NoTE:
If your unit exhibits specific performance problem(s) where the Troubleshooting section recommends a clockwise screw
adjustment on the carburetor and no adjustments have been made since original purchase, the unit should be taken to
an authorised service centre for repair. In most cases, the needed adjustment is a simple task for the trained service
representative.
