orKing instructions
The optimal grinding results are obtained when the grind-
ing belt is steadily moved back and forth under slight
pressure. The control electronics keep the belt speed
virtually constant during idle and load conditions for as-
sured, consistent work results. Too great a pressure re-
duces machine efficiency and the grinding belt’s useful
life. The machine is equipped with an electronic control
and integrated overload protection. If the machine is over-
loaded the belt blocks briefly. Immediately remove all
loads on the machine and keep it running in the unloaded
state for a short time. Select a suitable belt speed.
When the contact pressure is too low the belt may
slip on the drive roller!

To work effectively and surely keep the
machine and the ventilation slots clean at
all times.
After approx. 150 operating hours check carbon brushes
and replace if necessary. Clean motor housing and re-
plenish grease filling in gearbox housing.
To maintain the protective insulation the machine must be
subjected to a technical safety inspection. This work must
be done exclusively by a specialized electrical workshop.
When working on metal under extreme working conditions
conductive dust deposits can occur inside the machine,
