10/15-Hour Maintenance

Clean the

spark plug and

check the gap

0.024–0.028 inchat the electrode. (0.6–0.7 mm)

Figure 19

50-Hour Maintenance

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 NGK BPMR6A or equivalent resistor type spark plug of the correct heat range. See Figure 19.

NOTE:

The NGK BPMR6A 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.

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

nRemove the cylinder cover and clean grass and dirt from the cover and cylin- der fins.

nRemove the cutting attachment, cutting attachment holder and gear shaft collar. Remove the filler plug from the side of the gearcase and press new grease into the gearcase until grease is pushed out. Use only lithium-base grease such as Shindaiwa Gear Case Lubricant or equivalent. See figure 20.

Use a hooked wire to extract the fuel filter from inside the fuel tank. See figure 21.

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.

Remove and replace the filter element. Before reinstalling the new filter ele- ment, 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.

Lubricate the Flexible Shaft.

Lack of lubrication will cause rapid wear to the flexible shaft and also to the shaft tube liner, resulting in increased vibration and greatly decreased service life. Remove and lubricate the flexible shaft as follows:

Gearcase Index

Screw

Flexible Shaft

Shaft Tube

Figure 22

1.Loosen the gearcase clamp screw.

2.Remove the gearcase index screw.

3.Slide the gearcase and shield assembly from the shaft tube.

4.Pull the flexible shaft from the shaft tube assembly, and clean the shaft thorough- ly in solvent.

5.Inspect the shaft carefully, and replace if worn or damaged. If flexible shaft is worn and needs replacement, liner should also be replaced.

6.Coat the entire length of the shaft with Shindaiwa Premium Gearcase Lube (or equivalent), and reinstall the shaft in the shaft tube assembly.

NOTE:

For extended shaft life, the flexible cable should be reversed end-for-end during the reinstallation process.

7.Insert the flexible shaft into the female end of the gearcase pinion.

8.Install the gearcase on the shaft tube in the reverse order of removal.
