8. V-Belt Inspection, Adjustment and Replacement:
The MK-2000 PRO is designed with duel power transmission V-belts. In order to ensure the MK-2000 PRO
operates a peak efficiency, the two V-belts should be inspected monthly, and changed if they show signs of
damage and/or excessive wear.
NOTE: 1. When new belts are installed, they should be inspected and re-tensioned after the first forty-eight
(48) hours of operation.
