CLEANING A MAGAZINE
To clean a magazine, run out all the matrices into a galley and place the magazine in a convenient place for cleaning. Magazines which have the verges assembled on them should be placed with the bottom side up in order to prevent the dirt getting in around the pawls while cleaning. With a good magazine brush, clean all dirt and gum from the inside of the magazine. If the magazine is very dirty, first use a little good gasoline or denatured alcohol on the brush to cut all the gum loose. Brush the magazine and use the air until dry on the inside. Then polish the inside by applying a very small amount of graphite on the brush and rubbing briskly.
In cleaning a magazine, be sure that all the little dark spots, which show where the lugs of the matrices set in the magazine, are removed. These spots are gum which forms in the magazine, due to oil and dirt which are carried in on the lugs of the matrices. If these spots are not entirely removed it would be better not to clean the magazine at all. When they are merely loosened up by the cleaning, the matrices will be held back and will not drop regularly.
Frequently the bristles of the brush will get caught in the partitions of the magazine and pull out of the brush. These can usually be removed by dragging the edge of a soft pine yard-stick across them.
Keep the various parts of the machine, with which the matrices come in contact, clean and free from oil, and the magazine will not get dirty for some time.
