•
Check the exhaust system, the rubber mounts and the springs.

Check air filter condition and attachments.
•
Check oil level in the reduction gear box, topping up when necessary.
•
Check fan belt tension for air-cooled engine.

excessively during turning on the ground or in cross-winds. Fill to 40 Bar using a special
hand-pump where required (or see your dealer).
