Installing and Removing the Battery Pack (Fig. F)
WARNING: Ensure the tool/appliance is in the off position
before inserting the battery pack.
nOTE: For best results, make sure your battery pack is
fully charged.
1. To install the battery pack
the battery pack with the rails inside the tool's handle and
slide it into the handle until the battery pack is firmly seated
in the tool and ensure that it does not disengage.
2. To remove the battery pack from the tool, press the
battery pack release button
pack out of the tool handle. Insert it into the charger.
Proper Hand Position (Fig. G)
WARNING: To reduce the risk of serious personal injury,
ALWAYS use proper hand position as shown.
WARNING: To reduce the risk of serious personal injury,
ALWAYS hold securely in anticipation of a sudden reaction.
Proper hand position requires one hand on the main
handle

Variable Speed Trigger and Forward/Reverse
Control Button (Fig. A)
The tool is turned on and off by pulling and releasing
the variable speed trigger
depressed, the higher the speed of the tool. Your tool is
equipped with a brake. The chuck will stop as soon as the
trigger switch is fully released.
A forward/reverse control button
rotational direction of the tool and also serves as a
lock‑off button.
• To select forward rotation (clockwise), release the trigger
and depress the forward/reverse control button on the right
side of the tool.
• To select reverse (counterclockwise), depress the
forward/reverse control button on the left side of the tool.
nOTE: 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: Continuous use in variable speed range is not
recommended. It may damage the switch and should
be avoided.
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 (Fig. A)
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.

Performing an Application (Fig. A)
WARNING: To reduce the risk of personal injury,
ALWAYS ensure workpiece is anchored or clamped firmly.
WARNING: Always wait until the motor has come to a
complete standstill before changing the direction of rotation.
Prior to Performing Work
• Set the speed selector
• Install the appropriate bit or accessory into the chuck.
Refer to accessory installation instructions in this manual.
WARNING:
• Do not use this tool to mix or pump easily combustible or
explosive fluids (benzine, alcohol, etc.).
• Do not mix or stir flammable liquids labeled accordingly.
Screwdriving
Your tool has a clutch with adjustable torque for driving
and removing a wide array of fastener shapes and sizes. The
numbers 1–15 on the mode selection collar
set a torque range for screwdriving. The higher the number
on the collar, the higher the torque and the larger the
fastener which can be driven.
1. Turn the mode selection collar to the desired position.
Refer to Mode Selection.
2. Pull the trigger switch applying pressure in a straight line
with the bit until the fastener is seated at the desired depth
in the workpiece.
Recommendations for screwdriving
1
.
• Start with lower torque settings, then advance to
higher torque settings to avoid damage to the workpiece
or fastener.
• Make some practice runs in scrap or on unseen areas
of the workpiece to determine the proper position of the
mode selection collar.
Drilling
iMPORTAnT: For MASONRY, such as brick, cement, cinder
block, etc., use carbide‑tipped masonry bits.
1. Turn the mode selection collar
Refer to Mode Selection.
2. Place drill bit in contact with the workpiece.
nOTE: Use sharp drill bit only.
3. Pull the trigger switch applying pressure in a straight line
with the bit until it reaches the desired depth.
WARNING: Drill may stall if overloaded causing a sudden
twist. Always expect the stall. Grip the drill firmly to control the
twisting action and avoid injury.
4. Keep the motor running when pulling the bit back out of
a drilled hole to prevent jamming.
Recommendations for Drilling
• When drilling, always apply pressure in a straight line with
the bit, but do not push hard enough to stall the motor or
deflect the bit.
• iF ThE DRill sTAlls:
‑ RElEAsE TRiggER sWiTCh iMMEDiATElY, remove drill

‑ To minimize stalling or breaking through the material,
reduce pressure on drill and ease the bit through the last
fractional part of the hole.
