MACHINE OPERATION

1. Avoid stopping for a long time with the machine in the same position and the brooms turning: this could create unwanted
marks on the fl oor.
2. To collect light and bulky waste materials, lift the front skirt by pulling the lever (27); take into consideration that the machine
vacuum capability is reduced when the front skirt is lifted.
3. For machine proper operation, the dust fi lter must be as clean as possible. To clean the fi lter while sweeping, turn on the fi lter
shaker by proceeding as follows and according to the type of fi lter shaker installed:
• Manual fi lter shaker: Turn the ignition key to "0". Pull the handle (20) outward to the end of stroke, then suddenly release
it; the inner return spring thus strikes the dust fi lter frame and shakes it. Repeat this procedure several times. To start
sweeping again, turn the ignition key to "I".
• Electrical fi lter shaker (optional): Press the fi lter shaker switch (67) for a few seconds. During this procedure the main
motor and all functions are automatically cut-off.
NOTE
Repeat the fi lter shaking procedure at least every 10 minutes. This interval can change depending on the dustiness of
the area to be cleaned.
NOTE
When the dust fi lter is clogged and/or the debris container is full, the machine cannot collect dust and debris anymore.
CAUTION!
Do not work on wet fl oors to prevent the dust fi lter from being damaged.
4. The debris container (17) should be emptied after each working cycle and whenever it is full.
