IMPORTANT SAFETY INSTRUCTIONS
How To Manually Open and Close the Gate:
CAUTION: The gate can be opened and closed manually when the operator is disconnected. 
ONLY disconnect the operator when the operator power switch is OFF and the gate is NOT moving.
Disconnecting the Operator 
  1.  Turn operator power switch (Control Box) OFF.
  2.  Remove hairpin clip, clevis pin, and bushing from both the front and 
rear mounting points.
  3.  Remove the operator from the mount.
CAUTION: Because the LPA gate operator is battery powered, 
disconnect the operator ONLY when the power switch on the contol 
box is turned OFF. Unplugging the transformer does not turn power 
to the operator OFF.
NOTE: Substitute a Pin Lock 
  [FM133] for the clevis pin on the front 
mount of the gate operator to prevent unauthorized removal of the 
operator from the gate. 
Because automatic gate operators can produce high levels of force, consumers need to know the 
potential hazards associated with improperly designed, installed, and maintained automated gate 
operator systems. Keep in mind that the gate operator 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 operator, 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 operator or its components, serious injury, or 
death.
Because LPA automatic gate operators are only part of the total gate operating system, it is the 
responsibility of the installer/consumer to ensure that the total system is safe for its intended 
use.
