Always wear appropriate eye protection at all times.

Always remove jewelry, eliminate loose clothing, and confine long hair.

Only operate when all the guards are in place.

Always select properly sharpened drill bit, then tighten in chuck and remove key.

Clamp material-check for safety-and turn on power.

If a piece of work is caught in the drill, turn of the power. Do not try to stop it by hand!

Finally, select the speed carefully. The larger the drill, the slower the speed.
