Mounting the Protective Devices

f

Before any work on the machine itself, pull the mains 

plug.

Note: 

After breakage of the grinding disc during operation or 

damage to the holding fixtures on the protection guard/power 

tool, the machine must promptly be sent to an after-sales 

service agent for maintenance for addresses, see section “Af-

ter-sales Service and Customer Assistance”.

Protection Guard for Grinding

Place the protection guard 

5

 on the spindle collar. Adjust the 

position of the protection guard 

5

 to the requirements of the 

operation and lock the protection guard 

5

 with the locking 

screw 

6

.

f

Adjust the protection guard 5 in such a manner that 

sparking is prevented in the direction of the operator.

Protection Guard for Cutting

f

For cutting with bonded abrasives, always use the pro-

tection guard for cutting 13.

f

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 

5

.

Cutting Guide with Dust Extraction Protection Guard

The cutting guide with dust extraction protection guard 

24

 is 

mounted in the same manner as the protection guard for 

grinding 

5

.

Auxiliary Handle

f

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

f

For operations with the rubber sanding plate 20 or with 

the cup brush/wheel brush/flap disc, always mount the 

hand guard 18.

The hand guard 

18

 is fastened with the auxiliary handle 

3

.

Mounting the Grinding Tools

f

Before any work on the machine itself, pull the mains 

plug.

f

Do not touch grinding and cutting discs before they 

have cooled down. 

The discs can become very hot while 

working.

Clean the grinder spindle 

4

 and all parts to be mounted.

For clamping and loosening the grinding tools, lock the grind-

er spindle with the spindle lock button 

1

.

f

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-pin spanner; see Section “Quick-

clamping Nut ”.

f

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.

A plastic part (O-ring) is fitted around 

the centring collar of mounting flange 

7

. 

If the O-ring is missing or damaged,

the mounting flange 

7

 must be replaced 

before resuming operation.

Flap Disc

f

For operations with the flap disc, always mount the 

hand guard 18.

Rubber Sanding Plate

f

For operations with the rubber sanding plate 20, al-

ways mount the hand guard 18.

See graphics page for the mounting sequence.
Before mounting the rubber sanding plate 

20

, put the 2 spac-

er discs 

19

 onto the grinder spindle 

4

.

Screw on the round nut 

22

 and tighten with the two-pin span-

ner.

Cup Brush/Disc Brush

f

For operations with the cup brush/wheel brush, always 

mount the hand guard 18.

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. Tight-

en the cup brush/disc brush with an open-end spanner.

Grinding Cup

f

When working with the grinding cup, mount the special 

protection guard 15.

The grinding cup 

16

 should never project further out of the 

protection guard 

15

 than necessary for the respective grind-

ing application. Adjust the protection guard 

15

 accordingly to 

this dimension.
See graphics page for the mounting sequence.
Screw on clamping nut 

9

 and tighten with two-pin spanner 

17

.

Quick-clamping Nut

For convenient changing of grinding tools without the use of 

additional tools, you can use the quick-clamping nut 

11

 in-

stead of the clamping nut 

9
