For The Battery Charger
1. Do not place any objects on the
battery charger and do not place the
battery charger on soft surfaces.
2. Please read safety instructions for Li-
ion batteries. There is a risk of
explosion.
3. Liquid ejected from the battery may
cause irritation or burns.
4. If other batteries are used, e.g.
imitations, reconditioned batteries or
third-party products, there is a risk of
injuries as well as damage caused by
exploding batteries.
5. A charger that is suitable for one type
of battery pack may create a risk of fire
when used with another battery pack.
This may cause an internal short-circuit
and the battery to burn, smoke, explode
or overheat.
General Power Tool
Safety Warnings
The term "power tool" in the warnings
refers to your main-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 flammable 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.
Unmodified plugs and matching outlets
will reduce the 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 the 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

5
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.
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
influence 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 the risk of injury.
3. Prevent unintentional starting. Ensure
the switch is in the off-position before
connecting to the power source and/or
battery pack, picking up, or carrying the
tool. Carrying power tools with your
finger on the switch or power tools that
have been turned 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
increase the risk of 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 jewelry. Keep your hair,
clothing and gloves away from moving
parts. Loose clothes, jewelry or long hair
can be caught by moving parts.
7. If devices are provided for the
connection of dust extraction and
collection facilities, ensure that 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 is
designed.
2. Do not use the power tool if it can’t be
turned on and off by its switch. 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

6
before storing the power tool. Such
preventive safety measure reduces the
risk of starting the power tool
accidentally.
4. Store idle power tools out of reach of
children and do not allow persons
unfamiliar with the power tool or these
instructions to operate it. Power tools
are dangerous in the hands of untrained
users.
5. Maintain the 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.
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
specified by the manufacturer. A charger
that is suitable for one type of battery
pack may create a risk of fire when used
with another battery pack.
2. Use power tools only with specifically
designated battery packs. Use of any
other battery packs may create a risk of
injury and fire.
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 fire.
4. Under abusive conditions, liquid may
be ejected from the battery; avoid
contact. If you accidentally contact the
battery liquid, flush it with water. If the
battery liquid contacts the eyes, seek
medical help as soon as possible. Liquid
ejected from the battery may cause
irritation or burns.
Service
Have your power tool serviced by a
qualified repair professional using only
the identical replacement parts. This
will ensure that the safety of the power
tool is maintained.

TIPS ON LAWN CARE
Here are some tips to help you keep your
lawn looking healthy and ensure uniform
growth:
Lawns consist of various grass types.
Frequent mowing promotes the growth of
grass, resulting in strong roots and a firm
sward. If you seldom cut the grass, you
will enhance the development of high-
growing types of grass and other weeds,
such as clover, daisies). The normal
height of a lawn is approx. 4–5 cm. Only
one third of the total height should be
mown; therefore cut 7–8 cm long grass to
normal height.
