Product Usage
Insert 3 D cell batteries, or plug a DC power convertor into the feeder. Align the hopper with the base to allow insertion, then twist to lock in position. Inser the bowl into the feeder base, connecting the hooks inside the base. Fill the feeder with pet food of choice, and align the lid to the hopper using the arrows. Insert the lid and twist. Food must be dog or cat food, and cannot be a treat, canned food, or moist.
Turn the feeder on using the switch on the bottom. The feeder can be scheduled to provide three meals of varying sizes per day. Each meal is adjusted with 0.25 cup increments. To set meals and schedule, hold the ENTER button for 2 seconds. Using the up and down arrows, select the meal you would like to edit with the ENTER button. This will allow you to edit the time of the meal, followed by the meal size, if changes are desired. Once all meals are edited, press ENTER and the feeder will reenter the automated feeding mode. To manually feed the pet, hold the up arrow button and the feeder will provide a meal the size of the scheduled breakfast meal.
Mechanical Function
The feeder accepts food from the hopper located above. The feeder contains four sets of fins, each connected to an axis parallel to the floor.

Design for Manufacturing and Assembly
The dog feeder is already manufactured very simply and efficiently. The part count is low and only necessary parts were manufactured. The design is very simple. Most parts are plastic and thus easily manufactured with casting or molding, which is the method chosen. The material should not be changed because plastic is the most logical choice for reasons of cost and ease of manufacturing. Any change in material would spike the price of the machine.
