On the panswork forum, a user shared multiple issues they encountered with their Bobcat S70. The main problems included difficulty starting the machine, hydraulic system failure, and unstable operation, making it difficult to use the equipment properly. These issues require systematic troubleshooting to pinpoint the root cause.
Starting Issues
The user reported difficulty starting the Bobcat S70, even though the battery had sufficient charge. Initial diagnostics suggested that the issue might be with the electrical connections or the starter motor itself. It is crucial to check the electrical connections, ensure contact points are clean, and inspect the starter motor’s condition. If the electrical system is functioning well, users should also check the starter relay and fuse for any damage.
Hydraulic System Failure
Hydraulic system issues were another common problem. The user mentioned slow response in the hydraulic system, especially when raising the lift arms. Upon further diagnosis, it was found that there might be a hydraulic fluid leak or insufficient fluid levels. The focus of troubleshooting should be on the hydraulic filter, hoses, and connections to ensure the oil pathway is clear and seals are intact. Regularly checking hydraulic fluid quality and levels is an essential preventive measure.
Unstable Operation
In addition to starting and hydraulic system problems, the user reported unstable operation, particularly under heavy load. After investigation, it was concluded that the issue might be linked to the hydraulic pump, valves, or unstable system pressure. Checking the hydraulic pump’s condition and ensuring that valves and pressure regulation systems are functioning correctly is critical for resolving the unstable operation.
Solutions and Recommendations
Common issues with the Bobcat S70, such as starting difficulties, hydraulic system failures, and unstable operation, can usually be resolved with thorough troubleshooting and timely repairs. Regular inspections and maintenance are essential to keep the equipment functioning smoothly and prevent recurring issues.

Solutions and Recommendations
- Check the Electrical System and Starter Motor: Inspect the electrical connections for stability, clean the contact points, and verify that the starter motor and starter relay are working properly.
- Inspect the Hydraulic System: Check the hydraulic fluid level and quality, look for leaks, and ensure hydraulic hoses and seals are intact.
- Inspect the Hydraulic Pump and Valves: Check the hydraulic pump and adjustment valves to ensure stable pressure in the system.
- Regular Maintenance: Regularly inspect the hydraulic system, starting system, and electrical components, and perform preventive maintenance to avoid future issues.
