MACHINE CLEANING

Regularly clean the machine with a wet cloth.
CAUTION!
Do not clean the machine with high-pressure jets!
All bearings are protected against dust and do not require lubrication or maintenance.

BROOM ADJUSTMENT

Adjust the broom height when the bristles are worn or when their effi ciency is compromised.
1. Adjust the height of the main broom (9) with the two knobs (7). When turning them, each step on the marked numbers
amounts to a broom lowering.
Check that the two knobs (7) are on the same marked number. Otherwise there will be a difference in the longitudinal pressure
of the broom.
2. Adjust the height of the side brooms (6) with the knobs (5). When turning them counter-clockwise, each step amounts to a
broom lowering.
After the adjustment, push the machine to check that it moves smoothly, without diffi culty or resistance. Otherwise, repeat the
broom adjustment procedure.
If the brooms are too worn, replace them.

MAIN BROOM DISASSEMBLY/ASSEMBLY

CAUTION!
It is advisable to wear protective gloves when
replacing the brooms because there can be sharp
debris between the bristles.
NOTE
Only the rear main broom touches the fl oor and
wears.
Disassembly
1. Place the machine in a suitable place, with the bottom side
up.
2. Remove the screws (A, Fig. 1), then remove the supports
(B) with the main broom (C).
Pay attention to the driving belt (D) of the front main
broom.
3. Remove the driving belt (E, Fig. 2) from its housing on the
main broom (F).
4. Remove the main broom (F) and keep screws, supports
and bearings (G) for reassembly.
Assembly
5. Assemble the main broom in the reverse order of
disassembly, and note the following:
• Install the main broom with the bristles as shown in (H,
Fig. 1).
• Install the short driving belt by crossing it as shown (I,
Fig. 2).
• Pay attention to the proper position of the long driving
belt (D, Fig. 1).
• Turn the 2 knobs (7) on the position 1.
After installation, check the sweeper operation by testing the
rotation direction of the brooms (13).
