General care

Cleaning

As hinges are worn, a fine black dust is spread around the bearing. The dust also often settles on the frame and the door/window/hatch door. The best way to avoid the dust is to keep the hinges well-lubricated.

For lubrication of hinges, water-free mineral lubricant or synthetic lubricant should be used. Do not use oil unless it is absolutely impossible to apply grease. It is very important to use the right kind of lubricant, since stress especially in the case of journal-supported hinges can be very high.

Locks and Latches

If fitted correctly, these should not require any maintenance. Dead and latch bolts can sometimes fail to engage in the strike plate, which can be due to movements of the door/ frame or wear of the hinges. This can be fixed by adjusting the strike plate. Do not use oil as this attracts dirt and dust

Stainless steel should be dusted regularly with a dry cloth and occasionally washed with soap and water to maintain its appearance. Do not use abrasive materials or acid based cleaning products.

Polished Brass Fittings

These are protected with a lacquer to ensure that they reach the user in good condition. The appearance will be improved by dusting with a soft cloth or leather. Metal polishes will remove the lacquer and should not be used unless the user is prepared either for oxidation (tarnishing) to discolour the surface or they are prepared to clean regularly to maintain the polish.

Plated (Zinc, Chrome, Nickel, Brass)

These finishes should be washed with warm soapy water using a soft cloth. Do not use abrasive materials.

  • Hydraulic Door Closers close a door automatically at an adjustable speed.
  • A Door Closer is usually mounted at the top of a door or above it on the jamb.  There are also internal models that are installed hidden inside the door frame for a cleaner look.
  • An internal Spring applies force to the Arm to close the door.  Hydraulic fluid (oil) flows through pathways inside the closer.  The resistance/restriction to fluid flow determines the door closing speed.
  • Spring strength and adjustment (if any) varies by model.  Heavier doors require stronger door closers.
  • Door closers are matched to their application, based on door size and weight, and the corresponding strength needed to close them properly.
  • Adjustable Spring tension allows models so equipped to work well for doors of sizes within their range of adjustment.

Door closer is little routine maintenance to be carried out on door closing devices,lubrication generally being limited to the application of a little oil on visible joints,such as those on the arms of overhead patterns.The closer should be examined periodically to ensure that the door is closing correctly and that the appropriate valve adjustments have been made for the closing and latching speed of the door.

Panic Bar is regular inspections and maintenance is necessary in the interests of public safety.Attention must be given to opening and closing with adjustments as necessary to compensate for any door or frame movement.Floor sockets should be cleaned out to prevent foreign matter impeding bolt movement.Lubrications will be limited to the application of a little light machine oil to the pivots of the top tripper mechanism of panic bolts,and to the head of panic latches.
