CHARGING THE CIRCUIT
ATTENTION
On hard ground, do not retract cylinders all the way while tongue is hitched to
tractor. The tractor drawbar can be
bent
upwards.
Connect only the Barrel end of the cylinders until the circuit has been charged.
1. Be sure that all cylinders can extend completely without striking anything. Prop with blocks
if necessary.
2. Connect Tractor.
3. Extend cylinders and hold lever for 2-3 minutes. This will purge the air from the circuit.
(The lift cylinders have a port that allows oil to pass when completely extended.)
4. The circuit is now free from air. Install Rod end Pins. Connect tongue telescope.
Whenever air could have entered the cylinders, repeat above steps to purge circuit.
Test wing fold and adjust hose droop at wings if necessary.
