6 SAFETY NORMS SAFETY NORMS GR2_3_4_5 Strictly conform to the norms reported by the plates DE2499B (fig. 1) or DE4236 (fig. 1a) placed next to the controls, in order to avoid possible accidents while operating the crane. Only authorized persons are allowed to operate the crane. The crane must be used on firm, level ground. Check that the vehicle hand brake is on and that the wheels are chocked.
7 WARNING AND INSTRUCTIONS 7.1 Generality SAFETY NORMS GRU FASSI 7 The use of the crane is reserved to authorized personnel, instructed in advance, who has to conform to the safety norms and instructions contained in the use manual supplied with the crane. (See norms ISO 9926-1) It is absolutely prohibited to walk or stop under a suspended load It is prohibited for unauthorized persons to be within the working area. Under no circumstances interfere with the safety and protection devices.
(!) ATTENTION (!) Avoid swinging the load above working and transit areas; any hidden danger situation must be audibly alarmed. Avoid all those situations which may result in crushing during vehicle stabilization, crane movement and load handling.
(!) ATTENTION (!) Respect the safety distances from electric lines; the minimum distance is, according to CEN norms, five (5) meters, except for otherwise prescribed by national norms. (!) ATTENTION (!) Failure to respect the minimum safe distances may result in electrical hazards for the operator and his assistants. ELECTRICUTION: General safety precautions for the operator and potential co-workers. If the crane hits an overhead power line, do not touch the crane, the truck or the load.
Do not rotate the crane before the load is lifted. WARNING AND INSTRUCTIONS GRU FASSI Do not operate with sudden movements, activate the controls with slow and progressive movements; rotate slowly and with care paying attention to the stability of the vehicle. With vertical lift, on hydraulic and mechanical extension, rotate slowly in order to avoid side-skidding. (!) ATTENTION (!) Do not utilize the crane for pushpull (F), lateral (F) or sideways (F) operations.
7.5 Residual risks NOTE: This reasoned list does not carry the complete list of the residual risks, which are examined more in detail paragraph by paragraph in the manual under "(!) ATTENTION (!)"; it is instead a way to exemplify to the operator the types of hazards linked to the use of the crane, which basically involves a lifted load in movement.
Wrong manoeuvring: the crane can fall break or overturn if the operator performs a wrong manoeuvre due to the lack of familiarity with the operation procedures (see manual of use and maintenance) or due to inadequate psychophysical conditions: we remind you that the directives in force impose a suitable training of the personnel before using these types of machines and require an adequate psychophysical condition to operate safely a lifting device that always implies the intrinsic danger of a lifted load.

13 13.1 MANOEUVRES AND CONTROLS TO STABILIZE THE VEHICLE SUPPLEMENTARY BEAMS GRU FASSI Generality The outriggers rams prevent damaging stresses both to the frame and to the vehicle suspensions on which the crane is mounted to and assure the stability of the unit during load handling. (!) ATTENTION (!) Be very careful when stabilizing the vehicle; make sure that no one is or transits in close proximity of the working area of the outriggers.
13.2 Manual extension and re-entry of the outrigger supports SUPPLEMENTARY BEAMS GR2_60»65 13.2 (!) ATTENTION (!) To manoeuvre the supports hands must only grab the handles placed on the outrigger rams. - Disengage the locking devices of the outrigger supports by putting the levers of the devices A and B from the position of the fig. 8 to the one of the 8a. Pull, extending from the base the outrigger support.
(!) ATTENTION (!) The engaging of the outriggers lock B and B1 ensures the complete extension of the outrigger support (essential for the stability of the complete crane vehicle unit) and the impossibility of accidental movement. SUPPLEMENTARY BEAMS GR2_60»65 13.4 (!) ATTENTION (!) The complete extension of the outrigger supports is visually indicated by the yellow triangles which are found at the end of the beam and of the first support (fig.
13.4 Controls to stabilize the vehicle SUPPLEMENTARY BEAMS GR2_60»65 13.4 (!) ATTENTION (!) When controlling from the opposite side of the vehicle (it is not possible visually to check the operation) it is compulsory make sure that no one is or transits in close proximity to the outriggers. - Manual extension of the outrigger supports: See Paragraph 13.2 or 13.3.
14 CONTROLS TO OPERATE THE CRANE CONTROLS TO OPERATE THE CRANE GR2_3_4 14.1 Generality (!) WARNING (!) Before operating the crane it is compulsory to set the outriggers. (Plate DE6723 fig. 14) The crane and hydraulic implements can be manually operated with: ground controls on both sides or, on request ground controls on both sides and top seat controls by hand-cables; top seat controls.

