u
Do not operate your power tool without the side
handle
(9)
.
Screw the side handle
(9)
on the left or right of the machine
head depending on how your are working.
Low-vibration auxiliary handle
The low-vibration auxiliary
handle reduces vibration,

Fitting the abrasive tools
u
Remove the battery from the power tool before carry-
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage.
There is risk of injury
from unintentionally pressing the on/off switch.
u
Do not touch grinding and cutting discs until they have
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

before clamping and releasing the abrasive tools.
u
Do not press the spindle lock button while the grind-
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 grinding tools. The
mounting hole diameter must fit the mounting flange without
play. Do not use reducers or adapters.
When using diamond cutting discs, pay attention that the
direction-of-rotation arrow on the diamond cutting disc and
the direction of rotation of the machine (see direction-of-ro-
tation arrow on the machine head) agree.
See graphics page for the mounting sequence.
To fasten the grinding/cutting disc, screw on the clamping
nut
(13)
and tighten with the two-hole spanner.
u
After fitting the abrasive tool, check that the abrasive
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.

u
Always fit the hand guard
(19)
when working with the
cup brush or disc brush.
See the graphics page for fitting instructions.
The cup brush/disc brush must be screwed onto the grinding

at the end of the grinding spindle thread. Tighten the cup
brush/disc brush with an open-ended spanner.
Carbide Grinding Head
u
A grinding head may be used only with a suitable pro-
tective guard.
Approved abrasive tools
You can use all the abrasive tools mentioned in these operat-
ing instructions.
The permissible speed [min
-1
] 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.
