SAFETY OPERATION MAINTENANCESETUP
Changing Drill Speed
See Functions on page 8 for illustrations.
1. WARNING! TO PREVENT SERIOUS
INJURY: Turn off and unplug the Drill
Press before changing drill speed.
2. Open the Pulley Cover.
3. Loosen the Belt Tension Lock Knobs
on both sides of the Head and turn the
Belt Tension Lever clockwise. This will bring
the Motor Pulley towards the Spindle Pulley,
removing all tension from the drive Belts.
4. Consult Figure D (or the chart inside the
Pulley Cover) and install the Belts on the
Pulleys in the positions that correspond
to the required spindle/drill speed.
5. When the Belts have been correctly positioned,
tighten them by turning the Belt Tension Lever
counterclockwise. The tension is correct when
the belts deflect by approximately 1/2″ at their
centers of run when using reasonable thumb
pressure. (See Figure A on page 8.) Lock this
position in with the two Belt Tension Lock Knobs.
Note: If a belt is too long to be properly
tensioned, it must be replaced.

Installing the Bit
CAUTION! Wear heavy-duty work gloves to provide
protection when inserting and removing drill bits. Drill
bits become very hot during use. Do not remove a drill
bit until it has cooled.
1. Use the supplied Chuck Key to open the
jaws of the drill enough to fit the drill bit.
2. Insert the drill bit approximately 1″ into
the jaws of the Chuck, ensuring that the
jaws do not touch the flutes of the bit.
3. Hand tighten the Chuck until the bit is held
securely in place. Confirm that the bit is
centered between the Chuck jaws.
4. Use the Chuck Key to tighten the Chuck.
• Insert the tip of the Chuck Key into a hole on the
side of the Chuck so that the teeth on the Key
engage the gear on the Chuck. Use the Key to
tighten the Chuck securely and remove the Key.
NOTICE: Use sharp bits. Dull, bent, or damaged
bits will cause stress on the drill and/or break.
