How to Install the S2MRB Suspension System

This guide provides step-by-step instructions for mounting and configuring the S2MRB suspension system for optimal performance.

Estimated time: 1h

Tools needed:

Screwdriver, Torque wrench, Multimeter

Supplies needed:

Mounting screws, Gaskets, Retaining washers

  1. Mount the tube

    Secure the round tube to the mounting bracket using 6 M12 screws. Ensure the screws are tightened to a torque of 20 Nm and that the gasket is pressed flat during installation.

  2. Align the tube

    Adjust the tube's position to ensure it is level. Slacken off screws 3 and 4, then tighten screws 1 and 2. Finally, re-tighten screws 3 and 4 while ensuring the gap does not exceed 4.4 mm.

  3. Secure the enclosure

    Attach the enclosure to the tube using 4 M6 screws and retaining washers. Tighten each screw to a torque of 6 Nm to ensure a secure fit.

  4. Calibrate the system

    Adjust the tilt angle limiter by unscrewing the cover and setting the desired inclination. Tighten the threaded sleeve to secure the angle.

  5. Verify connections

    Use a multimeter to check all electrical connections for continuity and proper voltage levels to ensure the system is functioning correctly.
