The complete lubrication of gearbox 1 is done the first time at the manufacturers plant, after which it must be
topped off 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:
Every 100 hours of working time, check and top off central gearbox 1. It is a good practice, however, t check
the condition and quantity of grease after all long periods of inactivity, especially when starting to work again
after the winter break. To top off the grease in central gearbox 1 it is necessary to: remove caps H-K and inject
the proper amount of grease into hole J, using grease pump W. Then screw caps of H back into place on
housing 1.
