OPERATIONS
INSTALLING A DRILL BIT
1. With the switch “OFF”, open the chuck jaws (1) using the chuck key (2). Turn
the chuck key counterclockwise to open the chuck jaws (1).
2. Insert the drill bit (3) into the chuck far enough to obtain maximum gripping by
the jaws, but not far enough to touch the spiral grooves (flutes) of the drill bit
when the jaws are tightened.
3. Make sure that the drill is centered in the chuck.
4. Turn the chuck key clockwise to tighten the jaws.
To avoid injury or accident by the chuck key ejecting
forcibly from the chuck when the power is turned ON, always recheck
and remove the chuck key before turning the power ON.
WARNING:
POSITIONING WORKPIECE (accessory fence supplied)
To prevent the workpiece or back-up material from being torn from your hands while drilling, you MUST position it against the LEFT side
of the column. Failure to do this could result in personal injury.
USING VISE
For small workpieces that cannot be clamped to the table, use a drill press vise. The vise must be clamped or bolted to the table.
CORRECT DRILLING SPEEDS
Use the recommended speed for the drill bit and workpiece. The drill bits that can be used is shown in the following picture:
The drill vise MUST be clamped or bolted to the table to avoid injury from a spinning workpiece, damaged
vise or bit parts.
WARNING:
Make sure to only adjust speeds with the crank handle while the machine is running, and adjust to the speed
chart below for the bit you are using.
