Checking Engine Oil Level
Check the engine oil before starting the engine or ‘5’
minutes or more after the engine has stopped.
To check the oil level, draw out the dipstick, wipe it
clean, insert it and draw it out again. Check to see that
the oil level lies between the two marks.
Add oil only when the oil level reaches the lowest mark.
Caution -Do not run the engine if the oil level is low than specified.
Checking Coolant Level
Check coolant level in recovery bottle & Top-up if
required.
Use redimix coolant for top up.
Warning -Do not open the coolant cap when the engine is hot. Do not
remove the radiator cap when the engine is hot
Checking Radiator Fins
Clean chaff guard daily or earlier if chocked.
Blow compressed air through the radiator fins to
remove foreign material
Caution -To avoid personnel injury, ensure to stop the engine before
working on radiator.
Checking Radiator Fins
The tension is correct when the belt can be pressed by
thumb to 9 - 12 mm. midway between the two pulleys
without much effort.
In case the tension is not correct then adjust the tension
by adjusting alternator position on brace plate.

Checking tyre pressure
For normal load and operation of the tractor the following tyre pressure is recommended.
Note:
1. Keep the tube valve always closed with the dust cap, to protect the valve from mud/dust/slush.
2. To achieve best performance and maximum tyre life, maintain air pressure as per tyre size and
load carrying capacity as recommendation.
Addition of Wheel Weights At Rear – To increase drawbar pull of the tractor & reduce wheel slip
(Increase tyre life)
Cast Iron weights can be attached to the rear driving wheels.
In case the slip continues, it may be necessary to liquid ballast the tyre.
Adding Water:
Tractor tyre can be 80% filled with water as follows, Remove excess air from Tyre.
1. Remove all air from tyre.
2. Raise the wheel. Rotate the tyre until the valve, stem is at 1’O Clock position.
3. Remove the valve core housing and screw on the adapter.
4. Force water into the tyre from a tank placed at least five feet higher than the tractor tyre, or by
using a compressor and pressure tank filled with water.
5. When the liquid has reached the required level, remove the adapter, screw in the valve core and
inflate to the recommended pressure.
6. Maintain air pressure as per recommendation.

Front Axle - Front Wheel “Toe In Check”
In the event of the tie rod setting being interfered with, then it is necessary to adjust the TOE-IN.
Before measuring and adjusting the TOE-IN, ensure the front wheels are in the straight ahead
position and the front axle is not tilted. Calculation of Toe In-: (Refer image TOE-IN ADJUSTMENT)
Measure distance between centres of both front wheels from front of tractor. Let that distance be
“Y”. Now adjust track rod ball joints such that distance” will remain same in front side of front
wheels and at rear side of front wheel distance will increase in 4 to 6 mm. let distance let distance
in rear of Front wheel be “X”. Therefore X= (Y+4) To (Y+6) in mm
Toe In Adjustment
Procedure To Adjust Toe In-:
Loosen check nut of wheel cylinder from both sides and adjust Toe in position of front wheel.
While adjusting position maintain centre of ram in wheel cylinder with exact centre of Front axle
position.
