Special Notes:
*1. Your gate and gate hardware will require more maintenance than your HySecurity operator. A damaged gate or worn
hardware may cause slow or erratic operation and will result in excess drive wheel wear. Lubricate gate hardware more
frequently and check for smooth operation by opening the toggle clamping mechanism and then pushing the gate
manually. One person should easily be able to push all but the largest of gates. Damaged or warped gate panels should be
straightened or replaced.
*2. Normally, drive wheel life is many years. They are designed to avoid slipping on the rail. Drive wheel life may be greatly
shortened by any of these faults: clamping spring not adjusted correctly, operator or drive rail misaligned in relation to gate
panel, badly warped gate panel, extremely stiff gate hardware, and/or loose wheel mounting bolts (tighten to 25 ft. lb).
*3. Verify that the red clamping spring is compressed tightly so that drive wheels apply a strong grip on drive rail. The red
spring should be compressed to 2-inches in height.
*4. The limit switch and deceleration switch rollers should ride ¼ to ½-inch below the drive rail, near the center of the channel.
Maladjustment may result in false or early tripping or no limit function at the end of travel. Verify that the slow down limit
ramps are tightly bolted to the drive rail.
*5. The uid level should remain no less than one inch below the ller hole. Refer to maintenance instructions for uid lling.
Loss of uid is not normal and indicates a leak that must be located and repaired. Use Uniow uid, part MX000970, if
additional uid is required.
*6. Replace the Smart Touch Controller coin battery with DL 2025 / DL 2032 or CR 2025 / CR 2032.
*7. DC Operators use DC motors with 4 carbon brushes which wear in normal operation. Worn brushes can damage the DC
motor. Under severe conditions HySecurity recommends that brushes be checked after 2 years or 250,000 cycles and the
replacement interval be adjusted as necessary.
