Master Safety Locks & Devices

Supplier: Tropical Safety & Identification

Every Master padlock is ruggedly built for long life and trouble-free service. With minimal care, your Master padlock will provide security and smooth operation for many years to come.


Here are a few tips that will help you keep your padlocks working efficiently:

1. Lubricate padlocks periodically with very light machine oil. Do not use graphite in any form! Your Master padlock is a precision instrument, and graphite may actually cause the mechanism to stick. Apply oil only in shackle openings. A silicone or Teflon® based lubricant is recommended for the keyway.

2. Padlocks used outdoors may require occasional cleaning. To do this, immerse them overnight in kerosene -- let them dry thoroughly – then apply oil and other lubrication where appropriate.

3. Your padlock is only as strong as the hasp on which it is hung. Use only a strong, plated hasp with concealed screws. An unplated hasp will cause rust to drip down through the shackle opening into the mechanism of your padlock.

4. If your padlock is difficult to open in freezing weather, a sharp blow will usually restore it to normal operation by dislodging ice. A Master padlock can take it!

5. When a padlock is operated infrequently or exposed to severe weather conditions, internal working parts may become tight. In these cases, it is suggested that you exert a slight downward pressure on the shackle while the key is being turned. Doing this 3 or 4 times will relieve any tension and will usually restore easy and normal operation of the padlock.

6. We suggest that you do not use WD40® on your lock because dust particles may clog the pins when WD40® is sprayed inside the lock.
