the grinding dust with a seperate extraction system and
to prevent deposition of dust in the tubes.
Alternating grinding of spark arcing and non-spark
arcing materials is only permitted on especially fur-
nished grinding equipment. The grinding equipment
must be provided with seperate grinding areas and
extraction systems for the different dusts. In addition
particular maintenance and purging intervals have to
be observed. Grinding equipment for alternating grin-
ding must be flagged accordingly.
Information on particular protective measures neces-
sary for the grinding of aluminium and its alloys
can be given at the competent offices of Technical
Control of the respective German employer´s liability
insurance associations. Details can also be viewed
in the „Richtlinien zur Vermeidung der Gefahr von
Staubbränden und Staubexplosionen beim Schleifen,
Bürsten und Polieren von Aluminium und seinen
Legierungen" (guidelines for reporting the dangers of
dust fires and dust explosions when grinding, brushing
or polishing aluminium and its alloys) (ZH 1/32).
5.0 Delivery, transport, handling and
storage
ATTENTION! Always check delivery for complete-
ness and damage!
The carrier (forwarder or railway) is to be informed
immediately in case of transport damages.
(cf. yellow label).
The machine is packed on pallet, it has to be transpor-
ted by forklift or truck. The packed machines are no
staple commodities!.

6.0 Setting up the machine

The grinding machine should be placed on a level
surface and screwed with 4 screws. Check that the belt
moves freely and is not impeded in any way.
7.0 Installation
Please check whether type of current, current voltage
and fusing agree with the prescribed values. There
must be a protective earth terminal. Mains fusing 10
A. For connecting the machine we recommend the
cable No.:488761 or No.: 488762 (230V)

8.0 Belt tracking

When first starting the machine, the belt will not run
centrally on the contact wheel. This is corrected by
turning the star knob screw:
Clockwise - belt moves towards the left,
Anticlockwise - belt moves towards the right.

9.0 Changing the belt

Ensure that the machine is stopped completely!
a. Remove screw (73) and open door (75),
b. Remove the spark trap,
c. Slaken the belt by turning the clamping lever,
d. Replace the belt,
Attention! Be sure of correct direction of rotation.
e. Tighten the belt by turning the star knop screw,
f. Close the door (75), thighten the screw and fit the
spark trap.

10.0 Contact grinding

Normal grinding, grinding against the contact wheel
with removed covers.
11.0 Surface grinding
Open the cover and push the workpiece hardly against
the graphit grinding base (24).
12.0 Height and angle adjustment
Height and angle of the machine can be adjusted to the
most comfortable position by loosening the screws (2)
and retightening.

13.0 Maintenance

Ensure that all moving parts are kept clean and that
the belt is in good condition. Never use a badly worn
or torn belt.
14.0 Exhausting
For continuous operation a dust exhaust system is
necessary!
(exhaust system capacity for MBG 75 min. 400 m
exhaust system capacity for MBG 150 min. 600 m
15.0 Edges and deburring device
Disassemble the grinding bearing surface (43). The
edges and deburring device are fastened with the same
fastening elements (guide pin and clamping lever) of
the grinding bearing surface.
You can change the land size by loosening of the
clamping lever and by gradually shifting the device in
the elongated hole area from 0-45° to 4-45°.
