Action
CAUTION
Releasing the brakes on the axis-2 motor
results in weight transfer of upper and
lower arm weight to the inserted lock screw
in the lower arm or to the attached lifting
accessories (whichever is used). If lifting
accessories are used, verify that the lifting
chains and roundslings are stretched by
raising the overhead crane, before releas-
ing the brakes.
Release the brakes on the motor with the
brake release tool, to unload the weight:
1 Turn off the brake release tool.
2 Connect the tool to the motor power
connector (MP).
3 Release the brakes by turning on the
brake release tool and pressing the
brake release button on the tool.
The power for brake release is only
applied for 180 seconds after activa-
tion.
DANGER
Handling the tool incorrectly will cause
serious injury.
Read and follow enclosed user instructions
for the tool.
WARNING
Electrical damage to the motor may occur
if 24V is supplied to the motor connector
for more than 30 seconds. Use the spe-
cified brake release tool to eliminate the
risk.
Remove the two lower screws.
Use a bits extender in order to reach the
screws.
