This may negatively affect the electrical safety of the appliance. Always keep the grip surfaces of the appliance free from oil and grease. Do not use cleaning agents which contain silicone. For vacuum cleaners of the class M, please note: The appliance must be handled for cleaning and maintenance in a way that avoids exposing maintenance personnel and other persons to any hazards. Use filtered forced ventilation. Wear personal protective equipment. Clean the maintenance area in a way that prevents hazardous substances escaping into the surrounding environment. Vacuum off the outer surfaces of the appliance, wipe it clean or seal it in suitable container or material before removing it from an area contaminated with hazardous substances. This will help to avoid distribution of the hazardous dust deposited on it. When maintenance or repairs are carried out, all con- taminated parts which cannot be satisfactorily cleaned must be packed in impermeable bags and disposed of in compliance with the applicable disposal regulations. A vacuum cleaner of the class M must be subjected to a technical inspection by Hilti Service or a trained person at least once a year to check, for example, for damage to the filter, air leakage, and to ensure correct operation of controlling devices.

8.5 Care of the Li-ion battery

Avoid ingress of moisture. Charge the battery fully before using it for the first time. In order to achieve maximum battery life, stop discharging the battery as soon as a significant drop in performance is noticed. NOTE If use of the tool continues, further battery discharge will be stopped automatically before the battery cells suffer damage. The tool switches itself off. Charge the battery with the Hilti charger approved for use with Li-ion batteries. NOTE - A conditioning charge (as is required with NiCd batter- ies) is not necessary. - Interruption of the charging procedure has no negative effect on battery life. - Charging can be started at any time with no negative effect on battery life. There is no memory effect (as with NiCd batteries). - For best results, batteries should be stored fully charged in a cool dry place. Storing the battery in places subject to high ambient temperatures (e.g. at a window) has an adverse effect on battery life and increases the rate of self-discharge. - If the battery no longer reaches full charge, it may have lost capacity due to aging or overstressing. It is possible to continue working with a battery in this condition but it should be replaced in good time.

WARNING Repairs to the electrical section of the appliance may be carried out only by trained electrical specialists. Check all external parts of the appliance for damage at regular intervals and check that all controls operate faultlessly. Do not operate the appliance if parts are damaged or when the controls do not function faultlessly. If necessary, the appliance should be repaired by Hilti Service.

8.7 Checking the appliance after care and

maintenance After carrying out cleaning and maintenance, check that the vacuum cleaner has been correctly reassembled and that it operates faultlessly. Test each of the functions. 9 Troubleshooting DANGER In the event of a malfunction, disconnect the supply cord plug from the power outlet. Remove any batteries from the battery compartment.

Batteries may explode if damaged or exposed to very high temperatures, causing poisoning, burns, acid burns or environmental pollution. Careless disposal may permit unauthorized and improper use of the equipment. This may result in serious personal injury, injury to third parties and pollution of the environment. CAUTION Dispose of defective batteries without delay. Keep them out of reach of children. Do not attempt to open or dismantle batteries and do not dispose of them by incineration. CAUTION Dispose of the batteries in accordance with national regulations or return them to Hilti.

Printed: 24.03.2014 | Doc-Nr: PUB / 5140202 / 000 / 03 Printed: 28.03.2019 | Doc-Nr: PUB / 5140202 / 000 / 04Most of the materials from which Hilti power tools or appliances are manufactured can be recycled. The materials must be correctly separated before they can be recycled. In many countries, Hilti has already made arrangements for taking back your old power tools or appliances for recycling. Ask Hilti customer service or your Hilti representative for further information. For EC countries only Do not dispose of electrical appliances together with household waste. In observance of the European Directive on waste electrical and electronic equipment and its implement- ation in accordance with national law, electrical appliances and batteries that have reached the end of their life must be collected separately and returned to an environmentally compatible recycling facility. Disposing of drilling slurry Disposing of drilling slurry directly into rivers, lakes or the sewerage system without suitable pretreatment presents environmental problems. Ask the local public authorities for information about current regulations. We recommend the following pretreatment:

1. Collect the drilling slurry (for example, using a wet-type vacuum cleaner).

2. Allow the drilling slurry to settle and dispose of the solid material at a construction waste disposal site (the

addition of a flocculent may accelerate the separation process).

3. The remaining water (alkaline, pH value greater than 7) must be neutralized by the addition of an acidic neutralizing

agent or diluted with a large volume of water before it is allowed to flow into the sewerage system. Disposal of drilling dust The drilling dust collected must be disposed of in accordance with the applicable national regulations. 11 Manufacturer’s warranty Please contact your local Hilti representative if you have questions about the warranty conditions. 12 EC declaration of conformity (original) Designation: Wet / dry vacuum cleaner Type: VC 20-U‑Y/VC 20- UM‑Y/VC 40-U‑Y/VC 40- UM‑Y Generation: 01 Year of design: 2012 We declare, on our sole responsibility, that this product complies with the following directiv es and standards: 2006/42/EG, 2014/30/EU, 2011/65/EU, EN 60335‑1, EN 60335‑2‑29, EN 60335‑2‑69, EN ISO 12100.
