2. GENERAL SAFETY WARNINGS FOR THE POWER TOOL
WARNING.
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may result in electric shock, fire and/or a serious
injury.
Keep 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.
1. Work area safety
a) Keep work area clean and well lit. Cluttered and dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, for example in the presence of flammable
liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you to
lose control.
2. Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adap-
ters plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce
the risk of electric shock.
b) Avoid any body contact with earthed or grounded surfaces such as pipes, radiators, cookers 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 electrical shock.
d) 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 and moving parts. Damaged or entangled cords increa-
se the risk of electric shock.
e) When operating a power tool outdoors, use an extension cable suitable for outside use. Use of a
cord suitable for outside 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.
3. 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 personal protective equipment. Always wear eye protection. Protective equipment such as
dust masks, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions
will reduce 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 energising power tools that have the switch on invites accidents.
d) Remove any adjustment 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.
e) Do not overreach. Keep proper position and balance at all times. This enables better control of
the 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) 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.
4. Power tool use and care
a) 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.
b) 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 should be repaired.
c) Disconnect the plug from the power source and/or the battery pack from the power tool before
making any adjustment, changing accessories or storing power tools. Such preventive safety mea-
sures reduce the risk of starting the power tool accidentally.
d) 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.
e) 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.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
g) 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 opera-
tions different from those intended could result in a hazardous situation.
5. Battery tool use and care
a) 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.
b) Use power tools only with specifically designated battery packs. Use of any other battery packs
may create a risk of injury and fire.
c) 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 fire.
d) Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact acci-
dentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid
ejected from the battery may cause irritation or burns.
6. Service
a) 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.
3. SPECIAL SAFETY INSTRUCTIONS
Wear ear protection. Exposure to noise can cause hearing loss.
Hold power tool by insulated gripping surfaces, when performing an operation where the drilling
accessory may contact hidden wiring or its own cord. Drilling accessory contacting a “live” wire
may make exposed metal parts of the power tool “live” and could give the operator an electric
shock.
Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure
than by hand.
WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities
contains chemicals known to cause cancer, birth defects or other reproductive harm. Some exam-
ples of these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement and other masonry products, and
• Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well ventilated area, and work with approved safety
equipment, such as those dust masks that are specially designed to filter out microscopic particles.
4. SAFETY ADVICE FOR RECHARGEABLE BATTERY AND CHARGER
WARNING!
During the use of tools supplied with batteries, the basic safety measures must

Vibration total values ah (triax vector sum) determined according to EN 60745-2-6.
Sound level LwA = 95.0 dB (A)
Sound level LpA = 84.0dB (A)
Vibration: ah,HD = 4,366 m²/s
The vibration level given in this information sheet has been measured in accordance with a standar-
dised test given in EN 60745 and may be used to compare one tool with another. It may be used for
a preliminary assessment of exposure.
The declared vibration emission level represents the main applications of the tool. However if the
tool is used for different applications, with different accessories or insertion tools or is poorly main-
tained, the vibration emission may differ. This may significantly increase the exposure level over the
total working period.
An estimation of the level of exposure to vibration should also take into account the times when the
tool is switched off or when it is running but not actually doing the job. This may significantly reduce
the exposure level over the total working period. Identify additional safety measures to protect the
operator from the effects of vibration such as: maintain the tool and the accessories,
keep the hands warm, organisation of work patterns.
