Hydraulic system

5.7 Mechanical control

All hydraulic functions of the 803 are controlled mechanically.
Accessing the elements of the mechanical pilot control requires
removing the plastic trims 

– see chapter 5.9

 Plastic trims

 on page 5-22.

Control levers (up to serial no. AI00814)

Setting the control levers

☞

Replacing damaged elements requires setting the control levers again.

☞

Enable and disable the lock and watch the control levers as you do so.

☞

Once the lock is disabled, the control levers automatically return to their neutral posi-
tions if they are not set correctly.

☞

The position of the control levers can be modified by means of the adjustment linkage, 
so that the control levers remain in their positions when disabling the lock.

☞

Check for correct setting.
