Tracking The Blade - Delta 28-278 Instruction Manual

These graduations are correct for average work, and will
not be affected by rebrazing of the saw blade. Use these
graduations until you become familiar enough with the
operation of the band saw to vary the tension for different
kinds of blades or work.
IMPORTANT: OVER-STRAINING IS A COMMON CAUSE
OF BLADE BREAKAGE AND OTHER UNSATISFACTORY
BLADE PERFORMANCE. RELEASE BLADE TENSION
WHEN THE TOOL IS NOT IN USE.

TRACKING THE BLADE

CAUTION: DISCONNECT TOOL FROM POWER SOURCE.
IMPORTANT: Before tracking the blade, check to see that the blade guides and blade support bearings do not
touch 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. 22 should travel in the center of the upper tire. If the blade creeps toward the front edge, loosen
the wing nut (C) Fig. 23, and tighten the thumb screw (D). This will draw 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 (D)
Fig. 23 only a fraction of a turn each time. NEVER TRACK THE BLADE WHILE THE TOOL IS RUNNING. After the
blade is tracking to the the center of both tires, tighten the wing nut (C) Fig. 23. Adjust the Blade Guides and
Bearings.

VERTICAL ADJUSTMENT OF THE UPPER BLADE GUIDE ASSEMBLY
1. CAUTION: DISCONNECT TOOL FROM POWER SOURCE.
2. Set the upper blade guide assembly (A) Fig. 24 as close as possible to the top surface of the workpiece. Loosen
the lock knob (B) and move the guide assembly (A) to the desired position.
3. Adjust the upper blade guide assembly so that the blade guides (A) Fig. 25 are parallel to the blade. To adjust,
loosen screw (B) and rotate the complete guide assembly (C) until the blade guides are parallel to the blade.
