1.
Allow the hydraulic systems of the loader and of the attachment to cool down completely before any
work on hydraulic systems.
2.
Make sure that the loader boom or any other part of the attachment can’t move causing crushing or
pinching hazards:
3.
Lower the loader boom to its lower position and lower the mower firmly on the ground. For the best
stability, keep the attachment locked on the loader.
4.
Shut down the loader engine.
5.
Move the auxiliary hydraulics control lever to its extreme positions several times to release residual
pressure.
6.
Uncouple the multiconnector or quick couplings from the loader to prevent draining of hydraulic oil.
7.6.1.1
Reversing the order of the hydraulic connections
If the direction of rotation of the
mower must be reversed, the
hydraulic hoses must be
connected in different order.
Interchange the place of the
hydraulic hoses 1 and 2, see
adjacent figure.
Tighten the hydraulic fittings
carefully with hand tools using
moderate torque. Make sure that
the routing of the hydraulic
hoses does not prevent the
reinstallation.
7.6.1.2
Tightening hydraulic fittings
Tighten the fittings carefully according to given instructions and safety procedures. Keep in mind that over
tightening will break a fitting. Tighten basic fittings carefully with hand tools using moderate torque. The elbow
fittings should be tightened at last, after hoses have been fitted to their clamps.
Tapered JIC-type fittings:
Lubricate the inner surfaces and threads of the fittings.
A JIC type fitting is not tightened only by torque and it will not need a lot of force at
any point when tightening. Overtightening or misalignment will break the fitting.
Turn the manually as far as possible, and then lightly with tools ensuring that the
fitting is threaded properly. When noticing clear increase in needed force, tighten
fitting to its final tightness by turning only 1/3 to 1/2 turns using tools.
After tightening, try to twist the hydraulic hose manually, the fitting should stay firm.
