Action
Leave one of the remaining attachment
screws fitted, remove the other screws.
Action
Note
Make sure the lift is done completely
leveled! In case of necessary adjustments,
use the shortening loops on the lifting ac-
cessory (chain), and make sure to place
the chain the right way through the loops.
Remove the remaining attachment screw
and let the upper arm slide out from the
lower arm with support from the guide pins.
Lift the upper arm and place it on the pre-
pared area.
CAUTION
Only valid when the upper arm is removed
due to replacement of the axis-3 gearbox:
If the cable harness is still fitted or partly
fitted, use caution when lifting the upper
arm over to the other side of the robot, in
order not to cause any damage to the cable
harness.
