General Power Tool Safety Warnings

Caution!
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.

Caution!
Use the equipment only if it is in correct operating condition! Before using, check the machine, cable and plug for damage; any damaged parts must be repaired or replaced at a specialised repair centre.

Caution - Danger of electrocution!
If the cable has been cut or is damaged, disconnect the plug from the mains supply immediately.

Caution - Risk of injury!
Safety/protection devices should not be disabled!

Warning!
The vibration emission during actual use of the power tool can differ from the declared total value depending on the ways in which the tool is used.

Caution!
Only hold the electrical equipment on the insulated grip areas as the cutting blade may come into contact with concealed power lines or with the mains cable itself.
The cutting blade coming into contact with a live cable may make parts of the equipment live and result in an electric shock.
Work area safety
- Keep work area clean and well lit. Cluttered or 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 or fumes.
- Keep children and bystanders away while operating a power tool.
Distractions can cause you to loose control.
Electrical safety
■ 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.
- 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 and 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 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
Personal safety
■ 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.
■ 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.
■ Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source, 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.
■ 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.
Do not overreach. Keep proper footing and balance at all times.
This enables better control of the power tool in unexpected situations.
■ 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.
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.
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 tool 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.
■ 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 tool's operation. If damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power tools.
- Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
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.
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.
Safety Instructions for operation
■ Always operate the machine with both hands.
- Observe local regulations regarding minimum age requirements for operating the machine.
Children and persons who are not familiar with these operating instructions are not permitted to use the mower
This tool is not intended to be used by people (including children) who have restricted physical, sensory or mental capabilities; neither is it intended to be used by people lacking experience and/or knowledge unless they are supervised by someone who is responsible for safety, or receive instructions from this supervisory person in how to operate the tool. Children should be supervised in order to make sure that they do not play with the tool.
- Keep body and clothing away from cutting parts.
- Do not remove cut material while the motor is running.
■ When leaving unattended / transporting the machine:
■ Switch the machine off.
Pull out the mains plug.
■ Push on the safety cover.
■ Never hold the machine by the blade.
■ Only carry the machine by the hand grip.
The domestic mains voltage must match the mains voltage specifications in the technical data.
■ Always use the special cable strain relief for the extension lead.
■ Always keep the cable out of the cutting area and routed away from the machine.
Assembly
- Fasten the handguard to the housing using the screws supplied (1).
- Feed the extension cable through the strain relied clamp (2 / 3).
Operation
Caution - Risk of injury! Use the equipment only after it has been completely assembled. Follow the safety instructions when working.
- Connect the power cable to the mains supply.
- Grasp the front hand grip first, then the rear hand grip.
- Press the power switches on both hand grips (4) - the machine will start.
- Keep both switches pressed while working.
- If one of the switches is released, the hedge trimmer stops.
Instructions when working
■ Always cut both sides of the hedge first, then the top. This will prevent cut leaves and twigs from falling into an area not yet trimmed
■ You can use the built-in spirit level to cut along a straight line (5)
Hedges should always be cut in a trapezoid shape. This prevents the lower twigs from becoming bare (8)
Repairs
■ Repairs should be carried out only by a specialised repairer, or at one of our AL-KO service centres
Maintenance and care

Caution - Danger of electrocution!
Always disconnect the mains plug when carrying out maintenance or repair work!
