2.Loosen the clamp, and remove the dust can.

3.Remove the thumb nut, on the center retaining rod, to remove the filter cartridge.

•Try vacuum-cleaning a soiled filter first. Vacuuming removes most large particles and surface contaminants, and may suffice for the first time you clean a filter.

•Use a commercial-duty (recommended) or household vacuum

cleaner. Vacuum the filter from the air intake (dirty) side only.
