6.1 .......Feed Drive Belt - Access<br />
The feed drive belt (which takes the drive from the motor to the<br />
gearbox) is accessed by removing the six screws securing the belt<br />
cover and sliding the cover over the pulleys.<br />
The feed drive belt must be correctly tensioned as insufficient or<br />
excessive tension will cause vibration.<br />
Slacken the four nuts securing the motor bracket to the feed bed.<br />
Adjust the bracket as required to obtain the correct tension.<br />
When correctly tensioned the belt will deflect approximately 5mm<br />
(3/16”) when a force of 1.2Kg ( 2.6lb) is applied to the mid point of<br />
it’s run between the pulley’s.<br />
Note ........ Take care to keep the motor parallel to the gearbox.<br />
