50-Hour Maintenance

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

n Remove the cylinder cover and clean

grass and dirt from the cover and cylin-

der fins.

n Remove the cutting attachment, cutting

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: Refer

CAUTION!

The D-shaped shim washer must be positioned with its flat edge toward the shaft tube.

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 25.

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

See Figure 23.

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.

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 and dry with a clean shop towel.

5.Inspect the flexible shaft carefully, and replace if worn or damaged.

NOTE:

Always replace the liner if the flexible shaft is being 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.

See Figure 27.

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

Inspect the Gearcase Protector.

The metal gearcase protector (P/N 72958- 16210) is installed to protect the gearcase flange from damage when working close to sidewalks or other abrasive surfaces, and should be routinely inspected for damage or excessive wear. See Figure 29.

When replacing the protector, inspect to be sure that both of the protector mounting screws are firmly tightened and each screw is locked in place with a nut as shown in Figure 29.
