Safety Notes
General Power Tool Safety Warnings
Read all safety warnings and all
instructions. Failure to follow
the warnings and instructions may result in elec-
tric 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, radia-
tors, 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.
e) When operating a power tool outdoors,
use an extension cord suitable for out-
door 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 cur-
rent 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 influ-
ence of drugs, alcohol or medication. A
moment of inattention while operating
power tools may result in serious person-
al 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 protec-
tion 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 bat-
tery 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 acci-
dents.
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 inju-
ry.
e) Do not overreach. Keep proper footing
and balance at all times. This enables
better control of the power tool in unex-
pected 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 fa-
cilities, 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 de-
signed.
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 re-
paired.
c) Disconnect the plug from the power
source and/or the battery pack from the
power tool before making any adjust-
ments, 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 unfa-
miliar with the power tool or these in-
structions 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 condi-
tion that may affect the power tool’s op-
eration. 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 in-
structions, taking into account the work-
ing conditions and the work to be per-
formed. 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 hard-
ware of the power tool will run out of bal-
ance, 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 “over-
hang” 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 mount-
ed wheel may become loose and ejected at
high velocity.

Bosch Power Tools 3 609 929 C06 | (16.12.10)
f Do not use a damaged accessory. Before
each use inspect the accessory such as
abrasive wheels for chips and cracks, sand-
ing drum for cracks, tear or excess wear,
wire brush for loose or cracked wires. If
power tool or accessory is dropped, inspect
for damage or install an undamaged acces-
sory. After inspecting and installing an ac-
cessory, position yourself and bystanders
away from the plane of the rotating acces-
sory and run the power tool at maximum no-
load speed for one minute. Damaged acces-
sories will normally break apart during this
test time.
f Wear personal protective equipment. De-
pending on application, use face shield,
safety goggles or safety glasses. As appro-
priate, wear dust mask, hearing protectors,
gloves and workshop apron capable of stop-
ping small abrasive or workpiece frag-
ments. The eye protection must be capable
of stopping flying debris generated by vari-
ous operations. The dust mask or respirator
must be capable of filtrating particles gener-
ated by your operation. Prolonged exposure
to high intensity noise may cause hearing
loss.
f Keep bystanders a safe distance away from
work area. Anyone entering the work area
must wear personal protective equipment.
Fragments of workpiece or of a broken ac-
cessory may fly away and cause injury be-
yond immediate area of operation.
f Hold power tool by insulated gripping sur-
faces only, when performing an operation
where the cutting accessory may contact
hidden wiring or its own cord. Cutting ac-
cessory contacting a “live” wire may make ex-
posed metal parts of the power tool “live”
and could give the operator an electric
shock.
f Always hold the tool firmly during the start-
up. The reaction torque of the motor, as it ac-
celerates to full speed, can cause the tool to
twist.
f Use clamps to support workpiece whenever
practical. Never hold a small workpiece in
one hand and the tool in the other hand
while in use. Clamping a small workpiece al-
lows you to use both hands to control the
tool. Round material such as dowel rods,
pipes or tubing have a tendency to roll while
being cut, and may cause the bit to bind or
jump toward you.
f Position the cord clear of the spinning ac-
cessory. If you lose control of the power tool,
the cord may be cut or snagged and your
hand or arm may be pulled into the spinning
accessory.
f Never lay the power tool down until the ac-
cessory has come to a complete stop. The
spinning accessory may grab the surface and
pull the power tool out of your control.
f After changing the bits or making any adjust-
ments, make sure the collet nut, chuck or
any other adjustment devices are securely
tightened. Loose adjustment devices can un-
