Shindaiwa T242X, 81643 manual 10/15-Hour Maintenance, Every 10 to 15 hours of operation

10/15-Hour Maintenance

		Clean the
		spark plug and
0.024–0.028 inch		check the gap
	at the electrode.
(0.6–0.7 mm)

Figure 27

Every 10 to 15 hours of operation:

nRemove and clean the spark plug. Adjust the spark plug electrode gap to 0.024- 0.028 inch (0.6-0.7 mm). If the spark plug must be replaced, use only an BPMR6A or equivalent resistor type spark plug of the correct heat range. See Figure 27.

NOTE:

The BPMR6A also meets the requirements 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 frequently in dusty or dirty conditions):

nRemove and clean the cylinder cover and clean grass and dirt from the cylinder fins.

nRemove the cutting attachment, cutting attachment holder and gear shaft collar. Remove the filler plug from the side of the gear case and press new grease into the gear case until old grease is pushed out. Use only lithium-base grease such as Shindaiwa Gear Case Lubricant or equivalent. See Figure 28.

nRemove mainshaft and lubricate both ends of the splines.

nUse a hooked wire to extract the fuel filter from inside the fuel tank.

See Figure 29.

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.

Remove and replace the filter element.

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.
