MAINTENANCE CONTINUED
:
6. WING LIFT CYLINDER REMOVAL - See Fig. 15. If possible
lower wings to field position if the wing lift cylinder hydraulic
system must be serviced or repaired. If wing lift cylinders
must be serviced or repaired with wings in folded position,
install a safety chain between each wing frame and main
frame to prevent wings from falling down. Always install a
chain on both wings even if only one cylinder is being worked
on.
Fig. 15
CAUTION:
IF WING LIFT CYLINDER(S) OR WING LIFT HYDRAULIC HOSES ARE REMOVED WHEN WINGS ARE FOLDED INTO TRANSPORT
POSITION, ALWAYS INSTALL A SAFETY CHAIN BETWEEN EACH WING FRAME AND MAIN FRAME TO PREVENT WINGS FROM
FALLING. IF WINGS FELL SERIOUS INJURY OR DEATH COULD OCCUR TO PERSON(S) NEARBY AND MACHINE WOULD BE
DAMAGED SEVERELY.
7. Keep all safety decals clean and in good condition to provide a constant reminder of safe operating procedures.
8. Replace any destroyed, missing or illegible decals and reflectors.
9. At the end of each season do following:
a) Relieve pressure in all hydraulic cylinders. Disconnect hydraulic hoses from tractor and cap them.
(b) If disc is to be stored outdoors, cover hydraulic cylinders and hoses with weather proof material and coat all exposed cylinder shafts with
grease.
(c) Set planks under each wheel.
(d) Lubricate all grease points.
(e) Check disc for worn or damaged parts. Replace damaged parts during the off season.
(f) Touch up any scratches with EZEE-ON paint.
CAUTION: ALWAYS RELIEVE THE PRESSURE IN HYDRAULIC SYSTEM AND CLOSE BOTH HYDRAULIC LOCKUP VALVES WHEN DISC IS
NOT BEING USED
.

VERY IMPORTANT:
WHEN STORING DISC DO NOT LEAVE CYLINDERS UNDER HYDRAULIC PRESSURE, ESPECIALLY IF CYLINDERS ARE
ACTIVATED DURING COOL TEMPERATURES. THE THERMAL EXPANSION OF OIL WHICH TAKES PLACE WHEN THE
MACHINE IS IN A WARMER ENVIRONMENT MAY CAUSE SERIOUS DAMAGE TO CYLINDER, LINES OR HOSES. ALWAYS
RELEASE HYDRAULIC PRESSURE AND CLOSE LOCKUP VALVES BEFORE UNHITCHING FROM TRACTOR.
IMPORTANT: WINGS MAY UNFOLD DUE TO THERMAL
EXPANSION OF HYDRAULIC OIL CAUSING
DAMAGE TO CULTIVATOR, PROPERTY OR
SEVERE INJURY OR DEATH TO PERSON(S)
NEARBY. RELEASE PRESSURE IN ALL
CYLINDERS AND CLOSE HYDRAULIC
LOCKUP VALVES BEFORE UNHITCHING
FROM TRACTOR OR WHEN PARKING WITH
TRACTOR.
