PULLEY ALIGNMENT AND SPEED ADJUSTMENT

Checking pulley alignment
Warning: To reduce the risk of injury due to accidental starting
always turn drill press off and remove safety key before making belt
adjustments.
The pulleys and motor are assembled at the factory and should
require no further adjustment. If the pulleys or motor are removed for
service, follow the pulley alignment instructions below.
1. Place a straightedge such as a piece of wood, metal, or framing
square across the top of the pulleys.
2. The top of all three pulleys should touch the straightedge.
3. If not, a) Loosen motor mount nuts. b)Move motor until the pulleys
are in line. c) Retighten the motor mount nuts.
NOTE: To avoid rattles or other noises, motor frame must not touch
lower belt guard.
Speed adjustment
1. Release belt tension lock handles located on each side of the drill
press by turning them counterclockwise.
2. Loosen belt tension by turning the belt tension handle clockwise.
3. Use the speed chart inside the belt guard to choose the speed for the
drilling operation. Install belts in the correct position for the
desired speed. The longer of the two belts is always positioned
between the spindle pulley and the idler pulley.
NOTE: Refer to inside belt guard for recommended drilling speeds.

TENSIONING BELT

1. Apply tension to the belt by turning belt tension handle
counterclockwise until belt deflects approximately 1/2" by thumb
pressure at its center.
2. Tighten belt tension lock handles. NOTE: Over tensioning belt may
cause the motor not to start or damage bearings.
3. If belt slips while drilling, reajust belt tension.
