3. Push the locking/unlocking shaft with firm, sharp pressure using your thumb to release any pressure on the main spring, please use caution when releasing spring.
4. With the locking shaft still depressed, wind the spindle clockwise until the follower returns to the beginning of the spiral to release the shaft.
5. Load 5 r ounds of your ammo, point-down, into the top of the drum along the largest diameter of the drum, just under the tower, loading in a clockwise direction.
6. Firmly hold the spindle to add two clicks in a clockwise direction using the small winding ke.
7. Slowly release the spindle and allow the 5 rounds to load into the tower.
8. Turn the spindle clockwise and remove 2 of the last rounds loaded and continue to turn the spindle clockwise until it returns to the end of the spiral track (starting position) and add those 2 rounds into the top of the drum in the same place you just loaded the first 5 rounds.
9. The spindle will be locked in position and you can release it and continue loading until 75 rounds are in the drum.
10. Close the cover and secure the latches.
11. Use the main winding key and turn it about 10 good turns or clicks. As you turn the key, you will hear and feel the spring as it clicks, over-winding is not recommended.
Please note if you are loading to put the drum in storage for future use, do all the loading, but only wind the main key 1 or 2 clicks to keep pressure on the loaded ammo. Save the winding till you are ready to fire.
