4.12 Hydraulic Suspension System Maintenance
The tractor’s lifter has been properly adjusted at the factory and there is no need for the user to do it again.
But during use, the adjusted state can change, which will impact the normal operation of the tractor because
of wear and loosening of the bar driver pair.
When the force-adjusted spring assembly is mounted, the regulating washer may be used for adjustment,
which doesn’t allow clearance on the spring after mounting.
4.12.1 Control Handle and Feedback Lever Adjustment
 Install the lifter on the tractor, connect the hoses and fill the
hydraulic oil reservoir.
 Mount the suspension bar and hang a load of approximately
200-300 kg. at the lower suspension point. Place the control
handle in the lowest position.
 Start the engine and set the throttle in the neutral position.

 Slowly move the control handle up and the lift arm
and load will rise. When the handle reaches its peak, the
angle should be 53° between the lift arm; the level is normal.
If the angle between the lift arm and the level is less than
53°, it should be adjusted.
 When the angle between the lift arm and the level is
less than 53°, the bolt (1) on the feedback lever can be used
toincrease the length of the feedback lever until it conforms
to the requirements.
 Tighten the nut (2) after adjustment. Fig 4-21 Feedback Lever Adjustment
