are intended
as guides only. Always follow the manufacturer's speed
recommendations if provided with your drill bits, cutters,
or hole saws. Exceeding the recommended speeds may be
dangerous.
The speeds shown are intended to get you started. The
optimum speed will always depend on various factors,
including tool diameter, drilling pressure, material
hardness, material quality, and desired finish.

The belts in the head of the drill press must be
rearranged to change speeds. A chart under the belt
cover shows the belt positions needed to make the drill
press run at the desired speed.
To.change.speeds,.do.these.steps:
1.
UNPLUG THE DRILL PRESS!
2.
Loosen the belt tension lock knobs (shown in
Figure.
24
) on both sides of the headstock, so the motor is
free to move.
3.
Rotate the belt tension lever counterclockwise, as
shown in
Figure.25
, to take tension off the V-belts.
4.
Locate the desired speed on the speed chart under
the belt cover and move the V-belts to the desired
V-grooves on the motor, idler, and spindle pulleys.
.
For.Example:
As indicated on the drill press speed
chart on
Page.23
, a belt combination of A-2 creates
640 RPM.
Note:
Both belts may have to be removed before
certain speed changes can be made.
5.
Rotate the belt tension lever until the belts are
tight. Tighten both lock knobs.
6.
Close the cover before plugging in the machine.
