IMPORTANT:
READ ALL INSTRUCTIONS
BEFORE USE.
RETAIN INSTRUCTIONS FOR FUTURE
REFERENCE.
WARNING:
THIS PRODUCT CAN CAUSE SERIOUS
INJURIES.
Read all instructions. Failure to follow
all instructions listed below may result in
electric shock, re 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.
WARNING:
When using any electrical appliance,
basic safety precautions should always be
observed, including the following, to reduce
the risk of re, electrical shock, or injury.
Work area:
•Keep work area clean and well lit.
Cluttered and dark areas invite accidents.
•Do not operate power tools in explosive
atmospheres, such as in the presence of
ammable liquids, gases or dust. Power
tools create sparks which may ignite the
dust and fumes.
•Keep children and bystanders away while
operating a power tool. Distractions can
cause you to lose control.
•Not to be used as a toy. Not to be used
near children. Never allow children to use
the power tool. When not in use store the
power tool out of the reach of children.
•Keep children and bystanders away while
operating the power tool, distractions can
cause you to lose control.
•Always be sure of your footing on ladders
or slopes, do not over-reach or use on
excessively steep slopes.
Electrical safety:
•Power tool plugs must match the outlet.
Never modify the plug in any way.
•Do not use any adaptor plugs with
earthed (grounded) power tools.
Unmodied plugs and matching outlets
will reduce the risk of electric shock.
•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.
•Do not expose power tools to rain or wet
conditions. Water entering a power tool
will increase the risk of electric shock.
•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.
•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.
•If the cord becomes damaged during use
disconnect the cord from the power supply
immediately- DO NOT touch the cable
before disconnecting.
•Before use check the power supply and
charger cables for signs of damage or
ageing.
•When charging or operating the power
tool it is recommended that the appliance
should be supplied via a residual current
device (RCD) with a tripping current of not
more than 30mA.
•Do not handle the charger or the power
tool with wet hands.
Important Safeguards

Personal Safety:
•Stay alert, watch what you are doing
and use common sense when operating
a power tool. Do not use any power tool
while you are tired or under the inuence
of drugs, alcohol or medication. A moment
of inattention while operating power tools
may result in serious personal injury.
•Always be aware of your surroundings
and stay alert for possible hazards
that you may not be aware of due to
concentration on the power tool.
•Use safety equipment. Always wear eye
protection. Safety equipment such as non
skid shoes, safety glasses, sturdy gloves
and hearing protection are recommended
and will reduce the risk of personal injury.
•Do not operate when barefoot or wearing
open sandals.
•Always wear substantial footwear and
long trousers.
•Dress appropriately. 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.
•Avoid accidental starting. Ensure the
switch is in the off position before plugging
in. Carrying power tools with your ngers
on the switches or plugging in power tools
that have the switch on invites accidents
•Remove any adjusting key or wrench
before starting the power tool. A key or
wrench left in a rotating part of the power
tool may result in personal injury.
•Do not overreach. Keep proper footing
and balance at all times. This enables
better control of the power tool in
unexpected situations
•Take care in slippery conditions, and on
slopes and uneven ground.
•Do not run with the power tool.
•When operating the power tool ensure
that both hands are correctly positioned
on both handles. Do not operate this

•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.
•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.
•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 measure reduce the risk of starting
the power tool accidentally,
•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.

untrained users.
•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.
•Check that the cutting blades are clean
and without damage. If the blade becomes
worn a replacement should be tted
before use.
•Use the power tool, accessories etc. In
accordance with these instructions and
