4.3 Test:
No-load test of main lift: Turn on the power switch and turn the changeover switch to the "Main Lift" position. At this time, all oil-filling
ball valves are closed.
1 ） Press the "Up" button and observe whether the two platforms of main lift rise stably and synchronously.
2） Press the "Lock" button, then observe whether the safety jaws get into place precisely.
No person or article shall be on, under or near the lift or within specified areas during the test. Shut down the lift in time if
any abnormality is found and retest it after troubleshooting.
Load test: main lift
1 ） Turn the switch to the "Main Lift" position.
2） Drive a vehicle not exceeding the maximum lifting capacity onto the platform and apply the parking brake tightly. The person in
the vehicle shall leave the vehicle and the platform.
3） Press the "Up" button to lift the platforms of the main lift and observe whether they rise stably and synchronously.
4） Inspect the lift frame and the hydraulic pump unit for abnormal sounds.
5） Observe whether the highest position limit of the platforms is precise and reliable.
6） Press the "Lock" button, then observe whether the safety jaws get into place precisely.
No person or article shall be on, under or near the lift, within specified areas or in the vehicle during load tests.
The weight of the tested vehicle shall not exceed the maximum lifting capacity of the lift. Inspect the oil circuit and air circuit for oil
or air leakage. Shut down the lift in time if any abnormality is found and retest it after troubleshooting. Only trained operators are
allowed to operate the lift. Before operating the lift, inspect the lift as follows.
Operation precautions:
1 ） Eliminate barriers around and under the machine before operation
2） When lifting, no person shall be on, under or near the lift, within the specified area, or in the vehicle on the platforms.
3） Do not lift the vehicle or other cargoes that exceed the lifting capacity of the lift
4） During lifting, the vehicle brake shall be applied tightly and anti-skid devices such as anti-skid wedges（provided by the
user） shall be used
5） Always observe if the lift platforms act synchronously during lifting and lowering. Shut down the lift in time if any
abnormality is found and restart the lift only after troubleshooting
6） For maintenance or detection and adjustment in four-wheel alignment, press the "Lock" button to lock the safety jaws
of the two platforms at the same level. After the locking operation, personnel can enter the lift and work under the
vehicle
7） When conducting the lowering operation, please observe whether the two safety jaws are separated from the safety
gear completely; if not, stop the lowering operation
8） The platforms shall be lowered to the lowest position on the ground, drive away the vehicle and cut off the power supply
according to the instructions for electric operation when the machine will not be in use for a long time or overnight
Main lift（sub lift）lifting:
1 ） When the "Up" button is pressed, the oil pump runs to send the hydraulic oil to the hydraulic cylinder via the solenoid valve of the
main lift or sub lift, and then the platforms are lifted.
Main lift（sub lift）lowering:
1 ） When the "Down" button is pressed, the oil pump runs, the main lift （sub lift） rises first （after the safety jaws are
released）, and after a 2~2.5s delay, the motor stops running, the air cylinder's safety device opens, then the oil return solenoid
valve opens; at this time, the lift starts lowering.
2） Lock: when the Lock button is pressed, the oil return solenoid valve starts to return oil, and the mechanical safety mechanism is
locked.
