Introduction-General Rules for Maintenance Operations
(i) Using a torque wrench with extension handle
• When a torque wrench with special service
tool or extension handle is used, it indicates
that the actual torque has been excess if the
torque indication on the wrench reaches the
specified value.
• In this manual, only the torque values
requiring special explanations are
described. When such a wrench is used,
please calculate its torque value according
to the following formula.
• Formula: T’= T × L2/(L1+L2)
T’ Torque wrench reading (N•m)
01 T Actual torque (N•m)
Length of special service tool or extension handle
L1
(mm)
L2 Length of torque wrench (mm)
2. Electric control
(a) Disconnecting and connecting battery negative
cable
• Before starting an electrical maintenance
work, be sure to disconnect battery
negative (-) cable in order to prevent
burning accident caused by short circuit,
etc.
• Before disconnecting and connecting a
battery cable, be sure to turn off ignition
and lighting switches and loosen fixing
nuts of the cable completely. Never twist
and pry it.
• After the battery cable is disconnected,
records of clock and radio, etc. will be
cleared. Therefore, you should check such
facilities as clock and radio and make
corresponding records before such an
operation.
