Every 40 / 70 working hours or whenever necessary, check the dust filters Part. 1 Fig. 14. Remove them from
housing, loosen the filter-pressing blocks Part. 2 Fig. 14 and clean the filters by, first of all, banging them
on the floor (not violently), keeping the perforated side towards the floor. For more thorough cleaning, use a
compressed-air gun and blow from outside towards the inside, as shown in figure 14. When refitting the filters,
always remember to replace the black seal Part. 3 Fig. 14 on the bottom of the filter.
Make sure that the filters are always in good condition and, whenever necessary, replace them.
DUST SEALS:
Every 40 / 70 working hours, check the condition of the dust seals Part. 1 (movable) and Part. 2 (3 fixed seals)
Fig. 15 surrounding the central brush Part. 2 Fig. 4. Whenever necessary, replace these.
IMPORTANT: By replacing the seals make sure the side seals (the shortest one on the right and on
the left. in total 2) are raised off the ground of about 2 mm.
CENTRAL BRUSH:
Part. 2 Fig. 4. Every 50 / 80 working hours, or whenever necessary, check the condition of the central brush,
especially if you have picked up pieces of string, wire, etc.
To remove such items from the brush:
- Remove the bin Part. 2 Fig. 7 .
- Kneel down and inspect the central brush under the machine. Wearing gloves and a face mask to
protect the airways, remove any pieces of string or wire wrapped around the central brush. The 4 hooks
(eyebolts) provided can also be used to raise the machine (see Fig. 1) and perform this operation. Take
care not to stand underneath the machine.
