Hydraulic Fold System - Landoll 2132 Operator's Manual

OPERATION AND MAINTENANCE

Hydraulic Fold System

1. The 2132 Coulter Chisel is equipped with a hydraulic
fold system to raise and lower the wing frames for
narrow transport.
2. Be sure the system is fully charged with hydraulic oil
before attempting to fold/unfold the unit. Air in the
system can allow uncontrolled dropping of the wing
frames causing serious personal injury or machine
damage. The system needs to be charged with oil
initially and any time the system has been opened for
repair such as cylinder, hose, or fitting
replacement/repair.
3. To charge the system, carefully hitch the coulter
chisel to the tractor. Unpin the end(s) of the fold
cylinders, and position them so they can extend and
retract without contacting any frames or other parts.
Check the tractor hydraulic fluid level to make sure it
is full of the manufacturer's recommended hydraulic
fluid. Connect the cylinder hoses to the tractor and
fully extend and retract the cylinders several times.
The cylinder rod travel should be smooth and positive
when all air has been purged from the system. Due
to large amounts of hydraulic oil required, recheck
the tractor fluid level to make sure it is within proper
operating limits.
4. The hydraulic fold system is equipped with restrictors
in the rod end of cylinders to prevent uncontrolled
falling of wing frames when unfolding. Removal or
improper assembly of these restrictors can cause the
machine to fold improperly and result in serious
machine damage.
