Tilt Ram Fully Extended
K Fig 22. ( T E-26)
If the Quickhitch tilt ram 5 reaches the end of its stroke
during the self level cycle, or the operator selects the tilt
ram service, the loader arm will continue to raise. The
unloading spool 4d will shift to the left and unload the flow
going to the tilt ram head side. The oil flows back to tank
thus preventing the loader arm ram from stopping during
the ‘raise’ function. Check valve 4e closes to prevent
pressure loss from the tilt ram.

Loader Arm Lower
K Fig 23. ( T E-26)
When the loader arm spool 9B is selected to ‘lower’, oil
flows to port ‘B’ on the self level valve. Flow enters the self
level valve 4, opens the lift check 4a and flows out at port
‘A’ to the rod side of the lift ram 2. Flow from the head side
of the ram is directed back to the loader valve 9 and returns
to tank.
