Measure the tension of the belt that is farthest from the engine.
(1) Belt tension “Initial” is for a new belt.
(2) Belt tension “Used” is for a belt that has operated for 30 minutes or more of operation at the rated speed.
(3) If a belt falls below the “Used” belt tension, the belt should be tightened again to the high side of the “Used” belt tension.
