Note: The encoding keys on the protection guard 9 ensure

that only a protection guard that fits the machine type can be

mounted.

Protection Guard for Cutting

f For cutting with bonded abrasives, always use the pro-

tection guard for cutting 15.

f Provide for sufficient dust extraction when cutting

stone.

The protection guard for cutting 15 is mounted in the same

manner as the protection guard for grinding 9.

Cutting Guide with Dust Extraction Protection Guard

The cutting guide with dust extraction protection guard 25 is

mounted in the same manner as the protection guard for

grinding 9.

Auxiliary Handle

f Operate your machine only with the auxiliary handle 6.

Screw the auxiliary handle 6 on the right or left of the machine

head depending on the working method.

Hand Guard

f For operations with the rubber sanding plate 18 or with

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

hand guard 17.

The hand guard 17 is fastened with the auxiliary handle 6.

Mounting the Grinding Tools

f Before any work on the machine itself (e. g. mainte-

nance, tool change, etc.) as well as during transport

and storage, remove the battery from the power tool.

There is danger of injury when unintentionally actuating

the On/Off switch.

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 7 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

12 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

10. If the O-ring is missing or dam-

aged, the mounting flange 10 must be

replaced before resuming operation.

Flap Disc

f For operations with the flap disc, always mount the

hand guard 17.

Rubber Sanding Plate

f For operations with the rubber sanding plate 18, al-

ways mount the hand guard 17.

See graphics page for the mounting sequence.

Screw on the round nut 20 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 17.

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.

Quick-clamping Nut

For convenient changing of grinding tools without the use of

additional tools, you can use the quick-clamping nut 13 in-

stead of the clamping nut 12.

f The quick-clamping nut 13 may be used only for grind-

ing or cutting discs.

Use only a flawless, undamaged quick-clamping nut 13.

When screwing on, pay attention that the side of the

quick-clamping nut 13 with printing does not face the

grinding disc; the arrow must point to the index mark 27.

Lock the grinder spindle with

the spindle lock button 1. To

tighten the quick-clamping

nut, firmly turn the grinding

disc in clockwise direction.
