CENTRAL BRUSH ADJUSTMENTS:
If the machine starts cleaning in a faulty manner or leaves dirt around, it will have to be adjusted and lowered as followed:
- Position lever Part. 1 Fig. 16 so that the central brush is raised.
- Loosen screw Part. 2 Fig. 16.
- Lower the adjuster Part. 3 Fig. 16 by 3/4 mm or by the desired distance.
- Secure the adjuster by tightening screw Part. 2 Fig. 16
- Position lever Part. 1 fig. 16 above the adjuster Part. 3 fig. 16.
- The central brush can be adjusted until the adjuster Part. 3 fig. 16 reaches the end of stroke; after this, the brush must be replaced.
IMPORTANT: To ensure the central brush is correctly adjusted, measure its "Track" as follows:
- After adjustments, start the machine up and, and without moving either forwards or backwards, leave it standing in the same place
for at least 10 / 15 sec. with the central brush lowered.
- Turn off the engine, raise the central brush and move the machine forwards manually until the mark left on the floor by the rotation
of central brush is visible, as shown in Fig. 17.
ADJUSTMENT OF THE SIDE BRUSHES :
When the side brushes Part. 1 Fig. 18 are no longer able to convey dirt to the central brush, the height of the side brushes will have to be
adjusted as follows:
- Keeping the side brushes raised, turn anticlockwise the register Part. 3 fig. 8.
COLLECTION BIN:
Every 50 / 60 working hours or whenever necessary, wash the collection bin Part. 1 Fig. 7 using warm water and, if necessary, common
detergent. This will prevent any bacteria build-up (wear rubber gloves).
