The brake release switch affects both
Joints #3 and #4. When the brake release
switch is pressed, the brakes for both Joints
#3 and #4 are released simultaneously.
Be careful of the shaft falling and rotating
while the brake release switch is being
pressed because the shaft may be lowered
by the weight of the end effector.
(3) Turn OFF the Controller.
(4) Wipe off the old grease from the shaft, and
then apply new grease to it.
Grease application range is from the end of
the spline nut to mechanical stop.
