Bosch GWS 180 Bedienungsanleitung Seite 16

When grinding metal, flying sparks are pro-
duced. Take care that no persons are endan-
gered. Due to danger of fire, no combustible
materials should be located in the vicinity
(spark flight zone).
Be careful when cutting grooves, e. g. in load-
carrying walls: See information on structures.
Be careful of hidden electrical lines or gas and
water pipes. Check the working area, e. g. with
a metal detector.
Blocking the cutting disc leads to jerking reac-
tion forces on the machine. In this case switch
off the machine immediately.
Pay attention to the dimensions of the grinding
disc. The mounting hole diameter must fit the
mounting flange 9 without play. Do not use re-
ducer 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.
Bosch is only able to ensure perfect function-
ing of the machine if the original accessories
intended for it are used.
Intended Use
The machine is intended for cutting, roughing and
brushing metal and stone materials without using
water. For cutting stone, a cutting guide is re-
quired.
Information Structures
Slots in load carrying walls are subject to the
Standard DIN 1053, Part 1 or country-specific
regulations.
These regulations are to be observed under all
circumstances. Before beginning work, consult
the responsible structural engineer, architects or
the construction supervisor.

Before any work on the machine itself, pull
the mains plug.
For work with roughing or cutting discs,
the protective guard 5 must be mounted.
Guard with locking screw
The coded projection 14 on the guard 5 ensures
that only a guard that fits the machine type can be
mounted.
Loosen the clamping screw 13, if necessary.
Place the guard 5 with coded projection 14 into
the coded groove on the spindle collar of the ma-
chine head and rotate to the required position
(working position).
The closed side of the protective guard 5
must always point to the operator.
Tighten clamping screw 13.
Guard with quick clamp
(Optional extra)
The guard is pre-adjusted to the diameter
of the spindle collar. Therefore do not
loosen or tighten the adjustment screw 7.
Open the clamping lever 8.
Place the protective guard 5 on the spindle collar
of the machine head and turn to the required po-
sition (working position).
To fasten the protective guard 5, close the clamp-
ing lever 8.
The closed side of the protective guard 5
must always point to the operator.
Auxiliary Handle
For all work with the machine, the auxiliary
handle 4 must be mounted.
Screw the auxiliary handle 4 into the head of the
machine according to the working method.
Hand Protector (Optional extra)
For work with the rubber sanding plate 19 or with
the cup brush 22/disc brush/flap disc, mounting
the hand protector 17 (optional extra) is recom-
mended. The hand protector 17 is fastened with
the auxiliary handle 4.
