Chapter 4 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)   0.167 
N·m (1.7 kgf·cm) 
  M2.5 (2.5mm)   
0.392 N·m(4.0 kgf·cm) for Hinge support 
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). 
 
Grip Color 
Some screws have a colored grip area to help you determine the length of the screw. 
  Even numbered length screws:  Brown 
G r ip   a r e a
  Odd numbered length screws:  White 
  Special length screw:  Blue 
“Special length screw” means screws whose length is indicated in an integral number to the 
first decimal places such as 2.5 mm, 2.8 mm and so on.
