3 Read tension on the dial face, across from the indicator on the
gauge body.
4 If the belt tension is within manufacture's specifications, seat
the belt. Run the machine for approximately 1-2 minutes and then
re- check the tension. This will allow the belt to seat itself in
the grooves of the pulley, and ensure tension is set correctly.
If the tension is not set to the manufactures specifications, remove
the tension gauge and adjust the belt tension. Repeat steps 1 through 4
until specifications are met.
