• Using a paper, fleece or wet/dry 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 to
become clogged.
• The plastic bags and fleece filter bags can
handle a heavier load without tearing than the
paper or wet/dry slurry bags.
• Fully enclosed Bosch fleece filter bags
provide the best option for reducing exposure
to dust (especially silica) when it is time to
remove the dust extractor control unit for bag
removal/disposal. The use of other Bosch
bags should be based on the application
being performed. For example: plastic bags
can be used for general jobsite clean up and
wet filter bags can be used for slurry.
Wet Vacuuming Notes:
• The wet/dry slurry bags can be used when
vacuuming wet materials. They are ideally
suited for slurry-suction applications.
• The fleece filter bags and paper bags should
not be used when wet vacuuming because
the water will cause the bag to come apart.
• The 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.
filter cleaning must be turned off when
using paper bags. The reversal of air during
filter cleaning may damage the paper bag.
INSTALLING A DUST BAG

3. Grasp a new dust bag at the flange. Push it
over the internal dust port first and then over
the raised ring. Make sure the entire flange is
seated in the recessed area of the internal dust
port. Make sure that the dust bag is not folded
over on itself and the full length of the bag
faces the front and bottom of the canister.
4. For plastic bags only – After the plastic bag
has been attached to the internal dust port,
wrap the upper edges of the plastic bag over
the entire perimeter of the rim at the top of
the canister. Make sure that the plastic bag
does not interfere with the canister latches.
5. Re-attach the control unit.
6. Lock the canister latches.
REMOVING THE DUST BAG
used, special caution is
needed when removing bags filled with
debris in order to reduce exposure to
airborne dust (especially silica dust from
concrete applications).
- Unlock the canister latches and remove the
control unit.
If a plastic bag is used:
1. Align the top of the plastic bag. Peel the
cover off the adhesive strip and fold over
onto the plastic bag to seal the top closed.
Save the cover for use in step 4.
2. Remove the plastic bag from the internal
dust port by pulling the bag towards the rear
of the canister.
3. Remove the bag from the canister and twist
the top of the bag.
4. Tie off the plastic bag below the port
opening using the cover that was just
removed from the bag's adhesive strip in
step 1 and dispose of properly.
5. Wipe dust extractor with a damp cloth to
clean the dust residue.
If a paper, fleece, or wet/dry slurry bag is
used:
1. Remove the bag from the internal dust port by
pulling the flange towards the rear of the
canister.
2. Pull the tab on the flange up until the opening
has been closed off by the paper cover.
3. Remove the bag from the canister and
dispose of properly.
4. Wipe dust extractor with a damp cloth to
clean the dust residue.
Note: Use extra caution when removing paper
bags. If overfilled, they can tear during removal
from the dust extractor.
