For lapping operation, make sure that sufficient lapping paste is put onto the sur-
face to be machined.
For grinding operation, make sure that the abrasive is still in proper condition.
Always change abrasives in time, otherwise it might result into poor performance:
• Poor performance: wasted time
• Overproportional heat creation: shearing off the abrasives and damag-
ing the valve seat

HANGE OF ABRASIVES
• Stop the machine with trigger button (electric drive) or with red safety
button on maintenance unit (pneumatic drive) and interrupt the power
supply.
• Release grinding pressure. To release grinding pressure, untie the flap
of the centre module and move machine arm up by using the ratchet of
the in-feed mechanism until the indicator on top of the upper gear hous-
ing does not indicate any grinding pressure anymore.
• Disconnect machine from power supply
• Hold machine arm and open the flap of the centre module
• Move the machine arm to the side and take the bracket out of the in-
feed mechanism
• Move machine arm up until the planet wheel can be taken out of the
valve body
• Change the abrasive
• Put machine back into position, adjust grinding pressure and go on with
the grinding operation (steps vice versa as described above)

HANGE OF DRIVE MOTOR
CAUTION
The valve grinder may only be used with the original drive
motors delivered with the machine.
Otherwise, due to higher speeds and torque or wrong
mechanical connections, the machine can be damaged and it
may result into harm to the operator.
