Follow the instructions described below in advance before repairing:
• Wear gloves.
• Attach the blade cover to the blade.
• When the engine is hot from use, cool down the engine enough or you can get burned.
• Remove remaining fuel from Fuel tank and Carburetor completely. [FLAMMABLE MATERIAL KEEP FIRE AWAY]
• Remove Spark plug cap from Spark plug.
• Repair the engine on a stable workbench and in a clean workplace kept as free of dust and debris as possible.
• In order to avoid wrong reassembly, draw or write down where and how the parts are assembled, and what are the parts.
It is also recommended to have boxes ready to keep disassembled parts by group.
• Handle the disassembled parts carefully. Clean and wash them properly.
• If some bolts and screws are too tight, use an impact driver.
• Tighten the bolts and the screws to the specified torque as shown in "[4]-15. Tightening torque specifications".
• Each time after you mounted a main part of the engine such as the piston, check if it moves smoothly
without abnormal noise by manually turning the crankshaft.
• After completion of reassembly, check for loose parts or abnormal noise and vibration by manually turning the crankshaft.
