Side Handle; Hammerdrill Operation - DeWalt DC900-XE Instruction Manual

while using the other hand to secure the tool.
Rotate the sleeve clockwise until sleeve can-
not be rotated any further, as demonstrated
in Figure 7. As the drill is being operated in
the forward position, the chuck will continu-
ally self-tighten the jaws of the chuck onto
the bit to maximize the bit gripping strength.
To release the accessory, repeat Step 2.
OPERATION
Installing and Removing the Battery
Pack (Fig. 8, 9)
NOTE: Make sure your battery pack is fully
charged.
CAUTION: Make certain the lock-off button (B), as shown in Figure 1, is engaged
to prevent switch actuation before removing or installing battery.
To install the battery pack into the tool handle, align the base of the tool with the
rails inside the tool's handle and slide the battery pack firmly into the handle until you
hear the lock snap into place (Fig. 8).
To remove the battery pack from the tool, press the release button (H) and firmly
pull the battery pack out of the tool handle. Insert it into the charger (Fig. 9) as
described in the charger section of this manual.

Side Handle

CAUTION: Always operate the tool with the side handle
properly assembled. Hold tool with both hands to maximize
control.
Side handle clamps to the front of the gear case as shown and
may be rotated 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.
If model is not equipped with side handle, grip drill with one hand on the handle and
one hand on the battery pack.
Drill Operation
1. Select the desired speed/torque range using the gear shifter to match the speed
and torque to the planned operation.
2. For WOOD, use twist bits, spade bits, power auger bits or hole saws. For METAL,
use high-speed steel twist drill bits or hole saws. Use a cutting lubricant when
drilling metals. The exceptions are cast iron and brass which should be drilled dry.
3. Always apply pressure in a straight line with the bit. Use enough pressure to keep
the drill bit biting, but do not push hard enough to stall the motor or deflect the bit.
4. Hold tool firmly with both hands to control the twisting action of the drill.
5. IF DRILL STALLS, it is usually because it is being overloaded. RELEASE
TRIGGER IMMEDIATELY, remove drill bit from work, and determine cause of
stalling. DO NOT CLICK TRIGGER OFF AND ON IN AN ATTEMPT TO START A
STALLED DRILL – THIS CAN DAMAGE THE DRILL.
6. Keep the motor running when pulling the bit back out of a drilled hole. This will
help prevent jamming.

Hammerdrill Operation

1. When drilling, use just enough force on the hammer to keep it from bouncing
excessively or "rising" off the bit. Too much force will cause slower drilling
speeds, overheating, and a lower drilling rate.
