Maintenance
The clutch is actuated via the clutch/safety stop lever.
The clutch is disengaged when the lever is not depressed, i.e. the engine does not propel the ma-
chine and the hydraulic drive is blocked (see fig. 37), the engine continues to run.
In order to avoid slippage of the clutch during work, the play and spring tension of the clutch
lever are adjusted in the factory (see fig. 38).
The clutch adjustment must be checked and, if necessary, re-adjusted after the first hour of op-
eration. It is adjusted using the adjusting screw on the Bowden cable in the housing (see fig.
38).
Depending on the application, the adjusting screw must be screwed in or out in order to obtain
the correct spring tension.
Secure the adjusting screw again afterwards by means of the lock nut!
Checking the clutch:
•
Switch the engine off
•
Remove the side panel on the left.
•
Measure the length of the spring
•
Depress the clutch/safety stop lever (2nd person), measure the length of the spring again.
•
The difference in length should be at least 3 - 4 mm.
•
If not, adjust it with the aid of the adjusting nut on the
Bowden cable.
•
Firmly tighten the lock nut.
•
Attach the side panel.
