Auxiliary Handle
Operate your machine only with the auxiliary
handle 3.
Screw the auxiliary handle 3 on the right or left of the
machine head depending on the working method.
Hand Guard
For operations with the rubber sanding plate
12 or with the cup brush/wheel brush/flap
disc, always mount the hand guard 11.
The hand guard 11 is fastened with the auxiliary handle
3.
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 4 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. Otherwise, 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 9 and tighten with the two-hole spanner.
After mounting the grinding tool and before
switching on, check that the grinding tool is
correctly mounted and that it can turn freely.
An O-ring (plastic part) is inserted in
the mounting flange 7 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 7 is mounted.

dle 4. Screw on the clamping nut 9 and tighten with the
two-pin spanner.
Rubber Sanding Plate
For operations with the rubber sanding plate
12 or with the cup brush/wheel brush/flap

grinder spindle flange at the end of the grinder spindle
threads. Tighten the cup brush/disc brush with an
open-end spanner.
