	Clean the spark plug
	and check the gap at
0.6–0.7 mm	the electrode.

Figure 17

Every 10 to 15 hours of operation:

nRemove and clean the spark plug. Adjust the spark plug electrode gap to 0.6 - 0.7 mm. If the spark plug must be replaced, use only an NGK CMR5H or equivalent resistor type spark plug of the correct heat range. See Figure 17.

NOTE:

The NGK CMR5H also meets the require- ments for electro magnetic compliance (EMC).

CAUTION!

Before removing the spark plug, clean the area around the plug to prevent dirt and debris from getting into the engine’s internal parts.

50-Hour Maintenance

Every 50 hours of operation (more often in dusty or extreme conditions)

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.

nUse a wire hook to extract the fuel filter from inside the fuel tank. (Figure 19). Inspect the fuel filter element. If it shows signs of contamination from debris, replace it with a genuine Shindaiwa replacement fuel filter element. Before reinstalling the filter, inspect the fuel line. If you discover damage or deterio- ration, the unit should be removed from service unitl it can be inspected by a Shindaiwa-trained service technician.
