However, in this situation, the Power Tool Activation feature cannot be used. Switching the Vacuum Cleaner ON 1. Make sure the power tool is switched off, and then plug it in. 2. Turn the mode selector switch to POWER TOOL ACTIVATION position. 3. When the power tool is switched on, the power tool automatically switches on the vacuum cleaner. Switching The Vacuum Cleaner OFF 1. When the power tool is switched off, the vacuum cleaner is switched off. In order to empty the hose, the vacuum cleaner switches off after a 6 second delay. PULSE-CLEAN™ FILTER CLEANING The vacuum cleaner is equipped with the electromagnetic PULSE-CLEAN™ filter cartridge cleaning system, which in 10 seconds allows the unit to self-remove dust that is adhering to the filter cartridges. Before using the PULSE-CLEAN™ mode, we suggest to advise those in hearing range about the sound of this feature. PULSE-CLEAN™ MODE (when no power tool is plugged in) 1. Turn vacuum cleaner dial to PULSECLEAN™ setting. 2. The filter cleaning process will be automatically completed within about 10 seconds. 3. After PULSE-CLEAN™ cycle completes itself, the vacuum cleaner will become idle. 4. Switch the vacuum cleaner to the OFF or ON position, as desired. See PULSE-CLEAN™ notes below. PULSE-CLEAN™ MODE COMBINED WITH POWER TOOL ACTIVATION The PULSE-CLEAN™ system can also be used when a power tool is connected and used with the "POWER TOOL ACTIVATION MODE". This is very handy when the location of vacuum cleaner is separated from the connected power tool, such as when the tool is being used up on a scaffold. 1. Make sure the power tool is switched off, and then plug it in. 2. Plug the power tool into the vacuum cleaner's power tool outlet. 3. Turn the vacuum cleaner dial to PULSECLEAN™ setting. 4. The vacuum cleaner goes into the PULSECLEAN™ mode for 10 seconds. 5. After PULSE-CLEAN™ mode is completed, switch on the power tool, and the vacuum cleaner will operate until the power tool is switched off or disconnected from the vacuum cleaner. 6. At the time the tool is switched off, the vacuum cleaner will automatically determine if the filter needs to be cleaned. If it determines that cleaning is necessary, the PULSE-CLEAN™ system automatically activates, the cleaning process will be completed within about 10 seconds. 7. After PULSE-CLEAN™ cycle completes itself, the vacuum cleaner will become idle. 8. Switch the vacuum cleaner OFF, or to continue working, switch the power tool on again. 9. If power tool is switched on before the PULSE-CLEAN™ cycle is complete, PULSE-CLEAN™ automatically stops and vacuum cleaner starts to vacuum. PULSE-CLEAN™ Notes: • The sound of the PULSE-CLEAN™ system may surprise those near the work area. Before using PULSE-CLEAN™, alert those in the vicinity of the vacuum cleaner of this feature and the associated sound it makes. • Do not keep power tool plugged into vacuum during normal vacuum cleaning mode, because any connected power tool will receive power when vacuum cleaner is moved from normal vacuum cleaning mode to PULSE-CLEAN mode. • The PULSE-CLEAN™ system must be activated when the suction power decreases to the point of being insufficient. • The PULSE-CLEAN™ system should be activated regularly to keep the filter cartridges clean. The proper frequency for activating the PULSE-CLEAN™ system depends on the type and amount of dust. With regular usage, the maximum vacuuming performance is maintained longer. -9-
