Use this guide in conjunction with the instruction manual located in the machine or online at 

www.laurelmetal.com

.  The pictures and parts number identifications in the manual will be 

used here. 

When calling Laurel for help (888-528-7358) we will need the machine model #, serial # and 

manufacture date which is on a decal inside the cabinet, on the left side near the bottom.  

Normal Operation: 

The scrolling, red LED display has different styles of display: 

1. If all the selections are programmed for the same price the LED display will scroll 

Pay

$1.00   Insert Coins  

(price amount may vary according to your settings)

2. If you have different prices for your products the LED display will scroll  

Insert Coins

3. If there is a credit card swiper installed the display will scroll  

Insert Coins or Credit Card

The vend price of any selection button can be viewed by simply pressing the PUSH button on 

the switch pad (#899-20) at any time, the price will appear on the LED display for 2 seconds and 

then return to normal scrolling. 

A quarter inserted in the machine will have an audible ‘beep’ and register 

$0.25 

on the LED 

display. Additional quarters will add upwards on the display.  All quarters will pass down into 

the coin cup (#899-B19) and be held in the cup until there is successful operation of the column 

vend motor (#899-A42) which drops the shelf to vend the product. At that point then the coin 

cup motor runs to drop the quarters down into the coin box below. 

Underpay & Overpay: 

The machine is designed for exact pay and does not make change, this enables a much simpler 

design with less complex parts to maintain.  For example, if 1 quarter is inserted and a selection 

button is pushed for a $0.50 item the coin cup will run and return the quarter to the customer 

since it is an underpayment.  

For overpayment the coin cup will also run and return the inserted coins to the customer if too 

much money is inserted for the column button pushed.  Also, if the highest price set for the 

machine  is  $1.00, for example, and a customer inserts more than $1.00 then the coin cup 

automatically runs to return all coins to the customer, thus not allowing an overpayment.  

There is an option in the circuit board programming to allow overpayments, this is discussed 

further down in the section titled 

Optional Programming Modes.
