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.

of your tool, maintain the ventilation areas of your tool free from obstruction all the time.
4) HOW TO POSITION A DRILL BIT ON YOUR DRILL. Select the appropriate drill bit for the job (follow the guidelines
of the table below). First, make sure the drill is unplugged. Holding the rear section of the chuck, rotate the front
section until the jaws of the chuck are sufficiently open. Insert the drill bit in the jaws of the chuck. Hold the rear
section of the chuck while tightening the front. Turn the chuck key clockwise to tighten the jaws and securely
