IMPORTANT! Always before settings, the AC 5 / 5.2 must
be tested in the test mode and it must be sure that the trac-
tor electrical system (battery, fuses etc) and low pressure
circuit of the hydraulic system are in order. When carrying
out settings the gearbox oil must be in the normal operating
temperature (+30...+60 ˚C) and the engine in the normal
operating temperature. Otherwice the calibrations do not
succeed. Remove possible DPS pre---programmed speeds.
Before changing the setting values, note down the original
values).
