Setup and Installation
Proper installation is crucial for the safe and effective operation of the gas spring. Ensure you have the correct tools and understand the mounting requirements for your specific application.
Installation Steps:
- Identify Mounting Points: Determine the optimal mounting locations on your application (e.g., hatch, lid, door) to achieve the desired opening angle and support.
- Secure Brackets: If not already present, install appropriate mounting brackets at the identified points. Ensure they are securely fastened and capable of withstanding the gas spring's force.
- Attach Gas Spring: Connect the ends of the gas spring to the mounting brackets. The gas spring typically features ball-and-socket or eyelet fittings for easy attachment. Ensure the connections are firm and allow for smooth articulation.
- Test Operation: Carefully test the movement of the application (e.g., open and close the hatch) to ensure the gas spring operates smoothly and provides adequate support without binding or excessive strain on the mounting points.

Important: Always ensure the gas spring is installed with the rod end facing downwards when the application is closed. This helps lubricate the seal and prolong the life of the unit.
Operating Instructions
The Attwood gas spring is designed to assist in lifting and holding open various components. Its operation is passive, meaning it provides force when extended and resists compression.
Usage:
- Lifting Assistance: When opening a heavy lid or hatch, the gas spring will provide an upward force, making the lifting process easier and smoother.
- Holding Open: Once the lid or hatch is fully open, the gas spring will hold it in the open position, preventing it from closing unexpectedly.
- Controlled Closing: When closing, the gas spring will provide resistance, allowing for a more controlled and slower descent, preventing slamming.
Do not attempt to manually compress the gas spring beyond its designed travel or apply excessive force that could damage the unit or its mounting points.
Maintenance
Attwood gas springs are largely maintenance-free. However, periodic inspection can help ensure longevity and optimal performance.
Maintenance Tips:
- Regular Inspection: Periodically check the gas spring and its mounting points for any signs of wear, corrosion, damage, or loose connections.
- Cleanliness: Keep the rod surface clean and free from dirt, dust, or debris. Avoid using abrasive cleaners or solvents that could damage the seal. A damp cloth is usually sufficient.
- Lubrication: The gas spring is self-lubricating internally. Do not apply external lubricants to the rod, as this can attract dirt and compromise the seal.
- Storage: If storing the gas spring separately, keep it in a clean, dry environment, ideally with the rod end facing downwards.
Replace the gas spring if you notice any significant loss of force, leakage, or physical damage to the unit or its connections.
Troubleshooting
If you encounter issues with your Attwood gas spring, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Gas spring does not hold open or provides insufficient force. | Loss of gas pressure due to seal failure or internal damage. Incorrect force rating for application. | Replace the gas spring. Verify the required force for your application and ensure the replacement matches. |
| Gas spring is too stiff or difficult to compress. | Incorrect force rating (too high). Binding due to misalignment or damaged mounting points. | Ensure the gas spring force matches the application's requirements. Check mounting points for alignment and freedom of movement. |
| Squeaking or grinding noise during operation. | Dirt or debris on the rod. Misalignment of mounting points. | Clean the rod surface. Check and correct mounting alignment. |
| Visible oil leakage from the seal. | Damaged seal. | Replace the gas spring immediately. |
If troubleshooting steps do not resolve the issue, contact Attwood customer support or a qualified technician.
