Here is a Sentry Supreme (the numbeer 72 is the assumed to be the last number) model 5310 with locked door. To manipulate it you start with a pointer clamped to opening handle. Then you tape a piece of paper to door so that it is centered when you try turning handle to open.
Turn the dial so you are in one of the false gate areas. A light pressure on handle is all that is needed. Now make a mark on the paper as your reference point. To find the drive wheel gate all you need to do is go around and look for the opening that swings about 6 numbers. All the false gates will only go 3 numbers.
Now keep going into each false gate while watching pointer position until the pointer goes in deeper and is to the left. That is one of the opening numbers. Let us assume that the number obtained is 72. We will now find the first number. Turn the dial to the left at least 3 times and stop at zero. Turn right to 72. Check pointer. Turn left to 2 and right to 72. Check pointer. Turn left to 6 and right to 72. Check pointer. Keep adding 4 until pointer goes more to the left. That will be first number.Look at second picture of pointer. It is to the left of the mark telling me I have a gate.
Now let us assume the first number is 45. Turn left 3 times to 45. Then turn right past 45 to 43 and turn left to 72. Try handle. Turn right to 41 and left to 72. try handle. Turn right to 39 and left to 72. One time the wheels will be aligned and door will open. This whole procedure takes about 10 minutes after you have it in your head. Also note on bottom hinge the serial number if combination has never been changed.
The opening sequence for this container is left 3 times to first number. Then right pass the first number and stop at second number. Then left to third number and turn handle.
Hope this helps the new people that have little experience with these.
