Section – 3 Safety Check List
Rolling doors are large, movable objects. They move with the help of electric motors or manual operators
(chain, crank, push up, etc), and most have springs under high tension. These items and their
components can cause injury. In order to avoid injury to yourself and others, please follow the instructions
in this manual.
Review the potential hazards and preventative measures listed below:
Table 3.1 – Potential Hazards and Preventative Measures

drop-out mechanisms, adjusting wheels, etc.
•
Locate the possible pinch-points of the unit (Drive chain, coil
area, bottom bar, etc.) Do not operate the door while
someone is near these areas.
Check the following during installation and before leaving the job site:
1. If the unit has tension springs, be sure the proper amount of tension is applied to the torsion
springs, in order to properly counterbalance the weight of the curtain.
2. Securely fasten the tension adjusting wheel in place with the appropriate hardware provided.
3. Check that the keys and/or cotter pins have been set in place and fit properly at all sprockets or
gears.
4. Check that the setscrews in each sprocket or gear (one over the key and one offset from the key)
have been tightened properly.
5. Check all fasteners holding the unit to the building structures.
6. Check all fasteners used to assemble the components of the unit together.
7. Instruct owner or representative in the proper method of operating the door.
