Specification: The heavy magnetic measuring instrument is installed on the hub or brake rotor, which can quickly and accurately measure outboard tilt and main wind angle. The large adjustment knob can easily bubble the air to zero when the angle of inclination is measured. Graduate of +5 ° to -5 ° Calibration Magnetometer Note: Before you start check the external tilt angle, first use one of the following methods of the school cubic meter: install the horizontal cross section level with good quality; to make the long surface vertically. Place the meter's magnetic surface on the vertical surface of the horizontal meter and adjust the meter's finger rotor screw to make the bubbles at the center of 0°. Find out the outward tilt of the meter. The wheel After removing the the wheels and the same height of the sill plate as the height of the installation wheels, the vehicle is located (ensuring that reasonable steps have been taken to repair the vehicle, take the books, etc.) and use the Jack to carefully lift the crotch bone to the same height as the wheels. Check the external inclination with wheels Park the vehicle outside. the flat surface; all inflatable tires the correct pressure and block the rear wheels. After unloading entire hub cover, place a straight post on the plane of the two wheels until 6 hours. Repeat the above process for another center. Note: Before any adjustment, please check the user manual.
