•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.
