Action
Open the upper oil plug.
Note
The lower oil plug has to be closed; other-
wise, the oil may leak before required oil
amount is filled.
WARNING
Overfilling of gearbox lubricant can lead to
internal over-pressure inside the gearbox
which in turn may:
• damage seals and gaskets
• completely press out seals and
gaskets
• prevent the robot from moving
freely.
Refill the gearbox with oil.
Note
The amount of oil to be filled depends on
the amount previously being drained.
CAUTION
Oil filling must be slow to make sure air
venting is fluent.
Inspect the oil level by measuring the level
at the upper oil plug hole.
Required oil level: within the range of 64
mm to 69 mm below the edge of the oil plug
hole.
CAUTION
The oil level sinks when the oil fills all cav-
ities in the gearbox. Wait until the oil stops
sinking, before measuring the oil level.
Refit the oil plug.
