1-3. Removal Procedure
Tighten the following screws to the tightening torques as described below.
Tightening torque:
. M1.7 (+) screw: 0.15 ?0.01 N.m
. M2 (+) screw: 0.19 ?0.02 N.m
. B1.7 x 6 (+) tapping screw: 0.20 ?0.02 N.m
. P2 x 8 (+) tapping screw: 0.20 ?0.02 N.m
When using the torque driver with the unit representation of cN.m, calculate the value as follows.
Example: 0.8 N.m = 80 cN.m
