• Do not use any grease other than those shown in Table 34.
(4) Supply and Discharge of Grease (Refer to Fig.30 Construction on page 35)
Replenish the new grease from the grease nipple during the operation.
(Replenishing grease while BEIER is nonoperational may cause insufficient grease exchange.)
(1) Interval
• Excessive grease may cause temperature rise of the bearing or leakage of the grease.
• Do not extend the replenishing interval by supplying more than the prescribed amount of grease.
• Omitting to replenish grease at the start or periodically may result in abnormal abrasion, noise, and breakage of the
bearing.
