WARNING
Handling gearbox oil involves several
safety risks, see Gearbox lubricants (oil or
grease) on page 30.
CAUTION
The gearbox can contain an excess of
pressure that can be hazardous. Open the
oil plug carefully in order to let the excess
pressure out.
Open the oil plugs, one for filling and the
other for venting.
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.
Refit the oil plugs.
