3-3 Oil filling and draining
■ Never mix different types of oil. Failure to follow this could result in adverse effect due to the change in oil quality.
■ Oil leakage could result in accidents. Wipe away oil spills at the time of filling or draining.
[ For the speed change section ]
■ Add oil up to the specified level of the oil gauge when the speed drive stops.
Note : Continuing operation with insufficient oil could result in damage to internal parts.
Check the oil level every day.

Vertical
type
(200B, 400B, 750, 11K, or larger models)
Note : For the vertical type, be sure to set the unit vertically before adding oil. If oil
is added with the unit placed horizontally, the amount of oil will differ, and proper
lubrication management cannot be performed. If oil has been added excessively, remove
the drain plug, and drain out surplus oil to adjust the amount.
Note : Before adding oil in the vertical type of models 200B to 1500, be sure to remove the attached pressure relief plug for lubrication, which can be used to release the internal air pressure.
After adding oil, attach the pressure relief plug.

[For the speed reduction section]
■ The plug position in the center of the speed reduction section indicates
the proper oil level. Remove the upper lubrication plug and level plug, and
fill with oil until oil flows out of the level plug.

■ For the grease lubricated system <Frame A/B/C of N(G)11 to 71>,
additional refill is not required in the middle of the replacement interval.
When replacing oil, disassemble the unit for overhaul before lubrication.
