Fuel

Environment

The fuel to be used must comply with the D975 norm of the American Soc iety for T esting and Ma terials (ASTM).

Before c arrying o ut an y m aintenance op eration o n this machine and before throwing away the liquids or lubricants us ed, al ways thi nk of the env ironment. Never throw oil or liquids on the ground and never put them in leaking containers.

Use type N°2 fuel, use of other fuels can cause a loss of engine power and excessive fuel consumption. In cold weather, i t i s pr ovisionally accepted th at a mixture of N°1 et N°2 fuels be used. Contact your fuel supplier. If the te mperature dr ops bel ow the freezing point of the fuel (point where paraffin appears), paraffin crystals i n th e fue l wi ll cause los s of en gine po wer or starting trouble. IMPORTANT: In cold weather, fill up the reservoir with fuel after each workday, in order to avoid the formation of condensation.

Storing fuel

Consult yo ur local ce ntre for ecological r ecycling for information on th e ap propriate m ethod for di sposing off these substances.

Plastic and resin parts When c leaning pl astic par ts, the console, th e ins trument pa nel, the ind icators etc ... a void u sing petrol, kerosene, pai nt s olvents etc ... Us e o nly wa ter, s oap and a soft cloth. The u se o f petr ol, k erosene, pai nt s olvents etc... causes discoloration, cracks or deformation of these parts.

Prolonged storage of fuel promotes the accumulation of foreign bodies or condensed moisture in the storage tank. Man y en gine fai lures ar e c aused by th e presence of water in fuel. The storage tank must be placed outside and the fuel should be ma intained at as lo w a temperature as possible. Dr ain the co ndensed moi sture at r egular intervals.

Antifreeze/anticorrosive Use the antifreeze in all seasons to pr otect the c oolant system fr om c orrosion and to avoid an y r isk of freezing. In en vironments wi th a te mperature g reater th an 33°F (-36°C), us e a 50 % mi xture of an tifreeze in a n ethylene glycol base. In environments with a temper ature less t han - 33°F ( 36°C), it is r ecommended that you us e a 40% water and 60% antifreeze mixture.
