Purge Hydraulic System
DANGER
!
To avoid serious injury or death:
Never remove or install a folding wing cylinder with cylinder
rod retracted and wing folded-up. The wing is unstable
without its folding cylinder and can suddenly fall. Also, air
trapped in a new or repaired cylinder will drop the wing
suddenly when lowering the wing. Either situation can render
the cutter inoperable and cause serious bodily injury or death.
WARNING
!
To avoid serious injury or death:
Be sure center and wing decks are lowered to the ground and
all hydraulic pressure is relieved before disconnecting any
hydraulic lines or fittings to purge the hydraulic system.
Wing Fold Cylinder
Refer to Figure 1-21:
1. Lower center deck until it is supported by stroke
control spacers (#6) on hydraulic cylinder (#5).
2. Lower wing deck until it is resting on the ground.
3. See
Shut tractor down properly and move wing control
lever back and forth to relieve all hydraulic pressure.
4. Slightly loosen hydraulic hose fitting (#7) at wing
cylinder (#4) to allow air and fluid to escape.
5. Restart tractor and slowly activate tractor control
lever to retract wing cylinder (#4) and to purge
trapped air from the hydraulic system.
6. Repeat steps 2 & 3 above once air is purged from the
wing hydraulic system.
7. Tighten hose fitting at wing cylinder (#4).

Deck Lift Cylinder
Refer to Figure 1-21:
1. Lower center deck until it is supported by stroke
control spacers (#6) on hydraulic cylinder (#5).
Shut tractor down properly and move deck lift control
lever back and forth to relieve all hydraulic pressure.
3. Slightly loosen hydraulic hose fitting (#8) at deck lift
cylinder (#5) to allow air and fluid to escape.
4. Restart tractor and slowly activate tractor control lift
lever to extend lift cylinder (#5) and to purge trapped
air from the hydraulic system.
5. Repeat steps 1 & 2 above once air is purged from the
deck lift hydraulic system.
6. Tighten hose fitting at lift cylinder (#5).
