IMPORTANT SAFETY INFORMATION

To prevent SERIOUS INJURY or DEATH from a moving gate:
• Pinch points must be guarded at all times. Install enclosed-style gate
tracks and roller guards.
• Place screen mesh 6 feet (1.8 m) high on the gate to prevent access
through openings anywhere the gate may travel.
• Mount controls at least 6 feet (1.8 m) from the gate or ANY moving
part of the gate.
• Install Warning signs on EACH side of gate in PLAIN VIEW.
Permanently secure each Warning sign in a suitable manner using
fastening holes.
• This operator is intended for vehicular use only. To prevent INJURY
to pedestrians, a separate pedestrian access should be supplied,
visible from the gate. Locate the pedestrian access where there is not
a chance of INJURY at any point during full movement of the gate.
• Contact sensors MUST be located at the leading and trailing edges,
and post mounted both inside and outside a horizontal swing gate.
Non-contact sensors such as photoelectric sensors MUST be
mounted across the gate opening and operate during BOTH the open
and close cycles.
• To AVOID damaging gas, power or other underground utility lines,
contact underground utility locating companies BEFORE digging
more than 18 inches (46 cm) deep.

INSTALLATION TIPS

DO's
• Weld a horizontal bar across entire gate on any installation for
strength. Make sure that the operator is mounted level or it will not
function properly.
• Make sure there is slack in the operator cable.
Operator Cable
DON'Ts
• DO NOT install upside down.
• DO NOT install next to sprinklers or any area that may expose the
bottom of operator to water.
• DO NOT install on uphill or downhill gates.

INSTALLATION

!
• Entrapment protection devices MUST be installed to protect anyone
who may come near a moving gate.
• Locate entrapment protection devices to protect in BOTH the open
and close gate cycles.
• Locate entrapment protection devices to protect between moving
gate and RIGID objects, such as posts or walls.
• Too much force on gate will interfere with proper operation of safety
reversal system.
• NEVER increase force beyond minimum amount required to move
gate.
• NEVER use force adjustments to compensate for a binding or
sticking gate.
• If one control (force or travel limits) is adjusted, the other control
may also need adjustment.
• After ANY adjustments are made, the safety reversal system MUST
be tested. Gate MUST reverse on contact with a rigid object.
• ALWAYS wear protective gloves and eye protection when changing
the battery or working around the battery compartment.
• The operator can be mounted on top of the gate frame.
• The operator must be installed at least 12 inches from the ground.
• DO NOT install on ANY pedestrian passageways, doorways, or gates.
• DO NOT over-bend the operator cable. Doing this will cause the wires
to eventually break.
• DO NOT weld the crossbar on just a few pickets, or they could bend.
