- Do not operate the machine under the influence of drugs, alcohol, or medication that could impair judgment.
- Inspect the log splitter before each use for any signs of damage or loose components.
Specific Log Splitter Safety
- Keep hands and feet clear of the splitting wedge and ram at all times.
- Only split logs that fit within the specified dimensions (maximum 18 inches long, 8 inches wide).
- Do not attempt to split logs containing nails, wire, or other foreign objects.
- Be aware of the Proposition 65 warning: This product may contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.
3. Components Overview
Familiarize yourself with the main components of your hydraulic log splitter:
- Splitting Wedge: The component that applies force to split the log.
- Hydraulic Ram: The piston that pushes the log against the wedge.
- Operating Handles: Two levers used to activate the hydraulic pump.
- Log Cradle: Supports the log during splitting and helps prevent split wood from falling.
- Ram Return Spring: Facilitates quick retraction of the ram after splitting.
- Rear Wheels: For portability and easy movement of the unit.

4. Setup
The Sun Joe LJ10M log splitter typically requires minimal assembly and is designed for immediate use. Follow these steps to prepare your unit:
- Unpacking: Carefully remove the log splitter from its packaging. Inspect for any shipping damage.
- Positioning: Place the log splitter on a flat, stable, and level surface. This is crucial for safe and effective operation.
- Handle Installation (if required): If the operating handles are not pre-installed, attach them securely according to the diagrams in the separate assembly guide (if provided).
5. Operating Instructions
The Sun Joe LJ10M utilizes a manual hydraulic system to split logs. Follow these steps for efficient and safe operation:
Preparing the Log
- Select logs that are no more than 18 inches (46 cm) in length and 8 inches (20.3 cm) in diameter.
- Ensure logs are free of branches, knots, or foreign objects that could impede splitting.
- Place the log firmly in the log cradle against the splitting wedge.

Splitting the Log
- Engage the Pump: Use the two operating handles to pump the hydraulic ram forward. The 2-speed pump allows for faster initial movement and then increased force for splitting.
- Apply Force: Continue pumping the handles. The hydraulic ram will push the log against the splitting wedge, applying up to 10 tons of force to split the wood.
- Observe Splitting: The log cradle helps keep the log stable as it splits.

Ram Return
Once the log is split, turn the knob (typically located near the hydraulic cylinder) to release the hydraulic pressure. The ram return spring will automatically retract the ram, preparing the splitter for the next log. This mechanism ensures quick resets for continuous splitting.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Sun Joe LJ10M log splitter.
- Cleaning: After each use, clean the log splitter to remove wood chips, dirt, and debris. A weather-resistant coating protects the steel frame from elements.
- Hydraulic Fluid: Periodically check the hydraulic fluid level. Refer to the specific instructions in the full product manual for checking and refilling hydraulic fluid. If you notice any leaks, tighten connections or consult a qualified service technician.
- Lubrication: Lubricate moving parts as recommended in the full product manual.
- Storage: Store the log splitter in a dry, protected area when not in use. Its compact design and rear wheels facilitate easy storage and portability.
7. Troubleshooting
This section addresses common issues you might encounter with your log splitter.
| Problem | Possible Cause | Solution |
|---|---|---|
| Log splitter not developing full force. | Low hydraulic fluid level; air in the hydraulic system; log too large or dense. | Check hydraulic fluid level and refill if necessary. Bleed air from the system (refer to full manual). Ensure logs are within specified dimensions. |
| Ram does not retract fully or quickly. | Ram return spring issue; pressure relief valve not fully open. | Ensure the pressure relief knob is fully opened. Inspect the ram return spring for damage. |
| Hydraulic fluid leak. | Loose fittings; damaged seals. | Tighten all hydraulic fittings. If leaks persist, contact customer support. |
| Difficulty moving the unit. | Operating on uneven or soft terrain. | Move the unit on hard, level surfaces. Consider using a cart for transport over rough terrain. |
