Action
Alternate method of lifting:
Fit the lifting accessory and a
roundsling on the upper arm and
a roundsling with a hoisting
block, to the wrist unit.
Also fit a separate roundsling
between the wrist and the frame
in order to eliminate any load
through the brake on motor axis
3.
The hoisting block is used to
balance the upper arm.
See the lifting instructions.
Note
The brake on axis 3 shall be re-
leased during the lift, until the
roundsling between the wrist
and the frame tranfers the load
of the frame.
See figure to the right!
Remove the mechanical stop pin
from the frame.
