From  the  fully  disengaged  position,  gently  turn  the
engagement  handle  clockwise  until  you  feel  it  start  to  resist.
From  this  position,  turn  the  engagement  handle  one  full
revolution clockwise. This is the recommended tension for the
belt drive when in the fully engaged position.

Using two 24 mm spanners, screw the two M16 adjustment
nuts downwards until they touch the adjustment block. Then
turn the top nut clockwise and the bottom nut anti clockwise
simultaneously to lock the nuts in place.

Belt replacement

If the belts in your chipper look similar to any of the following images or are clearly broken, then they need to be replaced.

If a belt change is necessary, follow these steps:

Using a 6 mm Allen key, unbolt and remove the pulley
guard (3 x M8 cap screws).
