STALL
FORCE
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,
gate system, Bodily Injury or Death.
The Stall Force adjustment controls the amount of force the operator
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 operator 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
flat head screwdriver. Adjust the sensitivity to the point where the gate
operates without obstructing from its own weight or the wind conditions
in your area.
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.
NOTE:
The stall force setting must at the lowest (minimum) possible
position.
Close control box, unless you are adding additional accessories
If adding additional accessories, see next page.
Turn the “AUTO CLOSE TIME” arrow in the center of the
potentiometer with small flat head screwdriver to determine how
long the gate will remain open before it automatically closes. The
limits are OFF and 3 - 120 seconds. The factory setting is OFF.
SETTING DUAL SENSE DETECTION & AUTO CLOSE TIMER
For safety reason the Dual Sense Stall Force setting on the Mighty Mule control
board comes from the factory set at set at the 10 o’clock position. 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.
CAUTION

Accessory Wires
(Photo beams, keypad, etc.)
Mighty Mule strongly recommends the use of additional obstruction detection devices. However, we do not
endorse any specific brand names. Only use products that are listed to be in compliance with any applicable UL
safety standards and national and regional codes.
PLEASE NOTE: Contact sensors, non-contact sensors, shadow loops, etc. are not included with the Mighty
Mule. Refer to the sensor manufacturer’s instructions for information about installing accessory devices.
The Mighty Mule ONLY accepts accessory devices with normally open dry contact outputs.
Make sure the operator power switch is turned OFF before connecting ANY
device wiring to the terminals of the controller. Unplugging the transformer
does not turn power to the operator off.
WARNING
With the Control Panel OFF, remove control panel cover by unscrewing
center cover fastener.
