SAFETY INSTRUCTIONS
GENRAL SAFETY RULES
WARNING: Read all safety warnings and instructions. Failure to follow the
warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term power tool in the warnings refers to your mains-operated (corded)
power tool or battery-operated (cordless) power tool.
1) WORK AREA SAFETY
Keep work area clean and well lit. Cluttered or dark areas invite
accidents.
Do not operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
2) ELECTRICAL SAFETY
Power tool plugs must match the outlet. Never modify the plug in any
way. Do not use any adapter plugs with earthed (grounded) power
tools. Unmodified plugs and matching outlets will reduce risk of electric
shock.
Avoid body contact with earthed or grounded surface, such as pipes,
radiators, ranges and refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord for carrying, pulling or
unplugging the power tool. Keep the cord away from heat, oil, sharp
edges or moving parts. Damaged or entangled cords increase the risk of
electric shock.
When operating a power tool outdoors, use an extension cord suitable
for outdoor use. Use of a cord suitable for outdoor use reduces the risk of
electric shock.
If operating a power tool in a damp location is unavoidable, use a
residual current device (RCD) protected supply. Use of an RCD reduces
the risk of electric shock.

6
3) PERSONAL SAFETY
Stay alert, watch what you are doing and use common sense when
operating a power tool. Do not use the tool while tired or under the
influence of drugs, alcohol, or medication. A moment of inattention while
operating power tools may result in serious personal injury.
Use personal protective equipment. Always wear eye protection.
Protective equipment such as dust mask, non-skid safety shoes, hard hat,
or hearing protection used for appropriate conditions will reduce personal
injuries.
Prevent unintentional starting. Ensure that the switch is in the OFF
position before connecting it to a power source and/or battery pack,
picking up or carrying the tool. Carrying power tools with your finger
on the switch or energizing power tools that have the switch on invites
accidents.
Remove any adjusting key or wrench before turning the power tool
on. A wrench or a key left attached to a rotating part of the power tool may
result in personal injury.
Do not overreach. Keep proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewelry. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewelry or
long hair can be caught in moving parts.
If devices are provided for the connection of dust extraction and
collection facilities, ensure that these are connected and properly
used. Use of these devices can reduce dust-related hazards.
4) POWER TOOL USE AND CARE
Do not force the power tool. Use the correct power tool for your
application. The correct power tool will do the job better and more safely at
the rate for which it was designed.
Do not use the power tool if the switch does not turn it on and off. Any
power tool that cannot be controlled with the switch is dangerous and must
be repaired.
Disconnect the plug from the power source and/or the battery pack
from the power tool before making any adjustments, changing
accessories, or storing power tools. Such preventive safety measures
reduce the risk of starting the power tool accidentally.
Store idle power tools out of the reach of children and do not allow
persons unfamiliar with the power tool or these instructions to operate
the power tool. Power tools are dangerous in the hands of untrained users.

7
Maintain power tools. Check for misalignment or binding of moving
parts, breakage of parts and any other condition that may affect the
power tool’s operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly maintained power tools.
Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
Use the power tool, accessories, tool bits. etc., in accordance with
these instructions, taking into account the working conditions and the
work to be performed. Use of the power tool for operations different from
those intended could result in a hazardous situation.
5) BATTERY TOOL USE AND CARE
Recharge only with the charger specified by the manufacturer. A
charger that is suitable for one type of battery pack may create a risk of fire
when used with another battery pack.
Use power tools only with specifically designated battery packs. Use of
any other battery packs may create a risk of injury and fire.
When battery pack is not in use, keep it away from other metal objects,
such as paper clips, coins, keys, nails, screws or other small metal
objects that can make a connection from one terminal to another.
Shorting the battery terminals together may cause burns or a fire.
Under abusive conditions, liquid may be ejected from the battery;
avoid contact. If contact accidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help. Liquid ejected from the
battery may cause irritation or burns.
6) SERVICE
Have your power tool serviced by a qualified repair person using only
identical replacement parts. This will ensure that the safety of the power
tool is maintained.
SPECIFIC SAFETY RULES FOR CORDLESS HAMMER DRILL
Use this tool only with the batteries and charger listed below:
Battery pack Charger
252-0900
252-0908 252-0912
Hold power tools by their insulated gripping surfaces when performing
an operation where the cutting tool may contact hidden wiring or its
own cord. Contact with a “live” wire will also make exposed metal parts of
the tool “live” and shock the operator.

