Tightening Note:

When tightening any of the screws shaded in the table below, slowly turn it counterclockwise (in the direction to loosen the screw) with your hand until you feel that the screw is a little dropped in the hole. Then, slightly turn it clockwise (in the direction to tighten the screw) with your hand and tighten it according to the specified torque with a screwdriver.

Note:

For verifying the shape of each screw, refer to “APPENDIX 4 SCREW CATALOGUE”.
