Lock is preset to initially open at W-O-R-D-3. To set your own combination. 1. Open lock and withdraw shackle. Note: For first time use, position wheels so that W-O-R-D-3 aligns with the Master logo. 2. Pull spring-loaded metal end cap off (see diagram). 3. Remove all five combination wheels. 4. IMPORTANT: Make sure the red marks remain aligned with the Master log. Install wheels so desired combination aligns with Master logo. 5. Snap metal end cap back into place. (Note: If end cap will not mount properly, check wheels to make sure they are right side up.) To lock: Dial your new combination, close shackle; scramble wheels to lock. Be sure to record your secret combination.
