Figure 24 50-Hour Maintenance 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 to Figure 27: 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 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. CAUTION! The D-shaped shim washer must be positioned with its flat edge toward the shaft tube. 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 cylinder fins. n Remove 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 25. 26024 Gearcase Shaft Tube Gearcase Clamp Screw Gearcase Index Screw Flexible Shaft Flat (toward tube) 23052 D-shaped Shim Washer Figure 28 New Grease Old Grease 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. Shaft Tube Liner Figure 27 Output Shaft Collar Blade 23054 Bolt Guard Holder A Shaft Bolt Holder B Figure 25 . Use a hooked wire to extract the fuel filter from inside the fuel tank. See Figure 23. . 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. Nut 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. Gearcase Protector (P/N 72958-16210) Figure 29 26047 Hooked Wire Filter Element Figure 26 135-Hour Maintenance Every 135 hours of operation, remove and clean the muffler. WARNING! Never operate the machine with a damaged or missing muffler or spark arrester! Operating with missing or damaged exhaust components is a fire hazard and could also damage your hearing. 1. Remove the spark plug boot. 2. Remove the two 4 mm engine cover screws (located at the top of the recoil housing). 3. Loosen the 5 mm engine top cover screw (the screw is captive) and lift the cover from the engine. 4. Remove the two 5 mm muffler screws. Remove the lower muffler screw, then lift the muffler assembly from the engine. 5. Remove the rear muffler shield socket head screw and, while noting the orientation of parts, separate the muffler shield. See Figure 30. 6. Remove the spark arrester screen and clean with a stiff bristle brush. 7. Gently tap the muffler on a wood surface to dislodge any loose carbon. 8. Inspect the cylinder exhaust port for carbon buildup. IMPORTANT! If you note excessive carbon buildup, consult with an authorized servicing dealer. 9. Reassemble the muffler in the reverse order of disassembly.

Clean external parts thoroughly and apply a light coating of oil to all metal surfaces. . Drain all the fuel from the fuel tank. IMPORTANT! All stored fuels should be stabilized with a fuel stabilizer such as STA-BIL™, if oil with fuel stabilizer is not used. . Remove the spark plug and pour about 1/4 ounce of 2-cycle mixing oil into the cylinder through the spark plug hole. Slowly pull the recoil starter 2 or 3 times so oil will evenly coat the interior of t...
