Operating Adjustments
To reduce the risk of injury:
• Turn switch “OFF” and remove plug from the power
source before making adjustments.
• Follow instructions carefully and wear eye protection to
avoid thrown parts due to spring release.
• Never operate drill press with pulley cover open
Install the belt (Fig. 14)
1. Open the pulley and belt cover (1).
2. Loosen the belt tension lock knobs (2) on both sides
of the drill press.
3. Slide the motor (3) as close to the drill press head as
possible.
4. Place a belt (4) on the motor pulley (5) and the
spindle pulley (6) in the proper position for the desired
speed (see Fig. 17).
5. Pull the motor away from the drill press head until the
belt is properly tensioned. Tighten the belt tension
lock knobs (2).
Note: The belt (4) should be tight enough to prevent
slippage. Correct tension is set if the belt flexes about
1/2" when thumb pressure is applied at the midpoint of
the belt between the pulleys.
Align the belt pulleys (Fig. 15)
1. Check the alignment of the pulleys with a straight edge
(1) (such as a ruler, level, or framing square) by laying
the straight edge across the top of the pulleys (2).
2. If the pulleys are NOT aligned, release belt tension by
loosening the belt tension lock knobs (3) on both
sides of the head.
3. Loosen the motor mount nuts (4) with an adjustable
wrench, and lower or raise the motor until the pulleys
are aligned.
4. Tighten the motor mount nuts (4) with an adjustable
wrench to maintain the position.
5. Lock the motor for the proper belt tension and tighten
the tension lock knobs (3).

Spindle speeds (Fig. 16)
This drill press offers 5 spindle speeds from 570 to 3050
RPM. The highest speed is obtained when the belt is
positioned on the largest motor pulley step and the
smallest spindle pulley stop.
