7.12 LUBRICATING THE INTERNAL GUIDES
The glass panel frames are supported on the inside by straight guides that
require periodic maintenance: the guides must be clean and adequately
lubricated.
Enter "maintenance mode" (see
"MAINTENANCE MODE").
Lower the glass panel (or both) and then cut off the power supply to the
product.
Proceed as described under "ACCESSING THE INSIDE OF THE PRODUCT".
Thoroughly clean and dry the chromed surfaces of the guides. Remove any
deposit or encrustation from the contact surface of the guide [A] and from
innermost corners. (Fig. 56)
Shift the glass support [B] occasionally and clean the parts that are now
exposed.
Only if necessary adjust the guide coupling at the end of cleaning (see
"ADJUSTING THE COUPLING").
Lubricate the guide [A] by applying an abundant and evenly spread layer of
spray grease. Move the glass panel from one end stop to the other to ensure
that the protective film is spread evenly over the guide. (Fig. 57)
Repeat this procedure if necessary. Do not, however, use the grease to
excess: should grease accumulate on the lower parts of the guide, we
recommend that all excess be removed.
The lubricant has properties of excellent adherence and viscosity, high
resistance to temperature and a very low capacity of mixing with dust or ash.
It is therefore recommended that you only use the lubricant we supply
(optional).
Other unsuitable lubricants could seriously affect correct operation of the
rise n' fall system or the frequency of maintenance.
7.13 ADJUSTING THE COUPLING
Using an Allen key if possible, turn clockwise to tighten the coupling on the
guide, thereby reducing the play that normal wear can produce. Adjust the
coupling by putting it halfway up the guide with the glass panel half open.
The coupling must only be adjusted if absolutely necessary.
Adjust by tightening the screw [A] the minimum necessary and proceeding by
steps to check that the glass panel slides properly. Raise the glass panel at
operating speed, checking for any slowing down and if there is, loosen the
screw [A] slightly.
Avoid over tightening the screw [A] on the coupling, otherwise when the
lubrication of the guide is nearly finished the coupling could lock during
movement and trigger an alarm state in the control unit.
