Operating manual

6. When selecting and purchasing new tires, consider the recommendations of this manual.
Incorrect installation and removal of tires causes damages to the structural elements of the tire.
Install and remove tires only using special equipment. On one axle, install tires of the same size,
model and design. Periodically interchanging the wheels prevents their uneven wear. Do not install
wheels with varying degrees of wear on the same axle. Using old tubes for new tires is not
recommended.
7. When installing paired wheels on the same axle, ensure internal pressure in accordance
with the recommendations.
8. When setting the track, make sure to provide equal distances of the opposite wheels
relative to the centerline of the tractor. When installing the wheels, observe the correct direction of
tire rotation and sufficient distance between the wheel and the other structural elements of the
tractor (eg. cabin).
9. Protect tires from contact with fuels, oils and other petroleum products.
10. Avoid sharp set-offs, sharp braking and sharp turns, long slipping of wheels when the
tractor gets stuck.
11. Do not operate the tractor and avoid long stops on damaged or flat tires.
12. If the tire pressure constantly drops, find the cause and correct it.
13. Check the pressure in tires filled with solution when the valve is in its topmost position.
Notes.
1. Changing the rated tire load depending on the speed is applied in the cases when the tire
is not subjected to long operation at high torques.
2. During the field work and other conditions of continuous operation at high torques, use
the values corresponding to the speed of 30 km/h (see table below).
6.6.2 Allowed combinations of front and rear tires
Attention!
On tractors with FDA, use a correct combination of front and rear tires. Using
correct combinations of front and rear tires provides maximum performance of the tractor,
increases the tire life and reduces wear of the power gear components. Combining new and worn
tires or tires of different diameters or different rolling radius can result in violation of the
requirements for kinematic mismatch and, as a result, excessive wear of tires and breakdowns of
FDA parts. Table below lists allowed combinations of front and rear tires.
