9-5.ADJUSTING BLADE TENSION AND BLADE
TRACKING
To tension the blade, turn the blade tension handle (A) (fig. 7)
clockwise. A pointer and tension scale (B) is located underneath
the wheel. The scale is graduated to indicate blade tension of
20,000, 30.000 and 35,000 pounds per square inch (psi). For
carbon blades, the blade should be tensioned at 20,000 psi. For
bi-metal blades (similar to the one supplied with the machine), the
blade should be tensioned at 30,000 or 35,000 psi. Always release
blade tension at the end of each working day to prolong blade life.
Make sure the blade is tensioned correctly before checking or
adjusting tracking. The blade is tracking properly when the back of
the blade is just lightly touching the wheel flanges of both wheels
while the machine is running. If the blade is not touching the
wheel flanges, tighten or loosen screw C (fig. 7) until the blade tracks properly.
9-6.ADJUSTING CUTTING WIDTH
First loosen clamp knob (A) (fig. 8). Move the left blade guide bar to the suitable position. Then tighten clamp
knob (A).

9-7.ADJUSTING BLADE GUIDE ROLLER BEARINGS, CARBIDE BLADE GUIDES AND
BACK-UP BEARINGS AND CLEARING THE CUTTING CHIP
Before making the following adjustments, make sure the blade is
tracking and tensioned properly:
1. The back of the blade (A) (fig. 9) should F
ride against the back-up bearing (B).
To adjust, loosen set screw (C) and move E
the guide block (D) up or down, until it lightly
touches the back of the blade.
