6 - MAINTENANCE
6.3 REPLACING THE BLADES OR THE HAMMERS
In order to replace the hammers it is necessary:
- To place the machine mounted on the tractor on a flat surface
-
With the lifting system of the tractor lift the machine as high as possible from the ground
-
Place adequate props under both ends of the machine
- Turn off tractor engine and pull hand-brake
-
Replace blades and tighten forcefully the bolts with the nuts that hold them (tightening torque 50Nm)
The locking of the pins holding the blades can be achieved with cotter pins or nuts, depending on the model of the
machine
Limit the tightening torque to 50Nm to tighten the nuts on the pins
6.4 LUBRICATION
Always read carefully the directions given on the containers of the products. Always keep oils
and grease out of the reach of children. Avoid any contact with your skin. After using the
products always wash carefully and thoroughly. Dispose of spent oils following the environment
protection rules in force.
The scheduled operations listed in this Manual are given by way of information only and they
refer to normal conditions of use of the implement. Therefore, it may be necessary to modify them
depending on the type of work performed, the more or less dusty environment, season factors
etc.
If the working conditions are particularly severe, it obviously becomes necessary to increase the
number of maintenance operations.
- Before you inject the lubricating grease through the grease nipples, it is necessary to carefully
clean the nipples, in order to prevent mud, dust or other foreign bodies from mixing with the
grease, which would decrease and, in some cases, even completely nullify the effect of the
lubrication
- When topping up or changing the oil, it is necessary to use the same type of oil which has been
used the previous time.
Before starting up the machine for the first time, check the level of the lubricants as described. Before checking the
levels, topping up or changing the lubricants, carefully clean the parts or the areas involved.
Before you start working with the machine, always check the oil level in the gearbox through the level indicator or by
means of the dip stick. Top up, if necessary, by pouring oil through the oil-filling cap.
Undertake the first oil change after 30 working hours and, after that, after 400 hours or, at least, once a year. This
operation must be performed in a workshop equipped with lifting means able to take the weight of the machine,
which should then be propped up with adequate supports. Discharge the oil by removing the discharge cap.
