Kinds of oil: FLOIL G-488: 1Kg can. (Part No.19454906001)
3.
Do not spray the inside of the printer with lubricants. Unsuitable oil can damage the mechanism.
All machines are generally delivered in their best condition. Efforts should be made to keep them that way. Lack
of oil, or the presence of debris or dust, may cause an unexpected failure. To maintain in optimal operating
condition, periodically clean the machine and apply the proper kinds of oil to each part in which lubrication is

necessary to lubricate before any part becomes dry. It is also necessary to wipe off excessive oil or it will collect
dirt.
NOTE: Replacement procedures are partly different depending on the models.
2.1 REPLACING THE CPU PC BOARD AND THE WIRELESS LAN MODULE
For GH20/GH30 models
