Key Features
27-Ton Splitting Force
Powerful splitting capability handles hardwoods up to 24" in length and 24" in diameter with ease, including tough knotty logs.
Horizontal/Vertical Operation
Convertible design allows for both horizontal splitting for most logs and vertical operation for large, heavy rounds.
4-Way Wedge
Convertible wedge allows for single or 4-way splitting, increasing productivity by creating four pieces in one cycle.
Auto-Return Valve
Automatic return valve speeds up cycle time by automatically returning the ram when pressure is released.
Two-Stage Hydraulic Pump
High-speed/low-pressure pump for fast ram extension, switching automatically to high-pressure for splitting tough logs.
Log Cradle
Integrated log cradle holds logs in position during splitting, improving safety and reducing manual handling.
Operation Modes Explained
Horizontal Mode
Standard operation for most splitting tasks, provides stability and easy log loading
Vertical Mode
For large, heavy rounds that are difficult to lift onto the beam
4-Way Splitting
Maximum productivity for medium-sized logs, creates four pieces per cycle
Single-Wedge Mode
For large diameter logs or particularly tough, knotty wood
Manual Control
Full operator control for precise splitting of unusual shapes
Auto-Return
Automatic ram return for faster cycle times during production splitting
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine won't start | Fuel valve off, choke incorrect, spark plug issue | Check fuel supply, proper choke position, inspect spark plug |
| Low splitting power | Hydraulic fluid low, pump issues, relief valve setting | Check fluid level, inspect pump, adjust relief valve |
| Slow cycle time | Hydraulic fluid cold, pump wear, valve issues | Allow warm-up time, check pump performance, inspect valves |
| Hydraulic leaks | Loose fittings, damaged hoses, seal failure | Tighten fittings, replace damaged hoses, replace seals |
| Ram won't extend | Control valve issue, hydraulic lock, linkage problem | Check control valve, release pressure, inspect linkage |
| Excessive vibration | Unbalanced load, loose components, engine issues | Center log properly, tighten all hardware, check engine mounts |
