For executing the 10° or 20° steering for calculating: caster, king pin angle, included angle, toe-
out on turn at 20°( fig. 12).
If turntables with graduated scales are fitted, maximum steering can also be measured visually
and the reading performed can be entered in a suitable window using the keyboard.Admitted
values range from 21.00° to 99.99°; if a value out of that range is entered, the program changes
the entered value to the lowest admitted value (21.00°).

To perform the standard steering procedure, follow the on-screen instructions and proceed as
described below:
• release the turntables;
• align the wheels by following the on-screen indicator until "STOP" is displayed;
• Lock all the targets. The
target perpendicular to the floor.
• turn the wheels 10° or 20° to the left until the "STOP" message is displayed;
• wait for the data acquisition and for the turn-right arrows to appear;
• turn the wheels 10° or 20° to the right (relative to the centre position) until the "STOP"
message is displayed;
• wait for the data acquisition and for turn-left arrows to appear;
• turn the wheels back to the left to straighten the steering.
If the full steering procedure has been selected, proceed as follows:
• release the turntables;
• align the wheels by following the on-screen indicator until "STOP" is displayed;
• Set the graduated scale necessary for measuring maximum steering to zero on both
turntables.
• Lock all the targets. The
target perpendicular to the floor.
• turn the wheels 10° or 20° to the left until the "STOP" message is displayed;
• wait for the data acquisition;
• turn the wheel further to the left until the steering wheel locks;
