Important Safety Instructions 

 

WARNING – To reduce the risk of injury or death: 

1) READ AND FOLLOW ALL INSTRUCTIONS. 
2) Never let children operate or play with gate controls. Keep the remote control away from children. 
3) Always keep people and objects away from the gate. NO PERSON SHOULD CROSS THE PATH OF 
THE MOVING GATE. 
4) Test the gate operator monthly. The gate MUST reverse on contact with a rigid object or stop when an 
object activates the non-contact sensors. After adjusting the force or the limit of travel, retest the gate 
operator. Failure to adjust and retest the gate operator properly can increase the risk of injury or death. 
5) Use the emergency release only when the gate is not moving. 
6) KEEP GATES PROPERLY MAINTAINED. Read the owner’s manual. Have a qualified service person 
make repairs to gate hardware. 
7) The entrance is for vehicles only. Pedestrians must use separate entrance. 
8) SAVE THESE INSTRUCTIONS. 

Safety Instructions for Installation 

A. Install the gate operator only when: 
1) The operator is appropriate for the construction of the gate and the usage Class of the gate, 
2) All openings of a horizontal slide gate are guarded or screened from the bottom of the gate to a minimum 
of 4 feet (1.22 m) above the ground to prevent a 2-1/4 inch (57.2 mm) diameter sphere from passing through 
the openings anywhere in the gate, and in that portion of the adjacent fence that the gate covers in the open 
position, 
3) All exposed pinch points are eliminated or guarded. 
4) Guarding is supplied for exposed rollers. 
B. The operator is intended for installation only on gates used for vehicles. Pedestrians must be supplied 
with a separate access opening. The pedestrian access opening shall be designed to promote pedestrian 
usage. Locate the gate such that persons will not come in contact with the vehicular gate during the entire 
path of travel of the vehicular gate. 
C. The gate must be installed in a location so that enough clearance is supplied between the gate and 
adjacent structures when opening and closing to reduce the risk of entrapment.   
D. The gate must be properly installed and work freely in both directions prior to the installation of the gate 
operator. Do not over-tighten the operator clutch or pressure relief valve to compensate for a damaged gate. 
E. For gate operators utilizing Type D protection: 
1) The gate operator controls must be placed so that the user has full view of the gate area when the gate is 
moving. 
2) The placard provided marked in letters at least 1/4-in (6.4-mm) high with the word 

WARNING

 and the 

following statement or the equivalent: “ Moving Gate Has the Potential of Inflicting Injury or Death – Do Not 
Start Gate Unless Path is Clear” shall be placed adjacent to the controls, 
3) An automatic closing device (such as a timer, loop sensor, or similar device) shall not be employed. 
4) No other activation device shall be connected. 
F. Controls intended for user activation must be located at least ten feet (10’) away from any moving part of 
the gate and where the user is prevented from reaching over, under, around or through the gate to operate 
the controls. Outdoor or easily accessible controls shall have a security feature to prevent unauthorized use.
