Changing Speeds - Grizzly G7945 Owner's Manual

Changing Speeds

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.

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.
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.
