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 notch inside the tool’s
handle with the battery pack and slide the battery pack firmly into the handle until you
hear the lock snap into place as shown in Figure 8.
To remove the battery pack from the tool , press the release buttons (G) 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
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.
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.
2. Drill straight, keeping the bit at a right angle to the work. Do not exert side
pressure on the bit when drilling as this will cause clogging of the bit flutes and a
slower drilling speed.
3. When drilling deep holes, if the hammer speed starts to drop off, pull the bit
partially out of the hole with the tool still running to help clear debris from the
hole.
4. For MASONRY, use carbide-tipped bits or masonry bits. A smooth, even flow of
dust indicates the proper drilling rate.
Screwdriver Operation
Select the desired speed/torque range using the three-speed gear shift lever on
the top of tool to match the speed and torque to the planned operation. Insert the
desired fastener accessory into the chuck as you would any drill bit. Set the torque
