MAINTENANCE INSTRUCTIONS
G719
REPLACEMENT OF HYDROSTATIC STEERING HOSES
The hoses shall be replaced after four years from the date of their manufacturing (the
date can be found on their surface) or after 3,500 Mh of the tractor or in case that any
traces of their damage are found (weeping of a hose, local bulging, leakage of work-
ing medium around terminals and from the surface, damaged jacket by rubbing
against metal frame, damaged outer braid of low-pressure hoses).
In case of a failure of the pump or if the engine is in standstill, steering ability
is preserved, however, the steering wheel shall be manipulated with much
higher effort. It is possible to drive with the tractor to the nearest repair shop
at reduced speed.
The steering wheel shall not be hold in any side limit position for a longer pe-
riod (max. 20 sec), otherwise this causes excessive warming of oil in the hy-
drostatic steering circuit.
