Rubber Sanding Plate

 For operations with the rubber sanding plate 18, al-

ways mount the hand guard 17.

See graphics page for the mounting sequence.

Screw on round nut 20 and tighten it with the combination

spanner 5/6.

Cup Brush/Disc Brush

 For operations with the cup brush/wheel brush, always

mount the hand guard 17.

See graphics page for the mounting sequence.

The cup brush/disc brush must be able to be screwed onto

the grinder spindle until it rests firmly against the grinder

spindle flange at the end of the grinder spindle threads. Tight-

en the cup brush/disc brush with an open-end spanner.

Quick-clamping Nut

For convenient changing of grinding tools without the use of

additional tools, you can use the quick-clamping nut 13 in-

stead of the clamping nut 12.

 The quick-clamping nut 13 may be used only for grind-

ing or cutting discs.

Use only a flawless, undamaged quick-clamping nut 13.

When screwing on, pay attention that the side of the

quick-clamping nut 13 with printing does not face the

grinding disc; the arrow must point to the index mark 25.

Lock the grinder spindle with

the spindle lock button 1. To

tighten the quick-clamping

nut, firmly turn the grinding

disc in clockwise direction.

A properly fastened, undam-

aged quick-clamping nut can

be manually loosened by

turning the knurled ring in an-

ticlockwise direction.

Never loosen a tight quick-

clamping nut using pliers;

always use the combination

spanner. Apply the combina-

tion spanner 5/6 as shown in

the figure.

Approved Grinding Tools

All grinding tools mentioned in these operating instructions

can be used.

The permissible speed [min

-1

] or the circumferential speed

[m/s] of the grinding tools used must at least match the values

given in the table.

Therefore, observe the permissible rotational/circumferen-

tial speed on the label of the grinding tool.

Rotating the Machine Head

 Before any work on the machine itself, pull the mains

plug.

The machine head can be

rotated with respect to

the machine housing in

90° steps. In this man-

ner, the On/Off switch

can be brought into a

more convenient posi-

tion for special working

situations, e.g. for left-

handed persons.

Completely unscrew the

four screws. Rotate the

machine head carefully,

without removing it from the housing, to the new position.

Screw in and tighten the four screws again.

Dust/Chip Extraction

 Dust from materials such as lead-containing coatings,

some wood types, minerals and metal can be harmful to

one’s health. Touching or breathing-in the dust can cause

allergic reactions and/or lead to respiratory infections of

the user or bystanders.

Certain dust, such as oak or beech dust, is considered car-

cinogenic, especially in connection with wood-treatment

additives (chromate, wood preservative). Materials con-

taining asbestos may only be worked by specialists.

– As far as possible, use a dust extraction system suitable

for the material.

– Provide for good ventilation of the working place.

– It is recommended to wear a P2 filter-class respirator.

Observe the relevant regulations in your country for the

materials to be worked.

 Prevent dust accumulation at the workplace. Dust can

easily ignite.

1 609 92A 2V9 | (23.11.16) Bosch Power Tools

Operation

Starting Operation

 Observe correct mains voltage! The voltage of the pow-

er 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.

When operating the machine with power from mobile genera-

tors that do not have sufficient reserve capacity or are not

equipped with suitable voltage control with starting current

amplification, loss of performance or untypical behavior can

occur upon switching on.

Please observe the suitability of the power generator being used,

particularly with regard to the mains voltage and frequency.

Switching On and Off

To start the power tool, push the On/Off switch 2 forwards.

To lock the On/Off switch 2, press the On/Off switch 2 down

at the front until it latches.

To switch off the power tool, release the On/Off switch 2 or,

if it is locked, briefly push down the back of the On/Off switch

2 and then release it.

To save energy, only switch the power tool on when using it.

 Check grinding tools before using. The grinding tool

must be mounted properly and be able to move freely.

Carry out a test run for at least one minute with no load.

Do not use damaged, out-of-centre or vibrating grind-

ing tools. Damaged grinding tools can burst and cause in-

juries.

Speed preselection (GWS 6-100 E/GWS 6-115 E/GWS 6-125 E)

The required speed can be preselected with the thumbwheel 3 (also while running).

The data in the following table are recommended values.

Working Advice

 Exercise caution when cutting slots in structural walls;

see Section “Information on Structures”.

 Clamp the workpiece if it does not remain stationary

due to its own weight.

 Do not strain the machine so heavily that it comes to a

standstill.

 After heavily straining the power tool, continue to run

it at no-load for several minutes to cool down the acces-

sory.

 Do not touch grinding and cutting discs before they

have cooled down. The discs can become very hot while

working.

 Do not use the power tool with a cut-off stand.

Rough Grinding

 Never use a cutting disc for roughing.

The best roughing results are achieved when setting the ma-

chine at an angle of 30° to 40°. Move the machine back and

forth with moderate pressure. In this manner, the workpiece

will not become too hot, does not discolour and no grooves

are formed.

Flap Disc

With the flap disc (accessory), curved surfaces and profiles

can be worked.

Flap discs have a considerably higher service life, lower noise

levels and lower sanding temperatures than conventional

sanding sheets.

Cutting Metal

 For cutting with bonded abrasives, always use the pro-

tection guard for cutting 15.

When cutting, work with moderate feed, adapted to the mate-

rial being cut. Do not exert pressure onto the cutting disc, tilt

or oscillate the machine.

Do not reduce the speed of running down cutting discs by ap-

plying sideward pressure.

The machine must al-

ways work in an up-

grinding motion. Other-

wise, the danger exists

of it being pushed un-

controlled out of the

cut.

When cutting profiles and square bar, it is best to start at the

smallest cross section.

Cutting Stone

 Provide for sufficient dust extraction when cutting

stone.

 Wear a dust respirator.

 The machine may be used only for dry cutting/grinding.

For cutting stone, it is best to use a diamond cutting disc.

When using the cutting guide with dust extraction protection

guard 22, the vacuum cleaner must be approved for vacuum-

ing masonry dust. Suitable vacuum cleaners are available

from Bosch.

Switch on the machine

and place the front part

of the cutting guide on

the workpiece. Slide the

machine with moderate

feed, adapted to the ma-

terial to be worked.

For cutting especially hard material, e. g., concrete with high

pebble content, the diamond cutting disc can overheat and

become damaged as a result. This is clearly indicated by cir-

cular sparking, rotating with the diamond cutting disc.

In this case, interrupt the cutting process and allow the dia-

mond cutting disc to cool by running the machine for a short

time at maximum speed with no load.

Noticeably decreasing work progress and circular sparking

are indications of a diamond cutting disc that has become

dull. Briefly cutting into abrasive material (e.g. lime-sand

brick) can resharpen the disc again.

Information on Structures

Slots in structural walls are subject to the Standard DIN 1053

Part 1, or country-specific regulations.

These regulations are to be observed under all circumstanc-

es. Before beginning work, consult the responsible structural

engineer, architect or the construction supervisor.

Maintenance and Service

Maintenance and Cleaning

 Before any work on the machine itself, pull the mains

plug.

 For safe and proper working, always keep the machine

and ventilation slots clean.

 In extreme conditions, always use dust extraction as

far as possible. Blow out ventilation slots frequently

and install a portable residual current device (PRCD).

When working metals, conductive dust can settle in the in-

terior of the power tool. The total insulation of the power

tool can be impaired.

Please store and handle the accessory(-ies) carefully.

If the replacement of the supply cord is necessary, this has to

be done by Bosch or an authorized Bosch service agent in or-

der to avoid a safety hazard.
