NING ION OPERATION AND MAINTENANCE IMPORTANT SAWFAETRYNIINNGSTRUCTIONS WARNING To reduce the risk of SEVERE 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 ONE 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. Replace both batteries and connect red wires to red (positive) terminals. Connect black wires to black (negative) terminals. 9. Disconnect ALL power BEFORE performing ANY maintenance. 10. ALL maintenance MUST be performed by a LiftMaster professional. 11. SAVE THESE INSTRUCTIONS. MAINTENANCE The SW425 is designed to be maintenance free. However, for optimum performance and safety, the following maintenance procedures should be taken. SENSITIVITY ADJUSTMENTS The most important thing to maintain on any gate is the safety equipment. As the gate becomes older, the amount of force necessary to move the gate will vary. When this happens, the sensitivity adjustments may need to be readjusted. Check to see whether the sensitivity may need adjustment at least once a month. Actuate the gate a few times and observe the amount of force that is needed to reverse the gate in both directions. The gate should reverse relatively easy. If it does not reverse easily or does not reverse at all, adjust the gate sensitivity (page 15). CONTROL DEVICES From time to time check to see whether all of the control devices that are connected to the operator are functioning. This is especially important of interrupt devices such as reverse loops, reverse edges, photo beams or any other device which was installed in regards to safety. GATE Having a well maintained gate will ensure that the operator runs smoothly and safely. Occasionally inspect the gate to see that it swings easily at a normal speed and is free of any obstructions. See if the hinges show any sign of rusting and grease or oil if necessary. Observe the speed of the gate and determine if the gate operator appears to be working harder than usual. 19
