2.4 Checking V-belt tension

When the machine has been moved the V-belt tension (which is

pre-set prior to despatch) must be checked.

When the tension is correct it should be possible to depress the middle

of the V-belt 1 by about 10 mm by pressing on it with a finger.

Correcting V-belt tension:

–

undo screw 2

–

swivel sewing drive 3 until the required V-belt tension is produced

–

tighten screw 2
