SAFETY INFORMATION

WARNING

• DO NOT operate in an enclosed area as you risk carbon monoxide poisoningfromthe engine exhaust.
• DO NOT search for leaks with your hands or other body parts. Pressurizedfluidcan penetrate the skin causing serious injury or death. If the fluid penetrates theskin, seek medical attention immediately.
• DO NOT remove the hydraulic reservoir cap while the power unit is running.
• Wear proper eye protection when searching for a high-pressure hydraulic leak.
• Ensure the pressure does not exceed the maximum pressure given inthespecifications.
• Operate in a well-lit, clean, and safe environment free of distractions.
• Wear appropriate protective equipment when operating or near the running power unit: goggles that provide front and side protection for eyes, protective glovesappropriate for the work material, steel-toed boots to prevent injury fromfallingobjects, and hearing protection gear for the noise level.
• Make sure all components are maintained in good condition. DO NOT operateif any parts of the power unit are damaged or malfunctioning. Replace any damagedor malfunctioning components.
• Always check the electrical connections are snug before use.
• DO NOT leave the equipment unattended while it is powered on.
• DO NOT operate when tired or under the influence of medication, drugs, or alcohol.
• DO NOT let children or untrained adults operate the power unit.
• Keep bystanders at a safe distance when the power unit is in operation.
• DO NOT modify the equipment in any way. Unauthorized modification may bedangerous, impair function, and reduce the service life of the equipment.
• Keep  theinterior of the reservoir, hydraulic cylinder, and oil pipelines clean to avoiddamage to the control valve.

1. Make sure the electrical supply is compatible and the motor housing is well grounded.
2. The motor’s junction box should be watertight and moisture-proof.
3. Ensure your hydraulic hoses have an inner diameter no less than 0.55 in. (14 mm).
4. The positive pole of the power supply should be connected to the positive poleof the relay while the negative pole of the power supply should be connected tothenegative pole of the electronic motor. The power supply wire must be copper wire3.1–3.8 sq. in. (20–25 cm2) incross section.
5. Make sure all the fittings and connections are properly connected and tightenedbefore operating the equipment.
6. Select a standard or premium quality, mineral-based hydraulic oil suitable for thetemperature range the power unit will be operating in.
7. Oil should be passed through a filter with gaps no larger than 25 µmbefore use.
8. The optimum system operating temperature for the hydraulic oil is 120°F (49°C) andshould not exceed 180°F (82°C).
9. Fill the reservoirto between ½ and 1 in. (5–30 mm) below its top. Use hydraulic oil with5–15W (ISO VG 22–46) viscosity. High viscosity oil is better for high temperatureenvironments and lower viscosity oil for low temperatures.
10. Ensure the power supply is connected correctly and then install the oil pipelines.
11. Press the UP button to turn on the motor. The motor should power the oil pumptogenerate pressure and cause oil to be discharged. Release the UP button andthemotor should cease operation. Looking from the rear of the motor, the motor shouldturn counterclockwise. If it does not, cease operation and contact customer service.
12. At the end for the hydraulic cylinder’s travel, press the DOWN button to allowtheoil to return and the hydraulic cylinder to return to its original place. As this isasingle acting pump, the motor will do no work during this action.
13. The first time operating the power unit, let it run under zero load for 5 minutestocycle the actuators in order to remove any entrained air

MAINTENANCE

1. Inspect the equipment components periodically. Replace any damaged, worn, or malfunctioning components.
2. The reservoir, actuators, and pipeline should be kept clean to prevent the introduction of foreign material into the system.
3. The reservoir should be adequately filled with oil during use. Refill as necessarytoavoid the pump sucking in air.
4. The hydraulic oil should be replaced after working for 100 hours when first installed. Subsequently, it should be replaced every 1500 working hours or one year, whichever comes first.

TROUBLESHOOTING

If no oil rises or the oil provides

• If pressing the UP button does not start the motor:
  • Check if the battery is low.
  • If the battery is good, then check if the connections are correct and snugwithout unwanted grounding.
  • You may connect the motor directly to both ends of the power supply to checkif there is something wrong with the motor. In this case, the positive end of thepower supply should be connected with the positive end of the motor whilethenegative end of the power supply should be connected to the negative endof the motor.
  • If there is still no reaction, change the battery. There might also be a damagedrelay or a badly connected control box. If all of three are fine, replace the motor.
• If the motor works properly, but no oil is discharged or the oil provides insufficient pressure:
  • Check if the indicator light of the electromagnetic coil is lit or not.
  • If the light is lit, check if the circuit is properly connected. Whenthehydraulic cylinder is going upward, the indicator light of theelectromagnetic oil must be lit and there should be electricity in the coil.
  • If the light is off while the motor runs normally, but there is no oil dischargeor insufficient pressure, take off the electromagnetic coil and clean its corewith diesel or regular gasoline. Once cleaned put it back on to do thetest again. You may need to change the electromagnetic solenoid valve.
• If you have tried all the above, but the problem still persists, there might beachoked pipeline or a problematic hydraulic cylinder. Inspect and fix or replaceif necessary.
• Alternatively, the amount of pressure for your job maybe exceed 3200 psi, in whichcase a larger hydraulic pump is required.
