MM260 Installation Instructions

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. After
cleaning, apply a high quality silicon spray to a soft dry cloth and wipe the push/pull tube. DO NOT directly spray the tube!
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 potentially 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.
