1, Open the belt cover (A), See Figure 12=1,
2 Loosen the tension lock knobs (B), one is on each
side,
3, Rotate the belt tension handle (C) forward, away
from the motor (D),
4, Position both belts (E) on selected pulleys accord=
ing to the drill speed diagram,
5, Rotate the belt tension handle back, towards the
motor to apply tension on the belts,
NOTE: The belt should be just tight enough to prevent
slipping, Excessive tension will reduce the life of the
belt, pulleys and bearings, Correct tension is obtained
when the belt can be flexed about 1" out of line midway
between the pulleys using light finger pressure,
6, Tighten both tension lock knobs,
