DISASSEMBLING
Note: • Flywheel can be easily removed without holding the piston.
• Do not remove Spark plug as compressed air resistance has to be used for the disassembling.
• Plug cap with Plug cap spring has to be removed from Spark plug to prevent Engine from running. (Fig. 29)
(1) Turn M8 Flange nut in the center of Flywheel counterclockwise using Cordless impact driver with 13mm Socket bit.
