ALWAYS KEEP SAFETY AT THE TOP OF YOUR LIST WHEN ADJUSTING OR
SERVICING YOUR AUTOMATIC GATE OPENER!
IMPORTANT: For safety reasons the obstruc-
tion setting or Stall Force on the Mighty Mule®
352 control board comes from the factory set at
MIN (minimum). In many gate installations this
setting will need to be adjusted to overcome the
weight and size of the gates.
The Stall Force potentiometer on the con-
trol board operates like a volume control on a
radio. It controls the obstruction sensitivity (or
the amount of force the opener will apply to an
obstruction) before it automatically stops and
reverses direction for approximately two (2)
seconds.
Use a small slotted screwdriver to turn the arrow
in the center of the potentiometer. Adjust the
sensitivity from the MINIMUM position 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.
Setting Auto-Close Time
MASTER ARM CONTROL BOARD ONLY
CLOSE TIME (auto close timer): Determines how long
the gate will remain open before it automatically closes.
The limits are OFF to 120 seconds. The factory setting
is the OFF position.
Note: Gate will NOT automatically close unless both
gates are at the fully open position regardless of the
auto-close timer setting.
