Do not use Number 2-D fuel at temperatures below -
7°C (20°F) . The cold temperatures will cause Number
2-D fuel to thicken, which may keep the engine from
running . (If this happens, contact your Buhler Versatile
dealer .)
For the best fuel economy, use Number 2-D whenever
the temperature will permit .
To be sure a fuel meets the required properties,
enlist the aid of a reputable fuel oil supplier . The
responsibility for clean fuel lies with the fuel supplier
as well as the fuel user .
Adding Diesel Fuel
Fuel can be added to either tank . The two tanks are
connected via a crossover tube . Total usable capacity
of the two tanks is 330 U .S . gallons (249 L) .
Each fuel tank has a vent tube located on the rear
corner of the tank . The tube runs vertically inside the
cab frame and requires no maintenance .

FILL TO BOTTOM OF FILLER NECK OR USE THE
ELECTRONIC INSTRUMENT CONTROL SYSTEM TO
AID IN REFUELING. WHEN THE ALARM SOUNDS A
SOLID TONE, THE TANK IS FULL. ALLOW ROOM FOR
EXPANSION. FUEL EXPANSION OF OVERFILLED
TANKS CAN RESULT IN FUEL ENTRY TO ENGINE

LOCK.
IF THE ORIGINAL FUEL TANK CAPS ARE LOST,
REPLACE THEM WITH BUHLER VERSATILE CAPS
AND TIGHTEN SECURELY.
