INSTRUCTIONS TO BE FOLLOWED BEFORE INSTALLING THE OPERATOR
TO ENSURE THE PERFECT INSTALLATION AND OPERATION OF THE COMBI 740 ADHERE TO THE FOLLOWING EXPLANATORY POINTS AND RELATIVE DRAWINGS.
IMPORTANT: THE ENTIRE INSTALLATION PROCESS MUST BE CARRIED OUT BY QUALIFIED, TECHNICAL PERSONNEL IN COMPLIANCE WITH EN 12453 - EN 12445
SAFETY STANDARDS, AND IN ACCORDANCE WITH MACHINERY DIRECTIVE 2006/42/CE.
CARRY OUT A CAREFUL ANALYSIS OF RISKS IN ACCORDANCE WITH SAFETY REGULATIONS IN FORCE.
GENERAL INFORMATION:
The COMBI 740 is an oil-hydraulic automated operator designed to open and close swinging gates; it is installed below ground at the
base of the gate's rotation hinges. It is an oil-hydraulic operator with a built-in hydraulic drive unit; the entire operator is housed inside
its enclosure, cemented at the base of the gate leaf. The electronic programmer control is installed externally in a protected area and
it controls all possible movement functions automatically or semi-automatically, depending on the client's requirements.
The gate opener includes a number of accessories that ensure necessary safety and manoeuvrability, making this operator suitable for
installation in any public or private place.
PRELIMINARY WARNINGS FOR SAFETY AND GOOD SYSTEM OPERATION
!
Before installing the operator in the ground, be sure to verify the following:
- Installation, checks, testing, and risk analysis and further maintenance must be carried out by qualified, authorised, technical personnel.
- This automated device was designed for specific use, as indicated in this manual, with safety, control and signalling accessories as
minimum required.
- Any use of the operator which is not explicitly stated in this manual may cause operational disruption or damage to property and people.
- Check the consistency of the soil to avoid settling or subsequent deformation in the installation area.
- Ensure that there are no utility lines in the immediate vicinity or underground which may hinder any digging required.
- Ensure that in the immediate vicinity of installation accessories, both above and below ground, there are no sources of electromagnetic
disturbance that could hide or influence magnetic/electromagnetic readings from any metal loop detectors and from all electronic
control and system management equipment.
- Ensure that the mains power and voltage to the electric motor is 230V±10% 50Hz.
- Combi 740 must be powered with electrical cables having 1mm
than 50 meters, the use of electrical cables with appropriate diameter wires is recommended.
- For any replacements of parts or accessories, use original components indicated by the manufacturer.
- All packaging materials must be disposed of by specialised companies. Do not throw away, in normal waste receptacles, any material
that may be harmful to the environment.
- Meccanica Fadini is not responsible for any damage caused by improper use, or use not specifically mentioned in this manual, and is
not liable for malfunctions resulting from the use of materials or accessories not provided by the company itself.
- The manufacturer reserves the right to make changes to this manual without prior notice.

VERSIONS OF THE COMBI 740 OIL-HYDRAULIC OPERATOR
110° Version = underground swing gate opener with 110° maximum leaf rotation.
175° Version = underground swing gate opener with 175° maximum leaf rotation.
Normal version = 110° and 175° non locking in the two movement directions. Use of an electric lock is always recommended.
Locking version = 110° and 175° locking in the two movement directionss.
Version with Brake = 110° and 175° rotation with adjustable hydraulic braking in the two movement directions, during the last 40 cm (approx.) of movement.
Version with Flow Regulator = 110° and 175° rotation with adjustment of hydraulic flow (controls the leaf speed) in the two movement directions for leafs longer than
2.5 meters.

Important: For installations with Combi 740 (Normal or Locking) with leafs longer than 2.0 meters it is always necessary to install an
Electric lock or a Leaf stop bolt: the possible solutions are shown in Pic. 5 and Pic. 6. For a single leaf, it is recommended

that the electric lock be installed horizontally.

IDEAL USE OF THE COMBI 740 BELOW GROUND OIL-HYDRAULIC OPERATOR
- Combi 740 Normal version, 110° rotation:
1) The Combi 740 110° can be used on any leaf, always with an electric lock.
2) For leafs
longer than 2.50 meters use of the Combi 740 with brake is recommended.
3) For special 4.0 and 5.0 meter leafs a Flow regulator must be installed.
4) The static weight that the Combi 740 can bear is 700Kg, for a 1.0 meter long leaf. If this
length is exceeded the weight of the leaf must be decreased (Pic.7).
- Combi 740 locking version, 110° rotation:
All previous four points apply.
5) The Combi 740
electric lock. An electric lock is always necessary for leafs that are longer than 2.0 meters.
Locking is recommended for leafs up to 2.0 meters long, without an

- Combi 740 Locking version, 175° rotation:
All previous five points apply.
INSTALLING THE ENCLOSURE
WARNINGS: ensure that the gate structure is suited to the operator and check to see
if the fixed and moving parts require any special reinforcements for installation,
making sure that there are no obstacles or friction during the entire movement of the
leaf.
The normal enclosure must be cemented to the base of the gate in order to receive
and secure the operator. However, the lower leaf hinge must be removed first because
the Combi 740 rotation shaft acts as a lower rotation hinge (Pic.8).
