ATTENTION:
FREQUENT LUBRICATION IS NECESSARY ON THE LOCKING SYSTEM
The pushbutton lock contains an “O” ring seal to protect the interior from dust and water. If this mechanism is not
lubricated regularly it will become difficult to operate and it may not return to its home position preventing the key from
operating the lock. If this happens simply pull up on the pushbutton to manually bring it back to its home position.
Lubricate the pushbutton with a light lubricant such as silicone spray. The pushbutton may have to be periodically
disassembled and cleaned.
