■Lubrication

CAUTION: 1.Lubrication: During parts replacement

2.Kinds of oil: FLOIL G-488: 1kg kan (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.
