1 In order to avoid having the paper bag tear while the machine is running, it is advisable to open the bag before installing it in the machine. This can be done by gently pulling open the pleats (a) that are on each side of the bag, so that the cross section of the bag is almost square.
2 To avoid tearing the bag at the paper bag inlet (b), gently push in and open the perforations (c) in the paper of the bag, just inside the hole of the rubber bag seal (d).
3 Install the opened bag in the lower container so that the paper bag inlet (b) is facing downward in the bottom of the container. Then carefully grasp the cardboard tabs (e) on each side of the bag seal with both hands and slide the bag seal over the inlet tube (g). Start from the bottom of the inlet tube and gently pull the seal over the inlet tube with a slight rocking or twisting motion, pulling as far up as the ribs on the inlet tube.
4 After the bag seal touches the ribs of the inlet tube, fold back the sewn (h) seam so it does not interfere with closing the container. Expand the sides of the bag in the container so that the top of the bag is even with the sides of the container.
Dust bag systems

Disposable container
For hazardous dust, a disposable container is available. When the container is full, it is sealed with a lid and a locking ring making the container safe to dispose.
14 Exhaust filter All models
Exhaust filters are used when absolutely clean exhaust air is necessary. The exhaust filter is mounted on to the motor in place of the diffuser. The exhaust filter is easily fitted and the filter element is replaceable. A special handle and instructions for use are delivered together with the exhaust filter.

Mounting
Remove the diffuser and sound absorber (see page 2)
1 Place the blowing adaptor 115620 on the motor. Each one is kept in place by handle of the motor.
2 Fit the blowing attachment into the motor blowing adaptors.
3 Before connecting a hose make sure that it is clean - place its open end in the container inlet for a moment with the motors running and shake it.
16 Sound suppressor All models
The sound level of the vacuum cleaner is low. If an even lower sound level is required or desired, a sound suppressor can be fitted on to the motor.
The sound suppressor are mounted in place of the diffuser (see page 4). The sound suppressor reduces the motor noise by another 4 dB corresponding to approximately 37%.
It is only possible at any one time to fit either exhaust filters or blowing attachment or sound suppressors.
17 Motor protection filter
For special filtration tasks, the lower part of the motor can be fitted with a filter. This filter must be replaced on a regular basis.

To disconnect, reverse above procedure.
Adjustment of rubber blades
4The distance of the rubber blades from the floor should be about 1 mm, and the adjustment is made by means of the two fingerscrews.
5During idle periods or during transportation, the nozzle should be raised from the floor by placing the nozzle brace in the second notch on hinge level.
6As an alternative a brush set consisting of floor brush strips is available.
Maintenance
Always keep the cleaner in a dry place. The bearings in the motor are pregreased and designed for continuous heavy work. Depending on the number of running hours the dust filter should be replaced. For details of service or maintenance please contact Nilfiskdirectly.
