3. Personal safety
General safety rules
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.
WARNING. Read all instructions. Failure to follow all
instructions listed below may result in electric shock, fire and/
or serious injury. The term “power tool” in all of the warnings
listed below refers to your mains operated (corded) power
tool or battery operated (cordless) power tool.
Save these instructions
1. Work area
b. Use safety equipment. Always wear eye protection.
Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
a. Keep work area clean and well lit. Cluttered and 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. Avoid accidental starting. Ensure the switch is in the
off position before plugging in. Carrying power tools with
your finger on the switch or plugging in power tools that
have the switch on invites accidents.
c. Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
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.
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.
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.
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.
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.
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.
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.
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.

c. Disconnect the plug from the power source before
making any adjustments, changing accessories, or
storing power tools. Such preventive safety measures
reduce the risk of starting the power tool accidentally.
d. 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. 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. 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.
e. Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may affect the power tools
operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools.
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.
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.
Additional safety rules for drills
• Wear ear protectors with impact drills. Exposure to
noise can cause hearing loss.
g. Use the power tool, accessories and tool bits etc.,
in accordance with these instructions and in the
manner intended for the particular type of power
tool, taking into account the working conditions and
the work to be performed. Use of the power tool for

Hints for use
Maintenance
• When driving screws close to the ends of hardwoood or
treated timber boards it may be necessary to pre-drill pilot
holes to prevent spitting.
WARNING. Ensure that the
tool is switched off and the
battery is removed before
changing accessories or
carrying out other adjustment
or maintenance procedures.
• Use the proper screws for the task on hand. Drywall
screws are not suitable for decking applications.
• Make sure that screws are long enough to ensure a
secure fastening.
Keep the tool’s air vents
unclogged and clean at all times.
• Use the low speed gear when driving into decking and
the like, and the high speed gear when driving into
drywalls.
Regularly check to see if any dust or foreign matter has
entered the grills near the motor and around the trigger
switch. Use a soft brush to remove any accumulated dust.
Wear safety glasses to protect your eyes whilst cleaning.
• Once the screw has started to drive into the material, do
not stop until it is fully seated. Keep full pressure of the
bit on the screw head to prevent slippage and possible
damage to the screw head or bit.
Re-lubricate all moving parts at regular intervals.
If the body of the tool needs cleaning, wipe it with a soft
damp cloth. A mild detergent can be used but nothing like
alcohol, petrol or other cleaning agent.
• Before driving deck screws check that there is not gap
between the board and the support.
Never use caustic agents to clean plastic parts.
• Do not drive through knots in the wood unless absolutely
necessary. If there is no choice, pre-drill a pilot hole to the
same diameter as that of the screw shank.
CAUTION. Water must never come into contact with
the tool.
General inspection
Regularly check that all the
fixing screws are tight. They
may vibrate loose over time.
