Start-Up And Hydraulic Operation (Cont’d)
Initial Start-up Procedure for Wing Lift Hydraulic
Cylinders (cont’d)
Figure 18
This disk has a Master Slave Hydraulic Lift System. Fully
extend hydraulic cylinders (item 1) and maintain hydraulic
pressure for 30 seconds to insure all air is purged from
the system.
NOTE: As oil is pumped into the base end of master
cylinder, oil is forced out of the rod end into
the base end of each slave cylinder. To
compensate for the smaller volume of oil in
the rod end of the master cylinder, each slave
cylinder is 1/2” smaller in diameter. When
cylinders are fully extended, oil will bypass
through a rephasing slot on each cylinder in
order to equalize the system. The tractor SCV
lever must be held for a few seconds to
accomplish this passage of oil through the
system.
Figure 19
Install the wing lock pins (item 1) in the storage holder.
Figure 20
Raise the implement to maximum height. Remove the
lock pins and move the wheel locks to the storage
position and install the lock pins (item 1).
