Drive Belt Tension
Remove the motor/drive access panel, if not done so already.
Check the tension of the belt by pushing the belt, there should
be a deflection of between (12-20mm). If there is considerable
movement in the belt, adjust the motor's threaded pivot stop.
Sprockets
To adjust the threaded stop first loosen the motor's pivot bolt
(A) on the motor's base plate then adjust the threaded stop
nuts (B and C) until the drive belt is under tension. Nip up the
pivot bolt (A), see fig 36-37.
