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

CONNECTING ADDITIONAL DEVICES

ON/OFF Switch

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.