8
Use protective gloves when removing the bit from the tool, or first allow
the bit to cool down. The bit may be hot after prolonged use.
Keep your hands away from the motor-housing vents. Hot gas comes
from the vents during operation.
Do not operate the tool at full-load for more than 30 seconds, as this
can cause the motor to become too hot, which may damage the motor.
Release the trigger immediately when the screws are tightened to avoid
breaking the screw.
For best results, your battery tool should be charged in a location where the
temperature is more that 41oF (5oC) but less that 122oF (50oC). Do not store
outside or in vehicles.

OPERATION
BATTERY PROTECTION
To protect the battery from damage and prolong its life, the battery pack’s
circuitry will turn off the battery pack if it becomes overloaded or if the
temperature becomes too high during use. This may happen in extremely high
torque, binding and stalling situations. The battery pack will begin normal
operation when it cools down.
NOTICE: A significantly reduced run time after fully charging the battery pack
indicates that the batteries are near the end of their usable life and must be
replaced.
COLD WEATHER OPERATION
When the battery pack is very cold, it may “pulse” for the first minute of use to
warm itself. Put the battery pack on a tool and use the tool in a light application.
After about a minute, the battery pack will have warmed itself and will operate
normally.
WHEN TO CHARGE THE BATTERY PACK
The Lithium-Ion battery can be charged at any time and will not develop a
“memory” when charged after only a partial discharge. It is not necessary to
run down the battery pack charge before recharging. Remove the battery pack
from the tool when convenient for you and your job.
You can “top-off” your battery pack’s charge before starting a big job or long
period of use.
Due to Lithium-Ion’s fade-free properties, the only time it is necessary to
charge the Lithium- Ion battery pack is when the pack has reached the end
of its charge. To signal the end of charge, power to the tool will drop quickly.
Charge the battery pack as needed.

13

KEYLESS CHUCK (Fig. 6)
The hammer drill has a keyless chuck to tighten or release drill bits in the chuck
jaws. The arrows on the chuck indicate which direction to rotate the chuck
body in order to GRIP (tighten) or OPEN
(release) the chuck jaws on the drill bit.
WARNING: Do not hold the chuck body
with one hand and use the power of the
drill to tighten the chuck jaws on the drill
bit. The chuck body could slip in your hand,
or your hand could slip and come in con-
tact with the rotating bit. This could cause
an accident resulting in serious personal
injury.
TWO-SPEED GEAR BOX (Fig. 7)
The drill has a two-speed gear box designed for drilling or driving at LO or HI
speeds. A slide switch is located on the top of the drill to select either LO or HI
speed.
When using the drill in the LO speed
range, the speed will decrease and the
drill will have more power and torque.
When using drill in the HI speed range,
the speed will increase and the drill
will have less power and torque. Use
LO speed for high power and torque
applications and HI speed for fast drilling
or driving applications.
Use LO speed for starting holes without
a center punch, drilling metals or plastic, drilling ceramics, or in applications
requiring a higher torque (see below).
HI speed is better for drilling wood and wood composites and for using abrasive
and polishing accessories.
CAUTION! Never change gears while the tool is running. Failure to obey this
caution could result in serious damage to the drill.
NOTICE: Avoid running the drill at LO speed for extended periods of time.
Running at LO speed under constant usage may cause the drill to become
overheated. If this occurs, cool the drill by running it without a load at HI speed.

