11.3.5 Belt tension adjustment
The operation lever on the handlebar can be used to set depth as well as to engage the blade.
You must ensure that the belt is not tensioned in the highest position. The blade must be disen-
gaged in the highest setting.
The second position is a transition setting. Any tension put on the belt here is insufficient to be
effective.
The actual working positions begin from the third setting. When going from the second to the
third setting, the resistance can clearly by felt on the operation lever and it is quite obvious that
the belt is tightening. If you cannot feel this tension, the tension must be reset (§11.4.2 Tightening
the belt)
How to proceed?
• Switch the engine off and remove the spark-plug cover.
Put the depth regulator in its penultimate setting.
Use you finger to press the centre of the belt.
This should move the belt by a maximum of 1 cm. If the movement exceeds this, the belt needs
tightening.
Pull the Beta pin (1) out and take the screw (2) out of the holder.
Turn the screw in a clockwise direction to tension the belt.
Now place the screw back in the holder and replace the Beta pin.
Check
Once the connector has been replaced and fixed in place and the lever is put into the third posi-
tion, you can check whether the tension is sufficient: hold the belt fast with one hand and try to
turn the blade with the other hand. If this is not possible, the tension is sufficient.
Replacing the belt
If the belt has to be replaced, the protection guards and the protection plates must be removed.

Caution:
When adjusting the belt tension the engine must be turned off and the spark
plug cap removed.
