G7945/G7946 Radial Drill Press

-25-

Never operate drill press with pulley cover in

the open position. Your hand may become

trapped in the belt and serious personal

injury will occur.

Figure 21. Loosening lock knob (both sides).

The belt in the head of the drill press must be

rearranged to change speeds. A chart under the

pulley cover shows the belt positions needed to

make the drill press run at the desired speed.

To change speeds

1. UNPLUG THE DRILL PRESS!

2. Loosen the belt tension lock knobs (shown in

Figure 21) on both sides of the headstock,

so the motor is free to move.

Changing Speeds

3. Locate the desired speed on the speed chart

under the pulley cover, and move the V-belt

to the desired V-grooves on the motor and

spindle pulleys.

4. Pivot the motor toward the back of the head-

stock and tighten the lock knobs once the

desired V-belt tension is achieved.

5. Close the cover before plugging in the

machine.
