BLEEDING THE HYDROSTATIC
STEERING HYDRAULIC CIRCUIT
1 - Start the engine and let it run at idle
speed for approx. 1 minute.
2 - At idle speed turn the steering
wheel several times to both sides.
3 - At maximum engine speed, turn the
steering wheel alternatively slowly
and quickly up to the wheel limiting
stops at both sides 3 times.
4 - Stop the engine and lower the
tractor to the front wheels.
During all the bleeding operations
of the hydrostatic steering, moni-
tor the oil level in the tank to avoid
infiltration of air into the steering
system.
Concluded the bleeding, check the oil for
proper level and replenish it if necessary
to the mark of the inspection dipstick.
Check all the joints and lines for tight-
ness.
