cause
injuries.
Further safety directions
1. Only switch on the tool when hands, feet and all
other body parts are at a secure distance to the tool.
Standing too close can increase risk of injury from
cuts.
2. Take care not to injure your hands and feet with the
cutting elements.
3. Remove the power supply unit before working with
the equipment.
4. Do not use the hedge cutter in combination with the
telescopic shaft.
5. The tool is designed to shape hedges and grass. Do
not use the tool to cut branches, hard wood or other.
This helps to avoid damaging the equipment, and
also reduce injury to yourself from debris.
6. Do not attempt to dislodge a blocked/trapped blade
before switching the tool off. Always make sure the
tool is turned off, there is a high risk of injury when
the tool is switched on.
7. Always switch off the tool and remove the battery (if
applicable)
- If you leave the tool unsupervised
- Before removing jams
- Before control- maintenance- or cleaning tasks
- If you have come into contact with a foreign
object
- Whenever the machine starts to vibrate
uncontrollably.

hot environment over a long period of time. Heat
damages the battery and there is a risk of explosion.
2. Allow a hot battery to cool before charging.
