On consignment of the machine

When the machine is delivered to the customer, an immediate check must be performed to ensure all the material mentioned in the shipping documents has been received, in addition to verifying that the machine has not been damaged during transportation. If this is the case, the carrier must ascertain the extent of the damage at once, informing our customer service office. It is only by prompt action of this type that the missing material can be obtained, and compensation for damage successfully claimed.

Serial number plate

Introductory comment

Even the best machines will only work well if used correctly and kept in good working order. We therefore suggest you read this instruction booklet carefully and read it again whenever difficulties arise while using the machine. If necessary, remember that our assistance service (organised in collaboration with our dealers) is always available for advice or direct intervention.

Identification data

For technical assistance or to request replacement parts, always give the model, the version and serial number written on the serial number plate.

Technical description

The CS90 are ride-on sweeping machines, powered electrically (with traction batteries) or with an internal combustion (endothermic) engine, for the cleaning of both internal and external surfaces with tiled, concrete or asphalt floors. The machine must operate on dry surfaces, and if necessary can also work on wet surfaces making sure the vacuum action is not active. The machine features a central brush for the collection of brushed up material, a side brush for cleaning edges and corners, a vacuum system with filter to avoid raising dust, and a debris hopper that can be manually removed by means of a mechanical leverage.

Intended use

The sweeping machine is designed to clean both inside and outside surfaces with tiled, concrete and asphalt floors, for professional use in industrial, commercial and public places. The machine is only suitable for use in closed (or at least covered) places. The machine is not suitable for use in the rain, or under water jets. It is FORBIDDEN to use the machine for picking up dangerous dusts or inflammable liquids within places with a potentially explosive atmosphere. In addition, it is not suitable as a means of transport for people or objects.

GENERAL SAFETY REGULATIONS

The regulations below must be carefully followed in order to avoid harm to the operator and damage to the machine. WARNING:

 Read the labels on the machine carefully. Do not cover them for any reason and replace them immediately if they become damaged.  The machine must be used exclusively by authorised and trained personnel.  The machine is designed for dry use only.  Do not use the machine on surfaces with an inclination greater than the one shown on the plate.  The machine is not suitable for cleaning rough or uneven floors. Do not use the machine on slopes.  In the event of danger immediately use the handle on the battery connector (battery versions), or else turn the battery cut-off switch (Diesel - Bifuel versions).  For all maintenance interventions, switch off the machine and disconnect the battery connector and/or the power supply cable.  Children must be supervised to ensure they do not play with the device.  During the working of the machine, pay attention to other people and especially to children.  Only use the brushes supplied with the machine, or those specified in the "CHOOSING AND USING THE BRUSHES" paragraph of the instruction

manual. The use of other brushes could compromise safety levels.

WARNING:  The machine is not suitable for use by children and persons with reduced physical, mental and sensory capabilities, or people who lack experience and

knowledge.

 The machine must not be used or stored outdoors, in damp conditions or directly exposed to rain.  The storage temperature must be between -25C and +55C; do not store outdoors in damp conditions.  Conditions of use: room temperature between 0°C and 40°C with relative humidity between 30 and 95%.  The socket for the battery charger cable must have a prescribed earth connection.  Adapt the speed to the adhesion conditions.  Do not use the machine as a means of transport.  The machine does not cause harmful vibrations.  Do not use the machine in an explosive atmosphere.  Do not use the device to collect dangerous powders.  The machine is not suitable for cleaning carpets.  Do not place any liquid containers on the machine.  Avoid working with the brushes when the machine is standing still, so as not to damage the floor.  In the event of a fire, use a powder extinguisher. Do not use water.  Do not knock against shelving or scaffolding, where there is a danger of falling objects. The operator must always be equipped with the appropriate

safety devices (gloves, shoes, helmet, goggles, etc.).



If the machine does not work properly, check this is not caused by failure to carry out routine maintenance. Otherwise, ask for intervention of the authorised technical assistance centre.

 If you need to replace any components, request the ORIGINAL spare parts from an Authorised dealer and/or Retailer.  Restore all electrical connections after any maintenance interventions.  Before using the machine, check that all the hatches and covers are positioned as shown in this Use and Maintenance Manual.  Do not remove any protection devices which require the use of tools in order to be removed.  Do not wash the machine with direct water jets or with pressurised water, nor with corrosive substances.  Have the machine checked by an authorised technical assistance centre every year.  When disposing of consumable materials, observe the laws and regulations in force.  When your machine has reached the end of its long working life, dispose of the materials it contains (especially oils, batteries and electronic

components) in an appropriate manner, and bearing in mind that the machine itself was constructed using 100% recyclable materials.

 The batteries must be removed from the machine before its disposal. The batteries must be disposed of in a safe manner, fully observing the laws and

regulations in force.

 Keep children and animals away from the powered motor, as it heats up and may cause burns and injuries (both directly and via the machines which it

moves).

 Learn how to switch the combustion engine off quickly, and how to use all the controls. (versions with combustion engine)  When the engine is on, do not bring flammable objects near, for example gasoline, matches, etc. (versions with combustion engine)  Top up the fuel in a well-ventilated area, with the motor switched off; The fuel is highly inflammable and may explode.(versions with combustion engine)  Do not completely fill the fuel tank. Check the cap is firmly closed. (versions with combustion engine)  If any fuel is spilt, clean the area thoroughly and allow the vapours to disperse before switching on the motor. (versions with combustion engine)  Do not smoke or take any unprotected flames in the area where the motor is filled with fuel, or where the gasoline is stored. (versions with combustion engine)  The exhaust gases contain carbon monoxide - an odourless, colourless, but highly poisonous gas. Avoid inhalation. Do not switch the motor on in a

closed garage or in a room without windows (versions with combustion engine)
