Belt Tension
Proper belt tension is necessary to maximize the effi ciency
of the Drill Bit. A simple adjustment has been provided to
allow the user to properly maintain belt tension. Remember
to check the belt tension often on the machine, especially
in the fi rst few hours of operation of a new machine. Before
checking belt tension and during belt tension adjustment
make certain your machine is DISCONNECTED from the AIR
SUPPLY and ELECTRICAL SUPPLY. Cycle the machine via
the foot switch several times to remove air from the system.
Without an air supply or electrical supply you can be certain
the motor will not accidentally rotate while you are performing
maintenance.
Step 1: Loosen the top 5/16” nut above the springs w/
wrench on the Motor Mounting Plate.
Step 2: Tighten the other 5/16” nut against the springs to
provide adequate belt tension for proper operation.
Step 3: Re-tighten the 5/16” nut against the other 5/16” nut
with wrench as a jam nut to maintain proper tension
on the belt.
