other mechanical product. It will and does require maintenance, in proportion to the amount of use it is given.

Regular, thoughtful maintenance from the time the machine is first put into operation Will save many dollars in expensive repairs later. Not only that, but it will give you a more attractive machine throughout its lifetime and will help you avoid those expensive breakdowns just when you need the machine the most.

Again, reference is made to the instruction sheet that came with the machine. Study this carefully and note particularly the recommendations of the manufacturer as far as maintenance is concerned.

So that we will have a better idea of what we are up against on this, let us look at one of the average popular machines on the market and see just what parts may require attention from time to time.

First, take the cabinet of the machine. We find that it is constructed of stainless steel, Monel, chrome-plated steel and glass. To preserve the finish on these, a regular cleaning program must be institutedenot semi-weekly or weekly, but daily. See that the machine is cleaned and polished thoroughly every night after your operations are finished for the day. In the operation of the machine, you are using oil and salt as raw materials and this combination when coming in contact with metal has a tendency to set up a corrosive action; so to assure long life for the materials the machine must be kept clean.

In the cabinet also we find two mica heating elements under the corn pan, controlled by a two-heat switch. The purpose of these elements, of course, is to keep the corn pan at the correct temperature to properly heat the popped corn. No maintenance of the elements is required, although eventually it may be necessary to replace them or possibly replace the switch. Failure of the elements can be determined by lack of heat on the corn pan.

At the top of the machine the only electrical feature is the lighting arrangement. No maintenance here except for replacing light bulbs as they burn out.

The entire popping unit is being shown separately, in order to list the various parts for your convenience.

(1) Motor housing-Inside the motor housing we find the gear head motor (D). From the cut-away View, we can see the arrangement of the drive gears. Since the drive gear is of brass and the gear housing is sealed, with the proper amount of grease no maintenance is required unless there should be a failure that would necessitate the dismantling of this sealed housing. No grease should have to be added for many years.

The motor itself, however, should be oiled at regular intervals, approximately every three months, depending of course on the actual number of hours it is in operation,

Also, on the front of the motor housing, we find the various control switches ekettle, motor, lights and warmer. Back of these, within the housing, is located the electrical terminal block (E) from where the main power supply is distributed to the various outlets throughout the machine. The main thing here is to see that all connections are tight and that if it should be necessary to disconnect any of the wires, to see that they are replaced exactly as they were removed.

One caution is to keep the wires as free as possible from a collection of grease and dirt.

From the motor housing are suspended the hanger arms (C) from which the kettle is supported. In removing the kettle, or in servicing the machine, care should be taken to see that these are not sprung or thrown out of line in any way; for if this should happen, the kettle would not be supported in the proper position to align the spur gears on the agitator shafts.

(2) Kettle AssemblyeThe agitator spur gears should be lightly lubricated occasionally with a solid heat resistant grease (very little is required). The important factor here is to see that the needle bearing on top of the lower spur gear is kept free from hardened grease and dirt. This must turn freely to permit the proper engaging of the gears.

The kettle, completely dismantled, is also shown. As you will see, there are four distinct sections to thisethe kettle agitator assembly, kettle casting, kettle element, and the outer kettle shell. No maintenance is required for these. Eventually it will be necessary to replace the element. This is simply done by re moving the two thumb screws and two hex-head bolts and disconnecting the element Wires from the element terminals. The new kettle element can be installed and the entire unit reassembled with little difficulty. One caution, however, is to use care in handling this asscsmbly so that the themostat is not damaged in any way. This themorstat is a fragile mechanism and must be handled with care.

One of the prime factors on the kettle assembly is to keep it clean. If the operator ofpthe machine will keep the kettle lids and kettle shell wiped off occasionally during the popping process, it will not be a difficult job to give it a thorough cleaning at night. However, if the grease
