GENERAL SAFETY RULES
Carefully follow the rules described below to avoid injury to the operator and damage to the machine.
Carefully read the labels on the machine, do not cover them for any reason and replace them immediately if they
become worn or damaged.
- The machine storage temperature range should be between 32˚F and 104˚F
- The machine working temperature is from +32°F to +104°F
- Humidity range should be between 30% and 95%.
- Do not use the machine in an explosive atmosphere environment
- Do not use the machine as a transport vehicle.
- Do not allow the brushes to operate while the machine is stationary to avoid damaging the floor.
- In case of fire, use a powder extinguisher.
- Do not bump into shelves or scaffolding where there is a risk of falling objects.
- Adjust the operating speed to the floor conditions.
- Do not exceed the declared slope limit to avoid an unstable condition.
- When the machine is parked, remove the key and engage the parking brake.
- When machine-operating malfunction occur, make sure that they are not caused by a lack of routine maintenance.
If not, request assistance from the service centre.
- If parts must be replaced, request ORIGINAL spare parts from a dealer or Authorised Retailer.
- Before any maintenance operations, disconnect the electric power supply from the batteries.
- Do not remove guards which require the use of tools to be disassembled.
- Do not wash the machine with pressurised water, or with corrosive substances.
- A service centre should inspect the machine every 200 hours of operation.
- The machine must be disposed of properly, because of the presence of toxic-harmful materials (battery acid, oil,
etc.) which are subject to standards that require disposal in special centres.
- The machine will not generate damaging vibration.
SAFETY- ACCIDENT PREVENTION
No accident prevention program is effective without the complete co-operation of the person directly responsible for
operating the machine. Most of the accidents that may occur in a company, on the job or during transfers are caused
by not-observing fundamental safety rules. A careful and cautious user is the best guarantee against accidents and
is more effective than any type of prevention program. While using the machine pay attention to your surroundings
and people nearby, especially to children.
