6. Operation
Operating the YIHUITONG 45T Firewood Processor involves several steps, from starting the engine to cutting and splitting logs. Always ensure safety protocols are followed.
6.1 Pre-Operation Checklist
- Verify all safety guards are in place and secure.
- Check engine oil and hydraulic fluid levels. Replenish if necessary.
- Ensure the fuel tank is adequately filled.
- Inspect the chainsaw chain for sharpness and proper tension.
- Clear the work area of any obstructions or debris.
6.2 Starting the Engine
- Ensure the emergency stop button is disengaged (pulled out).
- Follow the engine manufacturer's instructions for starting the 20HP GX630 engine. This typically involves checking the choke, throttle, and ignition switch.
- Allow the engine to warm up for a few minutes before engaging hydraulic functions.
6.3 Control Panel Functions

Figure 6.1: The hydraulic control panel, showing levers for various functions such as wood chain movement, chainsaw operation, and splitting wedge control.
The control panel features levers for managing different operations:
- Wood Chain Forward/Return: Controls the movement of logs on the feeding table.
- Chainsaw Running/Up: Engages the chainsaw for cutting and retracts it.
- Wedge Up/Down: Controls the vertical position of the splitting wedge.
- Splitting Cylinder Return/Split Wood: Activates the hydraulic ram to split the log.
- Wood Belt Forward/Return: Controls the direction of the conveyor belt.

6.4 Processing Logs
- Load a log onto the feeding table using the wood chain control. Ensure the log is positioned securely.
- Use the chainsaw control to lower the chainsaw and cut the log to the desired length (max 19.6 inches diameter).
- Once cut, retract the chainsaw. The cut log section will move towards the splitting wedge.
- Engage the splitting cylinder to push the log against the 4-way or 6-way wedge, splitting it into pieces.
- The split firewood will then be transported away by the conveyor belt.
- Repeat the process for subsequent logs.

8. Troubleshooting
This section provides solutions to common issues you might encounter with your firewood processor.
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine fails to start | No fuel, stale fuel, spark plug issue, emergency stop engaged, choke setting incorrect. | Check fuel level, use fresh fuel, inspect/replace spark plug, disengage emergency stop, adjust choke. |
| Chainsaw not cutting efficiently | Dull chain, incorrect chain tension, insufficient chain lubrication. | Sharpen or replace chain, adjust chain tension, check chain oil reservoir and pump. |
| Splitting force is weak | Low hydraulic fluid, air in hydraulic system, worn hydraulic pump, log too large/hard. | Check/fill hydraulic fluid, bleed air from system, consult service for pump issues, ensure logs are within specified diameter. |
| Conveyor belt not moving | Conveyor speed control valve closed, hydraulic issue, belt jammed or broken. | Open conveyor speed control valve, check hydraulic fluid, clear any jams, inspect belt for damage. |
| Unusual noises or vibrations | Loose fasteners, worn bearings, engine issue, hydraulic system problem. | Inspect and tighten all fasteners, check bearings, consult engine manual, or seek professional service. |
