4.2 TORQUE LIST FOR BOLTS AND NUTS
Unless otherwise specified, tighten the metric bolts and nuts to the torque shown
in the table below.
The tightening torque is determined by the width across flats (b) of the nut and
bolt.
NOTICE
When tightening panels or other parts with tightening fixtures made of
plastic, be careful not to use excessive tightening torque. Tightening
excessively will damage the plastic parts.
Be extremely careful when tightening.
