When temporary fixing the Joint #5 motor unit, make sure that the motor unit can be
moved by hand and does not tilt when being pulled. If the unit is fixed too loose or
too tight, the belt will not have proper tension.

Regarding belt tension:
-
Jumping (position gap) may occur if the value is below the lower limit.
-
Vibration (abnormal noise) or reduction of life of the parts may occur if the
value exceeds the upper limit.
When using belt tensile jig (maintenance part):
1.
Install the hexagon socket set screws (M3×20) to
the holes on inscribed side of “5” on the belt
