Ensure your magazine is fully seated within the loader.
Slide feed rail over ammo tray (boxed ammo) or insert each round into the feed rail (loose ammo).*
Fully depress plunger to load magazine.*
*Repeat steps 2-3 until magazine is fully loaded.
Your new ACEM should arrive with break-in oil preapplied. As the loader is broken in, it will load more easily. Reapply oil as needed to reduce friction during the break-in period by applying a few drops of your favorite gun oil inside the loader to the surfaces specified in the diagram shown.
While uncommon, due to the design of certain magazine followers, it may be difficult to start the loading process with some magazines using the ACEM. When loading these magazines, manually load the first round into the magazine before inserting the magazine into the loader.
The order in which rounds are loaded can affect resistance during the loading operation. For the best results, load at least 10 rounds for the final depression of the plunger. For magazines with a capacity of less than 10 rounds, simply load the appropriate number of rounds in one operation.
When loading .40 S&W cartridges, load 5 rounds at time as the loader breaks-in.
DO NOT LOAD MAGAZINES BEYOND CAPACITY. Due to the speed of the ACEM loader, it is possible to exceed the round capacity of your magazine. Only insert the appropriate number of rounds according to the magazine manufacturer. If it is difficult to load additional rounds into your magazine and you have not reached the magazine round capacity DO NOT FORCE ADDITIONAL ROUNDS INTO THE MAGAZINE; some magazines will improperly stack the rounds when rapidly reloaded To prevent this, simply slow down the rate at which the plunger is depressed during the loading operation.
Your new ACEM is designed to automatically center the magazine upon insertion into the loader. Before inserting rounds into the loader, visually inspect the magazine alignment. Ensure the magazine is fully seated into the loader to properly utilize the alignment feature.
Ensure the magazine is fully seated into the loader during the loading process. As rounds are inserted into the magazine, the loading force will push the magazine out of the loader unless the magazine is prevented from doing so.
