Important Usage & Installation Notes

  1. Verify Compatibility Before Purchase

    • Match your truck model, mirror type, and mounting method (adhesive vs clip).

    • Some SINOTRUK variants use slightly different shapes.

  2. Clean Mounting Surface First

    • Use alcohol or degreaser to remove oil, wax, or dust from the base mirror.

    • Ensures strong adhesion if using sticky pad.

  3. Adjust to Optimal Viewing Angle

    • Tilt the mirror downward/outward to cover the blind zone between the cab and trailer.

    • Should show tires and curb line clearly.

  4. Secure Firmly

    • If using a clip or bolt, ensure it is tightened securely — vibrations can loosen it over time.

  5. Avoid Obstructing Main Mirror View

    • Position so that it supplements, not blocks, the primary mirror's field of vision.

  6. Use Genuine or High-Quality Units

    • Low-cost mirrors often have distorted lenses or weak mounts — avoid "bubble" effects.

  7. Replace If Damaged

    • Cracked glass, warped frame, or loose mounting reduces effectiveness — replace immediately.

  8. Do Not Touch Mirror Surface

    • Oils from fingers can degrade coatings — handle by edges only.

  9. Regular Cleaning Recommended

    • Wash with mild soap and water; dry with soft cloth.

    • Avoid abrasive cleaners or pressure washing.

  10. Storage Advice

    • Keep in sealed packaging until installation.

    • Store in dry, room-temperature environment.
