TRACKING THE BLADE IMPORTANT:
Before tracking the blade, make sure the blade guides and blade
support bearings are clear of the blade so as not to interfere with
the tracking adjustment.
After tension has been applied to the blade, revolve the wheels
slowly forward by hand and watch the blade (A) Fig. 14, to see that
it travels in the center of the upper tire. If the blade begins to creep
toward the front edge, loosen the wingnut (B) and tighten the
thumbscrew (C). This will tilt the top of the wheel toward the back of
the machine and will draw the blade toward the center of the tire. If
the blade creeps toward the back edge, turn the thumbscrew in the
opposite direction. Adjust the thumbscrew (C) only a fraction of a
turn at a time. NEVER TRACK THE BLADE WHILE THE
MACHINE IS RUNNING. After the blade is tracking in the center of
the tires, tighten the wingnut (B) Fig. 14.
ADJUSTING UPPER BLADE GUIDE ASSEMBLY
The upper blade guide assembly (A) Fig. 15, should always be set as
close as possible to the top surface of the material being cut by
loosening thumbscrew (B) and moving the guide assembly (A) to the
The upper blade guide assembly should also be adjusted so that the blade
guides (A) Fig. 16, are flat with the blade. If an adjustment is necessary,
loosen screw (B) and rotate the complete guide assembly (C) until the
blade guides are flat with the blade.
