6. Operation
This log splitter can operate in both horizontal and vertical positions, offering flexibility for various log sizes and user preferences.
6.1 Starting the Engine:
- Ensure the log splitter is on a level surface and the wheels are chocked if not hitched.
- Turn the fuel valve to the "ON" position.
- Move the choke lever to the "CHOKE" position (if the engine is cold).
- Set the throttle to the "FAST" position.
- Pull the starter rope firmly until the engine starts.
- Once the engine starts, gradually move the choke lever to the "RUN" position.
6.2 Switching Between Horizontal and Vertical Positions:
The log splitter can be easily converted between horizontal and vertical splitting modes. Consult the full manual for specific instructions on safely changing the beam position.

8. Troubleshooting
This section provides solutions to common operational issues. For problems not listed here, contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine does not start | No fuel, old fuel, spark plug issue, choke setting. | Check fuel level, use fresh fuel, inspect/replace spark plug, adjust choke. |
| Loss of splitting force | Low hydraulic fluid, air in hydraulic system, worn pump. | Check hydraulic fluid level, bleed air from system (refer to manual), inspect pump. |
| Ram moves slowly | Low hydraulic fluid, incorrect engine RPM, cold hydraulic fluid. | Check fluid level, ensure engine is at full throttle, allow fluid to warm up. |
| Log jams on wedge | Log too large, knot in log, improper log placement. | Do not force. Reverse ram, reposition log, or split smaller pieces. |