expectedly shift, causing loss of control, loose
rotating components will be violently thrown.
f Do not run the power tool while carrying it
at your side. Accidental contact with the
spinning accessory could snag your clothing,
pulling the accessory into your body.
f Regularly clean the power tool’s air vents.
The motor’s fan will draw the dust inside the
housing and excessive accumulation of pow-
dered metal may cause electrical hazards.
f Do not operate the power tool near flamma-
ble materials. Sparks could ignite these ma-
terials.
f Do not use accessories that require liquid
coolants. Using water or other liquid cool-
ants may result in electrocution or shock.
Kickback and related warnings
f Kickback is a sudden reaction to a pinched or
snagged rotating wheel, backing pad, brush
or any other accessory. Pinching or snagging
causes rapid stalling of the rotating accesso-
ry which in turn causes the uncontrolled
power tool to be forced in the direction op-
posite of the accessory’s rotation at the
point of the binding.
OBJ_BUCH-1269-003.book Page 17 Thursday, December 16, 2010 4:05 PM
18 | English
3 609 929 C06 | (16.12.10) Bosch Power Tools
For example, if an abrasive wheel is snagged
or pinched by the workpiece, the edge of the
wheel that is entering into the pinch point
can dig into the surface of the material caus-
ing the wheel to climb out or kick out. The
wheel may either jump toward or away from
the operator, depending on direction of the
wheel’s movement at the point of pinching.
Abrasive wheels may also break under these
conditions.
Kickback is the result of power tool misuse
and/or incorrect operating procedures or
conditions and can be avoided by taking
proper precautions as given below.
f Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. The operator can
control kickback forces, if proper precau-
tions are taken.
f Use special care when working corners,
sharp edges, etc. Avoid bouncing and snag-
ging the accessory. Corners, sharp edges or
bouncing have a tendency to snag the rotat-
ing accessory and cause loss of control or
kickback.
f Do not attach a thin toothed saw blade.
Such blades create frequent kickback and
loss of control.
f Always feed the bit into the material in the
same direction as the cutting edge is exiting
from the material (which is the same direc-
tion as the chips are thrown). Feeding the
tool in the wrong direction causes the cutting
edge of the bit to climb out of the work and
pull the tool in the direction of this feed.
f When using cut-off wheels, high-speed cut-
ters or tungsten carbide cutters, always
have the work securely clamped. These
wheels will grab if they become slightly cant-
ed in the groove, and can kickback. When a
cut-off wheel grabs, the wheel itself usually
breaks. When the steel saw, high-speed cut-
ters or tungsten carbide cutter grab, it may
jump from the groove and you could lose
control of the tool.
Additional safety instructions for grinding
f Use only wheel types that are recommend-
ed for your power tool and only for recom-
mended applications. For example: do not
grind with the side of a cut-off wheel. Abra-
sive cut-off wheels are intended for peripher-
al grinding, side forces applied to these
wheels may cause them to shatter.
f For threaded abrasive cones and plugs use
only undamaged wheel mandrels with an
unrelieved shoulder flange that are of cor-
rect size and length. Proper mandrels will re-
duce the possibility of breakage.
f Do not “jam” the cut-off wheel or apply ex-
cessive pressure. Do not attempt to make
an excessive depth of cut. Overstressing the
wheel increases the loading and susceptibili-
ty to twisting or binding of the wheel in the
cut and the possibility of kickback or wheel
breakage.
f Do not position your hand in line with and
behind the rotating wheel. When the wheel,
at the point of operation, is moving away
from your hand, the possible kickback may
propel the spinning wheel and the power
tool directly at you.
f When wheel is binding or when interrupting
a cut for any reason, switch off the power
tool and hold the power tool motionless un-
til the wheel comes to a complete stop. Nev-
er attempt to remove the cut-off wheel from
the cut while the wheel is in motion other-
wise kickback may occur. Investigate and
take corrective action to eliminate the cause
of wheel binding.
f Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed
and carefully reenter the cut. The wheel may
bind, walk up or kickback if the power tool is
restarted in the workpiece.
f Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback.
Large workpieces tend to sag un-
der their own weight. Supports must be
placed under the workpiece near the line of
cut and near the edge of the workpiece on
both sides of the wheel.

