Safety Notes
General Power Tool Safety Warnings
WARNING
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.
1) Work area safety
a) Keep work area clean and well lit. Clut-
tered 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. Distrac-
tions 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 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 and moving parts.
Damaged or entangled cords increase the
risk of electric shock.
Read all safety warnings and all
instructions. Failure to follow
e) When operating a power tool outdoors,
use an extension cord suitable for outdoor use. Use of a cord suitable for out-
door use reduces the risk of electric
shock.
f) If operating a power tool in a damp loca-
tion 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. Al-
ways 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 fin-
ger on the switch or energising power
tools that have the switch on invites accidents.
d) Remove any adjusting key or wrench be-
fore 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 footing
and balance at all times. This enables
better control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose cloth-
ing 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 connec-
tion 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 cor-
rect 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.
e) Maintain power tools. Check for mis-
alignment 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. Prop-
erly 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.
5) Service
a) Have your power tool serviced by a qual-
ified repair person using only identical
replacement parts. This will ensure that
the safety of the power tool is maintained.
Safety Warnings for Straight Grinders
Safety Warnings Common for Grinding, Wire
Brushing, Polishing or Carving:
f This power tool is intended to function as a
grinder, carving tool, polisher (GGS 8 CE)
or wire brush (GGS 8 CE). Read all safety
warnings, instructions, illustrations and
specifications provided with this power
tool. Failure to follow all instructions listed
below may result in electric shock, fire
and/or serious injury.
f Do not use accessories which are not spe-
cifically designed and recommended by the
tool manufacturer. Just because the acces-
sory can be attached to your power tool, it
does not assure safe operation.
f The rated speed of the accessory must be at
least equal to the maximum speed marked
on the power tool. Accessories running fast-
er than their rated speed can break and fly
apart.
f The outside diameter and the thickness of
your accessory must be within the capacity
rating of your power tool. Incorrectly sized
accessories cannot be adequately controlled.
f The arbour size of wheels, sanding drum or
any other accessory must properly fit the
spindle or collet of the power tool. Accesso-
ries that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss
of control.
f Mandrel mounted wheels, sanding drums,
cutters or other accessories must be fully
inserted into the collet or chuck. The “overhang” or the length of the mandrel from the
wheel to the collet must be minimal. If the
mandrel is insufficiently held and/or the
overhang of the wheel is too long, the mounted wheel may become loose and ejected at
high velocity.
