SPINDLE SPEEDS
Five spindle speeds of 550-2500r.p.m. are
available with your drill press. The highest speed
is obtained when the belt is on the largest step of
the motor pulley and the smallest step of the
spindle pulley as shown in Fig.14.
3. Loosen locking knob Fig.16. While holding
the motor towards the front of the drill press
head, position the belt on the desired steps
of the motor and spindle pulleys, as shown in
Fig.16.

4. After the belt is positioned on the desired
steps of the motor and spindle pulleys, pivot
motor away from the drill press head until the
belt is properly tensioned and tighten tension
lock knob Fig.16. 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. Close pulley cover and secure
using locking screw Fig.15.
