Factory or Field Procedure
1.Raise the saw head enough to allow the saw motor to operate.
2.Loosen four knobs securing the blade cover. Lift the cover and swing it backward.
3.Remove the blade guard mounted on the left blade guide support.
4.Remove both blade guide bearing brackets. NOTE: Maintain proper tension at all times using the
blade tensioning mechanism.
5.Loosen the center locking screws in all three hex adjustment screws on the blade tensioning mechanism (see figure 10).
CAUTION: WHILE PERFORMING THE FOLLOW- ING, KEEP THE BLADE FROM RUBBING EXCES- SIVELY ON THE SHOULDER OF THE WHEEL.
EXCESSIVE RUBBING WILL DAMAGE THE WHEEL AND/OR THE BLADE.
6.Start the saw. Slowly turn the single hex adjust- ment screw at the rear of the tracking mechanism to tilt the idler wheel. Do not turn either of the
other two adjustment screws. Turn the adjustment screw until the blade is touching the shoulder of the idler wheel.
NOTE: Turning the screw inward causes the blade to move toward the shoulder of the wheel. Turning the screw outward causes the blade to move away from the shoulder.
7.Turn the single hex adjustment screw so the blade starts to move away from the shoulder of the wheel — then immediately turn the single hex adjustment screw in the other direction so the blade stops, then moves slowly toward the shoul- der.
WARNING: KEEP FINGERS CLEAR OF THE BLADE AND WHEEL TO AVOID INJURY.
8.Turn the single hex adjustment screw to stop the motion of the blade on the wheel as it gets closer to the wheel shoulder. Put a
9.Turn the single hex adjustment screw a small amount. Repeat the insertion of the paper between the wheel shoulder and the blade until the paper is cut in two pieces.
NOTE: You may have to repeat the check with the paper several times before the blade and the shoulder cuts the paper into two pieces. Do not hurry the adjustment. Patience and accuracy here will pay off with better, more accurate, quieter cutting and much longer machine and blade life.
10.When the paper is cut, turn the hex adjustment screw slightly in the counterclockwise direction. This assures that the blade is not touching the shoulder of the wheel.
11.Shut off the saw.
12.Hold the hex adjustment screws with a wrench and tighten the center locking screws. Make sure the hex adjustment screws do not move while tightening the center screws.
13.Install the two blade guide bearing brackets. Position the guides so the bearings just touch the blade.
14.Install the left blade guard.
15.Close the saw head cover. Tighten the four knobs.
