Hand guard
Always fit the hand guard (21) when working with the
u
rubber sanding pad (22) or with the cup brush/conical
brush/diamond annular cutter.
Attach the hand guard (21) to the auxiliary handle (6)/(32).
Standard auxiliary handle/low-vibration auxiliary handle
Screw the auxiliary handle (6)/(32) on the right or left of the
machine head depending on the working method.
Do not operate your power tool without the auxiliary
u
handle (6)/(32).
Do not continue to use the power tool if the auxiliary
u
handle (6)/(32) is damaged. Do not make any altera-
tions to the auxiliary handle (6)/(32).
fortably.
Fitting the Abrasive Tools
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Do not touch grinding and cutting discs until they have
u
cooled down. The discs can become very hot while work-
ing.
Clean the grinding spindle (18) and all the parts to be fitted.
Lock the grinding spindle with the spindle lock button (2)
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 mounting flange.
Do not use an adapter or reducer.
When using diamond cutting discs, make sure that the direc-
tion of rotation arrow on the diamond cutting disc corres-
ponds to the direction of rotation of the machine (see direc-
tion of rotation arrow on the housing).
See the graphics page for fitting instructions.
Note: When assembling bonded grinding or cutting discs us-
ing the supplied mounting flange (10) and the clamping
nut (15) or quick-clamping nut (16), the use of intermediate
layers is not necessary.
To secure the grinding/cutting disc, place the mounting
flange with O-ring (10) on the grinding spindle (18) and
screw on the clamping nut (15). Pay attention to the align-
ment of the clamping nut (15) depending on the grinding/
cutting disc that is being used (see figures at the beginning
of the.operating manual), and tighten it with the two-pin
spanner (see " Quick-clamping nut
page 26).
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-

The low-vibration auxiliary
handle (32) reduces vibra-

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 (10). If the
O-ring is missing or damaged, the mounting
flange (10) must be replaced before operation
can resume.
Quick-clamping nut
To change the abrasive tool easily without having to use any
additional tools, you can use the quick-clamping nut (16) in-
stead of the clamping nut (15).
The quick-clamping nut (16) may be used only for
u
grinding or cutting discs.
Only use quick-clamping nuts (16) that are in good work-
ing order and not damaged.
When screwing on, make sure that the printed side of the
quick-clamping nut (16) is not facing the grinding disc;
the arrow must be pointing towards the index mark (33).

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.
Press the spindle lock but-
ton (2) to lock the grinding
spindle. To tighten the
quick-clamping nut, turn
the grinding disc firmly
clockwise.
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.
