Installation: Joint #1 Motor (M/C Cable Backward)
When tightening hexagon socket head cap bolts, refer to the 2.4 Tightening Hexagon Socket
Head Cap Bolts.
1. Put the Joint #1 timing belt on the Joint #1 pulley 2 of the Joint #1.
Hold the belt so as not to drop it.
2. Check that the heat radiation sheet is attached on the right side of the
motor (when seeing from the rear side of the Manipulator).
If the Manipulator is operated without the heat radiation sheet, the
motor generates heat and the error may occur.
If the heat radiation sheet has the protection film, remove the film.
Pass the pulley 1 of the Joint #1 motor unit to the Joint #1 timing belt
and loosely secure it to the base.

Make sure that the gear grooves of the timing belt are fit into those of
the pulley completely.
When securing the motor unit loosely, make sure that the motor unit
can be moved by hand and it does not tilt when being pulled.
If the unit is secured too loose or too tight, the belt will not have
proper tension.
