13.4.5 Transition/mast separation calibration
This should be performed after height measurement calibration if
height measurement (option) is available.
The top box gives the flow on transition from free lift to main lift, in order
to obtain smooth transition between free lift and main lift.
The bottom box gives the flow on downward transition. The units are in
%, with a minimum value of 15 and a maximum of 60.
1. Start by lifting the forks at full speed from free lift to main lift.
2. If transition is not felt to be smooth enough, reduce the value in the
top box using the plus/minus buttons (numerical buttons are not
supported).
3. If the forks do not reach "free lift top" within a reasonable time (sev-
eral metres into main lift), raise the value.
4. Repeat stages 1–3 until the upward transition is satisfactory.
5. Lower the forks at full speed from main lift to free lift.
6. If main lift hits the "bottom" too hard, reduce the value in the bottom
box.
7. If the forks do not reach "main lift bottom" within a reasonable time
(several metres into main lift), raise the value.
8. Repeat stages 5–7 until the downward transition is satisfactory.
