Replacement Procedures Screw Tightening Torque Use the following torque when tightening screws. CAUTION: Overtightening may damage screws or parts. Undertightening may allow screws to loosen (and possibly fall out) causing a short circuit or other damage.
NOTE: To tighten screws quickly and accurately, an electric screwdriver is recommended. M2 (2mm) M2.5 (2.5mm) M2.5 (2.5mm) M3.0 (3mm) 0.167 Nm (1.7 kgfcm) 0.245 Nm(2.5 kgfcm) 0.392 Nm(4.0 kgfcm) for Hinge support 0.245 Nm (2.5 kgfcm)
NOTE: To prevent damage to THIN HEAD screws, press along the axis of the screwdriver while turning the screw. This is because the contact area between the screw and driver is less than for a pan head screw (standard pan-shaped screw head).
