General Power Tool Safety Warnings
WARNING
• Read all safety warnings, instructions, illustrations and specications provided with
this power tool.Failure to follow all instructions listed below may result in electric shock,
re 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.
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
ammable 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. Unmodied plugs and matching
outlets will reduce the 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.

6
SAFETY INFORMATION
• Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase 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 inuence of drugs,
alcohol or medication. A moment of inattention while operating power tools may result in
serious personal injury.

such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for
appropriate conditions will reduce personal injuries.
• 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 nger 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 jewelry. Keep your hair and clothing 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 these are connected and properly used. Use of dust collection can reduce dust-
related hazards.
• Do not let familiarity gained from frequent use of tools allow you to become
complacent and ignore tool safety principles. A careless action can cause severe injury
within a fraction of a second.
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 remove the battery pack,

OPERATING INSTRUCTIONS
Drilling Wood
a. For maximum performance, use high-speed steel or brad-point bits for drilling wood.
b. Set the mode selector (C) to drilling mode for best performance.
c. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
d. Increase speed as the drill bit bites into the material.
e. When drilling “through” holes, place a block of wood behind the work piece to prevent
ragged or splintered edges on the back side of the hole.
NOTICE: When drilling deep holes, the bit may overheat. Change the direction of rotation and
pull out the bit frequently to clear wood chips from utes.
Drilling Metal
a. For maximum performance, use high-speed steel bits for drilling metal or steel.
b. Set the mode selector (C) to drilling mode for best performance.
c. 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 efciency.
d. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
e. Maintain a speed and pressure which will allow cutting without overheating the bit.
Applying too much pressure will:
•Overheat the tool.
•Wear the bearings.
•Bend or burn bits.
•Produce off-center or irregularly-shaped holes.
Masonry Drilling
a. For maximum performance, use carbide-tipped masonry bits when drilling holes in brick,
concrete, etc.
b. Set the mode selector (C) to hammer mode or best performance.
c. Maintain a speed and pressure which will allow cutting without overheating the bit or the
tool. Applying too much pressure will:
•Overheat the tool.
•Wear the bearings.
•Bend or burn bits.
•Produce off-center or irregularly-shaped holes.
d. Apply light pressure and medium speed for best results in brick.
e. Apply additional pressure for hard materials, such as concrete.
f. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.

16
OPERATING INSTRUCTIONS
14. Driving Screws
Try to use standard-type screws for easy driving
and improved grip.
a. Install the correct driver bit.
b. Set the mode selector (C) to driving mode
for best performance.
c. Ensure that the torque-adjustment ring is set to
the most suitable setting. If in doubt, start with
a low setting and gradually increase the setting
as necessary. Do not change the torque setting
when the tool is running.
d. Use the correct speed range for the job and
initially apply minimal pressure to the variable-
speed trigger switch. Increase the speed only
when full control can be maintained.
e. It is advisable to drill a pilot hole rst. This hole should be slightly longer than the screw
to be driven and slightly thinner than the shank diameter of the screw. The pilot hole will
act as a guide for the screw and will also make tightening the screw less difcult. When
screws are positioned close to an edge of the material, a pilot hole will also help to prevent
splitting of the wood.
f. Use a countersinking bit (sold separately) to accommodate the screw head so that it does
not protrude from the surface.
g. Keep sufcient pressure on the drill to prevent the bit from turning out of the screw head.
The screw head can easily become damaged, making it difcult to drive home or remove.
h. To stop the hammer drill, release the trigger switch and allow the tool to come to a
complete stop.
