SPINDLE SPEEDS
Sixteen spindle speeds of: 240, 320, 360, 470,
540, 580, 860, 880, 1130, 1270, 1350, 1560,
1990, 2020, 2480 and 3150 are available with
your drill. 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. 13.

BELT TENSION
1. Disconnect the drill press from the power
supply.
2. Remove the pulley cover locking screw
Fig. 14 and open the pulley cover.
3. Release the belt tension by releasing the
tension lock knobs
to release tension on the motor.
4. Position the two belts
steps of the motor, centre and spindle pulleys,
as shown in Fig.15.
5. After the belt is positioned on the desired
steps of the motor and spindle pulleys, turn
handle
to retension the motor, tighten lock
knobs

tightened just enough to prevent it from
slipping. Excessive tension will reduce the life
of the belts pulleys and bearings. Correct
tension is obtained when the belts can be
flexed approximately 25mm out of line
midway between the pulleys using light finger
pressure.
