General safety regulations for electric tools
CAUTION: Read all safety regulations and
instructions.
Any failures made in following the safety regulations
and instructions may result in an electric shock, fire
and/or serious injury.
Keep all safety regulations and instructions in a
safe place for future use.
The term “electric tool” used in the safety regulations
refers to electric tools operated from the mains power
supply (with a power cable) and to battery operated
electric tools (without a power cable).
1. Workplace safety
앬Keep your work area clean and well illuminat-
ed. Untidy or unlit work areas can result in acci-
dents.
앬Do not use this tool in a potentially explosive
environment containing combustible liquids,
gases or dust.
Electric tools generate sparks, which can in turn
ignite dust or vapors.
앬Keep children and other persons away from
the electric tool while it is being used.
Allowing yourself to get distracted can cause you
to lose control of the tool.
2. ELECTRICAL SAFETY
앬The toolʼs connector plug must be able to fit
into the socket outlet. Do not modify the plug
in any way! Do not use adapter plugs in
conjunction with electrically grounded tools.
Unmodified plugs and matching socket outlets
reduce the risk of an electric shock.
앬Avoid touching grounded surfaces, such as
those of pipes/tubes, heaters, cookers and
refrigerators.
There is an increased risk of getting an electric
shock if you are electrically grounded.
앬Keep the tool away from rain and moisture/wet
conditions.
Penetration of water into an electric tool increases
the risk of an electric shock.
앬Do not use the cable to carry the tool, hang it
up or pull the plug out of the socket. Keep the
cable away from sources of heat, oil, sharp
edges and moving tool parts.
Damaged or tangled cable increases the risk of an
electric shock.
앬If you intend to use an electric tool outdoors,
ensure that you only use extension cable that
is approved for outdoor applications.
Using extension cable that is approved for outdoor
applications reduces the risk of an electric shock.
앬If operation of the electric tool in a damp envi-
ronment can not be avoided, use a earth-leak-
age circuit-breaker. The earth-leakage circuit-
breaker reduces the risk of an electric shock.
3. PERSONAL SAFETY
앬Be alert, work conscientiously and exercise
appropriate caution when using the electric
tool. Do not use the tool if you are tired or are
under the influence of drugs/medication or
alcohol.
One moment of carelessness or lack of attention
when using the electric tool can cause serious
bodily injury!
앬Always wear personal protective equipment
(PPE), including safety goggles.
Wearing personal protective equipment such as a
dust mask, non-slip footwear, protective headgear
and ear muffs (depending upon the type of electric
tool and the particular application) reduces the risk
of sustaining injury.
앬Make sure that the tool cannot start up acci-
dentally. Ensure that the electric tool is
switched off before you connect the tool to the
power supply and/or insert the battery, or pick
up or carry the tool.
Physically touching the switch with your finger
when carrying the tool or connecting the tool to
the power supply switched on can lead to
accidents.
앬Remove adjusting tools/wrench(es) prior to
switching on the power tool.
A tool or wrench that is positioned inside a rotating
power tool part can cause injury.
앬Avoid abnormal working postures. Make sure
you stand squarely and keep your balance at
all times.
This way, you will be able to have better control
over the tool in unexpected situations.
앬Wear suitable clothes. Never wear loose fitting
clothes or jewelry. Keep hair, clothes and
gloves away from moving parts.
Loose clothing, dangling jewelry and long hair can
be caught by moving parts.
앬If dust extraction and dust collection devices
can be mounted, ensure that these are
connected and are properly used.
The use of a dust extraction system can reduce
the danger posed by dust.

