 Fault Description |  Reasons and Solutions |
| Rotary Joint Leaks Oil | The sealing ring has aged. Replace the sealing ring. It is recommended to replace it every six months. |
| Reset the Jammed Trigger | It was caused by improper operation. By holding down the reset lever, applying pressure, then releasing the pressure, the situation can be restored; It is recommended that customers operate in accordance with the instructions provided in the manual. |
The Ratchet and the Large Pawl are Prone to having Teeth Broken | Improper operation resulted in; Release the button on the control handle, observe the pressure to drop to around 8-10 Mpa, and then perform the next up-pressure action |
The Rotary Joint is Broken, or the Screws are Loose |
|
Quick Connector - There are Connection Issues, Insufficient Pressure, and No Oil Injection | Connection obstacles: Foreign objects on the threads or external force damage to the joints; It is recommended to use a cleaning agent to clean the connection area of the connector, and then cover it with a dust cover |
| Fault Description | Reasons and Solutions |
| During the operation, the tensioner got stuck and could not be removed. | Improper operation; 1. Foreign objects on the screw; use an extended ratchet wrench to apply more force and remove it; 2. Screw turned in the wrong direction; operate the ratchet wrench in the opposite direction; 3. When removing the nut, if it is turned all the way down without being turned back half a turn, use the ratchet to turn it back half a turn in the opposite direction; |
| Oil leakage from the tensioner | Seal ring has aged; replace the seal; it is recommended to replace it every six months; |
| Fault Description | Reasons and Solutions |
| Pressure-regulating valve, valve plug, valve seat, (globe valve) | Lack of long-term maintenance and blockages caused by foreign objects; it is recommended to clean the entire machine regularly and replace the hydraulic oil; pressure relief valves, valve spools, valve seats, and shut-off valves (new machines: maintenance at 100 hours and 200 hours; in poor sanitary conditions, increase the maintenance frequency) |
| Oil leakage from the pressure gauge | The warranty period is six months, during which defective gauges will be replaced free of charge. The gauge must be calibrated once every six months during use; if the gauge is found to be inaccurate, it will be scrapped. |
| Quick-connect coupling experiences connection issues or fails to pass oil during pressure testing | Connection Issues: Foreign objects in the threads or physical damage to the coupling; Recommendation: Clean the coupling connection with a cleaning agent before and after use, then replace the dust cap. |
