Step D q STEP D-05 Motor Installation • When setting the gear mesh, leave a small amount of backlash for proper function. Too much backlash will cause failure, so be sure to check the mesh at different points in the rotation of the Idler Gear. • Make sure to tighten motor clamp screws properly to ensure the motor plate does not spin under heavy loads and compromise the gear mesh.

Step H q STEP H-01 Painting the Body Painting: Prepare the Polycarbonate Body for painting by washing it thoroughly (inside and out) with warm water and liquid detergent. Dry the Body with a clean, soft cloth. Use the supplied Window Masks to cover the windows from the inside. A high-quality masking tape should be used on the inside of the Body to mask off any stripes, panels, or designs that you wish to paint on the Body. Use acrylic lacquer or other paints recommended for polycarbonate.
