Adjusting Blade Tension

1) Disconnect machine from power source.
The blade tension knob (A-Fig.6)) is used to adjust blade tension.
Note: All bearings on upper and lower guides must be clear of blade.
2) Apply just enough tension to take the slack out of the blade.
3) Turn one wheel a few times to allow the blade to position itself in the center of the tire.
Note: If blade does not center see Adjusting Blade Tracking section (this page).
A scale (D) directly behind the upper wheel (E) indicates the approximate tension according
to the width of the blade.
4) Set the blade tension with knob (A) to correspond to the blade width as marked on the
gauge (D).
Note 1: Changes in blade width and the type of material being cut will have an effect on blade
tension.
Note 2: Keep in mind that too little or too much blade tension can cause blade breakage.
