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.
• 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.
