General maintenance
Before carrying out any maintenance, unplug the mains supply cable.
No internal part of the Gravograph machine requires user intervention : general maintenance is limited to external cleaning.
If necessary, the user can change the belt.
If you wish to have the inside of your machine cleaned, contact a Gravograph technician.
The mains cable should always be replaced if it is damaged in any way : flattened,
nicked, cracked etc..., or if there are bare wires.
