Mighty Mule FM350 - Manual (Page 5)

IMPORTANT SAFETY INSTRUCTIONS
Because automatic gate openers produce high levels of force, consumers need to know the potential
hazards associated with improperly designed, installed, and maintained automated gate opener
systems. Keep in mind that the gate opener is just one component of the total gate operating system.
Each component must work in unison to provide the consumer with convenience, security, and safety.
This manual contains various safety precautions and warnings for the consumer. Because there are
many possible applications of the gate opener, the safety precautions and warnings contained in this
manual cannot be completely exhaustive in nature. They do, however, provide an overview of the
safe design, installation, and use of this product. CAREFULLY READ AND FOLLOW ALL SAFETY
PRECAUTIONS, WARNINGS, AND INSTALLATION INSTRUCTIONS TO ENSURE THE SAFE
SYSTEM DESIGN, INSTALLATION, AND USE OF THIS PRODUCT.
Precautions and warnings in this manual are identified with this warning symbol. The symbol
identifies conditions that can result in damage to the opener or its components, serious injury, or
death.
Because automatic gate openers are only part of the total gate operating system, it is the
responsibility of the consumer to ensure that the total system is safe for its intended use.

How To Manually Open and Close the Gate:
CAUTION: The gate can be opened and closed manually when the opener is disconnected.
ONLY disconnect the opener when the opener power switch is OFF and the gate is NOT moving.
Because the Mighty Mule gate opener is battery powered, disconnect the opener ONLY when the
power switch on the control box is turned OFF. Unplugging the transformer does not turn power to the
opener OFF.
Disconnecting the Opener
1. Turn opener power switch (Control Box) OFF.
2. Remove hairpin clip, clevis pin, and bushing
from the front mounting point.
3. Remove the opener from the mount
NOTE: Substitute a Pin Lock [FM133] for the clevis pin on
the front mount of the gate opener to prevent unauthorized
removal of the opener from the gate.
