Safety precautions

When using the trimmer, the safety instructions must be closely followed. Read this
manual carefully before starting the machine. Make sure that you know how to stop and
switch off the motor in case of an accident. All instructions regarding safety and
maintenance of the machine are for your own safety.

2. GENERAL SAFETY RULES

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.

2.1 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.

4

2.2 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 the cord away from heat, oil, sharp edges and 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 out-door 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.

2.3 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 distraction while operating power tools may result in serious
person al 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 appropriately. Do not wear loose clothing or jewelry. Keep your hair, clothing and
gloves away from moving parts. Loose clothes, jewelry 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.

2.4 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.

5

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.

2.5 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 the 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.

2.6 SERVICE

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.

2.6.1 Grass trimmer safety warnings

1. Keep all parts of the body away from the trimmer line. Do not remove cut material nor
hold material to be cut when the head is moving. Make sure the switch is off when clearing
jammed material. A moment of distraction while operating the trimmer may result in
serious personal injury.

2. Carry the trimmer by the handle. Proper handling of the trimmer will reduce possible
personal injury from the cutter blades.

3. Hold the power tool by the insulated grip surfaces only to protect against potential

6

electric shock.

2.6.2 Additional safety warnings

1. This tool is not intended for use by persons (including children) with reduced physical,

components. Check any parts concerned. Clean such parts or replace them, if required.

8. Use the correct battery only for the intended power tool. Avoid dangerous overloading
of the battery.

2.6.3 Safety Warnings for battery chargers

1. Keep the battery charger away from rain or moisture. Penetration of water in the battery
charger increases the risk of an electric shock.

2. Do not charge other batteries. The battery charger is suitable only for charging lithium
ion batteries within the listed voltage range. Otherwise there is danger of fire and
explosion.

3. Keep the battery charger clean. Contamination can lead to danger of an electric shock.

4. Before each use, check the battery charger, cable and plug. If damage is detected, do
not use the battery charger. Never open the battery charger yourself. Have repairs per­formed only by a qualified technician and only using original spare parts. Damaged battery
chargers, cables and plugs increase the risk of an electric shock.

5. Do not operate the battery charger on easily inflammable surfaces (e. g., paper, textiles,
