MM560 Installation Instructions 28
Do not use the Dual Sense Stall Force adjustment to compensate for a gate
that is sticking or binding. Excessive Stall Force may cause damage to the
gate operator or gate system or Injury or Death.
The Stall Force adjustment controls the amount of force the opener will apply
against an obstruction before it stops and reverses direction. The adjustment
on the control board operates like a volume control on a radio. It controls the
amount of force the opener will apply to an obstruction before it automatically
reverses direction.
The Stall Force adjustment is located on the control board. Turn the “STALL
FORCE” arrow in the center of the potentiometer with small at head screw-
driver. Adjust the sensitivity from the MINIMUM position up to the point
where the gate operates without obstructing from its own weight or the wind
conditions in your area.
NOTE: You may need to increase the stall force in cold weather due to
increased resistance from gate hinges. However, the adjustment must remain
as near to minimum as possible and when the weather improves decrease the
setting to the appropriate position.
Turn the “AUTO CLOSE TIME” arrow in the center of the potenti-
ometer with small at head screwdriver. Turning the pot all the way
counter-clockwise will turn the auto close feature off. The minimum
auto close time is 3 seconds. The maximum (turn the pot all the way
clockwise) auto close time is 120 seconds.

For safety reason the Dual Sense Stall Force setting on the Mighty Mule control board comes from the factory set at
MIN (minimum). This setting may need adjustment depending on the size and weight of the gate.
ALWAYS KEEP SAFETY AT THE TOP OF YOUR LIST WHEN ADJUSTING OR SERVICING YOUR GATE SYSTEM.
