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, clothing and gloves 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 these devices 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 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.
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. 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.

condition. Where possible use a pilot hole
before drilling a large diameter hole.
PROBLEM SOLUTION
1. 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 tool. 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, except for the
cleaning & lubrication of the SDS bits and
adaptors before inserting into the chuck.
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.
DISPOSAL OF AN
EXHAUSTED BATTERY
PACK
To preserve natural resources, please
recycle or dispose of the battery
pack properly. This battery pack
contains Li-ion batteries. Consult your local
waste authority for information regarding
available recycling and/or disposal options.
Discharge your battery pack by operating
your tool, then remove the battery pack
from the tool housing and cover the battery
pack connections with heavy-duty adhesive
tape to prevent short circuit and energy
discharge. Do not attempt to open or remove
any of the components.
