Tracking The Blade; Blade Guide Assembly; Adjusting Tightness Of Anti-Drop Screw - Delta 28-276 Instruction Manual

TRACKINg THE BLAdE

disconnect the machine from the power source!
IMPORTANT: Before tracking the blade, confirm 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 machine
is running.
After the blade is tracking in the center of the tires,
tighten the wing nut (B) Fig. 32.
