e) Adjusting the friction clutch

In addition, adjusting the friction clutch correctly prevents the vehicle from overturning due to the brushless engine's
high torque.

However, very frequent start-ups with full power on a surface with good grip can cause the slip clutch linings to wear
off over time, whereby an adjustment of the slip clutch may possibly be required. Furthermore, professional operators

To adjust the clutch, proceed as follows:
Pull out the two clips (A), then remove the dust cover (B).

Turnthehexnutclockwise(whenviewedfromtherearofthe

clockwise to decrease the power transmission.
If the friction clutch is too tight, the maximum drive
power will be transmitted and the clutch will not func-
tion.
This may damage the differential and the vehicle
may overturn on non-slip surfaces due to the high
torque from the brushless engine.

cant wear on the friction clutch. It also affects ac-
celeration and may prevent the vehicle from moving
(due to spinning of the friction clutch).
Adjust the clutch in very 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.
