CAUTION! |
Make sure you do not pierce the fuel line with the end of the hooked wire. The line is delicate and can be dam- aged easily.
■Inspect the filter element for signs of contamination from debris. A contami- nated fuel filter should be replaced with a new Shindaiwa replacement element. Before reinstalling the filter, inspect the condition of the fuel line. If you note damage or deterioration, the blower should be removed from service until it can be inspected by a Shindaiwa- trained service technician.
■COOLING SYSTEM Use a wood or plastic scraper and a soft brush to remove dirt and debris from the cylin- der fins and crankcase.
