Thanks to Owner-Manuals.com! This manual was exactly what I needed. As Amana was purchased by Maytag and later by Whirlpool, there was no way to receive it from their websites. I was lucky to find this resource.
A comprehensive Operating and Service Manual. All schematics are complete and easy to read. The PCB drawings and complete parts list are very helpful. I would definitely recommend this manual.

USING THE TURNSPIT
1. Place the food on the spit (A) and secure it using the two forks (B), making sure that it is well balanced to avoid excessive strain on the turnspit (C) motor. 2. Put the two spit supports into the holes (F) of the tray. 3. Then put the tray into the 1st level from the bottom fitting the square end of the spit into the motor axis (E). Remove the spit handle (G). We suggest that you pour some water into the bottom of the tray to reduce smoke and splashes of fat. Start the turnspit turning the oven/grill control knob to symbol . Leave the oven door open during cooking and fit the heat shield to protect the control buttons against excessive heat.
