Upper roller springs
Tightening the cutting adjustment belt
The upper roller springs of your Forage Chopper
machine is equipped with an articulation system with
side springs to facilitate the entrance of the material
easier, this is to guarantee uniform and precision
cutting. If the machine displays problems in the
entrance of materials, check the pressure of the
springs. Proceed as follows in order to increase the
spring pressure.
Keep the belts tight enough. The tightness must be enough to avoid slippage of the belt.
Remember, loose belts slip and wear out prematurely. On the hand, excessively tight belts
overload the transmission components, and this can damage them. Parched or damaged
belts must be replaced immediately.
1- After the machine is turned off, remove the belt protective cover (fig.61).
2- Remove the 4 screws C, fastening the transmission gearbox.
3- Stretch the belt(s) by tightening the stretcher screw.
4- Retighten the 4 screws C and replace the belt protective cover.
Pull the pin up to another position
Important!
Replace flaccid or damaged springs immediately.
