DANGER
There is stored energy built up by high
tensioned compression springs inside the
balancing device! When a coil is cut the
released tension creates a spatter of
sparks and flames.
The working area must be free of flam-
mable materials. Position the balancing
device so that the spatter will be directed
away from personnel.
Cut the coils of the springs inside the
housing as specified below:
• Outer spring: cut at least five coils!
• Middle spring: cut at least four coils!
• Inner spring: cut at least four coils!
Double-check the number of coils cut and
make sure all the tension in the springs
are removed.
