DRILLING METAL
To reduce the risk of injury, tighten all lock handles before starting the machine. Loss of control of the
workpiece can cause serious injury.
Use clamps to hold metal workpieces. Never hold the workpiece in your bare hand. The drill bit can seize the work at
any time, especially when breaking through the workpiece and cause damage to the machine or injury to you. The drill
bit will break if the workpiece strikes the column.
Clamp the workpiece firmly. Any tilting, twisting, or shifting results not only in a rough hole, but also in bit breakage.
For flat work, lay the workpiece on a wooden base and clamp it firmly against the table to prevent it from turning. If the
workpiece is of irregular shape and cannot lay flat on the table, securely block or clamp it.

MAINTENANCE
To reduce the risk of injury, turn unit off and disconnect it from power source before installing and
removing accessories, before adjusting or when making repairs. An accidental start-up can cause injury.
KEEP MACHINE CLEAN
Periodically blow out all air passages with dry compressed air. All plastic parts should be cleaned with a soft damp cloth.
NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the material.
Wear certified safety equipment for eye, hearing and respiratory protection while using compressed air
FAILURE TO START
Should your machine fail to start, check to make sure the prongs on the cord plug are making good contact in the outlet.
Also, check for blown fuses or open circuit breakers in the line.
LUBRICATION & RUST PROTECTION
Apply household floor paste wax to the machine table, extension table or other work surface weekly. Or use a
commercially available protective product designed for this purpose. Follow the manufacturer’s instructions for use and
safety.
To clean cast iron tables of rust, you will need the following materials: a medium sized scouring pad, a can of spray
lubricant and a can of degreaser. Apply the spray lubricant and polish the table surface with the scouring pad. Degrease
the table, then apply the protective product as described above.
INSPECT THE BELTS
Occassionally inspect the belts for wear and replace as
needed.
INSPECT THE BOLTS
Occassionally remove the knuckle clamp bolt (K) Fig. 49
and table clamping bolt (T) Fig. 50 and clean off all dust
and other contamination. Also, be sure to clean any dust
or contamination from the hole using a small brush (like
an old toothbrush).
