FEELER ARM AND SPRING-LOADED ARM
Some shredder models (TS, TS-P, TRX, and TUF) can be equipped with a side arm which allows
making the mincing of material even in uncomfortable areas during work, such as inter-lines
grounds.
Side arms can be of two types:
- feeler arm, equipped with a side rod which makes the arm return (through hydraulic movement)
even after the crash with obstacles not too big (i.e. shrubs, shoots, etc);
- spring-loaded arm, without the side rod, but equipped with a simple return spring which makes
the arm return (through mechanical movement) only after the crash with bigger object (i.e. stakes,
stocks, etc);
Arm activation and deactivation
To set in action both feeler and spring-loaded
arms use lever C (picture 16):
- Place it in position A to set the arm
hydraulic system in action;
- Place it in position B to deactivate the
arm hydraulic system.
Adjustment of the arm’s sensibility to the
ground (feeler and spring-loaded arm)
The arm’s sensibility to the ground can be
adjusted through spring A (picture 17) which
acts on tie rod B:
- tightening tie rod B the arm’s sensibility to
the ground grows up;
- loosening tie rod B the arm’s sensibility to the
ground decreases;
Adjustment of the feeler arm working
amplitude
To adjust the feeler arm working amplitude
radium (picture 18):
- Extract support B;
- Adjust the length of screw A considering
that the shorter the screw’s length the
greater the rod’s radium amplitude (thus
increasing the working amplitude);
- After adjustment, insert support B back.
