USE AND MAINTENANCE LIGHT TOWER
General Safety Information Allowed use The light tower has been designed to lighten the area in which it is positioned and oriented, after installing it on a generating set foreseen for this purpose. The generator supplies the electrical feeding necessary to operate the light tower. Any other use is expressly forbidden and could generate risks to the user’s safety and damages to the product.
USE AND MAINTENENACE LIGHT TOWER Before moving the lighting tower or lifting the telescopic mast, please make sure that no power lines are in the proximity of the working area. The contact of the light tower with live electrical cables can result in serious injury to the personnel or cause immediate death by electrocution.
Technical features of the lighting tower The pneumatic telescopic mast on which the lighting system is positioned, allow to lift the lighting point to several metres from the ground. The telescopic mast is made of sections which can be manually locked. The locking operations of the sections is always recommended as it reduces the pneumatic pressure load during the operations, protecting the internal sealing gaskets.
USE AND MAINTENENACE LIGHT TOWER Models of Lighting Towers Lighting tower integrated in the generating set The lighting tower is located and positioned horizontally on the upper part of the generating set. For the operation of the telescopic mast, the system foresees a simple procedure of manual lifting of the mast/floodlights assembly. By acting on the locking handle, it is possible to rotate the lighting tower from the horizontal to the vertical position for its normal working.
Installation and mounting Fix the lighting tower bracket on the generator by means of U bolts, after adjusting the two telescopic brackets to the dimensions of the gen-set; then place the lifting plates between the two components. Assembly the bearing collar on the mast body. The fixing position may vary and depends on the generating set in your hands, in order to grant a safe grip of the support feet to the ground.
USE AND MAINTENENACE LIGHT TOWER Installation and mounting Combine the mast complete with collar to the fixed support by positioning it in the relevant bearing loops, and fastening it by the nuts at the ends. Fix the locking tie rod with the pin and the handle DANGER Avoid to position the stabilizers on holes or hollow of the ground as the generator and the lighting tower can be instable, with consequent risk of overturning.
Setting the Lighting Tower Lighting Tower integrated in the generating set 1) By acting on the locking handle, it is possible to rotate the lighting tower from the horizontal to the vertical position. Lower the stabilizing brackets by positioning them onto the floor. 2) Place on the mast head and fasten by the relevant hand-wheel, the floodlight unit. ATTENTION: PLEASE CHECK IF THE LOCKING THROUGH THE PROPER HANDLE HAS BEEN CARRIED OUT CORRECTLY.
USE AND MAINTENENACE LIGHT TOWER Lighting Tower separated from the generating set The lighting tower complete with tripod is independent and is supplied separately from the generating set. The mast and its lamp unit can be positioned separately. The operating instructions of this system are the same; it is however requested special attention when placing the unit on the ground and when adjusting the stabilizing brackets.
Switching the floodlights on 1) Start the generator 2) Wait for some seconds from the starting and put the lighting tower plug into the gen-set socket. If using a generator with manual rope-pull starting N (image 41) use the protection gloves to avoid injuries to the hands whilst releasing the recoil rope. When in use, the floodlights reach high temperatures and may cause contact burns. Adjust the directing by using the proper working gloves or wait for the complete cooling.
USE AND MAINTENENACE LIGHT TOWER Bring the light tower to its restore position Follow the below mentioned procedures to bring the light tower back to its restore position: • Switch the floodlights off and disconnect the electrical power • Lower the mast by opening the discharge valve placed at the pump or at the mast base (make sure to unlock the sections by releasing the clamps) • Unblock and remove the lamp unit from the mast head • Lift the stabilizers and put the mast in its housing Parking and Transp
TROUBLESHOOTING When pumping, the mast does not extend or extends partially 1. Obstruction or throttling of the pneumatic hose from the pump or from an external source to the mast Proceed by cleaning, dismounting and with the possible substitution with an equivalent spare part. 2. Pump inefficiency Try the pump without the hose; make sure that the air release valve on the pump itself is open. If the pressure supplied is not enough, please do the maintenance by replacing the internal gaskets. 3.
USE AND MAINTENENACE LIGHT TOWER At the restore stage the mast does not retract completely 1. Handle locked Loosen completely the handle which prevent from retracting 2. When temperature is quite low, it is possible to find ice inside the mast Wait till a sufficient temperature increase and retract the mast completely 3. A gasket is blocked Try to give pressure to the inlet to open the gasket 4. Mast buckling Due to overload, to a damage generated by a hit or other, the mast cannot be completely retracted.
