When unpacking, make sure that all of the standard equipment is present and that there is no transportation damage.

Before preforming any work on the machine itself, disconnect the power plug.

ATTACHING THE VACUUM HOSE

Connect the 35-mm vacuum hose (standard equipment) onto the canister’s hose port by sliding the wider end of the hose onto the port then turning it to the right slightly to lock it in place.

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 canister’s hose port also accept many other vacuum hoses, including most 1-1/4” hoses, 1-1/2” hoses, 2-1/2” hoses and other Bosch hoses. (See Accessories, page 12 & 13)

DUST COLLECTION OPTIONS

There are four dust collection options: plastic bag, paper bag, slurry bag or no bag.

The filter cartridges must be installed whether or not any of the bags are used.

Dry Vacuuming Notes:

When dry-vacuuming such materials as dust from drywall, plaster, cement, soot, and flour, a dust bag should be inserted.

Using a paper or slurry 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.

A plastic bag can handle a heavier load without tearing than the paper or slurry bags.

Using any of the three types of Bosch dust bags also makes waste disposal much easier, eliminating the cloud of dust that is created when canister contents are simply poured out, helping to protect you and the environment from exposure to the unwanted particles and debris.

Wet Vacuuming Notes:

The VAC022 heavy-duty wet/dry bags can be used when vacuuming wet materials. They are ideally suited for slurry-suction applications.

The VAC013 paper bags should not be used when wet vacuuming because the water will cause the bag to come apart.

The VAC023 plastic bags should not be used when wet vacuuming because the bag may tear when removed if it is fully loaded with liquid.

See WET VACUUMING section for more information.

INSTALLING A DUST BAG

1.Unlock the canister latches and remove the control unit.

2.Properly position the rotary air valve for the dust collection to be used, according to (Fig. 3).

3.Grasp a new dust bag at the flange. Push it over the bottom of the internal port hose first and then over the catch on the top of the internal port hose. Make sure that the full length of the dust bag faces against the inner wall of the canister (Fig. 4).

4.Plastic bag only – If plastic bag is used, wrap the upper edge of the plastic bag over all four sides of the rim at the top of the
