Precautions

1. When installing this product, park the car on a level surface, securely apply the parking brake, and turn the steering wheel fully to the left before carrying out the work.

2. Before the installation, use a neutral detergent (or cleaning detergent) and waste cloth to remove any dirt adhering to the car’s surface where the aero splash guard will be attached, and then dry the surface thoroughly. Moreover, if sand or mud adheres to the back of the clip insertion holes, etc., then clean the contaminated sections.

3. Install the aero splash guards before applying body coating. When installing them on a car that has been coated, remove the coating from the area where double-sided tape is to be applied before installation.

4. During the installation work, pay careful attention not to damage the car with tools, etc.

5. This manual describes how to install the product on the left side. Installation on the right side is symmetrical to that on the left side. Check the shape o f the components to be installed before carrying out the work.

6. When the air temperature is 15 °C or lower, use a hair dryer to warm up this product and the car surface where double-sided tape is to be applied to approx. 30°C to 50°C. Avoid using an industrial dryer.

7. Double-sided tape does not adhere unless it is adequately pressed. The adhesive strength of double-sided tape significantly decreases when the tape is reapplied. Position the tape properly before applying it to avoid the need for reapplication.

8. The adhesive strength of the double-sided tape gradually increases after it is applied. Avoid washing the car within 24 hours after installation. If the car needs to be washed or waxed on the day of the installation, leave it for at least one hour and use tape, etc. to cover the areas where double-sided tape is applied. Also be careful not to apply excessive force to the aero splash guards.

9. When blowing air after installing the product, keep the discharge port at least 30 0 mm away. If it is too close, it may cause the product to peel.

10. When a car has undergone a body coating treatment including glass coating, this product cannot exhibit its original adhesive performance.
Please confirm whether or not a body coating treatment is app lied to the car.
Moreover, ensure to remove dirt, oils and fats, etc. adhering to the surface on which the product is to be attached, and also use sufficient pressure to attach it to the car.

<<How to remove a body coating film and confirm the removal>>

– Use a fine-grained compound agent (so as not to affect the ca r’s paint) to rub the coating film off the area on which the product is to be attached.

– After polishing the area, spray water on it. You can confirm that the coating film has been removed when there is no repelling of water on the area.

Check for any significant misalignment or interference between the side spoiler and the front aero splash guard.

Remove the front aero splash guard and the clip ⑥.

Caution

The removed clip (small with a cross head) will be reused.
