Changing the speed of the drill press

The speed of the drill press is determined by the size of the pulley steps that the belt is attached to. Using a smaller pulley step on the front pulley means a faster drill speed; using a larger pulley step on the front pulley means a slower drill speed. The below table indicates the speed of the drill in the various belt positions.

1.Remove the plug from the mains socket.

2.Loosen and remove the pulley cover knob (5) and lift the pulley cover (4).

3.Loosen the belt tension knob (11) and push the motor housing towards the front of the drill press to make belt changes easier.

4.To select a faster drill speed, move the belt up to a smaller step on the front pulley. Then move it up to the equivalent step on the rear pulley. Rotating the pulleys and “rolling” the belt onto the larger pulley will make this easier.

5.To select a slower drill speed, move the belt down to a smaller step on the rear pulley. Then move it down to a larger step on the front pulley. Rotating the pulleys and “rolling” the belt onto the larger pulley will make this easier.

Note. The belt should always be on the same relative step on the front and rear pulleys, for example if it is on the top step of the front pulley then it should also be on the top step of the rear pulley.

6.Tighten the belt tension knob (11) to secure the motor in position

7.Rotate the pulley by hand to ensure everything is aligned and correct.

8.Lower the pulley cover and replace the pulley cover knob. Tighten the pulley cover knob to secure the pulley cover in the closed position.

Note. The drill press features a micro switch that disables the on/off switch if the cover is not in the fully closed position.

Turning on and off

1.Insert the switch disabling insert and ensure the switch

(3)is in the OFF position.

2.Ensure the pulley cover is in the fully closed position.

3.Lift the switch to the ON position (I) to turn on and operate the drill press.

4.Push the switch down to the OFF position (0) to turn off the drill press.
