The supply of compressed air for knotter cleaning is provided through a compressor (1)
mounted between the drawbar beams (1) (except for balers equipped with pneumatic brakes)
Note
On balers with pneumatic brakes the pneumatic connection of the tractor undertakes the filling
of the compressed air reservoir for the knotter cleaning.
The compressor is driven via a V-belt pulley (3) mounted on the flywheel and a V-belt (2). The
tension on the V-belt can be changed by moving the compressor in the oblong holes (5).
The oil level in the compressor must be checked daily prior to use by means of the dipstick (4).
Top up with oil (engine oil SAE 20) if necessary. The specification of the oil that is required is
listed in the "Technical data".
Note
The suction air filter (6) must be cleaned at least once a day or several times a day in case of
high dust load. For heavy accumulations of dirt in the filter, the aspiration port (7) can be placed
directly on the cabin roof of the tractor using a retrofit kit (order no. 287 363).
