4.If the reading on the tension tester is less than the range shown in the table, the belt is too loose and must be tightened. If the reading is greater than the range shown in the table, the belt is too tight and must be loos- ened. Adjust the belt until the reading falls within the acceptable range in the table.

Belt Tension Measurements
1.Place a straight edge along the top edge of the belt to be tested so that it spans both pulleys. Place the tension tester in the center of the belt and press and down on the cap until the lower
2.Read the setting of the upper
3.Compare this value with the acceptable range in the appropriate table. If the belt is brand new (has never been run), use the range in the In- itial Tension column. If the belt is not brand new, locate the accept- able range in the Final Tension column.
