out and fall down before the lifting access-
ory is applied, if pulled out to far.
CAUTION
The axis-3 gearbox weighs 56 kg.
All lifting accessories used must be sized
accordingly.
Apply the lifting accessory to the gearbox.

There will be some oil spill when the gear-
box is removed. Put some oil absorbent

cessory, remove the gearbox by letting it
slide out on the guide pins.
