Down Leveling Speed and Down Stop
The down leveling speed and the down stop adjustment must be performed together since
the down stop adjustment affects the down leveling speed. However, the down leveling
speed does not affect the down stop adjustment.
1. Place the controller on Inspection Operation.
2. Adjust the down stop for a positive stop.
3. Adjust the down leveling speed to 10 to 12 FPM.
4. Tighten the locknut on the down leveling speed adjustment.
5. Check the down leveling speed.
