15.0 Tensioning of the air motor drive belt.
There should be no need to alter the belt tensioning device providing it creates a deflection in the belt.
However if adjustments are required of the belt tensioner it would require the removal of the air chamber as-
sembly to gain access to its mounting screw through the top plate. Slacken the M6 CSK screw and rotate the
tensioner housing to pre load the arm to create the desired deflection (See photos of adjusted belt).
When the drive belt is removed it is an ideal opportunity to check the free rotation of all the idler and driven
pulleys. Also the free operation of the close arm assembly.
