VARIABLE SPEED TRIGGER
The variable speed trigger switch (A) permits speed control. The
farther the trigger switch is depressed, the higher the speed of the drill.
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 masonry for maximum efficiency.
REVERSING LEVER
The reversing lever is used to reverse the rotary hammer for backing
out screws or jammed bits. It is located above the trigger, shown in
Figure 2.
D25101, D25103
To reverse the rotary hammer, turn it OFF and align the reversing lever
(C) with the yellow arrow pointing backward (viewed when holding drill
in operating position).
To position the lever for forward operation, turn the rotary hammer OFF
and align the reversing lever with the yellow arrow pointing forward
(viewed when holding drill in operating position).
D25201, D25203, D25303, D25304
To reverse the rotary hammer, turn it OFF and push the reversing lever
in so the yellow arrow pointing backwards shows.
To position the lever for forward operation, turn the rotary hammer
OFF and push the reversing lever in so the yellow arrow pointing
forward shows.
CAUTION: When reversing to clear jammed bits, be ready for
strong reactive torque.

LOCK ON BUTTON (D25101, D25103 ONLY)
To lock the trigger switch in the ON position for continuous operation,
depress the trigger switch and slide up the lock on button (B). The
tool will continue to run.
To turn the tool OFF from a locked ON condition, squeeze once then
release the trigger. Before using the tool each time, be sure that the
lock on 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 lock
on button is for use only when the rotary hammer is mounted in a drill
press stand or otherwise held stationary.
CAUTION: Be sure to release the locking mechanism before
disconnecting the plug from the power supply. Failure to do so will
cause the rotary hammer to start immediately the next time it is
plugged in. Damage or injury could result.
