Clean the grinding spindle (26) and all the parts to be fitted.
Lock the grinding spindle with the spindle lock button (3)
before clamping and releasing the abrasive tools.
Do not press the spindle lock button while the grind-
u
ing spindle is moving. The power tool may become dam-
aged if you do this.
Grinding/Cutting Disc
Pay attention to the dimensions of the abrasive tools. The
diameter of the hole must match that of the hub flange. Do
not use an adapter or reducer.
When using diamond cutting discs, ensure that the arrow in-
dicating the direction of rotation on the diamond cutting disc
matches the direction of rotation of the power tool (see the
direction of rotation arrow on the machine head).
See the graphics page for fitting instructions.
Use the quick-clamping nut (22) to secure the grinding/cut-
ting disc without the need for additional tools.
Note: When assembling bonded grinding or cutting discs us-
ing the supplied mounting flange (15) and the quick-clamp-
ing nut (22), the use of intermediate layers is not necessary.
To secure the grinding/cutting disc, place the mounting
flange with O-ring (15) on the grinding spindle (26) and
screw on the quick-clamping nut (22).
Only use the quick-clamping nut (22) for grinding/cutting
discs up to a maximum diameter of 150 mm.
The quick-clamping nut (22) may be used only for
u
grinding or cutting discs.
Only use quick-clamping nuts (22) that are in good
u
working order and not damaged.
When screwing on, make sure that the printed side of
u
the quick-clamping nut (22) is not facing the grinding
disc.
Always secure a grinding/cutting disc using only the
u
quick-clamping nut (22) supplied.
Press the spindle lock button (3) to
lock the grinding spindle. To tighten
the quick-clamping nut (22), fold up
the bar and turn the quick-clamping
nut firmly clockwise. Then fold down
the bar to secure the quick-clamping
nut. It is not sufficient to tighten the
disc along the edge.
Quick-clamping nuts (22) that are
properly secured and not damaged
can be removed by hand. To do this,
fold up the bar and turn the quick-
clamping nut firmly anticlockwise. If
the quick-clamping nut is stuck, do not
attempt to loosen it with a tool – al-
ways use a two-pin spanner.
Bosch Power Tools
After fitting the mounting flange and
the grinding/cutting disc, the free
thread length of the grinding spindle
must be at least 4 mm.
Ensure that the abrasive tool is firmly seated, so that it does
not twist away from the spindle in the runout of the power
tool.
A plastic part (O-ring) is fitted around
the centring collar in the mounting
flange (15). If the O-ring is missing
or damaged, the mounting
flange (15) must be replaced before
operation can resume.
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.
Approved abrasive tools
You can use all the abrasive tools mentioned in these operat-
ing instructions.
-1
The permissible speed [min ] or the circumferential speed
[m/s] of the abrasive tools used must at least match the val-
ues given in the table.
It is therefore important to observe the permissible rota-
tional/circumferential speed on the label of the abrasive
tool.
