Maintenance Recommendations. Periodic servicing will extend the
3.5.2.5
life of the lock and is essential for maintaining proper security. Each time
the combination is changed, inspect the lock for wear, metal filings, drilled
holes, cracks, or any other visual signs of attempts to defeat the lock by
forced entry techniques. The inspection process should include removal of the
back cover of the lock, and visual examination of each wheel part as well as
the cam and lever assembly to make sure nothing is worn or damaged. If
lubrication is required, use molybdenum-disulfide (powder). NEVER use oil- or
petroleum-based lubricants on combination locks.
Each time the back cover is removed, the combination should be
reset. Remember to check the combination at least three times before locking
the container.
Any other maintenance other than changing the combination and
inspecting the lock should be referred to a qualified locksmith.
