Check the belt tension every 400 hours of operation and adjust
if necessary.
Belt adjustment:

pushing it up to the desired position. Tighten and check the
tension. Alternatively, loosen the indicated screw one turn and
adjust using the eccentric washer. Pull gently.
Belt replacement:

itto slacken the belt.

Loosen the belt and replace it with anew one.
