Fitting grinding or cutting discs
Use only grinding or cutting discs that are approved for use at the maximum per-
mitted no-load speed of the tool.
First, place the clamping flange (8) on the spindle (6) as shown in the illustration.
Place the diamond cutting disc or abrasive cutting / grinding disc (9) on it.
Screw on the clamping nut (10).
An O-ring is located around the centering collar
of the clamping flange (8). If the O-ring is damaged
or missing, it is essential that it is replaced before
the clamping flange (8) is fitted.
Prevent movement of the spindle by pressing the spindle lockbutton (4).
Press the spindle lockbutton (4) only when the spindle has stopped rotating.
Use the pin wrench (12) to tighten the clamping nut (10).
Check that the grinding / cutting disc can rotate freely before switching on the tool.
Testing the grinding / cutting disc:
Please refer to "Initial operation".
Please note
The mains voltage must conform to the specifications printed on the rating plate of
the tool. Tools designed for 230 V may also be connected to a 220 V power source.
Kwik-lock clamping nut (accessory)
The Hilti Kwick-lock clamping nut can be used for fitting the grinding / cutting disc.
The Kwick-lock nut (11) is used instead of the standard clamping nut (10). This per-
mits grinding / cutting discs to be changed without the use of a tool.
Note: The Kwick-Lock nut cannot be used with cup wheels, brushes, rubber back-
ing discs, tuck pointing discs and diamond cup wheels.
Clean the clamping flange (8) and Kwik-lock clamping nut (11).
Check the Kwik-lock clamping nut before it is
fitted: The arrow (A) on the top surface must be
positioned within the index marks (B). If the
Kwik-lock nut is tightened without first check-
ing that the arrow is located within the index
marks, it will no longer be possible to release it
by hand. In this case, release the Kwik-lock nut
using the pin wrench. Do not use a pipe wrench
under any circumstances.
To fit a grinding disc, clean the clamping flange
(8) and place it on the spindle, then fit the grind-
ing disc 3 (see illustration). Screw on the Kwik-
lock clamping nut as shown in the illustration
(with lettering visible after the nut is screwed
on) until it is seated against the grinding disc.
Lock the spindle by pressing the spindle lock-
button (4).
