General power tool safety
warnings
Warning: Read all safety warnings and all 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 mainsoperated (corded) power tool or battery-operated (cordless) power
tool.
WORK AREA SAFETY
1
a) Keep work area clean and well lit. Cluttered or dark areas invite
accidents.
b) 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.
c) Keep children and bystanders away while operating a power
tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
2
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 tool. Keep cord away from
heat, oil, sharp edges or moving parts. Damaged or entangled
cords increase the risk of electric shock.
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.
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 mask, 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 adjusting key or wrench before turning the
3
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 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) 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.
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 operations different from those intended could
result in a hazardous situation.
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 must be repaired.
c) 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.
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.
5
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.
b) If the replacement of the supply cord is necessary, this has
to be done by the manufacturer or his agent in order to
avoid a safety hazard.
Additional safety points for your
impact drill
Wear ear protectors when impact drilling. Exposure to noise can
1
cause hearing loss.
Use auxiliary handles supplied with the tool. Loss of control can
2
4
cause personal injury.
3
Hold power tools by insulated gripping surfaces, when
performing an operation where the cutting accessory may
contact hidden wiring or its own cord. Cutting accessory contacting
a “live” wire may make exposed metal parts of the power tool “live”
and could give the operator an electric shock.
4
Do not use the drill near water.
5
Do not use the drill as a screwdriver.
6
Remove the plug from the socket before carrying out any adjustment,
servicing or maintenance.
7
Fully unwind extension cords to avoid potential overheating.
8
When an extension cord is required you must ensure it has the correct
ampere rating for your power tool and that it is in a safe electrical
condition.
9
Ensure your supply voltage is the same as your tool rating plate
voltage.
10
Your tool is double insulated for additional protection against a possible
electrical insulation failure within the tool.
11
Always check walls and ceilings to avoid hidden power cables and
pipes.
12
After long working periods, external metal parts and accessories could
be hot.
13
Wear eye protection when operating this tool.
14
Maintain a firm grip on the handle when you are working. Always use
the auxiliary handles supplied with the tool. Loss of control can cause
personal injury.
