Cleaning the high current connection contacts
Regularly clean all contact points (current transfer
points) between the high current transformer, the
high-current cable, the high-current switch and the
magnetisation units.
1. High current connection
2. Contact
Procedure
1. Turn the machine off and secure it against being
inadvertently turned on.
2. Release the connections on the high current cables.
3. Clean the contact surfaces with medium-fine steel
wool until they are shiny.
4. Apply a thin layer of Tungrease VC563 contact
grease to the contact surfaces.
5. Reconnect the cables.
Maintenance of the magnetising coil
Heavy contamination of the linear guides on the mag-
netising coil can lead to increased wear. Clean and
grease the guides regularly. If the coil is no longer run-
ning smoothly, replace the guides.
Lubricate the coil's drive chain regularly.
Prerequisites
• Contact grease Tungrease VC563
• Chain grease
• A soft cloth and some industrial cleaner
Procedure
1. Remove the workpiece from the machine.
2. Move the coil into left-most position.
3. Turn the machine off and secure it against being
inadvertently turned on.
4. Soak a soft cloth with industrial cleaner. Do not
use acids or alkalines.
5. Rub the guide shaft with the cloth down. Do not
use metal tools for cleaning.
6. Apply a thin coat of contact grease to the shaft
7. Move the coil to the right-most position.
8. Clean the rest of the guide shaft.
9. Apply a thin coat of contact grease to the rest of
the shaft
10. If present: grease the coil's drive chain using a
brush.
11. If necessary, tighten the drive chain at the chain
tensioner on the right side of the base frame.
Adjusting the safety clutch of the magnetisation coil
The safety clutch in the transport unit of the magnetisa-
tion coil fulfills an important safety function. The coil is
driven by an electric motor over the workpiece; if any
part of the body gets caught between the workpiece
and the coil, the safety clutch disconnects the drive.
1. Drive motor for coil transport
2. Screws of the motor housing cover
3. Safety clutch.
Procedure
1. Turn the machine off and secure it against being
inadvertently turned on.
2. Open the chain drive housing. Undo the 4 screws
and remove the cover.
3. Check the adjustment of the clutch and adjust if
necessary.
4. Replace the cover and close the drive housing.
5. Check the function of the clutch. The safety clutch
should disconnect the drive if it encounters even a
small amount of resistance.
