Bosch GWS 20-180 H Instructions D'emploi page 15

Pay attention to the direction of rotation. Al-
ways hold the machine so that sparks and
grinding dust fly away from the body.
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.
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.
Never allow children to use the machine.
Bosch is only able to ensure perfect operation
of the machine, if the original accessories in-
tended for it are used.
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

Before any work on the machine itself, pull
the mains plug.
For work with roughing or cutting discs,
the protective guard 6 must be mounted.
Guard with locking screw
The coded projection 8 on the guard 6 ensures
that only a guard that fits the machine type can be
mounted.
Loosen the clamping screw 7, if necessary.
Place the guard 6 with coded projection 8 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 6
must always point to the operator.
Tighten clamping screw 7.
Guard with quick clamp
(Optional extra)
The wheel guard is preadjusted to the di-
ameter of the spindle collar. If required, the
tightening tension of the clamping bracket
can be changed by tightening or loosening
the adjustment screw 13. Always ensure
that the wheel guard 6 is seated tightly on
the spindle collar.
Open the clamping lever 14.
Place the protective guard 6 on the spindle collar
of the machine head and turn to the required po-
sition (working position).
To fasten the protective guard 6, close the clamp-
ing lever 14.
The closed side of the protective guard 6
must always point to the operator.
