Attention: Do not lift the machine when the cutter head is in a right up standing position ánd the mower is in full
offset position.
(the P.T.O. shaft will swing under the 3-point bow).
Before operating the machine you must check if the P.T.O. shaft does not touch the 3-point bow in any offset
position. If necessary you must install an extension shaft on the tractor P.T.O. shaft
Remark : Using an oversized tractor it is recommended to install a overload clutch.
This overload clutch should be adjusted at 850 Nm (7.500 inlb)
1.4.5 Gearbox
To protect oil to drain, the breather is replaced by a plastic plug during transport from the manufacturer to the farmer. Before
taking the machine in service the plastic plug must be replaced by the breather. During transport the breather is fixed to the
drive shaft of the gearbox.
1.4.6 Transport
During road-transport the machine is carried by the tractor 3-point linkage.
It is not allowed to carry the machine in offset position during road-transport!

1.7 Gearbox
Before operating the machine and further at regular intervals (at least every 50 hours), the following points should be
checked:
-
Oil level:
this is correct when the oil just reaches the hole of the oil level plug (green
arow).
- Breather:
should be free of obstruction. The cap must be slightly compressible. Clean
by blowing through from the inside(red arow).
Renew oil after the first 20 working hours and further after every 100 working hours, but at least once a season.
To renew the gearbox oil handle as follows:
Remove the breather and the drain plug and drain the oil.
***
Collect the old oil, e.g. in a bucket, for environment friendly disposal
.
***
Refit the oil drain-plug and pour 1 liter (± 1/2 gallon) diesel-oil through the breather hole in the housings. Clean the internal
gearbox (by washing with the diesel oil) by turning the V-belt pulley a few times by hand.
Then drain and collect the dirty diesel-oil and refill the gearbox to the required oil-level and refit the breather.
Fill up only to the proper level and use always the same oil.
Recommended is synthetic gear-oil EP-320.
