Always remove battery pack before
WARNING
changing or removing accessories.
To insert the battery, slide the pack into the body
of the tool. Make sure it latches securely into place.
Only use accessories specifically
WARNING
recommended for this tool. Others
may be hazardous.
Installing Bits
NOTE: Only use accessories with SDS or SDS Plus
shanks.
Be sure that the shank of the bit is clean. Dirt particles
may cause the bit to line up improperly. Do not use
bits larger than the maximum recommended capacity
of the drill because gear damage or motor overload-
ing may result. For best performance, be sure that
the bit is properly sharpened and the shank is lightly
greased before use.
1. Insert the bit into the nose of the tool.
2. Rotate bit slowly until it aligns with the locking
mechanism.
3. Push bit into tool until it locks.
4. Check that the bit is locked properly; it should be
possible to pull the bit back and forth slightly (about
1/4").
5. To remove bits, pull bit holder release collar toward
the rear of tool and remove bit.
NOTE: Use caution when handling hot bits.
OPERATION
Always remove battery pack before
WARNING
changing or removing accesso-
ries. Only use accessories specifically recom-
mended for this tool. Others may be hazardous.
To reduce the risk of injury, keep hands away
from the bit and all moving parts. Always wear
safety goggles or glasses with side shields.
To reduce the risk of injury, wear a dust mask or
use an OSHA compliant dust extraction solution
when working in dusty situations.
Fuel Gauge
To determine the amount of charge left in the bat-
tery, pull the trigger. The Fuel Gauge will light up for
2-3 seconds.
To signal the end of charge, 1 light on the fuel gauge
will flash for 2-3 seconds.
Selecting Action
Always allow the motor to come to a complete stop
before changing the mode selection to avoid dam-
age to the tool.
1. For drilling, turn the mode selector
so the arrow points to the twist
drill symbol.
2. For rotary hammering, turn the
mode selector so the arrow
points to the hammer and twist
drill symbol.
NOTE: To engage the hammering mechanism,
maintain pressure on the bit. When pressure on the
bit is released, the hammering action will stop.
Using the Control Switch
The control switch may be set to three positions:
forward, reverse and lock. Always allow the motor
to come to a complete stop before using the control
switch to avoid damage to the tool.
For forward (clockwise) rotation, push in the control
switch from the right side of the tool. Check the direc-
tion of rotation before use.
For reverse (counterclockwise) rotation, push in the
control switch from the left side of the tool. Check
direction of rotation before use.
To lock the trigger, push the control switch to the
center position. The trigger will not work while the
control switch is in the center locked position. Always
lock the trigger or remove the battery pack before
performing maintenance, changing accessories,
storing the tool and any time the tool is not in use.
Starting, Stopping and Controlling Speed
1. To start the tool, grasp the handle firmly and pull
the trigger.
NOTE: An LED is turned on when the trigger is
pulled.
2. To vary the speed, increase or decrease the pres-
sure on the trigger. The further the trigger is pulled,
the greater the speed.
3. To stop the tool, release the trigger. Make sure
the tool comes to a complete stop before laying
the tool down.
Position the tool, grasp the handle firmly and pull
the trigger. Always hold the tool securely to maintain
control. This tool has been designed to achieve top
performance with only moderate pressure. Let the
tool do the work.
If the speed begins to drop off when drilling large or
deep holes, pull the bit partially out of the hole while
the tool is running to help clear dust. Do not use water
to settle the dust since it will clog the bit flutes and
tend to make the bit bind in the hole. If the bit should
bind, stop the tool, free the bit and begin again.
APPLICATIONS
To reduce the risk of electric shock,
WARNING
check work area for hidden pipes
and wires before drilling or driving screws.
Selecting Bits
When selecting a bit, use the right type for your job.
For best performance, always use sharp bits.
1. Before drilling, be sure the workpiece is clamped
securely. Use backing material to prevent damage
to the workpiece during breakthrough.
2. When starting a hole, place the drill bit on the work
surface and apply firm pressure. Begin drilling at
a slow speed, gradually increasing the speed as
you drill.
3. Always apply pressure in line with the bit. Use
enough pressure to keep the drill biting, but do
not push hard enough to stall the motor.
4. Reduce pressure and ease the bit through the last
part of the hole. While the tool is still running, pull
the bit out of the hole to prevent jamming.
Drilling in Wood, Composition Materials
(Use chuck adapter kit Cat. No. 48-66-1370)
When drilling in wood, composition materials and
plastic, start the drill slowly, gradually increasing
speed as you drill. When drilling into wood, use
wood augers or twist drill bits. Always use sharp
bits. When using twist drill bits, pull the bit out of the
hole frequently to clear chips from the bit flutes. To
reduce the chance of splintering, back work with a
piece of scrap wood. Use low speeds for plastics with
a low melting point.
