Safety instructions
WARNING. Read and understand all instructions. Failure
to follow all instructions listed below may result in
electric shock, fire and/or serious injury. The term
“power tool” in all of the warnings below refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
Save these instructions
Work area
• Keep work area clean and well lit. Cluttered and 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.
• 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 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
outdoor extension cord suitable for outdoor use. Use
of a cord suitable for outdoor use 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 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.
• Use safety equipment. Always wear eye protection.
Safety equipment such as a dust mask, non-skid
safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
• Avoid accidental starting. Ensure the switch is in the
off-position before plugging in. 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 tool on. A wrench or a key that is 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 jewellery.
Keep your hair, clothing and gloves away from moving
parts. Loose clothes, jewellery 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 safer at the rate for which it
was designed.
4
• 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 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 and tool bits etc.,
in accordance with these instructions and in the
manner intended for the particular type of power
tool, taking into account the working conditions
and the work to be performed. Use of the power tool
for operations different from intended could result in a
hazardous situation.
Service
• Have your power tool serviced by a qualified repair
personnel using only identical replacement parts.
This will ensure that the safety of the power tool
is maintained.
Additional safety instructions for drills
Wear ear protectors with impact drills.
Exposure to noise can cause hearing loss.
Use auxiliary handles supplied with the tool.
Loss of control can cause personal injury.
• If possible, always use clamps or a vice to hold your work.
• Always switch off before you put the drill down.
• Ensure that the lighting is adequate.
• Do not put pressure on the drill, such that it slows the
motor down. Allow the drill bit to cut without pressure.
You will get better results and you will be taking better
care of your tool.
• Keep the area free of tripping hazards.
• Do not let anyone under 18 years operate this tool.
• Only use accessory bits in good condition.
• Before drilling, check that there is sufficient clearance
for the drill bit under the workpiece.
• Do not touch the bit after operation. It will be very hot.
• Keep your hands away from under the workpiece.
• Never use your hands to remove sawdust, chips or
waste close by the bit.
• Rags, cloths, cord, string and the like should never be
left around the work area.
• Support the work properly.
• If you are interrupted when operating the drill,
complete the process and switch off before looking up.
• Periodically check that all nuts, bolts and other fixings
are properly tightened.
• When using the drill, use safety equipment including
safety glasses or shield, ear defenders, and protective
clothing including safety gloves. Wear a dust mask if
the drilling operation creates dust.