NOTICE: The torque adjustment ring may be set on any number.
Hammer drilling
Rotate the mode selection ring so the hammer symbol is aligned with the arrow.
ADJUSTABLE TORQUE CLUTCH (Fig. 9)
The torque clutch can be adjusted to 24
different settings. The higher the torque
setting, the more force the drill produces
to turn an object in either LO or HI rotation
speed.
When using the drill for different driving
applications, it is necessary to increase
or decrease the torque in order to help
prevent the possibility of damaging screw
heads, threads, workpiece, etc.
Adjust the torque by rotating the torque-adjustment ring.
The proper setting depends on the job and the type of bit, fastener, and material
you will be using. In general, use greater torque for larger screws, but if the
torque is too high, the screws may be damaged or broken.
For delicate operations, such as removing a partially stripped screw, use a
low torque setting. For operations such as drilling into hardwood, use a higher
torque setting.

to close the chuck jaws. Do not use a wrench to tighten or loosen the chuck
jaws.
3. Remove the drill bit.
USING THE AUXILIARY HANDLE ASSEMBLY
WARNING: To reduce the risk of injury, always use the auxiliary handle
when operating and hold tool with both hands to maximize control.
The auxiliary handle must be tightened sufficiently to resist the twisting
action of the tool if the bit binds or stalls. Be sure to grip the side handle at
the far end to control the tool during a stall.
The auxiliary handle can be attached to either side for left- or right-hand use.
GENERAL DRILLING (Fig. 12)
1. Check the direction of rotation
selector for the correct setting
(forward or reverse).
2. Secure the material to be drilled in a
vise or with clamps to keep it from
turning as the drill bit rotates.
3. Hold the drill firmly and place the bit
at the point to be drilled.
4. Depress the trigger switch to start the drill.
5. Move the drill bit to contact the workpiece, applying only enough pressure
to keep the bit cutting. Do not force the drill or apply side pressure to
elongate a hole. Let the tool do the work.
6. When drilling hard, smooth surfaces, use a center punch to mark the
desired location of the hole. This will prevent the drill bit from slipping off-
center as the hole is started.
7. When drilling metals, use light oil on the drill bit to keep it from overheating.
The oil will prolong the life of the bit and increase the drilling action.
8. If the bit jams in the workpiece or if the drill stalls, stop the tool
immediately. Remove the bit from the workpiece and determine the
reason for jamming.
NOTICE: This drill is equipped with an electric brake. When the brake is
functioning properly, sparks may be visible through the vent slots in the
housing. This is normal and is the action of the brake.
DRILLING MODE OPERATION
1. Select the desired speed to match the planned operation.

2. For wood drilling, use twist bits, spade bits, power auger bits or hole saws.
Begin drilling at a very low speed to prevent the bit from slipping off the
starting point and increase the speed as the drill bit bites into the material.
When drilling “through” holes, place a block of wood behind the workpiece to
prevent ragged or splintered edges on the back side of the hole.
3. For metal drilling, use high speed steel twist drill bits. Begin drilling at a very
low speed to prevent the bit from slipping off the starting point. Maintain a
speed and pressure which allows cutting without overheating the bit. Use
light oil on the drill bit to keep it from overheating; the oil will prolong the
life of the bit and increase the drilling action.
4. If the drill stalls, it is usually because it is being overloaded. Release trigger
switch immediately, remove drill bit from work, and determine cause of stalling.
5. Keep the motor running when pulling the bit back out of drilled hole. This
will prevent jamming.
HAMMER DRILLING MODE OPERATION
1. When hammer drilling, use just enough force on the hammer to keep it from
bouncing excessively. Too much force will cause slower drilling speeds,
overheating and a lower drilling rate.
2. Do not exert side pressure on the bit when drilling, as this will cause
clogging of the bit flutes and reduced drilling speed.
3. If the hammer speed starts to drop off when drilling deep holes, 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 bit or masonry bits. A smooth, even flow of
dust indicates the proper drilling rate.
WARNING: Always wear safety goggles or safety glasses with side shields
during power tool operation or when blowing dust. If operation is dusty, also wear
a dust mask.
SCREWDRIVER OPERATION
1. Select the desired speed/torque range to match the planned operation.
2. Attach the desired fastener accessory into the chuck.
3. Make a few practice runs in scrap piece before working.
