LIFT UP GLASS
IMPORTANT!
READ BEFORE RAISING FRONT GLASS :
HEX SCREWS ALONG CLAMSHELL MAY HAVE
LOOSENED DURING SHIPPING!! RETIGHTEN ALL
CLAMSHELL SCREWS BEFORE OPENING GLASS!
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.
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".
2. Increase the height to 12", and raise and lower the
glass 6 more times.
3. Finally, raise the glass to it's full extension. This should
release any settled lubricant in the cylinders, and
prevent any stress on the front glass. (1)(3)
RE-ADJUSTMENT After Initial STARTUP
In addition to verifying that the Allen screws on the lift-up
glass are tightened when the case is delivered, recheck
the Allen screws on the glass ONCE THE CASE IS
IN FULL OPERATION AND BROUGHT TO
TEMPERATURE.
Temperature changes can affect the size and shape of the
materials involved, and cas cause changes in the secure fit
of the glass and the clamp.
