CHAPTER 6 – SAFETY Read this chapter carefully and completely because it contains important information for the safety of the operator and the person in charge of maintenance. The lift has been designed and built for lifting vehicles and making them stand above level in a closed area. - Page 17 PERSONNEL CRUSHING RISKS During lowering of runways and vehicles, personnel must not be within the area covered by the lowering trajectory. The operator must be sure no one is in danger before operating the lift. Fig. 7a Fig. 7c Fig. 7b BUMPING RISK When the lift is stopped at relatively low height for working, the risk of bumping against projecting parts...
- Page 18 RISKS RESULTING FROM IMPROPER LIGHTING Make sure all areas next to the lift are well and uniformly lit, according to local regulations. 6.10 RISKS OF BREAKING COMPONENT DURING OPERATION Materials and procedures, suitable for the designed parameters of the lift, have been used by the manufacturer to build a safe and reliable product.

CHAPTER 7 – INSTALLATION Only skilled technicians, appointed by the manufacturer, or by authorized dealers, must be allowed to carry out installation. Serious damage to people and to the lift can be caused if installations are made by unskilled personnel. CHECKING FOR ROOM SUITABILITY The lift has been designed to be used in covered and sheltered places free of overhead obstructions. - Page 20 Figure 13 – PIT FOUNDATION PLAN 330mm 770mm 580mm 580mm Min.1600mm Drive up Min.400mm Pipe (inner dia.100) placed here Pipe (inner dia.100) Groove 100X100mm To control unit Specifications of the pit must be adhered to. Failure to do so could cause lift failure resulting in personal injury or death.
