Rite Tensioning Device®
Calibrating the WELLSAW RITE-TENSION ® Blade Tensioning Device
The Rite-Tension® device is a simple turn counter that is activated by blade tension and can be easily adjusted in the field.
Please review the operation instructions before making any adjustment:
1. LOOSENING
When replacing a worn or broken blade always turn the "T" handle out at least six (6) turns (counter-clockwise).
This will reset the device. Always push-in on the handle when loosening, this will insure that the internal counter is engaged.
2. TIGHTENING
Always pull out on the "T" handle when tightening the device (clockwise). After a number of turns the "T" handle will come
to a hard stop.
At this point the blade will be properly tensioned. Do not force the unit beyond this point.
Note: If the mechanism does not seem to come to a hard stop but continues to tighten, stop and repeat steps one and two.
Check to make sure the blade is properly positioned on the band wheels and is not binding in the guides during the
tightening process.
Calibration
The final tension is determined by the Adjusting Nut, pn 150070 (see "A" in drawing). The "rough" position can be
checked by measuring the clearance between the nut and the Tensioning Housing, pn 150067, (see "C").
A clearance of 1/4" will be within a safe range of the correct tension. When a tension guage becomes available the device
should be calibrated as follows: Loosen the set screw (B) one turn.
-If the band tension needs to be increased the adjusting nut should be turned out, one flat at a time, then the set
screw tightened and the device rechecked.
-If the tension needs to be decreased the adjusting nut should be turned in, one flat at a time and rechecked.
The device must be in the "loosened" or "open" position to make this adjustment.
