Specifications include, but are not limited to: FORCEMATCH HD (FM02) DIAGNOSTIC WHEEL BALANCER OR EQUAL. Unit to be a Hunter Force Match Balancer, Model FM02 HD or Equal, to include the following minimum features: Smartweight technology or competitive equivalent Optimized dynamic wheel balancing technology that minimizes correction weight usage and maximizes productivity, by computing correction weight by measuring and evaluating the “absolute” static and couple forces that cause vibration. Smartweight balancing evaluates static and couple forces independently, applies separate tolerance limits, and then computes correction weights based on vibration force reduction, not fixed weight tolerances. Bottom Dead Center (BDC) laser correction weight placement locator. BDC weight placement lasers guide the operator to the precise top-dead-center locations for corrections weight placement. Hammerhead (or competitive equivalent) Top Dead Center (TDC) laser correction weight placement locator: TDC weight placement lasers guide the operator to the precise top-dead-center locations for correction weight placement.
