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. It also makes the disposal of dust easier.

Notes:

•Bags should not be used when wet- vacuuming.

•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.

2.Grasp a new dust bag at the flange. Push it over the bottom of the connection piece first and then over the catch on the top of the connection piece. Make sure that the full length of the dust bag faces against the inner wall of the canister.

3.Re-attach the control unit.

4.Lock the canister latches.

REMOVING THE DUST BAG

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

2.Pull the dust bag away from and off of the connection piece.

3.Close the opening in the dust bag by folding down the lid

4.Remove bag and dispose of properly.

REMOVING THE FILTER CARTRIDGES

1.First, clean the filters by setting the mode selector switch to the PULSE-CLEAN™ mode, which takes only 10 seconds.

2.To open the filter access compartment, use a coin to rotate the filter compartment lock by 1/4 turn in the direction of the arrow and push the lock in.

3.Lift up the top section of the control unit.

4.Grasp the filter cartridge by the fins, pull up and remove.

Replace a damaged filter cartridge immediately.

THOROUGH CLEANING OF THE

FILTER CARTRIDGES

If necessary, the filter cartridges can also be cleaned with a soft brush and can also be washed with water.

REPLACING THE FILTER CARTRIDGES

1.Insert new or cleaned filter cartridge and ensure firm seating.

2.Lower the top section down again.

3.With slight pressure from the top of the control unit, the filter compartment lock will snap back again.

CLEANING THE MOTOR

PROTECTION FILTERS

The motor protection filters are basically maintenance-free. Take out the motor protection filters from time to time and wash them. Allow them to dry thoroughly before reinserting.
