is suitable for double-wheeled bench grinders. Inner 

diameter of extraction connection piece: 35 mm. 

Before switching on the machine, ensure that the 

extraction device is connected and being used 

correctly.

6.6 Test run

Check the grinding wheels before initial use. 

Test run

A test run of approx. 5 min without load must 

be carried out before initial use. All persons must 

stay clear of the danger zone when this is 

performed.

.

7.1 Adjusting the workpiece support

Adjust the workpiece supports (8) frequently to 

compensate for wear of the grinding wheels (4).
The distance between the workpiece support and 

grinding material must be as small as possible and 

never greater than 2 mm (see illustration C, page 2). 
If the grinding wheel is so badly worn that the 

maximum distance of 2 mm can no longer be 

maintained, the grinding wheel must be replaced.

7.2 Adjusting the spark deflector

Adjust the spark deflectors (10) regularly to 

compensate for wear on the grinding wheels (4).
Release the 2 screws on the spark deflector and 

shift the spark deflector.
The distance between the spark deflector and 

grinding wheel must be as small as possible and 

never greater than 2 mm (see illustration C, page 2).
If the grinding wheel is so badly worn that the 

maximum distance of 2 mm can no longer be 

maintained, the grinding wheel must be replaced.

7.3 Switching On and Off

Press the switch  (11) (see illustrations D, page 2).

I

DS 125, DS 150: 

Avoid inadvertent starts: always 

switch the grinder off when the plug is removed from 

the mains socket or if there has been a power cut. 

Restart protection (not in DS 125, DS 150):

When power is restored after a power failure, the 

machine - which is still switched on - will not start 

automatically for safety reasons. Switch machine 

on and off again.

7.4 Dry grinding, belt sanding

- Stand in front of the grinder.

- Holding the workpiece with both hands, place the 

workpiece on the workpiece supports (8) and 

gently press it against the dry grinding wheel/

sanding belt. For optimum grinding/sanding 

results, move the workpiece gently to and fro. This 

also helps to distribute wear evenly on the 

grinding material.

7.5 Wet grinding (TNS 175 only)

Only use the wet grinding wheel for grinding 

when there is water in the water container. 

(18). Roughly 1/3 of the wet grinding wheel should 

be immersed in water. grinding results may 

impaired if the water level is either too low or too 

high.
- Stand to the left of the grinder, in front of the wet 

grinding wheel.

- Holding the workpiece with both hands, lower it 

onto the wet grinding wheel. You can also support 

the workpiece on the levels on the water container 

(18) and then lower the workpiece onto the wet 

grinding wheel.

7.6 Adjusting the belt run (BS 175 only)

Unplug. Rotate the sanding belt manually. Use 

the rotary knob (14) to adjust the sanding belt 

so that it runs centrally on the sanding belt roller.

7.7 Setting the angle of the belt sanding arm 

(only BS 175) (see page 3 fig. E)

- Loosen the screw at the belt sanding arm

- Put the belt sanding arm in the desired position

- Tighten again the screw at the belt sanding arm

Clean, check and perform maintenance work on the 

machine and guard devices regularly. Regularly 

clean the inside of the grinding wheels and belt 

grinder housing. The grinding wheels and sanding 

belt must be able to rotate freely within the housing.

Disconnect the mains plug before starting any 

setting, cleaning, maintenance or repair work.

8.1 Grinding wheel change

Use only original Metabo grinding wheels.

The permissible rotational speed specified on 

the grinding wheel must be equal to or greater 

than the maximum idling speed specified on the 

identification plate of the machine.

Grinding wheel check:

suspend the grinding wheel on a thread. 

Knock lightly with a piece of hard wood. You will 

hear a clear tone if the grinding wheel is in perfect 

condition. If you hear a clattering, dull or hollow 

sound, the grinding wheel is damaged.

Do not use damaged grinding wheels.

Test run

A test run of approx. 5 min without load must 

be carried out after the grinding wheel has been
