CAUTION
If the Timing Belt is placed on the flange, correct tension will not be obtained during belt
tension adjustment.
Temporarily secure the J3 Motor unit.
POINT
The standard for temporary fastening is where the Motor Unit can be moved by hand and
will not tilt when pulled. If this is either too loose or too tight, it will not provide the proper
tension to the belt.
Adjust the belt tension.
3.1 Adjusting the Timing Belt Tension
Install the Arm2 side cover.
After assembly, perform calibration of Joint #3.
3.2 Calibration
Set the belt so that it is level
with respect to the pulley
without it being placed on the
flange.
