CAUTION
Fig 1. When charging the circuit, prop up
cylinder with block of wood. Be sure the
rod can extend freely without striking
anything.
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
Identify the fold hose ends with green hose grips for quick hookup
to tractor.
CHARGING THE FOLD SYSTEM
Do not connect the cylinder rods until system has been charged with oil.
1. Prop up the cylinders with a block of wood (fig 1). Check to see that the rods 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 cylinders completely, hold lever for 30 sec. as air exits cylinder.
5. Repeat steps 3&4 three times.
6. Install cylinder pins. Be sure washers are installed correctly (see fold cylinder parts page).
