IMPORTANT: Make sure bolt and nut threads are clean
before installing.
Apply lubricant (e. g. white zinc B solved
into spindle oil) to bolts and nuts to sta-
bilize their friction coefficient.
NOTE: Tightening torque required is shown in kgf
x
m.
For example, when tightening a bolt or nut with
a wrench of 1 m length, turning the end of it with
a force of 12 kgf, the torque produced will be:
1 m
×
12 kgf = 12 kgf
x
m
To produce the same torque with a wrench of
0.25 m:
0.25 m
×
kgf = 12 kgf
x
m
Necessary force will be:
12 kgf
x
m
÷
0.25 m = 48 kgf
