Setting up the draft control sensor
The draft force generated through the lift system is monitored by way of a strain gauge that measures the deformation
of a spring rod. For maximum monitoring precision, the sensor must be properly set up.
Proceed as follows:
— Connect the All Round Tester to the electronic control unit. Access the "Lift P" menu and select option 5 (monitor);
— Position the lift arms at mid height, without any implement attached;
— Check the “draft” parameter in the monitor video page. If the value is other than 30%, remove any mechanical
protectors that may be fitted to the sensor and adjust in such a way that the reading shows 30%. Retighten and
secure the lock nut on the threaded body of the sensor and reinstate the protectors (see figs 11 and 12, pages
256 - 257).
Setting up the steering sensor
Some machines (only those with the SBA system) also have a steering sensor mounted to the left hand end of the
front axle. To ensure the SBA system operates with optimum efficiency, the sensor must be set up initially.
Proceed as follows:
— Connect the All Round Tester to the electronic control unit. Access the "Lift P" menu and select option 7 (steering).
— Position the wheels absolutely straight and press "E" at the tester.
Verify the operational efficiency of the system’s electrical components.

display; check also that the caption “handset” appears.
— Press the Down button at the handset and check that the letter "P" appears alongside the “Down” caption on the
tester display; check also that the caption “handset” appears.
External buttons
— Connect the All Round Tester to the control unit.
—Access the "Lift P" menu and select option 1 “Tests".
— From the "Tests" page, select option 2 “Ext button/handset"
— Press the external Up button mounted to the fender, and check that the letter "P" appears alongside the “Up”
caption on the tester display; check also that the caption “external” appears.
— Press the external Down button mounted to the fender, and check that the letter "P" appears alongside the “Down”
caption on the tester display; check also that the caption “external” appears.
— Repeat the test for both buttons mounted to the fender.
