Do not connect the cylinder rod until system has been charged with oil.
1. Prop up the cylinder with a block of wood (fig 1). Check to see that the
rod will extend completely without striking anything.
2. Connect tractor
(note: check to see that all cylinders extend and retract in sync.
If one goes backwards, check the plumbing.)
3. Extend cylinders completely, hold lever for 30 sec. as air exits cylinder.
4. Retract cylinder completely, hold lever for 30 sec. as air exits.
5. Repeat steps 3&4 three times.
6. Install cylinder pins. Be sure washers are installed correctly (see fold
cylinder parts page).
Air in the wing cylinder will cause wings to fall to the ground!!!
Whenever air could have entered the cylinders, repeat the process above to
purge circuit.
ALWAYS UNFOLD WINGS before working on hydraulics!!!
Never work on a lift
system with the wings folded
Fig 1. When charging the circuit, prop up
cylinder with block of wood. Be sure the
rod can extend freely without striking
anything.
