Maintenance (continued)

50-hour Maintenance

Every 50 hours of operation (more frequently in dusty or dirty conditions):

1.Remove and clean the cylinder cover and clean dirt from the cylin- der fins.

2.Use a hooked wire to extract the fuel filter from inside the fuel tank. See

Figure 15.

CAUTION!

Make sure you do not pierce the fuel line with the end of the hooked wire. The line is delicate and can be damaged easily.

3.Remove and replace the filter ele- ment. Before reinstalling the new filter element, inspect the condition of all the fuel system components (fuel pick-up line, fuel return line, tank vent line, tank vent, fuel cap and fuel tank). If damage, splitting or deterioration is noted, the unit should be removed from service until it can be inspected or repaired by a Shindaiwa-trained service technician.

■■Combustion chamber should be decarbonized, and the valve clearance should be adjusted. It is highly recommended that this is done by a Shindaiwa-trained service technician.

■■Replace the spark plug annually: Use only the type recommended in the ”Specifications” section or an equivalent resis- tor type spark plug of the correct heat range. Set spark plug electrode gap to 0.6 mm (0.024 in).

IMPORTANT!

The valve clearance should be adjusted. It is highly recommended that this is done by a Shindaiwa-trained service technician.
