LOWERING HANDLE (3) • When the air control valve is not pressed, press the lowering handle to lower the lift to engage the nearest latch rack. • When the latches are released by pressing the air control valve, press the lowering handle in the meantime to lower the lift to the desired height under its weight and the load lifted until the handle is released. Lift operation can be summarized into three steps: 8.1.1 Lifting • Pay attention to overhead clearance; • The lift must be fully lowered and no one in the service area while the vehicle is driven onto the lift; • Position the wheels in center of each runway; • Stop the vehicle when it contacts the front stops or at the desired position; • Set the parking brake or place the wheel chops on each side of the rear wheels; • Make sure the all personnel must be exit before the lift is raised; • Raise the lift by pushing the lifting button until reaching the desire height. Operation And Use PVL14OF-EXT 41 8.1.2 Standing • Press the lowering handle to engage the nearest latch position; • Always ensure that the latch in each column is engaged before any attempt is made to work on or near the vehicle. 8.1.3 Lowering • Be sure the safety area is free of people and objects; • Raise the lift high enough by pushing the lifting button to clear off the locks; • Lower the lift by pressing both the air control valve and the lowering handle; • Observe the lift and the vehicle to be sure the lift is level while being lowered; • Lower the lift fully; • Remove the wheel chops and check to be sure that the area is clear before removing the vehicle off the lift. Operation And Use PVL14OF-EXT 42 Maintenance Only trained personnel who knows how the lift works, must be allowed to service the lift. To service properly the lift, the following has to be carried out: • use only genuine spare parts as well as equipment suitable for the work required; • follow the scheduled maintenance and check periods shown in the manual; • discover the reason for possible failures such as too much noise, overheating, oil blow-by, etc. • refer to documents supplied by the manufacture or dealer to carry out maintenance. Before carrying out any maintenance or repair on the lift, disconnect the power supply, padlock the general switch and keep the key in a safe place to prevent unauthorized persons from switching on or operating the lift. 9.1 Ordinary maintenance The lift has to be properly cleaned at least once a month using self-cleaning clothes. The use of water or inflammable liquid is strictly forbidden. Be sure the rod of the hydraulic cylinders is always clean and not damaged since this may result in leakage from seals and, as a consequence, in possible malfunctions. Maintenance PVL14OF-EXT 43 9.2 Periodic Maintenance • Check hydraulic connections and hoses for leaks Daily preoperation • Check air connections and hoses for leaks • Check safety lock audibly and visually while in operation • Check bolts, nuts and screws are tight • Check all cable connections, pins and bolts to insure proper mounting • Check all anchor bolts and retighten if necessary • Check columns for square-ness and plumb Every 1 month • Check steel cable tension, adjust if necessary • Check all lifting pads, replace if necessary • Lubricate sliders with grease • Lubricate all pivot pins • Check the hydraulic oil, fill or replace if necessary • Check hydraulic systems for proper operation • Verify that all components and mechanisms are not damaged Every 12 months • Verify the equalizer cables are not worn, change if necessary • Check the electrical system to verify that the motors operate properly (this work must be carried out by skilled electricians) • Empty the oil tank and change the hydraulic oil Maintenance PVL14OF-EXT 44 Troubleshooting A list of possible troubles and solutions is given below Trouble: The lift does not work Possible Cause: Solution: There is no power Check Power on to restore if necessary The electrical wires are disconnected Reconnect The circuit breaker are blown Check for correct voltage The lift is overloaded The motor direction of rotation is not correct.
