Maintenance
Schedule / Medeco Locks
The following Maintenance recommendations
apply to all Knox Rapid Entry products having Medeco locks, including
padlocks, key boxes, and key operated key switches.
The Medeco line of locks being the
precision and quality product, they require a minimal amount of attention
to maintain reliability. The following is recommended as a schedule
of maintenance:
6 Months - Spray
lock mechanism with key lube or LPS-1, operate lock twice to check
operation and spread lubricant.
1 Year Mark - Repeat
six month lubricant routine, as well as, looking for any chips or
nicks in powder coat. These should be painted over to avoid spread
of corrosion.
Emergency procedure for opening box should lock
fail to function due to grit or surface corrosion:
Spray lock cylinder generously with
a good carburator cleaner or Gumout, Poxylube or LPS-1. This product
will thoroughly clean lock mechanism and dissolve any grit that may
be holding up a pin from properly falling. Take key and work in and
out of lock a few times. Repeat Gumout procedure. Next, send a strong
vibration through the lock core to free the stuck pin. This can be
done by using any metal tool, wrench, hammer, etc. Place a piece of
wood against the lock core, then send the vibration with one of the
above-mentioned tools.
The carburator cleaner will dissipate,
leaving no residue. Follow up with routine maintenance every year
at a minimum, more so if it appears to be a problem with grit at the
particular instlallation site.
Maintenance of Door Gasket
When servicing the Medeco lock in
the Call Box, it is also recommended that the door gasket be serviced
by applying a light coat of grease-like silicone paste (Dow Corning
#4 or equal) to the gasket surface. This will keep the gasket from
freezing to the box and also add extra moisture resistance.
