MM272 Installation Instructions

III. After Installation

  1.   Attach  the 

warning signs

 (included) to each side 

of the gate to alert the public of automatic gate 

operation. It is your responsibility to post warning 

signs on both sides of your gate. If any of these 

signs or warning decals becomes damaged,  

illegible, or missing, replace them immediately.  

Contact NSC for free replacements.

  2.  The gate is automatic and could move at any 

time, posing serious risk of entrapment. No one 

should be in contact with the gate when it is  

moving or stationary.

  3.  Do not attempt to drive into the gate area while 

the gate is moving; wait until the gate comes to a 

complete stop. 

  4.  Do not attempt to “beat the gate” while the gate is 

closing. This is extremely dangerous.

  5.  Do not allow children or pets near your gate. 

Never let children operate or play with gate 

controls.

 Keep the remote control away from 

children and unauthorized users; store controls 

where children and unauthorized users do not 

have access to them.

  6.  

KEEP GATE SYSTEMS MAINTAINED.

Always turn power to operator OFF before  

performing any maintenance. See 

page 26

 for 

maintenance procedures.

  7.  To operate this equipment safely, YOU must 

know how to disconnect the operator for manual 

gate operation (see 

page iii

). If you have read the 

instructions and still do not understand how to 

disconnect the operator, contact the Mighty Mule 

Service Department.

  8.  Disconnect the operator 

ONLY

 when the power 

is 

TURNED OFF

 and the gate is 

NOT

 moving.

    9.  Make arrangements with local fire and law  

enforcement for emergency access.

  10.  Distribute and discuss copies of the  

IMPORTANT SAFETY INFORMATION

section of this manual with all persons  

authorized to use your gate.

  11. 

 IMPORTANT: Save these safety instructions. 

Make sure everyone who is using or will be 

around the gate and gate operator are aware 

of the dangers associated with automated gate 

systems. In the event you sell the property 

with the gate operator or sell the gate operator, 

provide a copy of these safety instructions to 

the new owner.  

Should you need a replacement manual, a copy 

can be obtained by downloading one from the 

Mighty Mule web site (

www.mightymule.com

), 

by contacting NSC by calling 1-800-543-4283 

and requesting a duplicate copy. One will be 

provided to you.
