injury or death for the operator or bystanders if the instructions in the manual are not obeyed. CAUTION: Used if there is a risk of damage to the product, other materials or the adjacent area if the instructions in the manual are not obeyed. Note: Used to give more information that is necessary in a given situation. Work area safety

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.

• Do not operate machines in explosive atmospheres, such as in the presence of flammable liquids, gases or dust.Machines create sparks which may ignite the dust or fumes.

• Keep children and bystanders away while operating a machine. Distractions can cause you to lose control. Electrical safety

• Machine plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) machines. 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 machines to rain or wet conditions. Water entering a machine will increase the risk of electric shock.

• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the machine. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

• When operating a machine 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 machine in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of a RCD reduces the risk of electric shock. Personal safety

• Stay alert, watch what you are doing and use common sense when operating a machine. Do not use a machine while you are tired or under the

790 - 012 - 06.05.2025

7influence of drugs, alcohol or medication. A moment of inattention while operating machines 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 and/or battery pack, picking up or carrying the machine. Carrying machines with your finger on the switch or energising machines that have the switch on invites accidents.

• Remove any adjusting key or wrench before turning the machine on. A wrench or a key left attached to a rotating part of the machine may result in personal injury.

• Do not overreach. Keep proper footing and balance at all times. This enables better control of the machine in unexpected situations.

• Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing 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.

• Do not let familiarity gained from frequent use of machines allow you to become complacent and ignore machine safety principles. A careless action can cause severe injury within a fraction of a second. Machine use and care

• Do not force the machine. Use the correct machine for your application. The correct machine will do the job better and safer at the rate for which it was designed.

• Do not use the machine if the switch does not turn it on and off. Any machine that cannot be controlled with the switch is dangerous and must be repaired.

• Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the machine before making any adjustments, changing accessories, or storing machines. Such preventive safety measures reduce the risk of starting the machine accidentally.

• Store idle machines out of the reach of children and do not allow persons unfamiliar with the machines or these instructions to operate the machines. Machines are dangerous in the hands of untrained users.

• Maintain machines and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the machines´s operation. If damaged, have the machine repaired before use. Many accidents are caused by poorly maintained machines.

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

• Use the machine, accessories and bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the machine for operations different from those intended could result in a hazardous situation.

• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the machine in unexpected situations. Battery machine use and care

• 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.

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

• 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.

• 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 irritations or burns.

• Do not use a battery pack or machine that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.

• Do not expose a battery pack or machine to fire or excessive temperature. Exposure to fire or temperature above 130 °C / 265 °F may cause explosion.

• Follow all charging instructions and do not charge the battery pack or machine outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire. Service

• Have your machine serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the machine is maintained.

• Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

blower/vacuum safety warnings
