Bosch 7-115 Operations Instructions download pdf (Page 14)

Contact with a “live” wire will make exposed metal parts

of the tool “live” and shock the operator.

• Do not drill, cut or saw into blind areas where elec-

tric, gas or water lines may exist. Use suitable detec-

tors to determine if these lines are hidden in the work

area or call the local utility company for assistance.

Contact with electric lines may cause re or electric

shock. Damaging a gas line can result in an explosion.

Penetrating a water pipe will cause property damage or

may cause an electric shock.

• For work with roughing or cutting discs, the protective

guard must be mounted. For work with the rubber sand-

ing plate 13 or disc brush/ap disc, mounting the hand

protector 12 (accessory) is recommended.

• Use a vacuum cleaner for drawing off the dust when

working with stone. The vacuum cleaner must be ap-

proved for masonry dust. When cutting stone, use the

cutting guide.

• Do not work with materials containing asbestos.

• Use only grinding tools with a permissible speed at least

as high as the noload speed of the machine.

• Check grinding tools before use. The grinding tool must

be properly mounted and turn freely. Perform a test run

for at least 30 seconds with-out load. Do not use dam-

aged, out-of-round or vibrating grinding tools.

• Protect the grinding tool from impact, shock and grease.

• Apply the machine to the workpiece only when switched

on.

• Keep hands away from rotating grinding tools.

• Pay attention to the direction of rotation. Al-ways hold the

machine so that sparks and grinding dust y away from

the body.

• When grinding metal, ying sparks are produced. Take

care that no persons are endangered. Due to danger of

re, no combustible materials should be located in the vi-

cinity (spark ight zone).

• Be careful when cutting grooves, e. g. in load-carrying

walls: See information on structures.

• Blocking the cutting disc leads to jerking reac-tion forces

on the machine. In this case switch off the machine im-

mediately.

• Pay attention to the dimensions of the grinding disc. The

mounting hole diameter must t the mounting ange 7

without play. Do not use reducer pieces or adapters.

• Never use cutting discs for rough grinding. Do not exert

any lateral pressure on the cutting discs.

• Observe the manufacturer’s instructions for mounting

and using grinding tools.

• Caution! The grinding tool runs on after the machine is

switched off.

• Do not clamp the machine in a vice.

• Never allow children to use the machine.

• Bosch is only able to ensure perfect operation of the ma-

chine if the original accessories intended for it are used.

Information structures

Slots in load carrying walls are subject to the Standard DIN

1053, Part 1 or country-specic regulations.

These regulations are to be observed under all circumstanc-

es. Before beginning work, consult the responsible structur-

al engineer, architects or the construction supervisor.

Mounting the protective devices

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

plug.

Protective Guard

• For work with roughing or cutting discs, the protec-

tive guard must be mounted.

Open the clamping lever or the screw.

Place the protective guard with cod-

ed cams into the respectively coded

grooves on the spindle collar of the ma-

chine head and turn anti-clockwise to

the required position (working position).

To fasten the protective guard, close the

clamping lever or the screw.

The closed side of the protective guard

must always point to the operator.

Warning! For the model GWS 6-115 the protective guard

is xed with a screw. In this case a screwdriver should be

used to loosen or to tight the screw.

Note: Coded notches on the protective guard ensure that

only a protective guard that ts the machine type can be

mounted. Disassemble in the reverse sequence.

Auxiliary Handle

• For all work with the machine, the auxiliary handle 3

must be mounted.

Screw the auxiliary handle 3 on the right or left of the ma-

chine head depending on the working method.

Auxiliary handle with vibration absorption 16 (accessory)

The vibration-dampening auxiliary

handle reduces the vibrations, mak-

ing operation more comfortable and

secure.

Do not make any alterations to the auxiliary

handle.

Do not continue to use an auxiliary handle if it is damaged.

Hand Protector (Accessory)

For work with the rubber sanding plate 13 or disc brush/ ap

disc, mounting the hand protector 12 (accessory) is recom-

mended. The hand protector 12 is fastened with the auxil-

iary handle 3.

Mounting the grinding tools (accessories)

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

plug.

Use only grinding tools with a permissible speed

at least as high as the no-load speed of the ma-

chine.

Roughing and cutting discs become very hot while

working; do not touch until they have cooled.

• Clean the grinder spindle and all parts to be mounted.

For clamping and loosening the grinding tools, lock the

grinder spindle 4 with the spindle locking button 1.
