DeWalt DCD932 Original Instructions Manual page 215

Variable Speed Switch (fi g. 1)
To turn the tool on, squeeze the trigger switch (a). To
turn the tool off, release the trigger switch. Your tool
is equipped with a brake. The tool holder will stop as
soon as the trigger switch is fully released.
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 switch and
should be avoided.
Side Handle (fi g. 1)
WARNING: To reduce the risk of
personal injury, ALWAYS operate
the tool with the side handle 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 (e) clamps to the front of the gear
case and may be rotated 360˚ to permit right- or
left-hand use. 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.
Forward/Reverse Control Button
(fi g. 1, 2)
WARNING: Always wait until the motor
has come to a complete standstill
before changing the direction of rotation.
A forward/reverse control button (b) determines the
direction of the tool and also serves as a lock off
button.
To select forward rotation, release the trigger switch
and depress the for ward/re verse control button on
the right side of the tool.
To select reverse, release the trigger switch and
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.
Worklight (fi g. 1)
DCH143, DCH253, DCH254
There is a worklight (d) located on the front of the
tool. The worklight will be activated when the trigger
switch is squeezed. The worklight is activated
when the trigger switch is depressed, and will
automatically turn 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
work surface and is not intended to be used as a
flashlight.
Selecting the Operating Mode (fi g. 1)
WARNING: Do not select the operating
mode when the tool is running.
Your tool is equipped with a separate mode
selector (c) to switch between rotary drilling, rotary
hammering and hammering only mode.
Rotary drilling: for screwdriving and for drilling
into steel, wood and plastics.
Rotary hammering: for concrete and
masonry drilling.
Hammering only: for light chipping.
For rotary drilling, rotate the mode selector (c)
until the arrow points to the drill bit symbol (i). For
rotary hammering mode, align the arrow with the
hammerdrilling symbol (j). For hammering only mode,
align arrow with the hammer symbol (k).
NOTE: The mode selector (c) must be in rotary
drilling, rotary hammering or hammering only mode
at all times. There are no operable positions in
between.
Active Vibration Control (fi g. 1)
The active vibration control neutralises rebound
vibration from the hammer mechanism. Lowering
hand and arm vibration, it allows more comfortable
use for longer periods of time and extends the life of
the unit.
