General Power Tool Safety Warnings
Read all safety warnings, instructions, illustrations and specifications provid-
ed with this power tool. Failure to follow all instructions listed below 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
a. Keep work area clean and well lit. Cluttered
or dark areas invite accidents.
b. Do not operate power tools in explosive at-
mospheres, such as in the presence of flam-
mable liquids, gases or dust. Power tools
create sparks which may ignite the dust or
fumes.
c. Keep children and bystanders away while
operating a power tool. Distractions can
cause you to lose control.
2. Electrical safety
a. Power tool plugs must match the outlet. Nev-
er 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.
b. Avoid body contact with earthed or ground-
ed surfaces, such as pipes, radiators, ranges
and refrigerators. There is an increased risk
of electric shock if your body is earthed or
grounded.
c. Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
d. 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.
e. 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.
f. If operating a power tool in a damp location
is unavoidable, use a Ground Fault Circuit In-
terrupter (GFCI) protected supply. Use of an
GFCI reduces the risk of electric shock.
3. Personal safety
a. 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.
b. Use personal protective equipment. Always
wear eye protection. Protective equipment
such as a dust mask, non-skid safety shoes,
hard hat, or hearing protection used for ap-
propriate conditions will reduce personal in-
juries.

page headingGeneral Power Tool Safety Warnings
c. 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 energizing
power tools that have the switch on invites
accidents.
d. 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.
e. Do not overreach. Keep proper footing and
balance at all times. This enables better con-
trol of the power tool in unexpected situa-
tions.
f. 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.
g. If devices are provided for the connection of
dust extraction and collection facilities, en-
sure these are connected and properly used.
Use of dust collection can reduce dust-related
hazards.
h. Do not let familiarity gained from frequent
use of tools allow you to become compla-
cent and ignore tool safety principles. A
careless action can cause severe injury within
a fraction of a second.
4. Power tool use and care
a. 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.
b. 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 dan-
gerous and must be repaired.
c. Disconnect the plug from the power source
and/or remove the battery pack, if detach-
able, from the power tool before making any
adjustments, changing accessories, or stor-
ing power tools. Such preventive safety mea-
sures reduce the risk of starting the power
tool accidentally.
d. 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 dan-
gerous in the hands of untrained users.
e. Maintain power tools and accessories. 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 be-
fore use. Many accidents are caused by poorly
maintained power tools.
f. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.
g. Use the power tool, accessories and tool
bits etc. in accordance with these instruc-
tions, taking into account the working condi-
tions and the work to be performed. Use of
the power tool for operations different from
those intended could result in a hazardous
situation.
h. Keep handles and grasping surfaces dry,
clean and free from oil and grease. Slippery
handles and grasping surfaces do not allow
for safe handling and control of the tool in un-
expected situations.
5. Battery tool use and care
a. 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.
b. Use power tools only with specifically desig-
nated battery packs. Use of any other battery
packs may create a risk of injury and fire.
c. When battery pack is not in use, keep it
away from other metal objects like paper
clips, coins, keys, nails, screws, or other
small metal objects that can make a con-
nection from one terminal to another. Short-
ing the battery terminals together may cause
burns or a fire.
d. 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 medi-
cal help. Liquid ejected from the battery may
cause irritation or burns.
e. Do not use a battery pack or tool that is
damaged or modified. Damaged or modified
batteries may exhibit unpredictable behaviour
resulting in fire, explosion or risk of injury.
f. Do not expose a battery pack or tool to fire
or excessive temperature. Exposure to fire or

General Power Tool Safety Warnings
temperature above 265 °F may cause explo-
sion.
g. Follow all charging instructions and do not
charge the battery pack or tool outside the
temperature range specified in the instruc-
tions. Charging improperly or at temperatures
outside the specified range may damage the
battery and increase the risk of fire.
6. Service
a. Have your power tool serviced by a qualified
repair person using only identical replace-
ment parts. This will ensure that the safety of
the power tool is maintained.
b. Never service damaged battery packs. Ser-
vice of battery packs should only be per-
formed by the manufacturer or authorized
service providers.
Wear ear protectors. 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 surfac-
es, when performing an operation where the
cutting accessory may contact hidden wiring.
Cutting accessory contacting a “live” wire may
make exposed metal parts of the power tool
“live” and could give the operator an electric
shock.
Use clamps or another practical way to secure
and support the workpiece to a stable plat-
form. Holding the work by hand or against your
body leaves it unstable and may lead to loss of
control.
Do not drill, fasten or break into existing walls
or other blind areas where electrical wiring
may exist. If this situation is unavoidable, dis-
connect all fuses or circuit breakers feeding this
worksite.
Always wear safety goggles or eye protection
when using this tool. Use a dust mask or respi-
rator for applications which generate dust.
Use a metal detector to determine if there are
gas or water pipes hidden in the work area or
call the local utility company for assistance
before beginning the operation. Striking or
cutting into a gas line will result in explosion.
Water entering an electrical device may cause
electrocution.
Always use the side handle for maximum con-
trol over torque reaction or kick-back. Never
attempt to operate this tool with one hand. The
slip clutch engages if you firmly control the tool
during a torque reaction or kickback.
Use thick cushioned gloves and limit the ex-
posure time by taking frequent rest periods.
Vibration caused by hammer-drill action may be
harmful to your hands and arms.
Secure the material being drilled. Never hold
it in your hand or across legs. Unstable support
can cause the drill bit to bind causing loss of
control and injury.
Disconnect battery pack from tool before mak-
ing any assembly, adjustments or changing
accessories. Such preventive safety measures
reduce the risk of starting the tool accidentally.
Position yourself to avoid being caught be-
tween the tool or side handle and walls or
posts. Should the bit become bound or jammed
in the work, the reaction torque of the tool could
crush your hand or leg.
If the bit becomes bound in the workpiece,
release the trigger immediately, reverse the
direction of rotation and slowly squeeze the
trigger to back out the bit. Be ready for a strong
reaction torque. The drill body will tend to twist
in the opposite direction as the drill bit is rotat-
ing.
Do not strike the bit with a handheld hammer
or sledgehammer when attempting to dislodge
a bound or jammed bit. Fragments of metal
from the bit could dislodge and strike you or
bystanders.
Never place the tool down until the bit or ac-
cessory has come to a complete stop.
Do not grasp the tool or place your hands too
close to the spinning chuck or drill bit. Your
hand may be lacerated.

