FUEL SYSTEM

Service Specifications

Fuel Filter Cup Service Interval ......................................... Every 10 Hours

Fuel Filter Element Change ...................................... Replace when loss of power or misfiring occurs

This type filter cannot be cleaned. Change the filter when the engine is misfiring or a loss of power is evident. It is necessary to remove the air from the system after each replacement. Only a filter recommended by your dealer should be used, to be sure that it is both effective and capable of withstanding the required suction or pressure without damage to the filter element. Fill the fuel tank at the end of each day to reduce condensation.

NOTE: Do not fill the fuel tank to its full capacity. Space is required for vapor expansion in the event of a temperature change. A tank filled to capacity may overflow if exposed to a rise in temperature or direct sunlight.

Water Removal from the Filter Cup

Before starting each day ’ s work, check for water or sediment in the filter cup. If water or sediment is in the cup, remove filter cup, clean and reinstall.

NOTE: Be careful not to allow dirt, water and other foreign materials to get into the filter when cleaning the cup.

Diesel Fuel Specifications

Use a good grade of Number Two Diesel Fuel in your Diesel Engine. Do not use other types or grades of fuel. The use of other fuels will result in loss of engine power and high fuel consumption.

NOTE: When the temperature is very cold, the use of a mixture of Number one and Number Two Diesel Fuel is permitted for a short period of time. See your fuel Dealer for winter fuel requirements in your area.

Fuel Filter Element Replacement

To replace the filter element, use following procedure:

Close the fuel shut-off valve. Install new filter element. Assemble filter cup and retaining nut to filter body.
