Operation
drilling
See Figures 20 - 21.
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.
