The top cylinders, which allow the raising and lowering
of the glass, have been carefully tested for proper ten-
sion. 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.
After installing new cylinders, it is advisable to perform
these three easy steps before completely raising the
front glass.
1. Slowly raise and lower each glass section 6 times, to
a height of 6".
