CAUTION: If fixing bolts for counterweight are loos-
ened, consult your nearest authorized dealer.
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 stabilize
their friction coefficient.
NOTE: Tightening torque required is shown in N•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 120 N, the torque produced will be:
1 m ×120 N = 120 N•m
To produce the same torque with a wrench of 0.25 m:
0.25 m ×
N = 120 N•m
Necessary force will be:
120 N•m ÷ 0.25 m = 480 N
