SP6732-1 4 gallon ES 4/18/12 2:14 PM Page 7 Operation (continued) Vacuuming Dry Materials 1. The filter must always be in correct position at all times to avoid leaks and possible damage to Vac. 2. When using your Vac to pick up very fine dust, it will be necessary for you to empty the drum and clean the filter at more frequent intervals to maintain peak Vac performance. NOTE: A dry filter is necessary to pick up dry material. If you use your Vac to pick up dust when the filter is wet, the filter will clog quickly and be very difficult to clean. Vacuuming Liquids 1. When picking up small amounts of liquid the filter may be left in place. 2. When picking up large amounts of liquid we recommend that the filter be removed. If the filter is not removed, it will become saturated and misting may appear in the exhaust. Emptying the Drum 1. To remove the lid to empty contents of the dust drum, simply lift the two drum latches on the side of the Vac and lift the power head up and off the dust drum and set to the side. Power Head Dust Drum Drum Latch 2. Lay the power head upside down on a clean dry area while emptying the drum or changing the filter. 3. Dump the drum contents into the proper waste disposal container. ! WARNING: Do not operate without filter cage and float, as they prevent liquid from entering the impeller and damaging the motor. 3. When the liquid in the drum reaches a predetermined level, the float mechanism will rise automatically to cut off airflow. You will know that the float has risen because Vac airflow ceases and the motor noise will become higher in pitch, due to increased motor speed. When this happens, turn off the Vac, unplug the power cord, and empty the drum. 4. After using the Vac to pick up liquids, the filter must be dried to avoid possible mildew and damage to the filter. Blowing Feature Your Wet/Dry Vac has the capability to be used as a blower for yard work, patio cleanup and workshop applications to blow sawdust and other debris. ! WARNING: Always wear safety eyewear complying with ANSI Z87.1 (or in Canada, CSA Z94.3) before using as a blower. ! WARNING: To reduce the risk of injury to bystanders, keep them clear of blowing debris. ! CAUTION: Wear a dust mask if blowing creates dust which might be inhaled. ! CAUTION: To reduce the risk of hearing damage, wear ear protectors when using the Vac/blower for extended time or in a noisy area. 7
