Description
Overfilling of gearbox lubricant
can lead to internal over-pres-
sure inside the gearbox which in
turn may:
•
damage seals and gas-
kets
•
completely press out
seals and gaskets
•
prevent the robot from
moving freely.
Mixing types of oil may cause
severe damage to the gearbox.
Warm oil drains quicker than
cold oil.
The specified amount of oil or
grease is based on the total
volume of the gearbox. When
changing the lubricant, the
amount refilled may differ from
the specified amount, depending
on how much has previously
been drained from the gearbox.
