• Adjustment Procedure
The tension adjuster is located on one end of the shaft (see the dimension
drawing in this manual). The spring operating tension is factory set, but may
require adjustment on site, especially if the length of the operating rod is
changed. Correct operation should be checked and the spring tension should
be adjusted if necessary.
• If the switch operating position is higher than the desired level, lower the
adjuster a litte.
• If the switch operating position is lower than the desired level, raise the
adjuster a little.
