4.3. Types of vehicles suitable for This lift is suitable for virtually all vehicles with total weight and with dimensions not exceeding the below data. MMUB30Y Maximum weight not exceed than 3000kg. The max dimension of vehicle: The following diagrams illustrate criteria used to define the operating limits of the lift.

Picture 5 MMUB30Y Max. 2000 4000 1900 The lower parts of the vehicle under-body could interfere with structural parts of the lift. Take particular parts of the sports-car. The lift will also handle customized or non-standard vehicles provided they are within the maximum specified carrying capacity.
Page 10 Risk of electric shock: a specific safety notice placed on the lift in areas where the risk of electric shock is particularly high. Risk and protection devices For optimal personal safety and safety of vehicles, observe the following regulations: -Do not enter the safety and safety of vehicles is being lifted. (Picture 7) -Be sure to lift only approved vehicles, never exceed the specified carrying capacity, maximum height, and projection (vehicle length and width);...
Page 11 Picture 11 Risk of impact Before the operator begins up and down movements, make sure that there are no personnel inside the danger zone. When, due to operational reasons, the lift is stopped at relatively low elevations (lower than 1.75m above the ground) personnel must be careful to avoid impact with parts of the machine not marked with special colors.
Page 12: Installation
Risk of electric shock in areas of insulated and shattered electric equipments Do not use jets of water, steam solvents or paint next to the lift, and take special care to keep such substances clear of the electrical control panel. Risks related to appropriate lighting The operator and the maintenance fitter must be able to assure that all the areas of the lift are properly and uniformly illuminate compliance with the laws in force in the place of installation.
Page 13 Picture 15 Note: The foundation of the end of the lift platformP1, P2 is the structure of concrete. When the thickness of inside level ground is less than 150mm, the end of P1, P2 should be irrigated the acreage: 6000×2500mm and thickness of concrete≥150mm The basic thickness of concrete and leveling are keys, shouldn’t egregiously expect the ability of level adjustment of machine-self.

Page 15: Platform Installation
Platform Installation: -Place two lift platforms on the position of the location -The bottom of oil cylinder is located in the frontage of machine (the direction of getting on the vehicle) -Use fork car or other lifting equipments to lift the platform (Picture17) and make sure that the safety equipment of machine is both turned on and locked.
Page 16 Level adjustment -By using a level bar and the horizontal pipe and adjusting the adjustment screws at two sides of the base plate. -If platform unevenness is resulted from basic unevenness, use iron block to fill up the low place.(Picture -After level adjustment, insert the central expanded nail of ground bolts and use heavy hammer to hammer it.(Picture 19) -Screw down the ground bolts cap(Picture 20)
Page 17 Only skilled special person is allowed to perform the operations. - open the control box’ front cover -connection of power supply: the 400VAC three-phase and four-line connection wires (4×2.5mm2 cable wire) for power supply are connected to L1,L2,L3, and PE labeled entering-wire terminal in control box. The PE ground wire is connected under the bolt marked ground firstly (Picture 22) and then connected under the bolt marked ground of two platforms.

In the process of windpipe installation, the windpipe cannot be folded or tied to avoid that the gas loop is not smooth or it is jammed. Before leading the compressed air supply pipe to the air supply jaws of pneumatic electromagnetic valve inside the control box, should extra install grease separator to separate compressed air, avoiding the failure of pneumatic cell action.
Page 19 at the same level. Then close the valve I OR the valve H .Open the valve G. Check: whether the locations of two safety-pawl equipments are agile and reliable, no leakage of the hydraulic system and the air system. When conducting oil make-up operation, the platforms must not be load. Picture 26 No load of main machine test: -Turn on the power QS.
Page 20: Operation
8. Operation Only skilled and having been trained personnel is allowed to perform the operations. Check proceedings as following. Text before operation: -Clear obstacles around the lift before operation. -Pay attention to the synchronization and placidity of the lifting. -Check whether the safety claw is flexible and reliable. -Check whether the lift will stop automatically when it lift to the highest position -No air leakage in the solenoid valve,air cylinder,air hose and union.
