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.