14.6 Indicator of inner boom horizontal position (on request) CONTROLS TO OPERATE THE CRANE GR2_60»65_3_4 The column is fitted with a device that informs the driver through a sound/light signal in the cab, that the inner boom max position allowed during transport on road has been exceeded. 14.7 Stand-up control station This special fitting allows the operator to use the crane controls whilst standing in a higher position, in order to have good vision of the working area.
The instruction plate DE5643 reported on the selector, identifies the intervention sectors of the device (fig. 16). The operator's presence in the stand-up control station allows only a reduced rotation of the crane, since it is not enabled to pass on the station. When the operator is not present in the stand-up control station, the crane is allowed to operate at its max rotation arc (which may differ from 180° indicated on plate DE5643).
15 15.1 (!) MANOEUVRES OF THE CRANE LOADS (version with load limiting device) Generality Before manoeuvering the load, verify that the working area is suitable for your crane. The lifting curves of the capacity plate indicate the maximum load that the crane can lift at a certain radius and at a certain height. To utilize the maximum capacity of the crane, it is necessary to position the inner boom as indicated on the capacity plate.
16 16.1 (!) MANOEUVRES OF THE CRANE LOADS (version with lifting moment limiting device) Generality Before manoeuvering the load, verify that the working area is suitable for your crane. The lifting curves of the capacity plate indicate the maximum load that the crane can lift at a certain radius and at a certain height. To utilize the maximum capacity of the crane, it is necessary to position the inner boom as indicated on the capacity plate.
16.2 "Electronic" lifting moment limiting device CONTROLS TO OPERATE THE CRANE GR2_45»65_3_4_SE This device utilises an electro-hydraulic system managed by an electronic logic that prevents any operation tending to cause an increase in the pressure induced by the load in the lifting rams (inner, outer rams of the crane and of the hydraulic extension, if fitted), up to the critical values.
If during operation the red led B comes on, the activation value of the lifting moment limiting device has been reached. CONTROLS TO OPERATE THE CRANE GR2_45»65_3_4_SE Any hidden danger situation for persons must be audibly alarmed by pressing the push button E. When there are serious, imminent and dangerous conditions for persons and things during load handling, operate on the STOP button, which isolates all crane functions.
16.4 Load handling CONTROLS TO OPERATE THE CRANE Manoeuvres of the crane Fig. 20a-b e 20c-d illustrate the configurations of the crane (and of the eventual hydraulic extension) with the manoeuvres allowed and not allowed WITH HYDRAULIC JIB by the device, in connection with the horizontal position of the crane and extension outer booms.

(!) ATTENTION (!) Activation of the exclusion device of the lifting moment limiting device. When the operator uses this device, it means that he wishes to override the lifting moment lifting device in order to make some manoeuvres (which would be impossible with the device active) that bring the moment to within the maximum level, but involve an overload condition.
If a reduction of capacity is necessary because of insufficient stability of the complete unit, new capacity plates must be fixed giving the derated capacity in accordance with the final stability test. (!) ATTENTION (!) Always check carefully that the vehicle is perfectly stable, paying special attention to the area immediately in front of the driver’s cabin as this is usually less stable. 16.
