TRACKING THE BLADE
CAUTION: DISCONNECT MACHINE FROM POWER
SOURCE.
IMPORTANT: Before tracking the blade, make sure that
the blade guides and blade support bearings are clear of
the blade.
After applying tension to the blade, rotate the wheels
slowly forward by hand and observe the blade’s
movement. The blade (A) Fig. 31 should travel in the
center of the upper tire. If the blade creeps toward the
front edge, loosen the wing nut (B) Fig. 32, and turn the
thumb screw (C) clockwise. This action draws the blade
toward the center of the tire. If the blade creeps toward
the back edge, turn the thumb screw in the opposite
direction. Adjust the thumb screw (C) Fig. 32 only a
fraction of a turn each time.
NEVER TRACK THE
BLADE WHILE THE TOOL IS RUNNING . After the
blade is tracking in the center of the tires, tighten the
wing nut (B) Fig. 32.

ADJUSTING THE UPPER BLADE GUIDES
AND BLADE SUPPORT BEARING
Adjust the upper blade guides and blade support bearings ONLY AFTER the blade has the correct tension and is
tracking properly. To adjust, do the following:
1. DISCONNECT MACHINE FROM POWER SOURCE
2. Make sure that the bottom blade guides and support bearings are not touching the blade.
3. Check the upper blade guide assembly. The blade guides (A) Fig. 34 should be parallel to the blade. To adjust,
loosen the screw (B) and rotate the complete guide assembly (C). When the blade guides are parallel with the blade,
tighten the screw (B).
4. Adjust the guides (A) Fig. 35 so that the front edge of the guides are just behind the “gullets” of the saw teeth. The
complete guide block bracket can be moved in or out by loosening the thumb screw (C) and turning the knurled knob
(D) Fig. 35. When the guides (A) are set properly, tighten thumb screw (C).
