hydraulic lines under pressure. Always wear
gloves and eye protection.
8. After the trailer has settled on the blocks, remove
the cover on the trailer frame, above the axle, to
expose the upper end of the lift cylinder. See Fig.
5.31.
9. Remove the cap from the accumulator valve and
connect the nitrogen bottle. See Fig. 5.32. Pressurize
the accumulator to
650 psi
. Do this on both
cylinders. Remember, oil will come out of the hoses
as the accumulator is being repressurized.
10. Replace the cap on the valve and replace the cover
over the cylinder.
11. Go back to the hydraulic valve and reconnect the
hoses.
12. Reconnect the hydraulic hoses to the tractor. Start
the tractor and engage the tractor’s hydraulic valve
to allow oil to the sprayer. Turn on the suspension
electrical switch. The suspension cylinders should
extend, raising the trailer frame off the blocks placed
in step #2.
13. Switch off the suspension electrical switch, disengage
the tractor hydraulic valve and turn off the tractor.
14. Remove the blocks placed in step #2. Check the
hydraulic valve and hoses for oil leaks. Repair if
necessary.
Refer to section 6.14 to adjust the suspension micro
switches, if necessary.
