MAINTENANCE
NOTE: The complete lubrication of housing 1 is done the first time at the manufacturers plant, after which it
must be topped up periodically, as according to the lubrication chart. A complete change or fill is necessary
only for the replacement and /or repairing of the entire gearbox or internal parts. In this case, it is necessary to:
remove caps H-K and inject the grease, using grease pump W, into hole T until the grease comes out of hole
K. Then screw caps H-K back into place on center gearbox 1. Use Multi-Purpose Gear Oil.
Periodic checking and topping up of central gearbox 1:
-Each time the Cardan Driveline is disconnected and whenever the machine is stopped, it is recommended
that power takeoff shaft be cleaned, and replace the protective cover.
-Each time the machine is connected to the tractor.
