1. Before starting the tractor check the oil level using the

dipstick (1).

NOTE: The dipstick is only accurate if the tractor is not

running and sitting on a level surface.

2. Remove the dipstick from the engine.

3. Wipe the dipstick with a lint-free cloth.

4. Insert the dipstick in the engine.

5. Remove the dipstick and read the oil level

6. The oil level should be between the (L) and (H). See

figure 3

Engine cooling system - Check

Cooling system

WARNING

Hot liquid under pressure!

Scalding can result from fast removal of the radiator cap. Check and service the engine cooling sys-

tem according to the maintenance instructions in this manual.

Failure to comply could result in death or serious injury.

W0163A

The tractor engine must operate at the correct temperature to obtain maximum efficiency and service life. This is

dependent on the cooling system.

Only check the cooling system when the engine is “OFF” and the cooling system is cool. Never add coolant to a

hot cooling system. Never remove the radiator cap when the cooling system is hot.

Always fill the system with a 50/50 solution of ethylene

glycol antifreeze and water.

Checking the coolant level

1. Visually inspect the coolant level in the coolant recov-

ery reservoir (1) the coolant level should be between

the "LOW" and "FULL" lines located on the side of the

reservoir.

2. If the coolant level is not between the "LOW" and

"FULL" lines, add coolant as necessary. The cooling

system already contains antifreeze, add only antifreeze

solution of the correct water/antifreeze mixture. Pure

water will dilute the solution and weaken its protection.

7 - MAINTENANCE

3. If there is not coolant in the coolant recovery reservoir

remove the cap (2) from the radiator.

NOTE: Only remove the radiator cap when the cooling sys-

tem is cool.

4. Add enough coolant to the radiator so the coolant level

is even with the bottom of the filler neck.

5. Install the radiator cap.

To adjust the clutch pedal:

1. Loosen lock nut (1) and rotate adjuster (2)

2. Tightening the adjuster will decrease the free play travel

and loosening the adjuster will increase the free play

travel.

3. Tighten the lock nut when the correct free play travel is

obtained

4. Check clutch for disengagement when clutch pedal is

fully depressed.

7 - MAINTENANCE

Belt - Check

1. A belt-driven fan located at the front of the engine draws

air through the fins of the radiator to lower the temper-

ature of the radiator coolant.

2. When 10 kg (22 lb) of pressure is applied midway (A)

between the belt pulleys, a correctly tightened belt will

deflect 10 - 12 mm (0.4 - 0.5 in).

3. If the fan belt is slipping, fan efficiency is lowered, re-

sulting in the engine running too hot. If the belt is too

tight, the life of the alternator bearing will be shortened.

If the fan belt shows signs of cracking or fraying, install

a new one.

4. If the belt requires adjustment see page 7-54 for this

procedure.

Mechanical service brakes - Check

Whenever brake pedal travel becomes excessive, or if

the travel of one pedal is unequal to that of the other,

each pedal should be adjusted.

1. Loosen the locknut (1) and rotate the brake rod (2) until

there is (A) = 50 - 60 mm (1.97 - 2.36 in) of pedal free

play. Lengthening the rod increases free play. Short-

ening the rod decreases free play.

2. Test drive the tractor to make sure the braking action of

both rear wheels is equal. Readjust as necessary.

NOTE: Note Hydrostatic transmission tractors are shown

in figure 1 and mechanical transmission tractors are shown

Fuel injection system - Bleed

WARNING

Escaping fluid!

Hydraulic fluid or diesel fuel leaking under pressure can penetrate the skin and cause infection or

other injury. To prevent personal injury: Relieve all pressure before disconnecting fluid lines or per-

forming work on the hydraulic system. Before applying pressure, make sure all connections are tight

and all components are in good condition. Never use your hand to check for suspected leaks under

pressure. Use a piece of cardboard or wood for this purpose.

If

injured by leaking fluid, see your

doctor immediately.

Failure to comply could result in death or serious injury.
