2. Safety Instructions
Always prioritize safety when operating power tools. Read and understand all instructions before use. Failure to follow these instructions may result in electric shock, fire, and/or serious injury.
- Wear Personal Protective Equipment: Always wear safety glasses, hearing protection, gloves, and a helmet with a face shield. Sturdy footwear and long trousers are also recommended.
- Inspect the Tool: Before each use, check the pole pruner for any damage, loose parts, or worn components. Ensure the chain is sharp and correctly tensioned.
- Check Oil Level: Verify that the chain oil reservoir is adequately filled to ensure proper lubrication during operation.
- Power Cord Safety: Keep the power cord away from the cutting area. Avoid operating the tool in wet conditions or near water. Use a residual current device (RCD) for added protection.
- Maintain a Secure Stance: Always maintain proper footing and balance. Do not overreach.
- Clear Work Area: Ensure the work area is free of bystanders, children, and pets. Remove any obstacles that could interfere with operation.
- Avoid Contact with Electrical Lines: Never operate the pole pruner near overhead power lines.
- Proper Handling: Hold the tool firmly with both hands. Do not operate the tool with one hand.
3. Setup
3.1. Chain and Guide Bar Assembly
The chain and guide bar are designed for easy, tool-free installation and tensioning. Refer to the diagram for proper placement.
Figure 3.1: The pole pruner features a tool-free mechanism for easy chain tensioning and assembly, indicated by the crossed-out wrench icon.
3.2. Filling the Chain Oil Reservoir
The pole pruner features an automatic chain lubrication system. Ensure the oil reservoir is filled with appropriate chain lubricant before each use.
- Locate the oil reservoir cap on the motor unit.
- Unscrew the cap and carefully fill the reservoir with high-quality chain lubricant.
- Monitor the oil level through the sight glass to prevent running dry.
- Securely replace the cap.

4. Operating Instructions
4.1. Extending the Telescopic Pole
The aluminum telescopic handle allows for adjustable reach to access high branches.
- Loosen the locking mechanism on the telescopic pole.
- Extend the pole to the desired length, up to 2.57 meters.
- Securely tighten the locking mechanism to prevent the pole from retracting during use.

4.2. Adjusting the Motor Head Angle
The motor unit can be tilted by 30 degrees for optimal cutting of very high branches.
- Locate the angle adjustment mechanism on the motor head.
- Adjust the head to the desired 30-degree angle for improved access and cutting efficiency.
- Ensure the mechanism is locked in place before operation.

5. Maintenance
5.1. Chain Tensioning
Regularly check and adjust chain tension. The GC-EC 7520 T features a tool-free chain tensioning system for convenience.
- Ensure the tool is disconnected from the power supply.
- Turn the tensioning knob or lever until the chain is snug against the guide bar but can still be pulled freely by hand.
- Avoid over-tightening, as this can cause premature wear.
5.2. Chain Lubrication
The automatic lubrication system ensures the chain is continuously oiled during operation. Always check the oil level before and during extended use.
- Refer to Section 3.2 for instructions on filling the oil reservoir.
- The large sight glass allows for quick visual inspection of the oil level.
5.3. Cleaning and Storage
After each use, clean the pole pruner to remove sawdust, sap, and debris. Store the tool safely.
- Disconnect the tool from the power supply.
- Use a brush or cloth to clean the guide bar, chain, and motor housing.
- Apply the included guide bar protection for clean and safe storage.

6. Troubleshooting
This section addresses common issues you might encounter with your Einhell pole pruner.
| Problem | Possible Cause | Solution |
|---|---|---|
| Chain not cutting effectively or jamming | Dull chain, incorrect chain tension, insufficient oil, cutting soft/flexible branches. | Sharpen or replace chain. Adjust chain tension (see Section 5.1). Fill oil reservoir (see Section 3.2). Ensure the branch is rigid enough to support the pruner during cutting. |
| Chain derails from guide bar | Incorrect chain tension, worn guide bar, improper cutting angle, cutting flexible branches. | Adjust chain tension (see Section 5.1). Inspect guide bar for wear and replace if necessary. Ensure the pruner is placed firmly on the branch before cutting. |
| Motor stops or does not start | No power supply, thermal overload, damaged cable. | Check power connection and circuit breaker. Allow motor to cool down if overloaded. Inspect power cable for damage; replace if necessary. |
| Oil leakage | Overfilled reservoir, loose cap, seal damage. | Ensure reservoir is not overfilled. Tighten oil cap. If leakage persists, contact customer support. |
