e) Adjusting the friction clutch
The friction clutch protects the gears against overload (e.g. on non-slip surfaces).
In addition, adjusting the friction clutch correctly prevents the vehicle from overturning due to the motor's high torque.
The manufacturer has configured the optimal setting, therefore you do not normally need to make any
changes.
Driving frequently at full speed on a non-slip surfaces may wear down the surface of the friction clutch. If this occurs,
you may need to recalibrate the clutch. Professional drivers can adjust the friction clutch to make the vehicle respond
differently on a particular surface.
To adjust the clutch, proceed as follows:
Remove the dust cover (A) by unscrewing the 3 screws.
The friction clutch can be adjusted by turning the hex nut
(B).
Turn the hex nut clockwise to increase the drive power
to the gearbox, or anticlockwise to decrease the power
transmission.
If the friction clutch is too tight, the maximum
drive power will be transmitted and the clutch
will not function. This may damage the differ-
ential and the vehicle may overturn on non-slip
surfaces due to the high torque from the motor.
If the friction clutch is too "soft", this places
significant wear on the friction clutch. It also
affects acceleration and may prevent the vehi
-
cle from moving (due to spinning of the friction
clutch).
Adjust the clutch in small steps (max. 1/4 turn)
and check how the vehicle responds. Make a
note of each change so that you can revert to
the previous setting if necessary.
