PRODUCT SAFETY
GENERAL POWER TOOL
SAFETY WARNINGS
WARNING: Read all safety warnings,
instructions, illustrations and
specifications provided 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
atmospheres, such as in the presence of
flammable 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) Elétrical safety
a) 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.
b) 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.
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 residual
current device (RCD) protected supply. Use
of an RCD 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 dust mask, non-skid safety
shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal
injuries.
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 energising 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 control of the power tool in unexpected
situations.
f) Dress properly. Do not wear loose clothing
or jewellery. Keep your hair and clothing
away from moving parts. Loose clothes,
jewellery or long hair can be caught in moving
parts.
g) 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.
h) 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.
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
dangerous and must be repaired.
c) Disconnect the plug from the power
source and/or remove the battery pack,
if detachable, 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.
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 dangerous 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 before 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
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.
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
unexpected situations.
5) Service
a) 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.
DRILL SAFETY
WARNINGS
1) Safety instructions for all operations
a) Wear ear protectors when impact drilling.
Exposure to noise can cause hearing loss.
b) Use auxiliary handle(s). Loss of control can
cause personal injury.
c) Hold the power tool by insulated gripping
surfaces, when performing an operation
where the cutting accessory or fasteners
may contact hidden wiring or its own cord.
Cutting accessory or fasteners contacting a "live"
wire may make exposed metal parts of the power
tool "live" and could give the operator an electric
shock.
2) Safety instructions when using long drill
bits
a) Never operate at higher speed than the
maximum speed rating of the drill bit. At
higher speeds, the bit is likely to bend if
allowed to rotate freely without contacting
the workpiece, resulting in personal injury.
b) 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.
c) 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.

WORKING HINTS FOR
YOUR TOOL
1. For drilling of stones and concrete
Set the hammer/drill control button to the “hammering”
position. Tungsten carbide drill bits are used for rapid
drilling of stones and concrete.
2. For drilling of steel
Set the hammer/drill control button to the “drilling”
position. High-speed steel drill bits are used for drilling
of steel in a slow manner.
3. For locating holes
When drilling large holes in rigid materials such as steel,
it is recommended to drill a small locating hole before
using a large drill bit.
4. For drilling of tiles
Set the hammer/drill button to the “drilling” position.
After penetrating the porcelain, set to the “hammering”
position
5. Cooling motor
If your power tool becomes over heated, set the speed
to maximum and run no load for 2-3 minutes to cool
the motor.

MAINTENANCE
Remove the plug from the socket before
carrying out any adjustment, servicing or
maintenance.
Your power tool requires no additional lubrication or
maintenance.
There are no user serviceable parts in your power
tool. Never use water or chemical cleaners to clean
your power tool. Wipe clean with a dry cloth. Always
store your power tool in a dry place. Keep the motor
ventilation slots clean. Keep all working controls free
of dust. Occasionally you may see sparks through the
ventilation slots. This is normal and will not damage
your power tool.
If the supply cord is damaged, it must be replaced by
the manufacturer, its service agent or similarly qualied
persons in order to avoid a hazard.
PROBLEM SOLUTION
1. If the drill does not work, please check if the power
plug is connected rstly.
2. If the drilling effect is poor, check whether the drill bit
is sharp. If any wear, replace the drill bit. Check whether
the drill is set to “forward rotation” position under
normal use.
3. If it cannot be resolved, please return the drill to your
local dealer for repair.
