Notes

Notes		The recommended angle of pretension is 20°. This provides the tensioner a maximum capability to absorb vibrations and shock loads, while also maintaining a range of motion to address the system’s belt or chain stretch. Mounting accessories into the “Hard” Position results in approximately 25% higher tensioning force over the “normal” position. Metric standard tensioner units all come with a mounting screw, but do not come with the sprocket idler bolt (which is supplied instead with RunRight metric idler sprockets).
