Action
Unscrew the M16x110 screws (18 pcs) that
secure the gearbox to the frame.
Tip
This procedure is best done with two per-
sons working together:
• Person one: working under the base,
holding the torque wrench in place,
and making sure the bit is correctly
fitted.
• Person two: working beside the ro-
bot, working with the torque wrench.
With lifting accessories stretched, unscrew
the M16x70 screws (18 pcs) that secure
the cross roller bearing to the frame.
Tip
This procedure is best done with two per-
sons working together:
• Person one: working under the base,
holding the torque wrench in place,
and making sure the bit is correctly
fitted.
• Person two: working beside the ro-
bot, working with the torque wrench.
Make sure that all screws have been re-
moved and that the lifting accessories are
fastened correctly.
Action
Prepare an area where to put down the arm
system after removal. Use for example two
wooden planks on which the flange can
rest.
The screw heads of the cross roller bearing
will stick out further down than the outer
flange, so if placing down the arm system
on a flat surface, the arm system will rest
on the screw heads and be unstable.
