McDonalds Portion Control Timer
A common problem associated with the McDonalds style portion control timer is when one size
becomes non-adjustable. This may not be more than the trimming potentiometers being adjusted
out of the usable range. To bring them back into range, all that must be done is to turn the screw
counterclockwise 20 complete turns, and then clockwise:
Number of Complete Turns Medium Large Super-Size
Fast Fill 3 4 5
Standard Fill 5 7 9
This procedure should eliminate the replacement of many good portion control timers.
