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.
