U1 belt

Installation

(1) Keeping the U1 belt on the large pulley of

the Joint #4 intermediate shaft unit, set the

U2 belt in the Arm #2 on the small pulley

and put them on the Arm #2 upper surface.

Make sure the gear grooves of the belts are

fit into those of the pulleys completely.

(2) Loosely secure the Joint #4 intermediate shaft unit.

Make sure the motor unit can be moved by hand, and it will not tilt when pulled.

If the unit is secured too loose or too tight, the belt will not have the proper tension.

(3) Apply the proper tension to the U2 belt,

and then secure the Joint #4
intermediate shaft unit.

Pass a suitable cord or string around the
Joint #4 intermediate shaft unit near its
mounting plate.

Then, pull the cord using a force gauge

or similar tool to apply the specified

tension shown in the figure on the right.

U1 belt tension:

LS3

= 69 N (7.0

0.5 kgf)

LS6 (a) = 69 N (7.0

0.5 kgf)

LS6 (b) = 102 N (10.4

(4) Loosely secure the Joint #4 motor unit to

Arm #2.

Make sure the motor unit can be moved by

hand, and it will not tilt when pulled.

If the unit is secured too loose or too tight,

the belt will not have the proper tension.
