DRILLING TIPS
CHUCK
KEY
If the hole is large, 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 also use a coolant.
As you increase the drill 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 your work.

When working with a tool outdoors, use an extension cord that is
designed for outside use. This is indicated by the letters "WA" on
the cord's jacket.
CAUTION: Keep the extension cord clear of the working
area. Position the cord so that it will not get caught on workpiece,
tools, or other obstructions while you are working with a power
tool.
Before using any extension cord, inspect it for loose or exposed
wires and cut or worn insulation.
**Used on 12 gauge - 20 amp circuit.
