50-hour Maintenance
■■Remove the shaft bolt, bolt guard, holder A, blade, holder B, and the output shaft collar. Press new grease into the gearcase until the old grease has been pushed out. Use only
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:
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 thoroughly in solvent.
5.Inspect the shaft carefully, and replace if worn or damaged. If flexi- ble shaft is worn and needs replace- ment, liner should also be replaced.
6.Coat the entire length of the shaft with a premium gearcase lube and reinstall the shaft in the shaft tube assembly.
7.Insert the flexible shaft into the female end of the gearcase pinion.
NOTE:
For extended shaft life, the flexible
cable should be reversed
8.Reinstall the gearcase onto the shaft tube assembly.
CAUTION!

WARNING!
Blades are not inter- changeable between Shindaiwa edgers and unit/brushcutter models. Operating any unit with a blade or attachment not approved for the unit can be hazardous and may cause seri- ous injury.
Inspect the Gearcase Protector
The metal gearcase protector is installed
to protect the gearcase flange from
damage when working close to side- walks or other abrasive surfaces, and should be routinely inspected for dam- age or excessive wear.
When replacing the protector, inspect to be sure that both of the protector mount-
ing screws are firmly tightened and each
screw is locked in place with a nut as shown.
