Careful handling and use of batteries

•  Observe the special guidelines applicable to the transport, storage and use of lithium-ion batteries.

 Additional safety instructions for vacuum cleaners

Work area safety
Keep bystanders, children and visitors away while operating the power tool. Distractions may cause you to lose control of the tool.
Electrical safety

•  Avoid body contact with earthed / grounded surfaces such as pipes, radiators, cookers, stoves and refrigerators. There is an increased risk of electric shock if your body is grounded.
•  Do not expose the vacuum cleaner to rain or wet conditions. Water entering a vacuum cleaner will increase 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 the power tool may result in serious personal injury.
• Wear your personal protective equipment and always wear protective glasses. Depending on the type of power tool you are using and its purpose, wearing safety equipment such as a dust mask, slip-resistant safety shoes, a hard hat or hearing protection will reduce the risk of injury.
• Do not use the vacuum cleaner in extremely dusty conditions.
•  Misuse can result in liquid escaping from the battery. Avoid contact with the liquid. Liquid escaping from the battery can cause skin irritation or burns. If contact occurs, rinse off with water. In the event of the liquid coming into contact with the eyes, rinse the eyes with plenty of water and consult a doctor.

Using and handling the power tool

•  Store power tools out of reach of children when not in use. Do not allow persons who are not familiar with the tool or these instructions to operate it. Power tools are dangerous in the hands of inexperienced persons.
•  Take good care of the power tool. Check that moving parts operate satisfactorily and do not jam, and make sure that no parts are broken or damaged in such a way that the power tool might no longer function correctly. Have damaged parts repaired before using the tool. Many accidents are caused by poorly maintained power tools.
•  Use power tools, accessories, insert tools, etc. in accordance with these instructions. Take the working conditions and the work to be performed into account. Use of power tools for applications other than those intended can result in hazardous situations.
• Use the right appliance for the job. Do not use the appliance for purposes for which it was not intended. Use it only as directed and when in faultless condition.
•  Do not use the vacuum cleaner as a dust extractor in combination with other electric appliances.
•  Operate the vacuum cleaner only with the filter installed.
• Avoid unintentional starting. Switch the device off before inserting the battery and before lifting or transporting the device. Never carry the device with your finger on the control switch. Always remove the battery when the device is not in use, before maintenance, before changing accessory tools and in preparation for and throughout transport.
• Do not sit or stand on the appliance.

Service

•  Have the power tool repaired only by a qualified specialist using only genuine Hilti spare parts. The safety of the power tool can thus be maintained.
