8. Filling and replacing lubricating oil
Lubrication is a crucial factor for maintaining the operating life of your SANDEX unit.
These units feature a high level of precision, and a resistance to friction. However, improper
lubrication can reduce the life of the unit. When filling the unit with oil, make sure to prevent foreign
particles such as drilling chips, dust, or water from entering the unit.
Before filling with new oil, clean the area around the oil filling port. Also, always use clean fresh oil.
8.1 Refilling lubricating oils
(1) To add lubricating oil, remove the oil fill plug. (On standard drives, this plug is a
hexagonal PT plug and has a small air-bleeding hole in it.) Allow sufficient time for
the oil to settle in the housing for an accurate filling.
(2) On standard SANDEX units, the oil fill level and drain plugs are designed so not to
protrude from the mounting plane. However, operation at high speeds may cause oil
to spurt from the air-bleeding hole in the plug. Also, it may be difficult to refill and
drain oil if a table is mounted on the output shaft.
8.2 Oil replacement schedule
First time After 1000 hours of operation
Thereafter Every 3000 hours of operation
Note
For use under the above hours, replace once every year.
