4. Screw the clamping nut on tightly.
5. Press the spindle lockbutton and hold it in this position.
-NOTE-
Press the spindle lockbutton only after rotation of the spindle has stopped.

dle lockbutton.
6.6 Using the Kwik-Lock quick-release clamping nut
The Kwik-Lock nut can be used instead of the standard clamping nut. No tools are
then required for changing discs.
-NOTE-
The Kwik-Lock nut cannot be used in conjunction with cup wheels, brushes, rubber
backing pads, tuck pointing discs and diamond cup wheels.
6.6.1 Using the Kwik-Lock clamping nut to fit a cutting / grinding disc
The arrow on the upper surface of the nut must be within the index marks. If the arrow
is not within the index marks when the nut is tightened, it will be impossible to release
the nut by hand. Should it be necessary, the pin wrench can be used to release the
Kwik-Lock nut (do not use pliers or a pipe wrench!).
1. Unplug the supply cord form the electric socket.
2. Clean the clamping flange and the quick-release nut.
3. Place the clamping flange on the drive spindle.
-NOTE-
An O-ring is set into a recess in the clamping flange. This O-ring must be replaced
if missing or damaged.
4. Place the diamond cutting disc or abrasive cutting / grinding disc on the clamping
flange.
5. Screw the Kwik-lock nut onto the spindle until it contacts the disc (the side with
the lettering should remain visible after the nut is screwed on).
6. Press the spindle lockbutton and hold it in this position.
-NOTE-
Press the spindle lockbutton only after rotation of the spindle has stopped.
7. Continue to tighten the nut firmly by hand in a clockwise direction until the Kwik-
Lock nut holds securely.
6.6.2 Removing a cutting / grinding disc secured with the Kwik-Lock clamping nut
1. Unplug the supply cord form the electric socket.
2. Release the Kwik-Lock nut by turning the knurled ring in a counter-clockwise direc-
tion (use the pin wrench if the Kwik-Lock nut cannot be released by hand. Do not
use pliers or a pipe wrench!).
6.7 Rotating the gearing section
To permit the tool to be used safely and without fatigue in all situations (e.g. on / off
switch facing upwards), the gearing section of the tool can be rotated, in increments
of 90°, to one of four positions.
1. Unplug the supply cord form the electric socket.
2. Clean the tool.
3. Remove the side handle from the tool.
4. Remove the four screws from the gearing section.
5. Rotate the gearing section to the desired position without pulling it away from the
tool.
6. Insert and tighten the four screws.
7. Fit the side handle.
