Start-Up
5. Remove the belt tension gauge. The small O-ring now indicates a number other than zero on
the plunger’s force scale. This number represents the force (in pounds) required to give the
needed deflection.
6. Compare the “force” scale reading (Step 5) with the appropriate “force” value listed in Tab le 8 .
If the “force” reading is outside the range, readjust the belt tension.
Note: Actual belt deflection “force” must not exceed the maximum “force” value shown in
7. Recheck the belt tension at least twice during the first 2 to 3 days of operation. Belt tension may
decrease until the new belts are “run in”.
