Tilt Switch
The solid state electronic tilt switch controls the trail-back of the auger in the direction of travel around the
bin. This switch is set at the factory for normal trail-back and should stop the movement of the machine
when the bottom of a 16' auger is 14"-20" back of a vertical line from the stub shaft bearing to the floor.
The trail-back is adjusted correctly when the following is observed: The gear motor will turn “ON” when the
down augers are vertical. The gear motor will turn “OFF” when the down augers reach 6° trail-back.

Adjustment Procedure
1. In order to check the electronic tilt switch function and make trail-back adjustments, the electronic
tilt switch must have power applied to the controller.
2. The tilt switch has been factory set for proper trail-back and should stop the movement of the
machine when the bottom after 16' auger is 14"-20" back of a vertical line from the stub shaft bearing
to the floor.
3. For more trail-back, loosen the wing nut and move the tilt switch bracket to the left or to the right for
less. Do not move the bracket more than 1/16" at a time.
Failure to follow these instructions may result in injury or death.
