3) Adjusting the Drive Timing Belt
qRemove the Top Cover, the Right Side Panel and the Back Panel.
wTest the tension in the timing belt with a push-pull gauge at a point half way between the main
drive shaft pulley and the drive motor pulley. Adjust the belt tension by loosing the drive motor
and moving it up or down. Proper timing belt tension is in a range between loads of 75 and
125 grams with approximately 2 mm of slack in the belt. Refer to the diagram below.
eWind the rotor located on the back side of the motor mounting 3 times, then check the belt
tension once more to make sure that it is still in a range between loads of 75 and 125 grams
with approximately 2mm of slack in the belt.
rRepeat the same step of (3) eight times. If the tension falls in the above range eight times in a
row, the adjustment has been successfully completed. If even one test result falls that range,
the whole adjustment procedure must be repeated from the beginning.
