Variable Speed
The variable speed trigger switch permits speed control. The
farther the trigger switch is depressed, the higher the speed
of thehammerdrill.
NOTE: Use lower speeds for starting holes without a
centerpunch, drilling in metal, plastics or ceramics, or
driving screws. Higher speeds are better for drilling in
wood and composition board and for using abrasive and
polishingaccessories.
