IF THESE SOLUTIONS DO NOT SOLVE THE PROBLEM, CONTACT YOUR AUTHORISED SERVICE DEALER.
NOTE: The carburettor adjustment needle(s) are equipped
with plastic cap(s) which prevent anticlockwise rotation from
the original factory adjustment. If your unit exhibits specific
performance problem(s) where the Trouble Shooting Section
recommends an anticlockwise needle adjustment and no
adjustments have been made since original purchase,
the unit should be taken to a factory-authorised service
dealer for repair. In most cases, the needed adjustment is
a simple task for the factory-trained service representative.
