Troubleshooting Guide
●
Monthly, test the obstruction and entrapment protection systems.
●
Monthly, service the gate operator (make sure the power switch is OFF). Clean extended operator arm with a soft,
dry clean cloth.
●
On all gates weighing 250 lb. or more, routinely grease the ball bearing hinges at least 4 times a year; more
frequently if the gates are near a coastal area.
●
Monthly, turn off the power switch and disconnect the Mighty Mule and move the gate to make sure the gate is
moving freely without sticking or binding. Lubricate the hinges or repair the gate as required before reattaching
the Mighty Mule.
●
Monthly, check the gate system for potential entrapments from new landscaping or construction. Eliminate or
guard as required.
●
Monthly, check that the warning signs are mounted on each side of the gate and clearly visible. Replace the signs
if they are missing or damaged.
●
Replace batteries every 2-3 years and properly recycle old batteries.
If your gate operator does not function properly after it is installed, use this guide before calling the Nortek
Security & Control Service Department.
