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
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) Electrical 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.
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.
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
designated 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
connection from one terminal to another.
Shorting 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 medical help. Liquid ejected from the
battery may cause irritation or burns.
6) 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.

OPERATING
INSTRUCTIONS
NOTE: Before using the tool, read the
instruction book carefully.
Intended Use
The machine is intended for hammer drilling in
concrete, brick and stone. It is also suitable for drilling
without impact in wood, metal, ceramic and plastic.
Before Putting Into Operation
A) Charging The Battery Pack
The battery pack charger supplied is matched to the Li-
ion battery installed in the machine. Do not use another
battery charger.
The Li-ion battery pack is protected against deep
discharging. When the battery pack is empty, the
machine is switched off by means of a protective circuit:
The chuck no longer rotates.
In a warm environment or after heavy use, the battery
pack may become too hot to permit charging. Allow time
for the battery pack to cool down before recharging.
When the battery pack is charged for the rst time and
after prolonged storage. The battery pack will accept a
100% charge after several charge and discharge cycles.
B) To Remove Or Install Battery Pack (See Fig.
A)
Depress the battery pack release button to release and slide the
battery pack out from your tool. After recharge, slide it

9. OVERLOAD PROTECTION
When overloaded, the motor comes to a stop. Relieve
the load on the machine immediately and allow cooling
for approx. 30 seconds at the highest no-load speed.
10. TEMPERATURE DEPENDENT OVERLOAD
PROTECTION
When using as intended for, the power tool cannot be
subject to overload. When the load is too high or the
allowable battery temperature of 75 °C is exceeded, the
electronic control switches off the power tool until the
temperature is in the optimum temperature range again.
11. PROTECTION AGAINST DEEP DISCHARGING
The Li-ion battery is protected against deep
discharging by the “Discharging Protection System”.
When the battery is empty, the machine is switched off
by means of a protective circuit: The inserted tool no
longer rotates.
WORKING HINTS FOR
YOUR TOOL
If your power tool becomes over heated, set the speed
to maximum and run no load for 2-3 minutes to cool
the motor. SDS-plus tungsten carbide drill bits should
always be used for concrete and masonry.
When drilling in metal, only use HSS drill bits in good
condition. Where possible use a pilot hole before
drilling a large diameter hole.
PROBLEM SOLUTION
1. REASONS FOR DIFFERENT CHARGING TIMES
Your charge time can be affected by many reasons
which are not defects in your product. If the battery
pack is only partly discharged it may be re-charged
in less than 1 hour. If the battery pack and ambient
temperature are very cold then re-charging may take
1-1.5 hours. If the battery pack is very hot it will not re-
charge because the internal temperature safety cutout
will prevent it. If the battery pack is very hot you must
remove your battery pack from the charger and allow
your battery pack to cool rst to ambient temperature
and then recharging can be started. If you charge a
second battery pack immediately after the rst then the
charger can be overheated. Always allow at least 15
minutes rest between battery pack charging.
2. REASONS FOR DIFFERENT BATTERY PACK
WORKING TIMES
Charging time problems, having not used a battery
pack for a prolonged time will reduce the battery pack
working time. This can be corrected after several
charge and discharge operations by charging &
working with your drill. Heavy working conditions such
as large screws into hard wood will use up the battery
pack energy faster than lighter working conditions. Do
not re-charge your battery pack below 0oC and above
30oC as this will affect performance.
MAINTENANCE
REMOVE THE BATTERY PACK FROM THE TOOL
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.
