MAINTENANCE
The lock Promix-SM213 is lubricated by the manufacturer and does not need additional
lubrication or any special maintenance. However, if dust or dirt penetrated inside the lock during
service, and the lock began to show malfunction, then dismantle the lock, unstick the protective
film carefully from the slot in the body. Wash the lock immersing it in white spirit or petroleum
solvent with the catch downwards, to a depth of the thinned portion of the body (not deeper!).
Dry the lock and make sure that its operability has restored. Lubricate inner walls of the body
and slot ends through the slots, without sinking the catch; use a water-resistant, antifriction plastic
grease (e.g., SHRUS).
