a. The torque limiter is slipping:
In order to protect the driveline in the event of a blockage of the roller or the seed distri-
butor, a torque limiter has been fitted to the floating sprocket wheel. If, due to frequent
overload, this torque limiter has often slipped, wear will have occurred on the friction plates,
lowering the limit value for slipping. Tighten the torque limiter. Consult your authorised ELIET
Service center for more information.
b. Insufficient chain tension:
If the spring of the automatic chain tensioner is broken or has snapped off, the chain will
come loose. As a result, the sprocket on the traction roller will not be driven or will be driven
intermittently. Check the chain and the tension. (read § 11.8.2; page 95)
c. Broken chain:
In extreme cases, a chain may have broken or the chain lock may have come loose. Check the
chain and have it repaired or replaced by your authorised ELIET Service Center.
d. Loose sprocket wheel:
The sprocket wheel on the axle of the traction roller may have come loose. As a result, the
key may have come loose and the drive will no longer be transferred. Check the sprocket
wheel and key. If necessary, replace the key and/or sprocket wheel.
e. Insufficient activation of transmission box:
The transmission box is activated via a cable connected to the traction lever. If this cable is
stretched, the transmission will not be fully engaged and the drive will malfunction. Check
that the lever on the transmission box is fully engaged when the traction lever is pressed.
Adjust as needed.
f. Defective transmission box:
If, when the traction is activated correctly, the output axle of the transmission box does not
rotate, there is probably a defect in the transmission box. Visit your approved ELIET Service
Center to check and repair this.
g. Freewheel bearing jammed:
If, when the traction is correctly activated, the output axle of the transmission box rotates
but the torque limiter does not rotate, the freewheel bearing in the core of this torque limiter
will be jammed by dried lubricant. Pump some grease into the grease nipple to loosen the
freewheel bearing. If this does not work, contact your authorised ELIET Service Center to
clean the freewheel bearing.
h. Soiling of the cable:
The transmission is operated by the traction lever which, via a cable, controls the lever of
the transmission box. If the cable no longer slides smoothly back and forth in the cable guide
due to soiling, the cable cannot spring back sufficiently when the traction lever is released,
meaning that the drive is not completely disengaged. This can create an unsafe situation.
Clean and lubricate the cable guide.
