2.2 LUBRICATION
CAUTION!
1.Lubrication: During parts replacement
2.Kinds of oil: FLOIL
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 optional operating condition, periodically clean the machine and apply the proper kind of oil to each part in which lubrication is needed.
Although the frequency of lubrication varies according to how often the machine is used, as a minimum it is necessary to lubricate before any part becomes dry. It is also necessary to wipe off excessive oil or it will collect dirt.
