general rule, use low speeds for large diameter drill bits and high speeds for smaller diameter drill bits.
OPERATIONS
1) AS A GENERAL RULE. For large size drill bits use low speeds and for smaller drill bits use high speeds. On
variable speed drills, the more the trigger is pressed the faster the speed.
2) SET THE SPEED OF YOUR DRILL. Set the forward/reverse switch to the desired direction of rotation. Never
change the setting of the hammer switch, or the forward/reverse when your drill is in operation.
3) MAINTAIN VENTS CLEAR OF OBSTRUCTION. In order to maintain your tool from over heating and extend the life
of your tool, maintain the ventilation areas of your tool free from obstruction all the time.

support. Always drill at a 90º angle and place enough pressure on the drill for the drill to perforate the surface
you are drilling. Never use excessive force when using your drill.
6) ACCESSORIES: Various accessories can fit your drill, allowing you to diversify its use.
7) SANDING / POLISHING: Position the disc as shown in the figure below. Place the rubber support in the chuck
and turn the chuck key clockwise to tighten the jaws to securely fasten the disc. To set the polishing feature
follow the example using the rubber disc and the spindle.
