Fitting the Abrasive Tools
Remove the battery from the power tool before carry-
u
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.
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 (27) 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 (25) 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 (18) and the quick-clamp-
ing nut (25), the use of intermediate layers is not necessary.
To secure the grinding/cutting disc, place the mounting
flange with O-ring (18) on the grinding spindle (27) and
screw on the quick-clamping nut (25).
Only use the quick-clamping nut (25) for grinding/cutting
discs up to a maximum diameter of 150 mm.
The quick-clamping nut (25) may be used only for
u
grinding or cutting discs.
Only use quick-clamping nuts (25) 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 (25) is not facing the grinding
disc.
Always secure a grinding/cutting disc using only the
u
quick-clamping nut (25) supplied.

A plastic part (O-ring) is fitted around the cent-

O-ring is missing or damaged, the mounting
flange (18) must be replaced before operation

After fitting the abrasive tool, check that the abrasive

other parts.

Quick-clamping nuts (25)
that are properly secured
and not damaged can be re-
moved 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 – always use a two-
pin spanner.
After fitting the mounting
flange and the grinding/cut-
ting disc, the free thread
length of the grinding
spindle must be at least
4 mm.
