Lubrication

CAUTION!

1.Lubrication: During parts replacement

2.Kinds of oil: FLOIL G-488: 1kg can (part No.: 19454906001)

Any machine is generally in its best condition when delivered; therefore, it is necessary to try to keep this condition. Unexpected failure occurs due to lack of oil, debris, or dust. To keep its best condition, periodically clean the machine and apply proper kinds of oil to each part in which lubrication is needed. Although the frequency of lubrication varies according to how much the machine is used, at least it is necessary to lubricate before the machine becomes dry. It is also necessary to wipe off excessive oil as it collects dirt.

NOTE: Before replacing the important parts, store the printer parameter data on a PC with the B-EV4 setting tool. Uploading the data from the PC to the printer after replacement restores the printer parameter setting to the status prior to replacement. Regarding the details of B-EV4 setting tool, refer to the B-EV4 Setting Tool Specification posted on the Barcode Knowledge Pot.
