ADJUSTING THE GRILLE LENGTH
Step 1: Loosen the spring
NOTE
If several holding tongs are available, the procedure can be carried out more
quickly by processing all the springs at the same time.
• Mesure the length of the frame on which the grille is to be placed.
• Adapt the holding tongs to the spring diameter.
• Separate the blades which are located in the exceeding part of the grille.
• Fasten the spring with the holding tongs.
Step 2: Remove the components
• Unscrew the screw.
• Remove the screw, the spacers and the desired blades.
NOTE
Do not dispose of the first blade removed! This is the only one
provided with a counterbore and will be inserted again at the
end of the process.
Step 3: Adjust the length
• Cut off the protruding part of the spring.
Step 4: Insertion
• Insert the removed blade and make sure that the counterbore points to the
outside.
• Insert the lag screws and tighten them.
• Loosen the holding pliers.
Step 6: Repeat the procedure for the other springs
• Repeat the procedure for the other springs (if a simultaneous processing was
not possible).
• If the tension between the springs must be increased, the lag screw can be ad-
justed at the end of the process.
