3. Installation Instructions

Proper installation is crucial for the safe and effective operation of your lift supports. Follow these steps carefully:

• Note: Ensure the gas strut rod is installed downwards to maintain proper lubrication of the main seal. This also contributes to better cushioning.
• Caution: The gas strut is delivered in an extended state. DO NOT attempt to compress it by hand before installation.

1. Step 1: Mark the Upper Mounting Point. When positioning the gas spring, start by identifying the upper mounting point. This point should be approximately 1/3 of the total length of the lid from its hinge.
2. Step 2: Mark the Lower Mounting Point. Open the lid to the desired angle. Mark the lower mounting point. It is not necessary for the strut to be perfectly vertical; the installation angle is important for optimal function.
3. Step 3: Secure Mounting Brackets. Attach the provided mounting brackets to the marked upper and lower points using appropriate fasteners (not included, unless specified). Ensure they are securely fastened.
4. Step 4: Attach Gas Spring. Press the ends of the new gas spring onto the ball studs of the installed mounting brackets. Ensure a firm connection.
5. Step 5: Adjustment (if needed). If the lid does not stay open or is too difficult to close, minor adjustments may be required. If the lid cannot be held up, move the upper mounting point 0.79 inches (2 cm) further from the hinge. Repeat this adjustment if necessary. If the lid cannot be closed, move the upper mounting point 0.79 inches (2 cm) closer to the hinge. Note that the lower mounting point may also need adjustment in conjunction with the upper point.

4. Operation

Once installed, the lift supports will assist in opening and holding open the lid, hood, or cover they are attached to. They provide a controlled lift and a stable open position, reducing the effort required to access the compartment. To close, gently push the lid down; the gas springs will provide resistance for a smooth closing action.

5. Maintenance

These lift supports are designed for minimal maintenance. To ensure their longevity and proper function:

• Periodically inspect the mounting points and connections for any signs of wear, looseness, or damage.
• Keep the rod and cylinder body clean from dirt, dust, and debris. Wipe with a clean, damp cloth if necessary.
• Avoid applying excessive force or bending the rod, as this can damage the internal seals and affect performance.
• Do not lubricate the rod with oil or grease, as this can attract dirt and damage the seals.

6. Troubleshooting

If you encounter issues with your lift supports, consider the following common problems and solutions:

• Lid does not stay open: The lift supports may be too weak for the weight of the lid, or the mounting points may be incorrectly positioned. Refer to Step 5 of the Installation Instructions for adjustment guidance. Ensure the correct force rating (100lb/445N) was selected for your application.
• Lid is difficult to close: The lift supports may be too strong for the weight of the lid, or the mounting points may be too far from the hinge. Refer to Step 5 of the Installation Instructions for adjustment guidance.
• Squeaking or grinding noise: Check mounting points for proper alignment and tightness. Ensure no foreign objects are interfering with the strut's movement.
• Strut appears damaged or leaking: If the strut shows signs of physical damage, bending, or fluid leakage, it should be replaced immediately. Do not attempt to repair damaged gas springs.
