DeWalt DCH253-XE Instruction Manual page 11

Side Handle (Fig. 2)
WARNING: To reduce the risk of personal injury, ALWAYS operate the tool with
the side handle (A) properly installed. Failure to do so may result in the side handle
slipping during tool operation and subsequent loss of control. Hold tool with both
hands to maximize control.
The side handle (A) clamps to the front barrel (collar) and may be rotated 360° to
permit right-or left-hand use. The side handle can be tightened by rotating the black
plastic portion of the side handle clockwise. The side handle must be tightened
sufficiently to resist the twisting action of the tool if the accessory binds or stalls. Be
sure to grip the side handle at the far end to control the tool during a stall. To loosen
side handle, rotate counterclockwise.
Trigger Switch (Fig. 2)
To turn the tool on, squeeze the trigger switch (B). To turn the tool off, release the
trigger switch. Your tool is equipped with a brake. The chuck will stop as soon as the
trigger switch is fully released.
VARIABLE SPEED TRIGGER SWITCH
The variable speed trigger switch enables you to select the best speed for a particular
application. The farther you squeeze the trigger switch, the faster the tool will operate.
For maximum tool life, use variable speed only for starting holes or fasteners.
NOTE: Continuous use in variable speed range is not recommended. It may damage
the trigger switch and should be avoided.
Mode Selector (Fig. 3)
CAUTION: Never change the mode while the unit
is running.
For straight drilling, rotate the mode selector (D)
until the arrow points to the drill bit symbol (I). For
rotary hammer mode, align the arrow with the rotary
hammer symbol (J). For chipping mode, align arrow
with the chipping symbol (K).
NOTE: The mode selector (D) must be in drill,
hammer or chipping mode at all times. There are no
operable positions in between.
Forward/Reverse Control Button
(Fig. 2, 4)
A forward/reverse control button (C) determines the direction of bit rotation and also
serves as a lock-off button.
To select forward rotation, release the trigger switch (B) and depress the forward/
reverse control button on the right side of the tool.
To select reverse, depress the forward/reverse control button on the left side of the
tool.
The center position of the control button locks the tool in the off position. When
changing the position of the control button, be sure the trigger is released.
NOTE: The first time the tool is run after changing the direction of rotation, you may
hear a click on start up. This is normal and does not indicate a problem.

K
There is a worklight (F) located on the front of the
tool. The worklight is activated when the trigger
switch is depressed, and will automatically turn
D off 20 seconds after the trigger switch is
released. If the trigger switch remains depressed,
the worklight will remain on.
NOTE: The worklight is for lighting the immediate
J
work surface and is not intended to be used as

a flashlight.
