Clean the bag after using by carefully removing it from the machine and shaking the dirt on a newspaper.

Once a month the machine should be cleaned by taking off the bag, lifting the machine from the carpet and allowing the machine to run for a couple of minutes.

SEWING MACHINE

Follow directions supplied with the machine as to oiling and proper size of needle, thread, etc.  Do not make any adjustments unless you are sure you know how.  These adjustments require patience, as the adjusting screws must be turned a very little at a time to note the effect produced.  Do not run the machine at too high a speed as this will shorten its life.

When putting a motor on a foot-power machine be sure that the old machine is not over-speeded.

If your machine is provided with a foot release be sure that the release entirely cuts off current, otherwise the motor will run very hot.

FLAT IRON

There are several makes of electric irons which do excellent work and have a long life.  The standard sizes are 3, 6 and 8 pounds.  The 6-pound iron is best adapted for general household use.

If the iron becomes too hot, disconnect the lead from the iron.  In case the terminals become corroded, rub them with a piece of fine emery cloth to remove corrosion.  If the contacts become corroded or bent they should be replaced.

ELECTRIC LAMPS

Mazda lamps are the most efficient lamps obtainable and their use is recommended for all classes of service.  Your electric bills depend upon the watts per lamp and the number of hours of use.  Note in the following table that the Mazda lamps give on the average two and one-half times as much light for the same cost as the Gem carbon lamps.  The column “Cost of current per month” gives the cost of burning one lamp one hour per day for one month at the maximum rate of nine cents per K. W. H.

RESIDENTIAL LIGHTING

In most cases the following recommendations of Mazda lamp sizes will be found most satisfactory in the home.  Frosted lamps are recommended wherever the direct rays of the lamp may strike the eye, as the frosting diffuses the light.
