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 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 tools.
Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords
increases the risk of electric shock.
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 safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-
skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce the
risk of personal injuries.
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 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, clothing and gloves
away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
g) 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.
h)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.
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)
protected supply. Use of an RCD reduces the risk of electric shock.

l) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
n) 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.
Have your power tool serviced by a qualified repair person using only identical replacement parts.
This will ensure that the safety of the power tool is maintained.
SERVICE
USE AND HANDLING OF THE CORDLESS
ELECTRICAL POWER TOOL
a) Charge a rechargeable battery unit using only the charger recommended by the manufacturer.
Chargers are often designed for a particular type of rechargeable battery unit. There is the danger
of fire if other types of rechargeable battery units are used.
b) Only the rechargeable battery units supplied are to be used with an electrical power tool. The
use of other rechargeable battery units may lead to the danger of injury or fire.
c) When they are not being used, store rechargeable
battery units away from paperclips, coins, keys, nails, screws or other small metal objects that
could cause the contacts to be bridged. Short-circuiting the contacts of a rechargeable battery
unit may result in heat damage or fire.
d) Fluids may leak out of rechargeable battery units if they are misused. If this happens, avoid
contact with the fluid. If contact occurs, flush the affected area with water. Seek additional medical
help if any of the fluid gets into your eyes. Escaping battery fluid may cause skin irritation or burns.
a) Ensure that the device is switched off before inserting the battery. Inserting a battery into a
power tool that is switched on may result in accidents.
b) Recharge the batteries indoors only because the battery charger is designed for indoor use
only.
c) To reduce the electric shock hazard, unplug the battery charger from the mains before cleaning
the charger.
d) Do not subject the battery to strong sunlight over long periods and do not leave it on a heater.
Heat damages the battery and there is a risk of explosion.
e) Allow a hot battery to cool before charging.
f) Do not open up the battery and avoid mechanical damage to the battery. Risk of short circuit
and fumes may be emitted that irritate the respiratory tract. Ensure fresh air and seek medical
assistance in the event of discomfort.
g) Do not use non-rechargeable batteries!
SPECIAL SAFETY DIRECTIONS FOR BATTERY-OPERATED TOOLS
a) This device can be used by children aged 8 and over and by people with reduced physical,
sensory or mental capacities or with a lack of experience or knowledge, if they are supervised or
have been instructed regarding safe use of the device and understand the resulting risks. Children
are not permitted to play with the device. Cleaning and user maintenance are not to be undertaken
by children without supervision.
b) Children should be supervised to ensure that they do not play with the appliance.
c) To charge the battery, use only the charger supplied. Risk of fire and explosion. This ensures
that the safety of the device is maintained.
d) Before each use, check the charger, cable and plug and have them repaired by qualified
professionals and only with original parts. Do not use a defective charger and do not open it up
yourself. This ensures that the safety of the device is maintained.
CORRECT HANDLING OF THE BATTERY CHARGER
56

e) Connect the charger only to a socket with an earth. Ensure that the mains voltage matches the
specifications on the charger rating plate. Risk of electric shock.
f) Disconnect the charger from the mains before closing or opening connection to the battery /
power tool / device.
g) Keep the charger clean and away from wet and rain. Do not use the charger outdoors. Dirt and
the entry of water increase the risk of electric shock.
h) Operate the charger only with the appropriate original batteries. Charging other batteries may
result in injuries and risk of fire.
I) Avoid mechanical damage to the charger. This can result in internal short circuits.
j) Do not operate the charger on a combustible surface (e.g. paper, textiles). Risk of fire due to
heating during charging.
k) If the power cable for this equipment is damaged, it must be replaced by the manufacturer, a
customer service agent of the same or a similarly qualified person in order to prevent hazards.
l) The battery of the appliance is not fully charged at the time of delivery. It therefore needs to be
fully recharged before you use it for the first time. For the first recharge cycle we recommend that
you charge the battery for about 1 hour. Slot the battery into the base and plug the battery charger
into a mains outlet.
m) When the battery is fully charged, unplug the charger from the mains and from the appliance.
Charging time is approx. 1
hour.
n) Do not charge the battery continuously since this may damage the battery cells.
Note: Repeatedly charging small capacities may damage the battery cells. Recharge the battery
only if the appliance is becoming slow.
o) Do not use the charger to charge non-rechargeable batteries.
Even if properly operating and handling this electric tool, some residual risks will remain. Due to its
construction and build, this electric tool may present the following hazards:
RESIDUAL RISKS
