Page 9: Lift Identification Data
LIFT IDENTIFICATION DATA Lift identification data are indicated on the plate positioned on the control unit and under the runways. Each plate carries identification elements and some technical data; besides manufacturer’s data, the plate also includes: Mod. - Model V - Supply voltage in Volt; A - Current absorption in Ampere;...
Page 10 impair the stability and thus the intrinsic safety of the lifting device. For the same reason, load differences between the two runways must not exceed 10% of lift maximum load capacity. example: left hand runway 1800 Kg, right hand runway 2700 kg. IMPORTANT: for correct, safe use of the equipment, users must ensure a lighting level of at least 300 lux in the place of use.
Page 11: General Safety Regulations
GENERAL SAFETY REGULATIONS This equipment is for professional use only. WARNING Only one operator may work with the equipment at a time. The lift must only be used by specifically trained and authorized staff. Any tampering with or modification of the equipment not authorized in advance by the manufacturer relieves the latter from any responsibility for damage deriving from or due to such procedures.
Page 12: Lifting And Handling
LIFTING AND HANDLING When loading / unloading or transporting the equipment to the customer, it is necessary to ensure the adequacy of the vehicles and loading vehicles (e.g. cranes, trucks, etc.) and the lifting equipment used. It is also necessary to ensure that the components are lifted and transported without the risk of falling, taking into account the size, weight, center of gravity of the package and delicate parts not to be damaged.
Page 13: Installation Area
checking that there are no visibly damaged parts (control unit, lift structure). In case of damage, do not use the equipment (the lift) and contact professionally qualified staff (your dealer). The packaging materials (plastic bags, expanded polystyrene, nails, screws, pieces of wood, etc.) must not be left within reach of children since they are potential sources of danger.
Page 14: Installation
Environmental working conditions Relative humidity: 30% to 95% without condensation. Temperature range: 0°C to 40°C. INSTALLATION After unpacking, position the parts ready for assembly. During handling, necessary to find the right positioning of the lift on the ground, suitable slings or chains must be used (fig. 6). Once the exact position of the lift has been established, position the control unit.
Page 15 Anchor Fitting Procedure The lift must be fixed to the floor; for this operation, the following devices are necessary: 1. Hammer drill for drilling concrete, with 0 12 mm bit. 16 FISCHER expansion plugs for heavy fixing duty, type FH II 12/50 H (or equivalent models).
Page 16: Hazardous Areas
HAZARDOUS AREAS Before using the lift, make sure that no unauthorized persons are present within the hazardous area delimited by the yellow stripe (Fig. 7_1). Persons shall by no means stop or pass within the hazardous area delimited by the yellow stripe (Fig.7_1).
Page 17: Hydraulic Connection
HYDRAULIC CONNECTION Proceed as follows to connect the lift hydraulically to the control unit: Remove the control unit door by loosening the 4 fixing screws. Remove the protective cover. Extract the hydraulic pipes positioned inside the control unit. Extract the hydraulic pipes under the main lift runways.

LIFT TABLE HYDRAULIC SYSTEM CONNECTION Proceed as follows to connect the lift hydraulically to the control unit: Remove the control unit door by loosening the 4 fixing screws Remove the protective cover Extract the hydraulic pipes positioned inside the control unit. Extract the hydraulic pipes under the main lift runways.
Page 19: Pneumatic Connection
PNEUMATIC CONNECTION The pneumatic network to which the lift pneumatic system is to be connected must be equipped with a service unit consisting of a filter, regulator and lubricator unit (FRL). FRL units may be ordered from the manufacturer if required. To connect the lift pneumatically to the control unit, proceed as follows: Remove the control unit door by loosening the 4 fixing screws.

ELECTRICAL CONNECTION The electrical system connection procedure consists on the following steps: Connection to the mains Connection of the lighting system (if any). Connection to the mains WARNING must be carried All the operations required for machine electrical connection to the mains out exclusively by qualified personnel.
Page 21: Safety Device Specifications
SAFETY DEVICE SPECIFICATIONS The lift is provided with safety devices granting the user maximum safety in the event of failure. The safety devices are the following: Mechanical device: this device is essentially composed of a claw and a rack (see fig. 11), and immediately stops the sudden downstroke of the lift (within 100 mm height) in the event of hydraulic line failure or a blow-out in the circuit.
Page 22 Electronic aligner (fig.13): this device consists of 2 position transducers (potentiometers) and the electronic control board. The electronic control board reads the signals from the two position transducers to constantly check whether the misalignment of the two runways has reached or exceeded 50 mm;...

Page 24 The individual functions of each control on the panel are described below. MAIN SWITCH Simply turn the main switch clockwise to switch on the control unit (from 0 to 1). The switch may be padlocked in position "0" to prevent unauthorized use of the lift. MAIN LIFT SAFE PARKING BUTTON if the button is pressed directly, the lift begins to descend but without raising the pawls of the mechanical safety devices, and the built-in lift table will remain held on the mechanical...
Page 25: Commissioning
COMMISSIONING WARNING The lift must be commissioned by specially trained staff capable of ensuring that the lift and all its mechanical and electrical safety systems are operating correctly. The instructions to be followed are provided at the end of this manual, in a section for the use of authorized commissioning staff only.
Page 26 To ensure the machine remains in good working order and operates correctly, it is essential to follow the instructions given below, carrying out cleaning and routine maintenance every 1000 working hours. Routine cleaning and maintenance operations must be carried out in accordance with the instructions given below: Cleaning and maintenance operations must be carried out in conditions of maximum safety, setting the lift in a mechanically safe position.
Page 27: Lift Usage
LIFT USAGE The lift must be used by authorized personnel only. Remember that any use by staff not familiar with the procedures specified in this manual might cause dangers. Machine operation is as follows: MAIN LIFT Positioning the vehicle: after positioning the vehicle on the runway of the lift be sure that the wheels are as centered as possible on the center line of the runways, then block the parking brake of the vehicle to avoid dangerous movements.
Page 28: Manual Emergency Movement
MANUAL EMERGENCY MOVEMENT The lift has two emergency modes: MAIN LIFT MANUAL EMERGENCY BUILT-IN LIFT TABLE MANUAL EMERGENCY (for version with LT only) These two modes are intended for handling emergency situations which may arise due to malfunction, incorrect loading, power failure, etc... The purpose is to enable the operator to lower the runways of the lift in order to allow for the removal of the vehicle.
Page 29 MAIN LIFT MANUAL EMERGENCY MOVEMENT Turn off the main switch Open the control unit door Remove any obstacles under the lift Open the pawls relative to the solenoid valves A and B at the same time taking care to lower the runways with small movements. Carry out the point [4] several times making sure that the lift moves down smoothly and with the runways aligned until they rest on the ground.
