2.0.1 Main Structural Principles:
Lifting mechanism: Each column is installed with a hydraulic cylinder. When
hydraulic oil is pressed from power pack into the lower chamber of main cylinder, the piston rod moves upwards to drive the upward movement of carriage via leaf chain.
Load supporting mechanism: When vehicle drives into the working area, adjust
the angle and telescopic length of arms to align the lifting pads to the load bearing support point of the vehicle as described in the vehicle's operator's manual, then adjust the lower screw's height of lifting pad to adjust for vehicles with different chassis heights.
Balance mechanism: In order to keep machine balanced during lifting and
lowering; the two carriages are interconnected and forced to move synchronously by two cables. If the right and left carriages and arms are not at the same level, adjust the end nut of cable and pull wire ropes tight to make arms leveled.
Manual safety locking system: There are safety locking plates installed on the
two carriages and a toothed bar plate is welded on the internal wall of the column. During the lifting of the carriage, the safety locking plate goes up against the toothed bar plate by the tension of spring. When the carriage stops, the safety locking plate opens and then engages in the toothed bar slot to lock the carriage in position and prevents it from falling down. When the lowering operation is required, raise the carriage upward a little to loosen the safety locking plate from the toothed bar slot. Next, manually pull the steel wire rope to lift up the safety locking plate from the sliding plate. This will disengage the safety lock to allow lowering of the carriage. The lift incorporates a safety locking system that provides a dual safety protection since the manual pull mechanisms are installed on the both carriages. Therefore, to engage the safety locking system, the steel rope on the two carriages must be pulled respectively. To prevent the vehicle from slipping, the swing arm is installed with positioning mechanism. This mechanism automatically locks the swing arm during operation.
Safety lock scope: Safety lock mechanism is effective when the front end of carriage is
between 450 mm and 1900mm high above the ground.

3.0 Operation Description
3.0.1 Precautions for vehicle repair work
Different vehicles have different center of gravity positions. It is important to understand the position of center of gravity of the vehicle being serviced. When vehicle enters into the lift, make sure to align its center of gravity close to the vertical plane formed by the two columns. Adjust the swing arm, and align the lifting pad support to the lifting point of the vehicle.
For vehicle lifts with cross beam, pay attention to the roof of the car to prevent accidental impact with the cross beam during lifting operation.
Carefully read all warming labels. The hydraulic valves have been factory calibrated, and the user can't make self-
adjustment, otherwise the user will be responsible all consequences. Some specifications in the instruction manual are subjected to change without
notice depending on production needs.
3.0.2 Preparation before operation Lubricate contact surface of the carriage with general-purpose lithium grease (GB7324-87). All sliding surface should be coated evenly from the top to bottom. Fill hydraulic oil N32 or N46 to the oil reservoir of the power unit.
3.0.3 Inspection before operation Check to see if the motor power is installed properly. Check to see if all the connection bolts are fastened.
Note: Don't operate the lift with damaged cables or damaged and missing parts. The lift should only be operated after it is repaired and inspected by a qualified professional repair technician.

4.0 Lifting and Lowering the Vehicle:
4.0.1 How do I know if my vehicle is too heavy for a lift?
Two-post lifts generally have weight capacities ranging from 7,000 to 20,000 pounds, accommodating various vehicles from light-duty cars to heavy-duty trucks. It's important to note that each lift arm also has its own weight limit. For instance, a lift with a 10,000-pound total capacity may have each arm rated for 2,500 pounds. Therefore, if a vehicle's weight distribution exceeds this per-arm limit, the lift may not be suitable.
Calculating Required Lift Capacity
To determine the appropriate lift capacity:
1) Calculate Rear Axle Weight: Multiply the vehicle's total weight by the distance from the center of gravity to the front axle, then divide by the wheelbase.
2) Calculate Front Axle Weight: Subtract the rear axle weight from the total vehicle weight.
3) Determine Arm Capacity: Divide each axle's weight by two to find the load per arm.
For example, if a vehicle weighs 9,000 pounds with a 3,000-pound front axle and a 6,000-pound rear axle, each arm would need to support 3,000 pounds. In this case, a 10,000-pound lift with 2,500-pound arms would be insufficient. Opting for a 12,000-pound lift would be safer.
Importance of Choosing a Lift with Adequate Capacity
Selecting a lift with a capacity that exceeds the vehicle's weight requirements is advisable. This accounts for variables like vehicle modifications, additional equipment, or unexpected weight distributions. Many manufacturers recommend not exceeding 75% of a lift's rated capacity to maintain safety margins.

Safe Operating Practices
Adhere to Weight Limits: Never exceed the lift's total or per-arm weight capacities.
Proper Vehicle Positioning: Ensure the vehicle is centered and balanced on the lift to distribute weight evenly.
Regular Maintenance: Follow the manufacturer's maintenance schedule and conduct routine inspections to identify potential issues.
By understanding and respecting the weight capacities and operational guidelines of two-post lifts, automotive shops can ensure safer working conditions and prolong the lifespan of their equipment.

5.0 Hydraulic and Electrical System of the Equipment: 5.0.1 Hydraulic System of the Lift
Figure. 7 29
Sales & Support: (888) 636-1918; Email: info@autokato.com
5.0.2 The working principle of the hydraulic system is as follows: As shown in above figure 7, when the start button is pressed, the motor (2) is started, driving the oil pump (1), sucking the hydraulic oil from the oil tank into the oil cylinder (9), forcing the piston rod to move. At this time, the safety valve (5) is closed. (The safety valve controls the pressure in the system for the rated load, but when the pressure in the system exceeds the limit, the safety valve will overflow automatically to protect the hydraulic system). Release the start button to stop the oil supply and the lifting will stop. For lowering; first start Motor (2) to raise vehicle a little, pull the steel ropes on two carriages to release the safety lock mechanism, then press the lowering handle, the valve (6) is actuated, the hydraulic oil flows back and the lift starts lowering.

Incorrect installation of the lift system can cause damage to the lift or personal injury.
The manufacturer will not take any responsibilities for any damage caused due to incorrect installation and usage of this equipment, directly or indirectly.
The correct installation location shall be flat horizontal floor to ensure a proper horizontal lift.
A lift system installed on a slightly sloped floor can be levelled by proper shimming. Any large slope will affect the height of the lifting pad when at the bottom or the maximum lift height.
If the floor is of questionable slope, consider a visual inspection, or pour a new horizontal concrete slab if possible.
In short, the level of the lift relies on the level of the floor where it is installed. Do not install the lift on a grade that has a giant slope.
Installation site:
Select installation site based on the following conditions:
Lift can only be installed on concrete slab, which must have a minimum thickness of 5.9" (150 MM) with a 3000 PSI rating or more and should be aged at least 7 days.
Don't install the lift on any asphalt surface or any surface other than concrete. The concrete slab should be reinforced using steel bar. The concrete slab must be level. Check for possible obstruction, e.g. low ceiling height, wireways, conduits,
overhead pipeline, walkways, exits, etc. The front and back of the lift should be reserved with sufficient space to
accommodate all the vehicles (Fig. 10). (evaluating from the center line, max cantilever should be about 4m)
