FUELING MAINTENANCE AND LUBRICA TION

Danger

NOT carry extra fuel containers the cab. Fuel containers, full empty , may leak, explode give added fuel a fire. Failure follow this precaution may lead serious personal injury death.

Danger

NOT smoke while fueling the vehicle. The glow from the cigar/cigarette can ignite the diesel fuel, causing explosion resulting serious personal injury death.

Danger

not remove the fuel tank cap near open flame. Diesel fuel vapors are combustible and can cause explosion fire, resulting severe personal injury death.

Caution

Diesel - power engines for heavy - duty trucks built after January 2007 e designed operate only with Ultra Low Sulfur Diesel (ULSD) fuel. Impr oper fuel use will r educe the efficiency and durability engines, permanently damage advanced emissions contr systems, r educe fuel economy and possibly event the vehicles running all. Manufactur warranties will voided impr oper fuel use. Additionally , burning Low Sulfur Diesel fuel (instead ULSD fuel) 2007 and later model year diesel - power cars, trucks and buses illegal and punishable with civil penalties.

Caution

Ultra Low Sulfur Diesel (ULSD) fuel with a maximum sulfur content ppm must used der meet Eur engine emission r equir Using otherwise appr oved diesel fuels with a maximum sulfur content eater than 500 ppm may shorten engine life and void the engine warranty

Air always present inside the fuel entering mainly through the tank With the air being heated and condensation formed and water mixed the T o avoid condensation when the vehicle parked for longer fill the tanks 95% capacity not fill more than the fuel needs have room for expansion during the heat the day
