Step 3

 

– Your machine comes with the knives adjusted to White Flyer Clays. 

However, clay sizes can vary by manufacturer.  
Check the height / clearance of the knife-edges by placing a clay in the carousel.  
Rotate the carousel so that the clay starts to pass underneath the inner and outer 
knife separator blades. The clay must pass freely under the knife separator 
blades without binding but with the minimum of clearance. Adjust if necessary, 
with 7/16” open ended wrench. The height on both the inner and outer knife edge 
will need to be adjusted. Photos below show adjustment with carousel fitted, but 
you can remove the carousel to make adjustment easier if preferred.  
 

        

 

 

Step 4

 

– Now, you can lay out the battery terminals and control box at the back 

of the machine.  DO NOT CONNECT BATTERY AT THIS POINT.

 

 

 

Step 5

 

– Check that the ON/OFF/DISARM toggle switch on the grey control box 

in the OFF position. Connect the terminals from the wire harness to the battery.  
A fully charged good quality deep cycle marine battery is recommended.  It is 
imperative that the 

Red Wire

 goes to positive (+) and 

Black Wire

 goes to 

negative (-) on the battery.  Never hammer the terminals onto the post of the 
battery and do not over tighten the terminals. 
 

Step 6

 

– Visually check, from the rear of the machine, that the motion of the 

Throwing Arm is not restricted or blocked in any way.
