Action
With all screws in position, lower the gearbox
carefully down against the base with guid-
ance from the guide pins.
Lower the lifting accessory so that the chain
is no longer stretched.
Fit the attachment screws that secure the
gearbox to the base, from underneath.
Remove the guide pins and fit the two remain-
ing screws.
Secure the attachment screws.
Tip
This procedure is best performed by two
persons working together:
• one underneath the robot base making
sure that the bit is being fitted into the
screw head holes, all the way until they
reach the bottom
• one using the torque wrench, tighten-
ing the screws from beside the base.
Check the protection tube for damages.
Especially inspect the surface for the sealing
ring.
Replace if damaged.
Wipe the surfaces of the protection tube and
the hole in axis-1 gearbox clean from any
contamination.
Put some grease on the protection tube.
