Elimination/Action Description Warning
Make sure not to overfill the
gearbox when filling it with oil or
grease! 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.

Do not overfill
After filling, check the correct
level.
When filling gearbox oil, do not
mix different types of oil unless
specified in the instructions. Al-
ways use the type of oil specified
by the manufacturer! Mixing types of oil may cause
severe damage to the gearbox.

When changing gearbox oil, first
run the robot for a time to heat
up the oil. Warm oil drains quicker than
cold oil.

Heat up the oil
After refilling, check the lubricant
level. 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.
