Variable Speed - DeWalt DW508S Manual De Instrucciones

Switch (Fig. 1)
WARNING: Be sure to release the locking mechanism before
disconnecting the plug from the power supply. Failure to do so will
cause the hammerdrill to start immediately the next time it is plugged
in. Damage or personal injury could result.
To start hammerdrill, depress the trigger switch (A). To stop hammerdrill,
release the trigger switch.
To lock the trigger switch in the ON position for continuous operation,
depress the trigger switch and push up the locking button (B). The
tool will continue to run. To turn the tool OFF, from a locked-on
condition, squeeze and release the trigger once. Before using the
tool (each time), be sure that the locking button release mechanism
is working freely.
DO NOT lock the switch on when drilling by hand so that you can
instantly release the trigger switch if the bit binds in the hole. The
locking button is for use ONLY when the hammerdrill is mounted in a
drill press stand or other wise held stationary.

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 center punch,
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.
REVERSING LEVER
The reversing lever (C) is used to reverse the hammerdrill for backing
out screws or jammed bits. It is located above the trigger, shown. To
reverse the hammerdrill, turn it OFF and push the reversing lever to
the left (when viewed from the chuck end). To position the lever for
forward operation, turn the hammerdrill OFF and push the lever to
the right.
Hammer/Drill Selector (Fig. 2)
To switch the tool from the drilling mode to the hammering mode (or
vice-versa) rotate the dial (D) on the applicable symbol. For straight
drilling, align the drill bit symbol toward the chuck. For hammering,
align the hammer symbol with the lever, as shown in the figure.
NOTE: The selector must be in either drill, or hammer/drill mode at all
times. There are no operable positions between the two.
