Safety

General safety instructions

In addition to the safety instructions given in the various sections of these operating instructions, the following points must be strictly observed at all times.
Read all the instructions. Failure to follow all the instructions listed below may result in electric shock, fire and/or serious injury.

•  If the appliance is used in conjunction with an electric tool, read and follow the operating instructions for the electric tool and all the warnings.
•  Modification of the appliance is not permitted.
•  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.
•  Before beginning work with the appliance, find out how to operate it correctly and about any hazards associated with the materials it will be picking up and how these materials can be disposed of.
•  Take the influences of the surrounding area into account. Do not use the appliance where there is a risk of fire or explosion.
•  The appliance may only be used by persons who are familiar with it, have been trained on how to use it safely and who understand the resulting hazards. The appliance is not intended for use by children.
•  Store appliances in a secure place when not in use. When not in use, appliances must be stored in a dry, high place or locked away out of reach of children.

Electrical safety

•  The plug on the supply cord of the appliance must match the outlet. Do not change the plug in any way. Do not use adapter plugs with earthed (grounded) appliances. Unmodified plugs and matching outlets reduce risk of electric shock.
•  Insert the plug in a suitable earthed/grounded power outlet which has been correctly and safely installed and is in compliance with local regulations. If you are in doubt about the effectiveness of the power outlet’s earth/ground connection, have it checked by a qualified specialist.
•  Avoid body contact with earthed or 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 appliance to rain. Water entering an electric appliance will increase the risk of electric shock.
•  Check to ensure that the supply cord does not lie in a puddle of water.
•  Check the appliance’s supply cord at regular intervals and have it replaced by Hilti Service if damage is found. Check extension cords at regular intervals and replace them if found to be damaged.
•  Do not touch the supply cord or extension cord if they are damaged while working. Disconnect the supply cord plug from the power outlet. Damaged supply cords or extension cords present a risk of electric shock.
•  The electric supply cord may be replaced only with a cord of the type specified in the operating instructions.
•  Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the appliance. Keep the cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
•  When operating an electric appliance outdoors, use only extension cords of a type suitable for outdoor use. Use of an extension cord suitable for outdoor use reduces the risk of electric shock.
•  In the event of an interruption in the electric supply, switch the appliance off and unplug it from the power outlet.
•  Use the built-in power outlet only for tools with ratings in the range for which the socket is rated.
•  Never operate the appliance when it is dirty or wet. Dust (especially dust from conductive materials) or dampness adhering to the surface of the appliance may, under unfavorable conditions, lead to electric shock. Dirty or dusty appliances should thus be checked by Hilti Service at regular intervals, especially if used frequently for working on conductive materials.

Personal safety

•  Stay alert, watch what you are doing and use common sense when operating the device. Do not use the tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating the tool may result in serious personal injury.
•  The user and any other persons in the vicinity must wear suitable eye protection, a hard hat, ear protection, protective gloves, safety footwear and breathing protection while the appliance is in use or while maintenance work on it is being carried out.
•  Make sure that the workplace is well ventilated and, where necessary, wear a respirator appropriate for the type of dust generated. Contact with or inhalation of the dust may cause allergic reactions and/or respiratory or other diseases among operators or bystanders. Certain kinds of dust are classified as carcinogenic such as oak and beech dust, especially in conjunction with additives for wood conditioning (chromate, wood preservative). Material containing asbestos may be handled only by specialists.
•  Engage the wheel brakes so that the tool stands securely. If the wheel brakes are not locked, the tool can begin to roll unchecked.
•  If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of a vacuum cleaner can reduce dust-related hazards.

Safety instructions for use

•  Before beginning work, the operating personnel must be informed on using the tool, on any hazards associated with the material and on the safe disposal of the material vacuumed up.
•  Use of the appliance to clean down persons or animals is not permissible.
•  Do not use the device for stationary, steady-state operation in automatic or semi-automatic systems.•
• Do not use the tool casing as a substitute for a ladder.
•  Do not use the tool under water.

The material picked up

•  Do not use the appliance to pick up flammable or explosive dusts (magnesium or aluminum dust etc.) or dusts that present a health hazard. Do not use the appliance to pick up materials with a temperature of over 60 °C (e.g. glowing cigarettes, hot ash).
•  Do not use the appliance to pick up flammable, explosive or aggressive liquids (coolants and lubricants, gasoline, solvents, acids (pH < 5), alkalies (pH > 12.5), etc.).
•  Switch the appliance off immediately if foam or liquids escape from it.
•  Wear protective gloves when using the appliance to pick up hot materials up to a temperature of 60 °C.
• When working with mineral drilling slurry, wear protective clothing and avoid skin contact with the slurry (pH > 9: caustic).
•  Avoid contact with alkaline or acidic liquids. If contact accidentally occurs, rinse 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.
•  A Dust Class M appliance is suitable for picking up dry, non-flammable dusts, liquids, wood chips and hazardous dusts with an exposure limit value of ≧ 0.1 mg/m³. The appliance must be equipped with a suitable filter corresponding to the hazard classification of the dusts to be picked up.

Use and care of the appliance

•  Never leave the appliance unattended.
•  Protect the appliance from frost.
•  Clean the water level limiting device regularly with a brush, in accordance with the instructions, and check it for signs of damage.
•  When fitting the top section of the appliance, take care to avoid pinching your fingers or damaging the supply cord. This presents a risk of injury or damage.
•  Check the appliance and its accessories for any damage. Guards, safety devices and any slightly damaged parts must be checked carefully to ensure that they function faultlessly and as intended. Check that moving parts function faultlessly, without sticking, and that no parts are damaged. In order to ensure faultless operation of the appliance, all parts must be fitted correctly and must meet the necessary requirements.
•  Have the appliance serviced by a qualified repair person using only genuine Hilti spare parts. The safety of the appliance can thus be maintained.
•  Always unplug the supply cord from the power outlet when the appliance is not in use (during breaks), before cleaning and maintenance and before changing the filter or accessories. This preventive safety measure reduces the risk of starting the appliance accidentally.
•  Never use the power supply cord to pull the tool into a different working position. Do not run over the power supply cord with the tool.
•  Do not transport the appliance by crane.
