[. . . ] The relevant additional instructions are supplied together with the vacuum cleaner. Vacuum cleaners for dust harmful to health are classified according to the following dust classification: L (low risk) suitable for separating dust with an exposure limit value of over 1 mg/m3, depending on the volume occupied; M (medium risk) for separating dust with an exposure limit value of over 0. 1 mg/m3, depending on the volume occupied; H (high risk) for separating all dust with an exposure limit value lower than 0. Indicative values of performance: version for dust harmful to health (Classes L, M, H): L: retains at least 99. [. . . ] Wait before restarting the vacuum cleaner, to allow the dust to settle. Check the flow rate: When the vacuum cleaner is operating, the pointer of the vacuum gauge (2) must remain in the green zone (OK) (3) to ensure that the speed of the intake air does not drop below the safety value of 20 m/sec; If the pointer is in the red zone (STOP) (1) it means that the speed of the air in the vacuum hose is less than 20 m/s and that the vacuum cleaner is not operating in safety conditions. After cleaning or replacing the filters, the vacuum gauge pointer must return to the green zone and the sound (M and H versions) must stop. When the vacuum hose is closed, the pointer of the vacuum gauge must switch from the green zone (OK) (3) to the red zone (STOP) (1) and the horn on M and H versions must emit a pulsing sound. Before emptying the container it is advisable to clean the filter (see "Shaking the main filter" paragraph). Turn off the vacuum cleaner and remove the plug from the socket. Wash the container with clean water if aggressive substances have been vacuumed. Store the vacuum cleaner in a dry place, out of reach of unauthorized people. Shut the inlet with the appropriate plug when the vacuum cleaner is transported or not being used (particularly in the case of M, H versions) (1, Fig. How to replace the ABS safety container: Place the vacuum hose in a safe, dust-free place. Close the safety container with the supplied cover and remove it from the dust container (1), fit an empty container in its place. Start the motor again to prevent dust from being blown about. Make sure that the gasket is in perfect condition and correctly positioned. Switch off the motor, fit an empty container in place and fasten it in position. Replacement of the safety bag for class H vacuum cleaners (Fig. 12) Remove and put the vacuum hose in a safe and dustfree place. Close the inlet by using the relevant cap (1). Remove the bag making sure that the union tubular element (3) is kept connected to the inlet. Remove the union element from the dust container inlet. Insert a new safety bag making sure that the bag inlet is sealed. To allow the user to carry out the maintenance operations, the vacuum cleaner must be disassembled, cleaned and overhauled as far as is reasonably possible, without causing hazards for the maintenance staff or other people. The suitable precautions include decontamination before disassembling the vacuum cleaner, adequate filtered ventilation of the exhaust air from the room in which it is disassembled, cleaning of the maintenance area and suitable personal protection. [. . . ] Cover the filter (4) with a plastic bag. Seal the plastic bag hermetically and insert a new filter unit which complies with the laws in force. Dispose of the old filter according to the laws in force. [ NOTE ] If there is only a dust deposit on the separator (4, Fig. [. . . ]
