CHANGING SPEEDS AND ADJUSTING BELT TENSIONFig. 16
SPINDLE SPEEDSFive spindle speeds of 620, 1100, 1720, 2340 and 3100
RPM 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. Fig. 14, illustrates which step
of the motor and spindle pulley the belt must be placed
to obtain the five speeds available.
WARNING: MAKE SURE THE TOOL IS DIS-
CONNECTED FROM THE POWER SOURCE.
NOTE: A BELT POSITIONING SPEED CHART (E) FIG.
16, IS CONVENIENTLY LOCATED ON THE INSIDE
TOP COVER OF THE DRILL PRESS.
1. Lift up the belt and pulley guard (A) Fig. 16.
2. Release belt tension by loosening tension lock knob
(B) Fig. 16, and pivoting the motor toward the front of the
drill press.
3. While holding the motor toward the front of the drill
press head, position the belt (C) 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 (B) Fig. 17. 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 (C) can be
flexed about 1" out of line midway between the pulleys
using light finger pressure.
