WARNING! Before performing any maintenance, repair or cleaning work on the unit, make sure the engine and cutting attachment are completely stopped. Disconnect the spark plug wire before performing service or maintenance work. WARNING! Non-standard parts may not operate properly with your unit and may cause damage and lead to personal injury. NOTE: Using non-standard replacement parts could invalidate your Shindaiwa warranty. Muffler This unit must never be operated with a faulty or missing spark arrester or muffler. Make sure the muffler is well secured and in good condition. A worn or damaged muffler is a fire hazard and may also cause hearing loss. Spark Plug Keep the spark plug and wire connections tight and clean. Fasteners Make sure nuts, bolts, and screws (except carburetor adjusting screws) are tight. WARNING! n Blades are not interchangeable between Shindaiwa edgers and trimmer/ brushcutter models. Operating any unit with a blade or attachment not approved for that unit can be hazardous and may cause serious injury. n Never repair a damaged blade by welding, straightening, or by modifying its shape. An altered blade may break during operation, resulting in serious personal injury. Daily Maintenance Prior to each work day, perform the following: n Remove dirt or debris from the engine, check the cooling fins and air cleaner for clogging and clean them as necessary. n Carefully remove any accumulation of dirt or debris from the muffler or the fuel tank. Dirt build-up in these areas could cause engine overheating, induce premature wear, or create a fire hazard. n Check for loose or missing screws or components. Make sure the cutting attachment is securely fastened. n Check the entire unit for leaking fuel or grease. 10-Hour Maintenance Every 10 hours of operation (more frequently in dusty or dirty conditions): n Remove the air cleaner element. See Figure 18. Clean or replace as necessary. To clean element: wash it thoroughly in soap and water. Let it dry before reinstalling the element. Unscrew Fastener Remove and clean or replace the element CAUTION! Do not operate the unit if the air cleaner or element is damaged, or if the element is wet. Figure 18 10/15-Hour Maintenance Every 10 to 15 hours of operation: n Remove 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. Clean the spark plug and check the gap at the electrode. 0.024–0.028 inch (0.6–0.7 mm) XST021 NOTE: The NGK BPMR6A also meets the requirements for electro magnetic compliance (EMC). Figure 19 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 Gearcase Index Screw 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 20. Flexible Shaft Shaft Tube Figure 22 New Grease Old Grease Output Shaft Collar Blade Hooked Wire Filter Element Figure 21 Shaft Bolt Bolt Guard Holder A Holder B 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 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. Figure 20 . Use a hooked wire to extract the fuel filter from inside the fuel tank. See figure 21. 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 Shi...
