Approved Grinding Tools

All grinding tools mentioned in these operating

instructions can be used.

The permissible speed [min

-1

] or the circumfer-

ential speed [m/s] of the grinding tools used

must at least match the values given in the table.

Therefore, observe the permissible rotational/

circumferential speed on the label of the grind-

ing tool.

Dust/Chip Extraction

f Dusts from materials such as lead-containing

coatings, some wood types, minerals and

metal can be harmful to one’s health. Touch-

ing or breathing-in the dusts can cause aller-

gic reactions and/or lead to respiratory infec-

tions of the user or bystanders.

Certain dusts, such as oak or beech dust, are

considered as carcinogenic, especially in

connection with wood-treatment additives

(chromate, wood preservative). Materials

containing asbestos may only be worked by

specialists.

– Provide for good ventilation of the work-

ing place.

– It is recommended to wear a P2 filter-

class respirator.

Observe the relevant regulations in your

country for the materials to be worked.

Operation

Starting Operation

f Observe correct mains voltage! The voltage

of the power source must agree with the

voltage specified on the nameplate of the

machine. Power tools marked with 230 V

can also be operated with 220 V.

Switching On and Off

To start the machine, push lock-on button 8 to-

ward the front and then press the On/Off switch

To lock the pressed On/Off switch 7, push the

lock-on button 8 further toward the front.

To switch off the power tool, release the On/Off

switch 7, or when it is locked, briefly press the

On/Off switch 7 and then release it.

f Check grinding tools before using. The

grinding tool must be mounted properly

and be able to move freely. Carry out a test

run for at least one minute with no load. Do

not use damaged, out-of-centre or vibrating

grinding tools. Damaged grinding tools can

burst and cause injuries.

Speed preselection (GPO 12 E)

The required speed can be preselected with the

thumbwheel 6 (also while running).

The required speed depends on the material

and the working conditions and can be deter-

mined through practical testing.

Working Advice

f Clamp the workpiece if it does not remain

stationary due to its own weight.

f Do not strain the machine so heavily that it

comes to a standstill.

f After heavily straining the power tool, con-

tinue to run it at no-load for several minutes

to cool down the cutting/grinding tool.

For sanding applications on soft materials, e. g.,

gypsum or paint, it is recommended to use the

rubber sanding plate 17 with sanding disc 18.

Cup brushes 21 and wheel brushes are suitable

for rust removal.
