Assembly
Mounting the Protective Devices
Before any work on the machine itself, pull
the mains plug.
Note: After breakage of the grinding disc during oper-
ation or damage to the holding fixtures on the protec-
tion guard/power tool, the machine must promptly be
sent to an after-sales service agent for maintenance.
Protection Guard for Grinding
Place the protection guard 7 on the spindle collar. Adjust
the position of the protection guard 7 to the require-
ments of the operation. Lock the protection guard 7
tightening the locking screw 6 with an allen key 3.
Adjust the protection guard 7 in such a man-
ner that sparking is prevented in the direc-
tion of the operator.
Note: The encoding keys on the protection guard 7
ensure that only a protection guard that fits the
machine type can be mounted.
Protection Guard for Cutting
For cutting with bonded abrasives, always
use the protection guard for cutting 13.
Provide for sufficient dust extraction when
cutting stone.
The protection guard for cutting 13 is mounted in the
same manner as the protection guard for grinding 7.
Cutting Guide with Dust Extraction Protection
Guard
The cutting guide with dust extraction protection
guard 20 is mounted in the same manner as the pro-
tection guard for grinding 7.
Auxiliary Handle
Operate your machine only with the auxiliary
handle 4.
Screw the auxiliary handle 4 on the right or left of the
machine head depending on the working method.
Hand Guard
For operations with the rubber sanding plate
16 or with the cup brush/wheel brush/flap
disc, always mount the hand guard 15.
The hand guard 15 is fastened with the auxiliary han-
dle 4.
Mounting the Grinding Tools
Before any work on the machine itself, pull
the mains plug.
Grinding and cutting discs become very hot
while working; do not touch until they have
cooled.

Clean the grinder spindle 5 and all parts to be
mounted.
For clamping and loosening the grinding tools, lock
the grinder spindle with the spindle lock button 1.
Actuate the spindle lock button only when
the grinder spindle is at a standstill. Other-
wise, the machine may become damaged.
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-rotation arrow on the machine head)
agree.
See graphics page for the mounting sequence.
To fasten the grinding/cutting disc, screw on the
clamping nut 10 and tighten with the two-pin spanner;
see Section "Quick-clamping Nut ".
After mounting the grinding tool and before
switching on, check that the grinding tool is
correctly mounted and that it can turn freely.
Make sure that the grinding tool does not
graze against the protection guard or other
parts.
An O-ring (plastic part) is inserted
in the mounting flange 8 around the
centring collar. If the O-ring is
missing or is damaged, it must
in all cases be replaced (article
number 1 600 210 039) before
the mounting flange 8 is mounted.
Flap Disc
For operations with the flap disc, always
mount the hand guard 15.
Rubber Sanding Plate
For operations with the rubber sanding plate
16, always mount the hand guard 15.
See graphics page for the mounting sequence.
Screw on the round nut 18 and tighten with the two-
pin spanner.
Cup Brush/Disc Brush
For operations with the cup brush/wheel
brush, always mount the hand guard 15.
See graphics page for the mounting sequence.
The cup brush/disc brush must be able to be screwed
onto the grinder spindle until it rests firmly against the
grinder spindle flange at the end of the grinder spindle
threads. Tighten the cup brush/disc brush with an
open-end spanner.
