WARNING
CAUTION
HIGH ALTITIDE AND LOW TEMPERATURE FUELS
Fuels with cetane numbers higher than 40 may be needed in high altitudes or extremely low ambient
temperatures to prevent misfires and excessive smoke.
COLD WEATHER FUEL
At opening temperatures below 0 degrees C (32 degrees F) use a blend of No.1D and No.2D fuels, also
know as “winterized” No.2D. NOTE: No.1D fuel can be used; however, fuel economy will suffer.
Use low sulfur content fuel having a cloud point that is at least 10 degrees below the lower expected fuel
temperature. Cloud point is the temperature at which wax crystals begin to form in diesel fuel.
The viscosity of the fuel must be kept above 1.3 centistokes to provide adequate fuel system lubrication.
ENGINE FUEL FILTER
See engine manufactures operator/instruction manual for the proper fuel filter replacement changing intervals
for the brand engine in your Boss compressor.

DO NOT MIX GASOLINE OR ALCOHOL WITH DIESEL FUEL. THIS MIXTURE
CAN CAUSE AN EXPLOSION.
DUE TO THE PRECISE TOLERANCES OF DIESEL INJECTION SYSTEMS, IT IS
EXTREMELY IMPROTANT THAT THE FUEL BE KEPT CLEAN AND FREE OF DIRT
OR WATER. DIRT OR WATER IN THE SYSTEM CAN CAUSE SEVERE DAMAGE TO
BOTH THE INJECTION PUMP AND THE INJECTION NOZZLE.
USE ASTM NO.2D FUEL WITH A MINIMUM CETANE NUMBER OF 40. NO.2 DIESEL.
FUEL GIVES THE BEST ECONOMY AND PERFORMANCE UNDER MOST
OPERATING CONDITIONS. SEE ENGINE MANUFACTURES OPERATORS/
