23. Loosen the Plug on the “UP” Hydraulic Hose,
then position the end of the “UP” Hydraulic
Hose

and force the oil out of the “UP” Hydraulic Hose
until the oil runs clear with no foaming or air
evident in the oil.

26. Remove the Plug from the “UP” Hydraulic Hose
and reconnect the “UP” Hydraulic Hose to the
Lower Cylinder Fitting.
27. Press the hopper raise button to raise the
cylinder ram to the end of its stroke to purge
the oil from the top of the hydraulic cylinder.
Check the oil level in the reservoir frequently
as you do this and add oil as necessary. The
oil level in the reservoir should be at the MIN
line with the cylinder ram fully-extended
upward.
Note: Be careful not to let the oil level in the reservoir fall below the MIN line to avoid introducing
air into the clevis end of the cylinder. If this happens, you will have to restart the procedure
from step 8.
