| Warning | Detail |
|---|---|
| Hydraulic pressure | Hydraulic systems can store high pressure. Always relieve pressure before servicing. |
| Hot surfaces | Allow machine to cool before touching hydraulic components. |
| Electrical shock | Always disconnect battery before working on electrical components. |
| Eye protection | Wear safety glasses when working with hydraulic systems. |
| Lifting | Use proper lifting techniques; some valves may be heavier than expected. |
| Voltage match | Confirm 12V or 24V before connecting. Wrong voltage will destroy coil. |
