1.11 Field Balancing Instructions
IMPORTANT: EVERY BARRIER IS BALANCED AT THE FACTORY BEFORE IT IS SHIPPED. IF
ANY ADDITIONS OR CHANGES ARE MADE TO THE BARRIER ARM IN THE FIELD, THE
BARRIER MAY REQUIRE RE-BALANCING. AN UNBALANCED ARM MAY DAMAGE THE
OPERATOR.
If any additions or changes are made to the barrier, the following guidelines will help you
determine what changes, if any, need to be made to the barrier balance:
1. Make the desired changes to the barrier arm.
2. Secure the tip end of the arm to prevent injury or accident.
3. Disconnect the connecting rod which runs between the upper and lower cranks,
this will free the arm to be balanced.
