The flow control valve
(Figure 15 on page 23) controls
the leveler's descent
1 Leveler must be adjusted to lower from full raised
position (with lip extended) so the header stops in
8 to 12 seconds
2 Press RAISE button and run the platform up until the
lip extends
3 Release RAISE button and allow the platform to fall
completely below dock and stop Verify with a stop
watch that the platform lowers according to Step 1
If not, readjust flow control valve
4 Loosen locknut on valve to set flow control valve
• To lower the leveler slower – Turn in (clockwise) in
1/4 turn increments
• To lower the leveler faster – Turn out
(counterclockwise) in 1/4 turn increments
Or, set valve at starting point (3-1/2 turns clockwise
from fully out)
5 Repeat procedure to verify lowering time as needed
according to Step 1 1/8 turns may be necessary to
fine tune the adjustment
6 Tighten locknut on flow control valve
The sequence valve (Figure 15 on page 23) controls
the lip extension
1 When the leveler is fully raised and the lip does not
extend, the sequence valve is set too high
2 Loosen adjustment nut
3 Turn adjustment screw in completely (clockwise) with
an Allen wrench
4 Turn adjustment screw counter-clockwise to get to
factory starting point:
• For power units built before April 2015: 2-1/2 turns
• For power units built after March 2015: 5-1/2 turns
Tighten adjustment nut once at factory starting point
5 Press RAISE button and run the platform up until the
lip extends
6 Verify that the lip extends only at the top of the ramp
cylinder stroke If not, continue with sequence valve
adjustment
• Turn adjustment screw out (counterclockwise) in
1/8 turn increments Lip will extend more quickly
• Turn adjustment screw in (clockwise) in 1/8 turn
increments Lip will extend more slowly
7 Release RAISE button and allow the platform to fall
completely below dock and stop
8 Verify that the lip will fall to pendant as the platform
is raised up to store the lip in the keepers If lip
re-extends, turn adjustment screw in (clockwise) in
1/8 turns and retest
9 Re-test the unit several times to verify the setting
