* At 1.013 × 10 Pa (760 mmHg) pressure (atmospheric). A higher boiling point is
obtained by using a radiator pressure cap which permits the development of
pressure within the cooling system.
NOTE
• The above data represent industry standards that
necessitate a minimum glycol content in the concentrated
antifreeze.
Bleeding Fuel System
Air must removed:
1. When the fuel filter or lines are removed.
2. When tank is completely empty.
3. After the tractor has not been used for a long period of time.
CAUTION
• Do not bleed the fuel system when the engine is hot.
Bleeding procedure is as follows:
1. Fill the fuel tank with fuel, and open the fuel valve (1).
2. Open the air vent valve (2) on the fuel injection pump.
3. Start the engine and run for about 30 seconds, and then stop
the engine.
4. Close the air vent valve.
IMPORTANT
• Always close the air vent valve (2) except for bleeding fuel
lines. Otherwise,
frequently.
