NOTE
:
The free play of the left and right brake pedals of the tractor must be adjusted to be even.
Otherwise, the tractor will pull to one side when emergency braking.
4.4 Differential Lock Adjustment
Adjustment of differential lock is performed through adjustment of the bolts (1 and 2). During the adjustment,
the clearance between the right coupling (3) and left coupling (4) is about 2 mm. Loosen the nut (2) and rotate the bolt
(1) inward, and the clearance increases. Rotate the bolt (1) outward, and the clearance decreases. After adjustment,
tighten the nut (2).

4.5 Hydraulic Steering Oil Tank Inspection and Maintenance
The hydraulic steering oil tank is mounted on the right side of the engine hood. Open the oil tank cover, pull the
dipstick and inspect the dipstick for oil. If there is no oil on the dipstick, it indicates an insufficient amount of oil in
the steering oil tank. You need to locate the oil leak, repair it and then refill the oil to the central mark on the dipstick.
The hydraulic steering oil tank, oil line and fittings should be inspected systematically and thoroughly for oil leaks,
otherwise it may result in steering trouble. The oil tank’s internal filter should be cleaned or changed regularly.
When checking the oil level, also check the ventilation valve (rivet style) in the center of the oil tank cover to make
sure it operates properly. Clean it if any oil or grime affects its operation.
