Safety guidelines for cordless power tools
WARNING!
Read all safety warnings and instructions. Failure to follow the warnings and instructions may
result in electric shock, fire and/or serious injury. Save 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 tool.
Work area safety
•
Keep the work area clean and well lit. Cluttered or dark areas invite accidents.
•
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.
*Maximum battery voltage without workload; with workload nominal voltage is 18V.

SAFETY GUIDELINES
SAFETY GUIDELINES
•
Keep children and bystanders away while operating a power tool. Distractions can cause you to
lose control.
Electrical safety
•
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.
•
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.
•
Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the
risk of electric shock.
•
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.
•
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.
•
If operating a power tool in a damp location is unavoidable, use a ground-fault circuit interrupter
(GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.
Personal safety
•
Stay alert, watch what you are doing and use common sense when operating a power tool. Do not
use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while
operating power tools may result in serious personal injury.
•
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
personal injuries.
•
Prevent unintentional starting. Ensure that the switch is in the off-position before connecting to a
power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger
on the switch or plugging in power tools that have the switch on invites accidents.
•
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.
•
Do not overreach. Keep proper footing and balance at all times. This enables better control of the power
tool in unexpected situations.
•
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 in moving parts.
•
If devices are provided for the connection of dust extraction and collection facilities, ensure that
these are connected and properly used. Use of these devices can reduce dust-related hazards.
Power tool use and care
•
Do not force 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.
•
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.
•
Disconnect the plug from the power source and/or the battery pack from the power tool before
making any adjustments, changing accessories, or storing power tools. Such preventive safety
measures reduce the risk of starting the power tool accidentally.
•
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.
•
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.
•
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
•
Use the power tool, accessories, 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
•
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.
•
Use power tools only with specifically designated battery packs. The use of any other battery pack
may create a risk of injury and fire.
•
When the battery pack is not in use, keep it away from other metal objects, such as 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.
•
Under abusive conditions, liquid may be ejected from the battery. Avoid contact. If contact occurs,
flush with water. If liquid comes into contact with the eyes, seek medical help. Liquid ejected from the
battery may cause irritation or burns.
Service
•
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.

•
Hold power tools by the insulated gripping surfaces when performing an operation where the tool
may contact hidden wiring or its own cord. Contact with a “live” wire may make exposed metal parts
of the power tool “live” and could give the operator an electric shock.
•
Wear ear protectors when impact drilling. Exposure to noise can cause hearing loss.
•
Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
•
When working with the power tool, always hold it firmly with both hands and provide for a secure
stance. The power tool is guided more securely with both hands.
•
Keep the cord and charger from heat to prevent damage to the housing or internal parts.
•
Secure the workpiece. Clamping devices or a vise will hold the workpiece in place better than the hand.
•
Do not allow gasoline, oils, petroleum-based products, etc., to come in contact with plastic parts.
These materials contain chemicals that can damage, weaken, or destroy plastic.
•
Always wait until the machine has come to a complete stop before placing it down. The tool insert
can jam and lead to loss of control over the power tool.
•
Before performing any kind of work on the machine (e.g., maintenance, tool change, etc.) as well
as when transporting and storing it, always set the direction-of-rotation switch to the centre
(locked) position. Unintentional activation of the On/Off switch may result in personal injury.
•
Do not open the battery. There is risk of a short circuit.
•
Protect the battery from heat and fire. There is risk of explosion.
•
Wear ear protectors when using the hammer drill. Exposure to noise can cause hearing loss.
•
Use protective gloves when removing the bit from the tool, or first allow the clamp to cool down.
The bit may be hot after prolonged use.
•
Use protective gloves when operating the tool. Protective gloves can help to keep you from being
burnt and hurt.
•
Keep your hands away from the motor-housing vents. Hot gas comes from the vents during
operation.
•
Release the trigger immediately when a screw is tightened to avoid breaking the screw.
•
For best results, your battery tool should be charged in a location where the temperature is more
than 0°C (32°F) but less that 40°C (104°F). Do not store outside or in vehicles.
