2. Checking friction limiter settings
Torque calibration is provided by the pressure of the
spring-washers on the friction disks.
- The collar (1) is used as a reference for calibrating the
limiter correctly.
- Tighten the bolts (2), until the flange (3) is in contact
with the collar (1) without blocking it:
• Tighten the bolts (2) until the collar is blocked, then
unscrew them by a quarter turn.
- The collar must not be blocked or deformed by
excessive tightening of the bolts.
Do not over-tighten the bolts because the
limiter function could be compromised.
Do not change the calibration: risk of
damaging the machine, cardan drive and
tractor.
Friction may raise the temperature, do not
touch them.
To prevent the risk of fire, do not bring
inflammable products into the area around
the friction and avoid prolonged sliding.
