SPEED/BELT CHANGING

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.

CHANGING SPEEDS AND ADJUSTING BELT

TENSION

1. Disconnect the drill press from the power

supply.

2. Remove the pulley cover locking screw

Fig.15. and open the pulley cover.

3. Loosen locking knob

the motor towards the front of the drill press

head, position the belt

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
