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 13 or with

hand guard 12.
The hand guard 12 is fastened with the auxiliary handle 4.
Mounting the Grinding Tools
 Before any work on the machine itself, pull the mains
plug.
 Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot while
working.
Clean the grinder spindle 5 and all parts to be mounted.
For clamping and loosening the grinding tools, lock the grind-
er spindle with the spindle lock button 2.
 Actuate the spindle lock button only when the grinder
spindle is at a standstill. Otherwise, the machine may be-
come 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 di-
rection-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. Make sure that the grinding
tool does not graze against the protection guard or oth-
er parts.
Flap Disc
 For operations with the flap disc, always mount the
hand guard 12.
Rubber Sanding Plate
 For operations with the rubber sanding plate 13, al-
ways mount the hand guard 12.
See graphics page for the mounting sequence.
Screw on the round nut 15 and tighten with the two-pin span-
ner.
