8. Alternate method of lifting:
Fit the lifting device 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 hoising block is used to balance the
upper arm.
See the lifting instructions!
NOTE!
The brake on axis 3 shall be released
during the lift, until the roundsling
between the wrist and the frame transfers
the load of the frame!
See figure!
Art. no. is specified in Required equipment on
page 166.
Make sure the lift is done completely level!
How to adjust the lift is described in the
enclosed instruction to the lifting device!
Follow the instructions before lifting!
Releasing the brakes is detailed in section
Manually releasing the brakes on page 61.

10.
CAUTION!
The complete arm system weighs 590 kg!
All lifting equipment used must be sized
accordingly!
11 . Lift the arm system carefully and secure
it in a safe area.
Always move the robot at very low
speeds, making sure it does not tip.
Continue lifting even if the arm system
turns out to be unbalanced despite earlier
adjustments! The risk of damaging the
interfaces is bigger if the load is lowered
unbalanced!
Make sure all hooks and attachments stay in
the correct position while lifting the arm
system and that the lifting device does not
wear against sharp edges.
