IMPORTANT: FOR YOUR OWN
SAFETY AND BYSTANDERS READ
THE INSTRUCTIONS BEFORE
OPERATING THE MACHINE.

PLEASE KEEP THE INSTRUCTIONS SAFE
FOR FUTURE REFERENCE.

WARNING: When using the machine the
safety instructions must be followed.

WARNING: THIS PRODUCT CAN CAUSE
SERIOUS INJURIES.

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.

WARNING: When using any electrical
appliance, basic safety precautions should
always be observed, including the following, to
reduce the risk of fire, 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
flammable 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.

• 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.

• Unmodified 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.

• 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. NOTE:
The term residual current device (RCD)” may
be replaced by the term “ground fault circuit
interrupter (GFCI)” or “earth leakage circuit
breaker (ELCB)”

• 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.

• Before use check the power supply and
charger cord for signs of damage or ageing.
To avoid damage it is not recommended to
wrap the cord around the charger. A damaged
charger cord can increase the risk of fire and
electric shock.

• Do not abuse the charger cord as this can
increase the risk of fire and electric shock.
Never carry the charger or battery by the cord.
Do not pull the cord to disconnect the charger
from an electrical outlet.

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 influence

• 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 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 innjuries.

• 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.

• Prevent unintentional starting. Ensure the switch
is in the off-position before connecting to power
source and/or battery pack, pick up or carrying
the tool. Carrying power tools with your fingers
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 product if
incomplete or with unauthorized modifications.

• Keep hands and feet away from the cutting
element at all times, and especially when
switching on.

• Warning, the cutting element will continue to
move after the motor is switched off.

• Ensure that the motor has fully stopped and
the battery/mains supply is disconnected
before cleaning, clearing a blockage,
checking, or carrying out maintenance on the
power tool.

• Never operate the power tool with damaged
guards or without the guards in place.

• The operator or user is responsible for
accidents or hazards occuring to other people
at their property.

• Never fit metal cutting elements.

• This appliance is not intended for use by
persons (including children) with reduced
physical, sensory or mental capabilities,
or lack of experience and knowledge,
unless they have been given supervision or
instruction concerning use of the appliance by
a person responsible for their safety.

• Children should be supervised to ensure that
they do not play with the appliance.

• Take care against any device fitted for
trimming the filament line length. After
extending a new cutter line always return
the machine to its normal operating position
before switching on.

• If devices are provided for the connection of dust
extraction and collecton facilities, ensure that
these are connected and properly used. Use of
dust collection can reduce dust-related hazards.

Power tool use and care:

• 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. Power tools are dangerous in the
hands of 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 fitted before use.

• Keep cutting tools sharp and clean. Properly
maintained cutting toolswith sharp cutting edges
are less likely to bind and are easier to control.

• Use the power tool, accessories etc. In
accordance with these instructions and inthe
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 operations different from those intended
could result in a hazardous situation.

• Only use the machine in daylight or good
artificial light.

• Before using the machine and after any
impact, check for signs of wear or damage
and repair as necessary.

• Always ensure that ventilation openings are
kept clear of debris.

• Keep the product and all accessories away
from hot surfaces.

• Store the tool in a secure, dry place out of
reach of children and animals.

• Never modify the trimmer in any way as this
may increase the risk of personal injury.

Battery use and care:

• Recharge only with the charger specified by
the manufacturer. A charger that is suitable

for one type of battery may create a risk of fire
when used with another battery pack.

• Using a charger from a different product may
cause a risk of fire.

• Leaks from battery cells can occur under
extreme conditions. If the liquid gets on the
skin wash immediately with soap and water.
If the liquid gets into the eyes, flush them
immediately with clean water for a minimum of
10 minutes and seek medical attention.

• This product contains Ni-Cd batteries. Do
not incinerate batteries or expose to high
temperatures, as they may explode.

• Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.

• When the battery pack is not in use, keep
away from other metal objects such as: 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 may cause burns or fire.

• In an emergency situation contact professional
help immediately!

• 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 a battery may cause
irritation or burns.

Cutting and edging

Caution: before use remove any stones, loose debris and other objects from the
cutting area.

Always take care when other people are around you.

The trimmer may throw out stones and debris at high speed.

WARNING: Always wear eye protection when using the trimmer.

Take care not to overload the trimmer. Attempting to force the trimmer to cut may damage the
motor. To prevent overloading cut long or difficult foliage in stages with several light cuts.

NOTE: the trimmer is fitted with a self-resetting protective cut-out. This will stop the
trimmer if the motor becomes overloaded. If this occurs, wait a few seconds for the
cut-out to reset and then use lighter cuts.

Take care not to grind the rotating parts against the ground as this will wear parts and cause
damage to the trimmer.

Take care when trimming around objects such as stone or concrete as these can damage the
trimmer blade and parts that attach the blade.

WARNING: Do not hold the guard or cutting head when using the product. Keep
hands clear of the rotating blades and cutting area.

Care and maintenance

To ensure long and reliable service, carry out the following maintenance regularly:

Check for obvious defects such as loose, dislodged, worn or damaged parts.

Before use, visually check the condition of the cutting blades. If worn replace with fresh blades.

Clean inside the cutting guard after use. Remove any dirt or debris using a suitable wooden
or plastic tool. Do not use water, solvents, or polishes to clean the trimmer. Wipe clean with a
dry cloth.

Store in a dry place away from children.

Do not expose to moisture.

It is not necessary to oil the product.

When storing the trimmer for longer then 6 weeks
