Repeat steps 1 through 4 to check the results
Adjust the upper panel hydraulic detent
Note: The upper panel has a hydraulic detent for
down set @ 2400 PSI and mechanical detent for the
up function. and is adjusted mechanically. (see Upper
Panel Kick-out Adjustment Procedures).
Note: All mechanical linkage must be free of any
binding.
1. Lower the main relief pressure by turning the main
relief adjusting screw out (counter clockwise) 4
turns.
2. With the engine and pump “on” move the upper
panel control lever to shift the spool in the down
direction. The upper panel will travel to the end of
the down stroke but will not release the dent and
shift to the neutral position.
3. Slowly turn the main relief valve adjusting screw in
(clockwise) to increase the pressure. Watch the
pressure gauge to see what the pressure is when
the spool kicks out of detent and returns to the
neutral position. The correct kick-out pressure for
the lower panel is 2350 +/-50 PSI.
5. If the setting is incorrect, place the unit in the
lockout position and remove the rubber plug from
the end of the upper panel spool to expose the
detent release adjusting screw.
6. Insert a screwdriver and turn the detent adjusting
screw in (clockwise) to increase the kick-out
pressure or out (counterclockwise) to decrease the
pressure.