When installing a drill bit, insert the shank of
the bit well within the jaws of the chuck. If the
bit is not inserted deep enough, the grip of the
jaws over the bit is reduced and the loss of con-
trol is increased.
Do not use dull or damaged bits and accesso-
ries. Dull or damaged bits have a greater ten-
dency to bind in the workpiece.
When removing the bit from the tool avoid con-
tact with skin and use proper protective gloves
when grasping the bit or accessory. Accesso-
ries may be hot after prolonged use.
Check to see that keys and adjusting wrenches
are removed from the drill before switching
the tool “ON”. Keys or wrenches can fly away at
high velocity striking you or a bystander.
Do not run the tool while carrying it at your
side. A spinning drill bit could become entan-
gled with clothing and injury may result.
If devices are provided for the connection of
dust collection and extraction systems, empty
the dust container before beginning work, fre-
quently during work, after completion of work,
and before storing the tool. Be extremely care-
ful of dust disposal, materials in fine particles
form may be explosive.
Do not throw dust on an open fire. Combustion
from mixture of varnishes, lacquers, polyure-
thane, oil or water with dust particles can occur
if there is a static discharge, electric spark, or
excessive heat.
Do not use dust extraction for operations
where dust may include burning, smoking or
smoldering items like hot ashes or sparks. Fire
inside the vacuum tank or bag may occur. Dust
may smolder and set vacuum on fire long after
work is completed.
Do not use dust extraction with explosive
dusts, varnish, polyurethane coatings, clean-
ers, or oil-based paints. Electric motors create
sparks which may ignite the dust or fumes.
Do not use dust extraction when working on
metal. Swarf from drilling metal may be hot and
may spark which may melt plastic adaptors,
vacuum hoses and may cause a fire inside the
vacuum tank or bag.
Do not drill into metal with the dust extraction
system mounted. Hot metal chips can self-ignite
or ignite parts of the dust extraction system.
Do not drill into wood with dust extraction sys-
tem mounted. Wood chips are typically too large
and will clog the dust channel.
Your tool is equipped with a dust canister,
empty it frequently, after completion of drill-
ing and before storing the tool. Be extremely
careful of dust disposal, materials in fine par-
ticle form may be explosive.
Note: Do not use the dust extraction system
when chiselling, screwdriving or cutting threads.
Safety instructions when using
long drill bits with rotary hammers
a. Always start drilling at low speed and with
the bit tip in contact with the workpiece.
At higher speeds, the bit is likely to bend if
allowed to rotate freely without contacting
the workpiece, resulting in personal injury.
b. Apply pressure only in direct line with the
bit and do not apply excessive pressure.
Bits can bend causing breakage or loss of
control, resulting in personal injury.
c. Never operate at higher speed than the
maximum speed rating of the drill bit. At
higher speeds, the bit is likely to bend if al-
lowed to rotate freely without contacting the
workpiece, resulting in personal injury.

page headingAdditional Safety Warnings
GFCI and personal protection devices like elec-
trician’s rubber gloves and footwear will further
enhance your personal safety.
Do not use AC only rated tools with a DC power
supply. While the tool may appear to work, the
electrical components of the AC rated tool are
likely to fail and create a hazard to the operator.
Keep handles dry, clean and free from oil and
grease. Slippery hands cannot safely control the
power tool.
Develop a periodic maintenance schedule for
your tool. When cleaning a tool be careful not
to disassemble any portion of the tool since
internal wires may be misplaced or pinched or
safety guard return springs may be improperly
mounted. Certain cleaning agents such as gaso-
line, carbon tetrachloride, ammonia, etc. may
damage plastic parts.
Ensure the switch is in the off position before
inserting battery pack. Inserting the battery
pack into power tools that have the switch on
invites accidents.
Some dust created by power
sanding, sawing, grinding,
drilling, and other construction activities con-
tains chemicals known to cause cancer, birth
defects or other reproductive harm. Some ex-
amples of these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement and
other masonry products, and
• Arsenic and chromium from chemically-treat-
ed lumber.
Your risk from these exposures varies, depend-
ing on how often you do this type of work. To re-
duce your exposure to these chemicals: work in
a well ventilated area, and work with approved
safety equipment, such as those dust masks
that are specially designed to filter out micro-
scopic particles.