Bosch Power Tools 3 609 929 C06 | (16.12.10)
f Use extra caution when making a “pocket
cut” into existing walls or other blind areas.
The protruding wheel may cut gas or water
pipes, electrical wiring or objects that can
cause kickback.
Safety warnings specific for polishing
operations (GGS 8 CE)
f Do not allow any loose portion of the polish-
ing bonnet or its attachment strings to spin
freely. Tuck away or trim any loose attach-
ment strings. Loose and spinning attach-
ment strings can entangle your fingers or
snag on the workpiece.
Safety warnings specific for wire brushing
operations (GGS 8 CE)
f Be aware that wire bristles are thrown by
the brush even during ordinary operation.
Do not overstress the wires by applying ex-
cessive load to the brush. The wire bristles
can easily penetrate light clothing and/or
skin.
f Allow brushes to run at operating speed for
at least one minute before using them. Dur-
ing this time no one is to stand in front or in
line with the brush. Loose bristles or wires
will be discharged during the run-in time.
f Direct the discharge of the spinning wire
brush away from you. Small particles and ti-
ny wire fragments may be discharged at high
velocity during the use of these brushes and
may become imbedded in your skin.
Additional safety warnings
Wear safety goggles.
f Use suitable detectors to determine if utili-
ty lines are hidden in the work area or call
the local utility company for assistance.
Contact with electric lines can lead to fire
and electric shock. Damaging a gas line can
lead to explosion. Penetrating a water line
causes property damage or may cause an
electric shock.
f Release the On/Off switch and set it to the
off position when the power supply is inter-
rupted, e. g., in case of a power failure or
when the mains plug is pulled. This prevents
uncontrolled restarting.
f Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held
more secure than by hand.
Products sold in GB only: Your product is fitted
with an BS 1363/A approved electric plug with

Noise/Vibration Information
Measured sound values determined according to EN 60745.
The vibration emission level given in this infor-
mation sheet has been measured in accordance
with a standardised 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 repre-
sents the main applications of the tool. However
if the tool is used for different applications, with
different accessories or poorly maintained, the
vibration emission may differ. This may signifi-
cantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibra-
tion should also take into account the times
when the tool is switched off or when it is run-
ning but not actually doing the job. This may sig-
nificantly reduce the exposure level over the to-
tal 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.

Assembly
f Before any work on the machine itself, pull
the mains plug.
Mounting the Grinding Tools
(see figure A)
f Only use properly fitting and undamaged
open-end spanners (see “Technical Data”).
Clean the grinder spindle 3 and all parts to
be mounted.
Hold the grinder spindle 3 with open-end
spanner 8 by the spanner flats.
Loosen the clamping nut 2 with open-end
spanner 9 by applying it to the spanner flats
and turning in anticlockwise direction.
Insert the clamping shaft of the grinding tool
to the stop into the collet chuck 1.
Hold the grinder spindle 3 firmly with open-
end spanner 8 and clamp the tool bit with
open-end spanner 9 by the spanner flats,
turning in clockwise direction.
The grinding tools must run completely concen-
trical. Do not continue to use out-of-round grind-
ing accessories, instead, replace before contin-
uing to work.
f Do not tighten the collet chuck of the
clamping nut as long as no grinding acces-
sory is mounted. Otherwise, the collet chuck
can become damaged.
Dust/Chip Extraction
f Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one’s health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
Provide for good ventilation of the work-
ing place.
It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
f Prevent dust accumulation at the work-
place. Dusts can easily ignite.
Operation
Starting Operation
f Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
Switching On and Off
To start the power tool, push the On/Off switch
5 forwards.
To lock the On/Off switch 5, press the On/Off
switch 5 down at the front until it latches.
To switch off the power tool, release the On/Off
switch 5 or, if it is locked, briefly push down the
back of the On/Off switch 5 and then release it.
Kickback stop
In case of a sudden drop in speed, e.g., caused
by a jammed disc while cutting, the power sup-
ply to the motor is electronically interrupted.
To restart the operation, switch the On/Off
switch 5 to the Off position and start the ma-
chine again.
Constant Electronic Control
Constant electronic control holds the speed
constant at no-load and under load, and ensures
uniform working performance.

Speed preselection
(GGS 8 CE/GGS 28 CE/GGS 28 LCE)
The required speed can be preselected with the
thumbwheel 6 (also while running).
The required speed depends on the material be-
ing worked and the diameter of the application
tool. Observe the maximal allowable speed of
the application tool.
Working Advice
Optimum grinding results are achieved when
the grinding tool is moved uniformly back and
forth with light pressure. Pressure that is too
strong reduces the performance capability of
the machine and causes the grinding tool to
wear more quickly.
Maintenance and Service
Maintenance and Cleaning
f Before any work on the machine itself, pull
the mains plug.
f For safe and proper working, always keep
the machine and ventilation slots clean.
f In extreme conditions, always use dust ex-
traction as far as possible. Blow out ventila-
tion slots frequently and install a residual
current device (RCD). When working metals,
conductive dust can settle in the interior of
the power tool. The total insulation of the
power tool can be impaired.
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an after-sales service
centre for Bosch power tools.
In all correspondence and spare parts order,
please always include the 10-digit article
number given on the type plate of the machine.
