Confirm whether to add 15# or 32# hydraulic oil. After adding, confirm whether the hydraulic pump is discharging oil (if the cylinder moves, it is discharging oil). If there is no oil discharging, it is necessary to exhaust the air. The way to exhaust the air is as follows: first open the refueling port (the exhaust valve is integrated inside the oil tank, just open the refueling port), start the motor for 20 seconds, then stop the motor, wait until the motor stops rotating.
