Glass Installation/Balancing
Glass Adjustment
The top cylinders, which allow the raising and lowering of
the glass, have been carefully tested for proper tension.
However, during shipment, the lubricant inside may have
settled. This settling may cause excessive or uneven
tension on the glass - to the point of breakage. Perform
the three easy steps listed below before completely raising
the front glass.
1. Slowly raise and lower each glass section 6 times to
a height of 6 inches.
2. Increase the height to 12 inches, and raise and
lower the glass 6 more times.
3. Finally raise the glass to its full extension, and lower.
These steps should release any settled lubricant within the
cylinders and prevent any stress on the front glass.
Additionally, after installing NEW cylinders, it is
advisable to perform these three easy steps before
completely raising the front glass.
WARNING
Cylinders are a "wear" item
Glass is HEAVY and can cause bodily harm.
Cylinders are designed to:
• Support the glass when fully open
• Allow the glass to close slowly
Have your service Contractor replace
the cylinders when required
