GENERAL POWER TOOL SAFETY WARNINGS
WARNING
Read all safety warnings and all 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 mainsoperated (corded) power tool or battery-operated (cordless) power tool.
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.
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 surfaces
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 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 ground fault circuit interrupter
(GFCI) protected supply. Use of a GFCI reduces the risk
of electric shock.
PERSONAL SAFETY
Stay alert, watch what you are doing and use common
sense when operating a power tool. Do not use a power
tool while you are 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.
2 — English
Prevent unintentional starting. Ensure the switch is in
the off-position before connecting to power source
and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or
energising 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 jewel-
lery. Keep your hair, clothing and gloves away from
moving parts. Loose clothes, jewellery or long hair can
be caught in moving parts.
If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection
can reduce dust-related hazards.
Do not wear loose clothing or jewelry. Contain long
hair. Loose clothes, jewelry, or long hair can be drawn
into air vents.
Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of the
power tool in unexpected situations.
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 safer 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.
Maintain power tools. Check for misalignment or bind-
ing 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 main-
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
GENERAL POWER TOOL SAFETY WARNINGS
Use the power tool, accessories and 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.
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.
HAMMER DRILL SAFETY WARNINGS
Wear ear protectors with impact drilling. Exposure to
noise can cause hearing loss.
Use auxiliary handle(s), if supplied with the tool. Loss
of control can cause personal injury.
Hold power tool by insulated gripping surfaces, when
performing an operation where the cutting accessory
may contact hidden wiring or its own cord. Cutting
accessory contacting a “live” wire may make exposed
metal parts of the power tool “live” and could give the
operator an electric shock.
Know your power tool. Read operator’s manual care-
fully. Learn its applications and limitations, as well
as the specific potential hazards related to this tool.
Following this rule will reduce the risk of electric shock,
fire, or serious injury.
Always wear eye protection with side shields marked
to comply with ANSI Z87.1. Following this rule will re-
duce the risk of serious personal injury.
Protect your lungs. Wear a face or dust mask if the
operation is dusty. Following this rule will reduce the
risk of serious personal injury.
Protect your hearing. Wear hearing protection during
extended periods of operation. Following this rule will
reduce the risk of serious personal injury.
Inspect tool cords periodically and, if damaged, have
repaired at your nearest authorized service center.
Constantly stay aware of cord location. Following this
rule will reduce the risk of electric shock or fire.
When servicing a power tool, use only identical re-
placement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts
or failure to follow Maintenance instructions may create
a risk of shock or injury.
Check damaged parts. Before further use of the
tool, a guard or other part that is damaged should
be carefully checked to determine that it will operate
properly and perform its intended function. Check for
alignment of moving parts, binding of moving parts,
breakage of parts, mounting, and any other conditions
that may affect its operation. A guard or other part that
is damaged should be properly repaired or replaced
by an authorized service center. Following this rule will
reduce the risk of shock, fire, or serious injury.
Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one
heavy enough to carry the current your product will
draw. A wire gauge size (A.W.G.) of at least 16 is
recommended for an extension cord 50 feet or less
in length. A cord exceeding 100 feet is not recommended. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord. An
undersized cord will cause a drop in line voltage resulting
in loss of power and overheating.
Inspect for and remove all nails from lumber before
using this tool. Following this rule will reduce the risk of
serious personal injury.
If the power supply cord is damaged, it must be re-
placed only by the manufacturer or by an authorized
service center to avoid risk.
Save these instructions. Refer to them frequently and
use them to instruct others who may use this product. If
you loan someone this product, loan them these instructions also.

ELECTRICAL
DOUBLE INSULATION
Double insulation is a concept in safety in electric power tools, which eliminates the need for the usual threewire grounded power cord. All exposed metal parts are
isolated from the internal metal motor components with
protecting insulation. Double insulated tools do not need
to be grounded.
WARNING:
The double insulated system is intended to protect the
user from shock resulting from a break in the product’s
internal insulation. Observe all normal safety precautions
to avoid electrical shock.
NOTE: Servicing of a product with double insulation requires extreme care and knowledge of the system and
should be performed only by a qualified service technician.
