[. . . ] When dust removers are used, the rate at which air is exchanged in the room must be adequate if the exhaust air from the vacuum cleaner is blown into the room (please observe regulations valid in your country). Before starting work, the operating staff must be informed on ­ use of the vacuum cleaner ­ risks associated with the material to be picked up ­ safe disposal of the picked up material. Precautions and safety regulations when using the vacuum cleaner Before start-up Inspect power cord regularly to detect signs of damage, e. If the power cord is damaged, it must be replaced by MakitaService or an electrician to avoid danger before use of the vacuum cleaner is continued. [. . . ] A dust test must be performed at least once every year by Makita service or a trained person. This test includes, for example, whether there is damage to the filter, the vacuum cleaner is sealed to the air and the control equipment works properly. Use only the brushes supplied with the vacuum cleaner or specified in the operating manual. Use only original Makita accessories and spare parts (see section 9. When used properly, the industrial vacuum cleaners described in these instructions are suita- See fold-out page at front of these operating instructions. 1 Dirt tank 2 Retaining clamp 3 Appliance switch with suction power control 4 Handle with cable hook 5 Operating knob for filter cleaning 6 Appliance socket 7 Inlet fitting 8 Grip to empty tank 9 Mounting for accessories The mains plug should not yet be inserted into a socket. Fit the upper section of the cleaner (do not damage the filter bag) and close the retaining clamps. The operating voltage shown on the rating plate must correspond to the voltage of the mains power supply. Insert the power cord into a properly installed and fused socket with earthing contact. To comply with regulations, only approved dust producing tools should be connected. The maximum power consumption of the connected power tool is stated in section 9. The vacuum cleaner motor starts when the connected power tool is switched on. Before switching the switch to position "auto", ensure that the power tool connected to the appliance socket is switched off. When the power tool is switched off, the vacuum cleaner continues to run for a short moment so that any dust in the suction hose is conveyed to the filter bag. The motor speed and the suction power can be varied with the suction power control. This allows precise adaptation of the suction power for different cleaning tasks. If used correctly, additional accessories, suction nozzles and suction hoses can enhance the cleaning action and reduce the cleaning effort. Effective cleaning is achieved if you follow just a few guidelines in combination with your own practical experience in special fields. Before picking up dry substances, always ensure that a filter bag is inserted in the tank (see section 9. A damp filter element clogs more quickly when dry substances are picked up. [. . . ] If it can not be started again, contact the Makita service department. Check that the power tool works or that the plug is inserted correctly. Fault Reduced suction power Cause > Suction power selected with suction power control is to low. In accordance with European guideline 2002/96/EG on Waste Electrical and Electronic Equipment all used up electrical appliances must be collected separately and supplied to a environmentalfair recycling.