4. Using the treatment of electric tools
앬Do not overload your tool. Only use suitable
electric tools to perform your work.
Using the right electric tool allows you to work
better and safer within the toolʼs quoted capacity
range.
앬Do not use an electric tool whose switch is
defective.
An electric tool that no longer can be switched on
or off is dangerous and must be repaired.
앬Pull the plug out of the socket and/or remove
the battery before making any adjustments to
the tool, changing accessories or put the tool
down.
This precaution eliminates the possibility of
inadvertently starting the tool.
앬When not in use, store electric tools out of the
reach of children. Do not allow those persons
to use this tool who are unfamiliar with it or
who have not read these instructions.
Electric tools are dangerous when they are used
by inexperienced persons.
앬Take good care of your tool. Check that
moving parts properly function and do not jam,
that parts are not broken off or damaged in any
way and that the tool can be used to its full
capacity. Have damaged parts repaired prior to
using the tool.
The cause of many accidents can be traced back
to poorly maintained electric tools.
앬Keep your blades sharp and clean.
Properly maintained blades with sharp edges jam
less frequently and are easier to use.
앬Make sure to use electric tools, accessories,
attachments, etc. in accordance with these
instructions. Take the conditions in your work
area and the job in hand into account.
Using electric tools for applications other than
those intended can lead to dangerous situations.
5. SERVICE
앬Have your tool repaired only by authorized
specialists using original replacement parts.
This will ensure that your tool remains safe to use.
Safety instructions for hedge trimmers
Read the safety instructions and operating instruc-
tions carefully and follow them.
1. Before carrying out any work on the hedge trim-
mer, pull the mains plug, for example
- Damage to the cable
- Cleaning the blades
- Checking in the event of faults
- Cleaning and maintenance
- Putting down without supervision
2. This machine can cause serious injuries. Read
the operating instructions carefully for details of
the correct handling, preparation, maintenance,
starting and shutting down the machine. Make
yourself familiar with all the adjustable parts and
how to use the machine correctly.
3. The hedge trimmer must be held in both hands.
4. Check the connection cable for signs of damage
and ageing before use.
5. The hedge trimmer may only be used if the con-
nection cable is undamaged.
6. Check the cutter at regular intervals for signs of
damage and have any repair work to the cutting
tool carried out correctly and then ask your elec-
trician.
7. If the cutter blocks, for example due to thick
branches, etc. the hedge trimmer must be
stopped immediately – pull the plug and only
then may the cause of the blockage be removed.
8. Always place the cover over the cutter when
transporting and storing the machine.
9. Only use cables and plug equipment that is
approved for outdoor use.

attempting to remove any jammed cuttings. A
memory of inattentiveness when using the hedge
trimmer may result in serious injuries.
18. Hold the hedge trimmer by the handled when
the blades are at a standstill, always close the
safety cover when transporting or storing the
hedge trimmer. Handling the machine with care
will reduce the risk of injury from the blades.
19. Keep the cable away from the cutting area.
Whilst you are working the cable may be covered
in the branches which means that you might cut
through it by accident,
20. Look in the hedge for concealed objects, such as
wire fences, before starting work.
21. If the connection lead has to be replaced, this
work must be carried out by the manufacturer or
one of its agents to prevent safety risks.

6. Start-up and operation
Important! This hedge trimmer is suitable for cutting
hedges, bushes and shrubs. Any use which is not
expressly permitted in manual may result in damage
to the hedge trimmer and place the user in serious
danger.
The hedge trimmer is equipped with a two-handed
safety switch.
The machine works only when the switch on the
steady grip (Figure 2 / Item 1) is pressed with one
hand and the switch on the handle (Figure 2 / Item 2)
is pressed with the other hand.
If either switch is released, the cutters will stop mov-
ing.
Please watch out for the cutters as they slow
down to a standstill.
- Please check that the cutters work properly. The
twin-bladed cutters rotate in opposite directions,
thus guaranteeing high cutting performance and
smooth operation.
- Before use, fasten the extension cable in the
stress-relief clip (see Fig. 4).
- When working outdoors, use extension cables that
are approved for the purpose.
7. Notes on working practice
앬A hedge trimmer can be used to cut shrubs and
bushes as well as hedges.
앬To obtain the best cutting results, hold the hedge
trimmer so that the cutter teeth are at an angle of
approx. 15° in relation to the hedge (see Figure
5).
앬The twin-bladed cutters rotate in opposite direc-

GB
tions, thus enabling cutting in both directions (see
Figure 6).
앬It is recommended to tie a guide line of string or
the like along the hedge so that you cut the hedge
to a level height. Cut off all branches which protru
de beyond the guide line (see Figure 7).
앬Cut the sides of the hedge with curve-shaped
movements from the bottom up (see Figure 8).
8. Maintenance, care and storage
앬Before you clean the machine or put it away,
switch off and pull out the power plug.
앬The cutters should be cleaned and lubricated at
regular intervals in order to ensure best perfor
mance at all times. Remove deposits with a brush
and apply a thin film of oil (see Figure 9).
Please use biologically degradable oils.
앬Clean the plastic body with a mild household clea-
ning agent and a damp cloth. Do not use aggres-
sive agents or solvents.
앬Prevent water getting inside the device at all cost.

tFor EU countries only
Never place any electric tools in your household refuse.
To comply with European Directive 2002/96/EC concerning old electric and electronic equipment and its
implementation in national laws, old electric tools have to be separated from other waste and disposed of
in an environment-friendly fashion, e.g. by taking to a recycling depot.
Recycling alternative to the demand to return electrical devices:
As an alternative to returning the electrical device, the owner is obliged to cooperate in ensuring that the
device is properly recycled if ownership is relinquished. This can also be done by handing over the used
device to a returns center, which will dispose of it in accordance with national commercial and industrial
waste management legislation. This does not apply to the accessories and auxiliary equipment without
any electrical components which are included with the used device.