For service, we suggest you return the product to your
nearest authorized service center for repair. Always use
original factory replacement parts when servicing.
ELECTRICAL CONNECTION
This product has a precision-built electric motor. It should
be connected to a power supply that is 120 volts, AC
only (normal household current), 60 Hz. Do not operate
this product on direct current (DC). A substantial voltage
drop will cause a loss of power and the motor will overheat.
If the product does not operate when plugged into an outlet, double-check the power supply.
EXTENSION CORDS
When using a power tool at a considerable distance from
a power source, be sure to use an extension cord that has
the capacity to handle the current the tool will draw. An
undersized cord will cause a drop in line voltage, resulting
in overheating and loss of power. Use the chart to determine the minimum wire size required in an extension cord.
Only round jacketed cords listed by Underwriter’s Laboratories (UL) should be used.
When working outdoors with a product, use an extension
cord that is designed for outside use. This type of cord is
designated with “W-A” or “W” on the cord’s jacket.
Before using any extension cord, inspect it for loose or
exposed wires and cut or worn insulation.

OPERATION
SELECTING HAMMER MODE OR DRILLING
MODE
See Figure 8, page 12.
To adjust for type of drilling, slide the selector on top of the
motor housing to hammer mode or drilling mode. The hammer mode symbol is on the right and the drill bit symbol is
on the left.
NOTE: The hammer drill has not been designed for reverse
hammering.
Use carbide-tipped bits and select hammer mode when
drilling in hard materials such as brick, tile, concrete, etc.
Select normal drill mode when drilling with twist drills, hole
saws, etc., in soft materials.
DRILLING/DRIVING SCREWS
See Figure 9, page 12.
Depress and release the switch trigger to be sure the drill
is in the OFF position before connecting it to a power
supply.
Check the direction of rotation selector for the correct
setting (forward or reverse).
Secure the material to be drilled in a vise or with clamps
to keep it from turning as the drill bit rotates.
Plug the drill into power supply.
Hold the drill firmly and place the bit at the point to be
drilled, or where the screw is to be driven.
WARNING:
Do not drive a screw where there is likely to be hidden
wiring behind the surface. Contact with a “live” wire will
make exposed metal parts of the tool “live” and possibly
shock the operator. If you must drive a screw where hidden wire may be present, always hold tool by insulated
gripping surfaces (handle) when performing the operation
to prevent a shock to the operator.
Depress the switch trigger to start the drill.
Move the drill bit into the workpiece, applying only enough
pressure to keep the bit cutting or driving the screw. Do
not force the drill or apply side pressure to elongate a
hole. Let the tool do the work.
WARNING:
When drilling, be prepared for binding at bit breakthrough.
When these situations occur, the drill has a tendency to
grab and kick in the opposite direction and could cause
loss of control when breaking through material. If not
prepared, this loss of control can result in possible serious injury.
When drilling hard, smooth surfaces, use a center punch
to mark the desired hole location. This will prevent the
drill bit from slipping off-center as the hole is started.
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.
WOOD AND METAL DRILLING
For maximum performance, use high speed steel bits for
wood or metal drilling. Select drilling mode. Begin drilling
at a very low speed to prevent the bit from slipping off the
starting point.
Wood Drilling
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.
Metal and Steel Drilling
Use a 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.
Maintain a speed and pressure which allows cutting
without overheating the bit. Applying too much pressure
will:
• Overheat the drill;
• Wear the bearings;
• Bend or burn bits; and
• Produce off-center or irregular-shaped holes.
When drilling large holes in metal, start with a small bit,
then finish with a larger bit.
MASONRY DRILLING
For maximum performance, use carbide-tipped masonry
impact bits or designated hammer drill bits when drilling
holes in brick, tile, concrete, etc. Select hammer mode.
Apply light pressure at medium speed for best results in
brick.
Apply additional pressure for hard materials such as
concrete.
When drilling holes in tile, practice on a scrap piece to
determine the best speed and pressure. Begin drilling at
a very low speed to prevent the bit from slipping off the
starting point.
