INSPECTION Inspect the entire 

blower and tubes for damage, includ-

ing loose or missing components, and 

repair as necessary.

■

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.
