Electric Connection; Switch On/Off - HOLZMANN MASCHINEN DSM 150 Mode D'emploi

3 ELECTRIC CONNECTION

Do not operate the machine at non-protected circuit, the power socket must be
fused as well:
DANGER OF ELECTROCUTION!
The connection of the machine to the electric power supply and the following checks are to be
carried out by respectively trained personnel.
The electronic connection of the machine is designated for operation with a grounded power
socket!
The connector plug may not be manipulated.
If the connector plug doesn't fit or if it is defect, only qualified electricians might modify or renew
it!
The grounding wire should be held in green-yellow.
A damaged cable has to be exchanged immediately!
Check, whether the feeding voltage and the Hz comply to the required values of the machine. A
deviation of feeding voltage of ±5% is allowed (e.g.: a machine with working voltage of 380V can
work within a voltage bandwidth of 370 till 400V.
4 OPERATION

4.1 Switch ON/OFF

You can switch the machine On and Off with the ON/OFF Switch (6).
4.2 Grinding
Grinding is a science for itself! Different metal alloys, profile types, the correct grinding angle
as well as the material and grain of the grinding disc and the grinding speed have a decisive
impact on grinding results. Each steel type requires an optimized grinding stone for best re-
sults.
As a rough rule of thumb, single and multiply alloyed steel can be grinded with aluminium ox-
ide grinding stones with granularity K 80.
For grinding the blades of axes, pickaxes, spades etc. an aluminium oxide stone with granu-
larity 40-60 can be sufficient.
We strongly advice you to invest in good technical literature, containing tables, important ad-
vices regarding the grinding process ...
4.3 Operation advices
Let the grinding stone come to full speed before beginning the grinding process.
Do not overload the machine! A good approach to know when you overload the machine:
When the grinding stone looses speed due to workpiece pressure.
DO NOT USE THE MACHINE FOR ANY KIND OF CUTTING OPERATIONS!
Make it a habit to operate the machine in a position standing slightly next to the machine and
not exactly in front oft he grinding stone.
Always check the tightening knobs of the tool rest if tightened well.
