Bosch GWS 11-125 Professional Notice Originale page 25

After fitting the abrasive tool, check that the abrasive
u
tool is fitted correctly and can turn freely before
switching on the power tool. Make sure that the abras-
ive tool does not brush against the protective guard or
other parts.
A plastic part (O-ring) is fitted around the cent-
ring collar in the mounting flange (9). If the O-
ring is missing or damaged, the mounting
flange (9) must be replaced before operation
can resume.
Flap disc
Always fit the hand guard (20) when working with the
u
flap disc.
Rubber sanding pad
Always fit the hand guard (20) when working with the
u
rubber sanding pad (22).
See the graphics page for fitting instructions.
Screw on the round nut (24) and tighten with the two-pin
spanner.
Cup brush/disc brush
Always fit the hand guard (20) when working with the
u
cup brush or disc brush.
See the graphics page for fitting instructions.
The cup brush/disc brush must be screwed onto the grinding
spindle until it rests firmly against the grinding spindle flange
at the end of the grinding spindle thread. Tighten the cup
brush/disc brush with an open-ended spanner.
Quick-clamping nut
To change the abrasive tool easily without having to use any
additional tools, you can use the quick-clamping nut (13) in-
stead of the clamping nut (14).
The quick-clamping nut (13) may be used only for
u
grinding or cutting discs.
Only use quick-clamping nuts (13) that are in good work-
ing order and not damaged.
When screwing on, make sure that the printed side of the
quick-clamping nut (13) is not facing the grinding disc;
the arrow must be pointing towards the index mark (26).

Rotating the machine head (see figure A)
Pull the plug out of the socket before carrying out any
u
work on the power tool.
The machine head can be rotated in 90° increments. In this
way, the on/off switch can be brought into a more favourable
handling position for particular applications, e.g. for left-
handed tool users.
Completely unscrew the four screws. Rotate the machine
head carefully, without removing it from the housing, into
the new position. Screw in and retighten the four screws.

If the quick-clamping nut
has been attached correctly
and is not damaged, you
can loosen it by hand by
turning the knurled ring an-
ticlockwise. If the quick-
clamping nut is stuck, do
not attempt to loosen it
with pliers – always use
the two-pin spanner. Posi-
tion the two‑pin spanner as
shown in the figure.
