Turn dial at least 4 turns left stopping on the first number 30

Turn dial right passing second number twice, stop on number next time around 40

Turn dial left past third number, stop on number next time around 50

Changing to a new combination for a 3 wheel combination lock

Select 3 new numbers to make up the new combination. Do not use numbers between 0 –20 for the last number and do not use rising and falling sequence of numbers.

With the door open throw the bolts out and lock, then dial the existing combination against the changing index mark approx 10am (not opening index mark 12 noon) and stop when the last number aligns exactly with the changing index. Hold the dial in this position and insert the change key in the keyhole at the back of the lock.

Turn the key one quarter turn anti clockwise.

Dial the new number to the same change key index making sure all numbers are entered correctly with the final number still on the change index.

Turn the change key one quarter turn clockwise and remove it.

Before closing the door try the new combination several times using the opening index mark not the changing index mark. If this does not work the back must be removed from the lock and the wheel pack realigned. If you are not confident ask us to do this for you.
