Positioning the spray guns (both units)
1. Loosen the support bar knob and slide the gun support bar
to the desired horizontal position. Make sure the gun is far
enough away from the cart so that the rear wheel does not

the 1st gun support bar. Secure in place by tightening
the 2nd gun support bar knob.
b. Loosen the 2nd gun post knob and slide the post to the
desired horizontal position.
c. Run the 2nd gun cable through the block and cable
guides, underneath the frame and back towards the cart
