This chapter describes hydraulic oil and lubricant. The description on hydraulic oil and lubricant (this
chapter) in this document should be reflected at least to the operation manual for the customer’s machine
into which GM is incorporated.
CAUTION
• When replacing the hydraulic oil and lubricant, turn off the power to the customer machine.
• GM may become hot during operation. After stopping the operation, do not touch GM until it
has cooled down. If the oil filler port and oil drain port are unplugged in the high-temperature
state, the high-temperature lubricant may blow out accidentally due to the pressure change
in the reduction gears, which can cause burn injury.
NOTICE
• GM is filled with the lubricant at the factory. Filling up the lubricant excessively may result in
heat generation and leakage of the lubricant.
• GM is drained hydraulic oil at the time of shipment. Be sure to fill the motor casing with
hydraulic oil before operation.
• If the amount of the lubricant has decreased due to some reason, identify and remove the
cause, and then add the lubricant.
• When draining the lubricant, do not drain it on the ground. Be sure to drain it into a container.
Disposal of the waste oil should be in accordance with the applicable laws and regulations.

• Be sure to wear rubber gloves to prevent hydraulic oil and lubricant from contacting your skin.
