Cool down engine enough, as the engine just after used may cause you to get burned.

Remove the remaining fuel in Tank and Carburetor completely.

Repair the engine on the stable workbench and in the clean workplace to prevent dust and debris from entering.

Record where and how the parts are assembled, and what are the parts. Do not reassemble them wrongly. It is recommended to prepare the several kind of boxes to keep parts group by group.

Treat the disassembled parts carefully. Clean and wash them certainly.

When some bolts and screws are difficult to loosen, use Impact driver.

Tighten the bolts and the screws to the specific torque as shown in Fig. 68.

Once the main parts are assembled, check every move and sound by manually turning each part.

Check the assembled parts by turning them manually if there is any unusual gap or sound around.
