4.5 SETTING THE METERING PLATE TO SUIT YOUR BEDDING PRODUCT AND NEEDS
Before using the machine with bedding products the metering plate must be adjusted to
provide a suitable gap in order to obtain the desired bedding flow rate.
The size of the gap will determine the rate of flow at which the bedding product flows onto
the conveyor belt and will vary in size between all bedding products and your needs. The
ideal gap will be found through fine tuning.
Follow the procedure below,
Only adjust the metering plate by means of moving the adjusting handle from left
to right.
Moving the adjusting lever to the right will reduce the hole size reducing product flow.
Moving the lever to the left will increase the hole size increasing product flow.

that this cover is left off until after you are happy with the speed and quantity of bedding
being dispensed.
The potentiometer for changing the conveyor speed has buttons to press which will alter
the speed of the conveyor belt which in turn will increase or decrease the distance of the
product being dispensed (max speed 9.9, min speed 0.1).
4.7 SETTING THE AUGER SPEED
The potentiometer for changing the conveyor speed has buttons to press which will alter
the speed of the auger which in turn will increase or decrease the amount of product being
dispensed (max speed 9.9, min speed 0.1).
