GENERAL

9. CHECK AND MAINIENANCE 9.1 DAILY CHECK Walk Around Inspection

For your own safety and maximum service life of the machine, make a thorough daily inspection before operating the machine to start the engine.

Look around and under the tractor for such items as loose bolts, trash build-up, oil or coolant leaks, broken or worn parts.

CAUTION To avoid personal injury: • Be sure to check and service the tractor on a flat place with the engine shut off and the parking brake “ON”.

A. CHECKING AND REFUELING Fuel tank capacity

58.0 (15.32 U.S.gal.)

CAUTION To avoid personal injury: • Do not smoke while refueling. • Be sure to stop the engine before refueling. 1. Turn the key switch to “ON”, check the amount of fuel showing on the fuel gauge. 2. Fill fuel tank when the fuel gauge shows 1/4 or less fuel in the tank.

C45W112A

3. Use grade No.2-Diesel fuel at all temperatures above -10°C (14°F).

(1) Fuel Tank Cap

IMPORTANT

NOTE:

Do not permit dirt or trash to get into the fuel system.

Be careful not to let the fuel tank become empty, otherwise air will enter the fuel system, requiring the fuel system to be bled before next engine start.

Be careful not to spill during refueling. If a spill should occur, wipe it off at once. Fuel on the tractor may cause a fire.

To prevent condensation( water) accumulation in the fuel tank, fill the tank before parking the tractor overnight.

No.2-D is a distillate fuel of lower volatility for engines in industrial and heavy mobile service. (SAE J313 JUN 87)
