Operations and maintenance
Like any other mechanical structure with moving parts, frames/doors need some maintenance to keep them in perfect working order throughout their service life. The maintenance requirement depends on factors like the opening frequency, loadings, the environment and the quality of maintenance.Maintenance consists of: inspection, lubrication, cleaning and adjustment if necessary.
Steel frames and their accessories should be inspected at regular intervals depending on the maintenance requirement, but at least once a year. Check for:
1. The gap between the door and the frame must be the same all the way around. The door must be easy to close. If necessary adjust the frame using the frame screws. Tighten any loose installation screws.
2. The sealing strip must be securely attached and undamaged. Replace if necessary.
3. The hinge and its fixing to the frame must be undamaged. Replace damaged or worn hinges with new ones. Tighten loose screws. If necessary, lubricate by following the instructions below. Check that all hinges are carrying weight. If necessary adjust the pins. Use a Torx 15 screwdriver for stepless height adjustable hinges or washers for hinges with washer adjustment.
4. Adjustment of striker. If the door is loose, set the adjusting lip for the right closing pressure. Also check the adjusting lips for locks and espagnolettes. Tighten any loose screws.
5. Check other accessories and fittings as recommended by the manufacturer.
Water-free mineral lubricant or synthetic grease must be used to lubricate hinges.
ASSA hinge grease has been tested and is specifically recommended for pin hinges. Oil must not be used unless there is no way to apply grease. It is important to use the correct grease because the surface pressure exerted in pin hinges especially can be very high.
Our frame hinges are delivered unlubricated, as are door hinges if we have surface treated them. Lubrication must be done by the installers on site.
Powder coated parts can be cleaned with most cleaning agents available on the market.
However, solvents such as white spirit, thinner, etc. must not be used. Damaged powder coated surfaces can be touched up with liquid paint. Lightly sand the damaged area with fine grade sandpaper before applying the paint with a paint pad or similar tool.
Stainless steel products can be cleaned in the same way as painted products. If a part is difficult to clean, you can use a cleaning agent called Avesta Cleaner 401. See also: www.avestafinishing.se.
As a rule, cleaning agents must not contain chlorides or abrasives which might damage the metal surface. Small scratches can be removed with a fine grade polishing cloth.
