Using the vise provided (or similar clamping devices), 
secure the workpiece to the table. To protect the top 
surface of the workpiece, use a piece of scrap wood 
between the vise and the workpiece.
Select the proper drill bit based on the hole size desired. 
For large holes, drill a pilot hole first, using a smaller 
diameter bit.
Unlock the spindle lock lever and the lock knob. Using 
the feed handles, set the spindle at the desired depth and 
retighten both the lock lever and lock knob securely.
Turning the table adjustment handle, set the table to 
desired height.
NOTE: Make sure the table is free of all loose objects and 
the bit is not in contact with the workpiece.
Plug the electrical cord into power supply and turn the 
switch 
ON. Make sure spindle rotates freely.
With the motor running, change the spindle speed with 
the variable speed lever.
NOTE: The digital display on the front of the drill press 
will give you the exact spindle speed. Use the chart below 
to determine speed for the material and drill size.

Slowly lower drill bit into workpiece. Do not force the bit; 
let the drill press do the work.
Once the hole is completed, allow the spindle to return to 
its normal position. This will automatically raise the chuck 
and bit.
DRILLING TIPS
If a large hole is needed, it’s a good idea to drill a smaller 
pilot hole before drilling the final one. Your hole will be 
more accurately positioned, rounder, and the bits will last 
longer.
If the hole is deeper than it is wide, back off occasionally 
to clear the chips. 
When drilling metal, lubricate the bit with oil to improve 
drilling action and increase bit life.
As you increase the bit size, you may need to reduce the 
spindle speed.
If drilling a through hole, make sure that the bit will not 
drill into the table after moving through the workpiece.
