The valve controls must be operated in a gradual way. Do not force the manoeuvre when the ram is in its end of stroke positions
(fully open or fully closed). The maximum operating pressure is 150 bar.

4.4.3 USEFUL TIPS

Here are a few useful suggestions on how to resolve some of the problems that may occur during work.
Cut plants shredded too much
▪ Slightly lift the cutter from the ground, adjusting the height with the wheels (the blades of the cutter must not touch the
ground).
▪ Increase the ground speed.
Cut plants not shredded enough
▪ Slightly lower the machine towards the ground.
▪ Reduce the ground speed.
Do not work in soil that is too wet.
▪
▪ Make sure that the speed of the tractor's PTO is correct and at full rate (540 or 1000 rpm, depending on the model)
Rotor clogged
▪ Soil too wet to work.
▪ Raise the machine from the ground.
▪ Reduce the ground speed.
▪ Do not work where the grass is too tall. If necessary, remove any material that has built up at the sides of the rotor to pre-
vent overheating.
The machine jolts over the ground or vibrates
▪ Foreign bodies locked between the knives.
▪ Worn or broken knives.
▪ Rotor misshapen owing to blows from foreign bodies received during work.
Other faults
The machine fails to work evenly along its width, shredding either too much or too little on one side, for example on the
▪
right: shorten the right link.
Work on hilly ground
It is advisable to proceed «upwards» in the direction of the slope. Particular attention should be paid since, owing to the nature of
the ground, the stability of the tractor could be compromised or it could slip sideways.
Winter periods
It is inadvisable to work with the machine during cold periods, when the temperature drops below 0°C (zero degrees centigrade),
because the tines become sensibly more fragile. Moreover, when the weather is cold, the machine must be allowed to idle for a
few minutes with the PTO at half rate so as to allow the lubricants and transmission components to warm up.

4.5 TOOLS

The hammers/knives with which the machine is equipped are suitable for work with soil/plants of normal conformation. Check
their condition each day to make sure they are not worn. If they should accidentally bend (or break) during work, they must be
immediately replaced and mounted in the identical position.
Proceed in the following way to replace the tools:
▪ Park the tractor on a flat surface with the machine hitched, then raise the machine with the power lift
▪ Insert two strong bearing stands at the sides of the machine to protect yourself should it fall
▪ Lower the machine on to the stands, turn off the tractor engine and apply the parking brake
▪ The hammers or tines must always be replaced in diametrically opposite pairs in order to keep the rotor in a balanced con-
dition

Tool replacement (hammers or tines) is a dangerous operation.
