Using the MasterLock 1178D is simple. First, set your own 4 - digit combination. You don't need a reset tool to do this. Just turn the dials to your preferred numbers. When locking, place the shackle through the item you want to secure and snap it shut. To unlock, turn the dials to your set combination. Remember, this padlock is designed for commercial and industrial use, so don't use it in situations where it's not suitable. When it comes to maintenance, keep it clean. The shackle seal and dial dust cover help protect the internal parts, but it's still a good idea to wipe it down occasionally. Also, try to keep it away from extreme moisture as the solid brass body, while corrosion - resistant, can be affected over time if exposed to too much dampness.
