MAINTENANCE INSTRUCTIONS
G719
REPLACING THE HYDROSTATIC STEERING HOSES
The hoses must be replaced after four years from the production date (the date is in-
dicated on their surface) or after 3600 hours of work of the tractor or immediately af-
ter discovering signs of their damage (hose sweating, local buckling, leaks of the
working media around the end pieces and on the hose surface, abrasion of the hose
surface to the metallic reinforcement).
In case of a pump failure or after stopping of the engine the steering capability
is maintained, but the required steering force gets higher. You can drive the
tractor at a reduced speed to the nearest workshop.
The steering wheel must not be held in the limit turning angle positions for a
long time (the maximum time is 20 s); otherwise the oil in the hydrostatic
steering circuit is heated up excessively.
