Dismounting the Clamping Assembly
(seefi gureA)
Press the spindle lock button to lock the grind-
ing spindle.
► Actuate the spindle lock button only
when the grinder spindle is at a stand-
still. Otherwise, the machine may become
damaged.
Loosen the clamping nut with the two pin
spanner and unscrew the clamping nut.
Remove the spacer discs and the mounting
fl ange.
Clean the grinder spindle and all parts to be
mounted.
Determining the Slot Width
The slot width results from the amount of
spacer discs between the two diamond cutting
discs and the cutting width of the diamond
cutting discs.
The slot width is calculated as follows:
Slot width:Thickness of the spacer discs+
width of the diamond cutting discs.
The machine can be operated with one or two
diamond cutting discs.
Mounting the Clamping Assembly (seefi g-
ureA)
Set the mounting fl ange onto the grinder spin-
dle. The mounting fl ange with its driving fea-
ture must be properly seated on the grinding
spindle.
Place the diamond cutting disc and the spacer
discs on the mounting fl ange.
► Regardless of the requested slot width,
all spacer discs provided must always
be mounted. Otherwise, the diamond cut-
ting disc can become loose during opera-
tion and lead to injuries.
At least one spacer disc must be mounted be-
tween two diamond cutting discs.
When mounting the diamond cutting discs,
ensure that the direction-of-rotation arrows
on the diamond cutting discs match with the
rotation rotation direction of the machine (see
direction-of-rotation arrow on the gear case).
Press the spindle lock button to lock the grind-
ing spindle. Screw on the clamping nut and
tighten it with the two pin spanner.
When working with 2 diamond cutting discs,
always replace them in pairs. See graphics
page for the mounting sequence.
Note: The mounted diamond cutting discs
protrude out of the protection guard, even at
the least preselected cutting depth. Therefore,
never set down the machine on the chaser
rollers, but always aside.
Operation
Preselecting the Cutting Depth
► The cutting depth may only be prese-
lected when the machine is switched
off .
Loosen clamping lever and adjust the desired
cutting depth according to the cutting-depth
scale. Afterwards, tighten clamping lever
again.
Starting Operation
►
Observe correct mains voltage! The
voltage of the power source must
agree with the voltage specifi ed on the
nameplate of the machine. Power tools
marked with 230V can also be operated
with 220V.
Switching On and Off
► Before starting the machine, place the
power tool in such a manner on both
rear chaser rollers 3 that the diamond
cutting discs do not touch the work-
piece. Otherwise, the diamond cutting
discs can touch the workpiece, resulting in
possible loss of control over the power tool
when switching on.
To start the power tool, press the anti-lock
button fi rst and press on/off switch.
To turn off the power tool, release the pow-
er switch.
► Never set down a coasting machine on
the chaser rollers 3, but always aside,
so that the diamond cutting discs can
rotate freely and do not face toward
your body.
► Check the diamond cutting discs before
use. The diamond cutting disc(s) must
be mounted properly and be able to
rotate freely. Carry out a test run for at
least one minute without any load. Do
not use diamond cutting discs that are
damaged, out-of-balance, or vibrate.
Damaged diamond cutting discs can rup-
ture and lead to injuries.
Reduced starting current
The electronic reduced starting current limits
the power consumption when switching the
tool on and enables operation from a 13 am-
pere fuse.
Overload Protection
When overloaded, the motor comes to a stop.
Relieve the load on the machine immediately
and allow to cool down for approx. 30 sec-
onds at the highest no-load speed.
Restarting Protection
The restarting protection feature prevents un-
