The 35-mm hose can be connected to optional accessories, including the Bosch VAC011 wand kit and the dust extraction hoods on various power tools and accessories, including those on Bosch router, planer, grinder, sander, jigsaw, and hammer/drill tools and accessories . The 3931A's hose port also accept many other vacuum hoses, including most 1-1/4" hoses, 11/2" hoses, 2-1/2" hoses and other Bosch hoses. (See Accessories, page 12 & 13) INSTALLING THE DUST BAG When dry-vacuuming such materials as dust from drywall, plaster, cement, soot, and flour, a dust bag should be inserted. Even when vacuuming other dry materials, using a dust bag extends the amount of time the unit operates at high performance and extends the amount of time it takes for the filter cartridge to become clogged. Using a dust bag also makes waste disposal much easier, eliminating the cloud of dust that is created when the canister contents are poured out, helping to protect you and the environment from exposure to the unwanted particles an debris. Notes: • VAC013 bags should not be used when wet vacuuming. • VAC022 heavy-duty wet/dry bags can be used when vacuuming wet materials. It is ideally suited for slurry-suction applications. • The filter cartridges must be installed, even when using a bag. To install the bag: 1. Unlock the canister latches and remove the control unit. -6-
