ZSF Model Overview Diagram
The ZSF model is composed of lifting work platform, scissor lifting arm, lifting cylinder, hydraulic control system, base frame, walking system, hydraulic system, total of seven parts.

Working Principle
The oil pump is driven by the motor, and the high-pressure oil enters the P cavity of the valve block, and is output to the A cavity through the check valve 1, entering the lifting cylinder, so that the working platform slowly rises. Depending on the load, the working pressure is adjusted by the relief valve 2 to prevent overload or overpressure. When the working platform is lowered, the solenoid valve 4 is opened by power, and the lifting cylinder is under the gravity of the load of the working platform, and its hydraulic oil flows to the A cavity into the valve block, because the check valve 1 is closed in reverse, the hydraulic oil can only pass through the open solenoid valve 4, through the adjustable flow valve 3, and discharge into the oil tank from the O cavity, at this time the working platform slowly descends. Due to the pressure balance structure is adopted inside the valve, its closed start is only controlled by the solenoid, so it will not affect the stability of the lifting speed due to load fluctuations.

General Construction
ZSF model is composed of lifting work platform, scissor lifting arm, lifting cylinder, hydraulic control system, base frame, walking system, hydraulic system, total of seven parts. (See Figure 1 for details)

Working Principle

1. The oil pump is driven by the motor, and the high-pressure oil enters the P cavity of the valve block, and is output to the A cavity through the check valve 1, entering the lifting cylinder, so that the working platform slowly rises.
2. Depending on the load, the working pressure is adjusted by the relief valve 2 to prevent overload or overpressure.
3. When the working platform is lowered, the solenoid valve 4 is opened by power, and the lifting cylinder is under the gravity of the load of the working platform, and its hydraulic oil flows to the A cavity into the valve block, because the check valve 1 is closed in reverse, the hydraulic oil can only pass through the open solenoid valve 4, through the adjustable flow valve 3, and discharge into the oil tank from the O cavity, at this time the working platform slowly descends.
4. Due to the pressure balance structure is adopted inside the valve, its closed start is only controlled by the solenoid, so it will not affect the stability of the lifting speed due to load fluctuations. (See figure II)

Operation Instruction

1. Description of bottom controller operation and platform joystick Toggle switch:
   When the key rotates clockwise, the display can see the power display, at this time, the bottom controller up and down buttons can work, so that the platform rise and down freely. When the key rotates counterclockwise, the display can see the power display, at this time, the bottom controller, the rise and fall button can not work, but the working platform lever can work.

2. The walking mode and the lifting mode can be switched between each other (just the touch of a finger). When switching to walking mode, the white rabbit pattern is to accelerate, the turtle pattern is to slow down, and the finger is lightly pressed the enable button. The speed of the ascending mode is constant, but at the same time you need to press the enable key.
   Warning :

3. It is strictly forbidden overload .

4. When the lifting platform rised, it is strictly forbidden for the operator to do any force actions in the horizontal direction with the help of other items at height.

Technical Parameters

Common Maintenance

1. The battery is 80AH, 2x12V, the charging voltage is 110V, and the charging time is about 6-8 hours.

2. The hydraulic oil (32# hydraulic oil) should be replaced after 12 months of product use, and then replaced irregularly depending on the number of uses and the degree of hydraulic oil pollution. When replacing the hydraulic oil, the inner wall of the tank is thoroughly cleaned, and foreign objects such as metal particles, cotton yarn, and fibers cannot enter the tank

3. The pollution of hydraulic oil must be strictly prevented, there must be no water, acid, alkali and other impurities in the oil, and anti-rust oil must not be coated in the oil tank

4. If the solenoid valve is blocked by a foreign object, the hydraulic system fails. M14×1.5 screw plug drilled with Ф10 through hole in the middle, unscrew out the copper valve sleeve, pull it out together with the valve core, immerse it in kerosene and gently rotate the valve core, clean out the stuck debris, and then gently pull out the valve core, check the foreign matter and damage in the valve sleeve, carefully load the valve core after treatment, so that the valve core can slide smoothly in the valve sleeve.
   Pay attention to maintain the original assembly accuracy, and then load it into the valve body together, and then install the solenoid valve.

5. If the platform is found to fall automatically, check whether the check valve seal is reliable, whether the emergency oil drain valve is loose, or check whether there are soft fibers in the oil that cause the check valve to fail.

6. Periodically check whether the upper limit switch fails.

7. Non-professionals should not disassemble the hydraulic system parts at will, if you are not sure, do not repair yourself, you can entrust our factory for repair.

8. Fill the hinge of the support arm with lubricating oil regularly.

Cautions and Safe Notes

1. Personnel on the work platform after ascending are strictly prohibited to do all actions with lateral thrust or pull；

2. After installation and commissioning, it is forbidden in principle to adjust the speed of the rise and fall of the platform；

3. Not allowed to overload.

4. During the lifting operation, personnel are strictly prohibited from entering the
   bottom of the platform；

5. During maintenance, the bottom of the platform must be protected by safety
   support before entering the platform for maintenance；

6. It is strictly forbidden to risk overloading operation by illegal means of increasing the pressure of the hydraulic system;

7. Parts and components may not be removed or modified without authorization.
