Action
Remove all but one of the remaining attach-
ment screws that secure the lower arm to
the axis-2 gearbox.
Action
Put two foam boards, pallets or similar
protective material on the floor, somewhere
close to the robot.
Put one higher foam block as protection
for the wrist.
If needed, move axis-1 into a position that
gives the required space.
Note
Keeping the cable harness and DressPack
fitted on the robot during gearbox replace-
ment is only a recommendation. If it is not
possible to put the lower and upper arm
close enough to the robot, the cable har-
ness and DressPack in the base and in the
frame must be removed first.
CAUTION
The weight of the complete upper and
lower arm together is 535-565 kg (depend-
ing on robot variant)
All lifting accessories used must be sized
accordingly.
