HOW TO USE？

1. CAUTION:Before doing maintenance or tensioning on belt drives,turn equipment off and lock outthepowersource.Use guards on machinery when running.

Place amatchedsetof belts over the sheave grooves.Take up the slack untilthebeltsappear fairly taut.

2. With the drive sped,measure the belt span lenth of yourdrive(seesketch).Set the rubber O-ring on the body of the tensiongaugeat thedimension equal to 1/64 inch ×32,1/2 inch.

3. Set the O-ring on the plunger at 0 against the body ofthetensiongauge.

4. With the tension gauge perpendicular to the span,apply a forcetoabelt in the center of the span.Deflect the belt until bottomofthelarge O-ring is even with the of the next belt,or thebottomofa straight edge laid across the of

 other belt(s)onthedrive.Release pressure and read pounds of force used atO-ringonplunger.

Note:When new belts are installed on a drive,the tension willdroprapidlyduring the first few hours.Thus,for new belts,tightentothe initialinstallation defection force shown in thetablesbelow.Check tensionfrequently during the first 24 hoursofoperation.Subsequentretensioning should fall between theminimumand maximum forces shownin the tables.

5. Compare the force required in step 4 with the ranges inthetablesbelow.

Tightenorloosenbelts to bring them into the recommened range.

Note:The proper tension for V-belt drive is the lowest tensionatwhichthe belts won’t slip under peak load condition
