- Page 2 2. Mount the lock in place with four X 20 attaching screws (provided). ⁄ 3. Attach the dial ring by loosely installing the attaching screws to hold the dial ring in place for alignment. The dial ring opening index should be at the 12 o’clock center position. 4.
- Page 3 8. Tighten the dial ring screws. 9. Place a flat washer, the compression spring, and another flat washer over the spindle and into the recess at the dial hub (Figure 4). Figure 4 10. Insert the dial into the lock, but remember that you should not allow the cam to slide outward against the accelerator spring, possibly damaging it.
- Page 4 15. Turn the dial at least one complete revolution in either direction, then stop at 50. The accelerator spring should now be in the loaded position. 16. Hold the lock cover in place and push the dial in at 50. The accelerator spring should not release. If the accelerator spring does release, the spindle must be turned clockwise into the cam one revolution and the lock checked again, beginning at step 13.
- Page 5 TO LOCK Turn the dial counterclockwise (left) at least five complete revolutions for maximum security. COMBINATION CHANGING FROM 50 - 0 Make up a new combination, selecting three numbers of your own choosing. Do not set the third number of the combination between 90 and 99 or 0 and 10. This area is known as the forbidden zone. Adjacent combination numbers should be at least 5 numbers apart.
- Page 6 COMBINATION CHANGING FROM A SAMPLE COMBINATION OF 50 - 25 - 50 1. Turn the dial counterclockwise, stopping when 50 is aligned with the changing index the fourth time. 2. Turn the dial clockwise, stopping when 25 is aligned with the changing index the third time. 3.
- Page 7 4. Unscrew the dial and spindle assembly from the lock. Remove the drive cam. 5. Remove the Spirolox retainer from the top of the wheel post. ® 6. Remove the wheels and associated parts. Place them in sequence so they can be re-installed in the proper order.
- Page 8 ERRORS The most frequent error in the changing procedure is dialing the number to the wrong index. Occasionally all the numbers may be dialed to the opening index rather than the changing index. More often, dialing part of the combination to the changing index and part to the opening index occurs. As long as the door is open, the error is easily corrected.
