1. If the amount of oil in the pump body is insufficient, you need to add working oil (10# engine oil) to the pump before it can work.
2. Estimate the weight of the lifted items and avoid overloading. The hydraulic wrench transmits power to the working head through the high-pressure oil pipe and the hydraulic pump, which drives the working head to tighten or loosen the nut. The hydraulic pump can be driven by electricity or compressed air. The working head of the hydraulic wrench is mainly composed of three parts, the frame (also called the shell), the oil cylinder and the transmission part. The output force of the oil cylinder, the piston rod of the oil cylinder and the transmission part form a motion pair. The distance from the center of the oil cylinder to the center of the transmission component is the hydraulic wrench amplification arm. The oil cylinder output multiplied by the arm is the theoretical output torque of the hydraulic wrench. The actual output torque is smaller than the theoretical output torque.
3. Determine the center of gravity of the lifting object, choose (xuanze) jack (Jack0 focus point), and consider whether the ground is soft or hard to be padded with tough wood, so as to avoid the danger of dumping during lifting .
4. Jack (After Jack0 lifts the heavy object, you should use tough wood to sustain the heavy object in time. It is forbidden to use the jack as a support to avoid unbalanced load (Balance) and the risk of dumping.
5. When using, first connect the quick connector of the hand pump with the top, then select the position (position), and tighten the oil drain screw on the oil pump (Deep well pump) to work. Loosen the oil drain screw and unload the oil cylinder.
6. For electric pump, please refer to the manual of electric pump.
Through the introduction of (tōng guò) above, we should know that the electric hydraulic jack (the speed of Jack0 stroke is not controlled by the flow rate (unit: cubic meter per second)).
