Backlash Adjustments For Blade Raising And Blade Tilting Mechanisms - Delta 36-477 Instruction Manual

BACKLASH ADJUSTMENTS FOR BLADE RAISING
AND BLADE TILTING MECHANISMS
After a period of extended use, if any play is detected in
the blade raising or blade tilting mechanisms, the follow-
ing adjustments should be made.
1. Make certain the machine is disconnected from
the power source.
2. NOTE: The machine has been turned upside down
and the blade removed for clarity and safety.
3. Adjusting blade raising mechanism - Loosen lock-
nut (A) Fig. 101, and turn eccentric sleeve (B) until all play
is removed in mechanism and tighten locknut (A).
4. Adjusting blade tilting mechanism - Loosen lock-
nut (C) Fig. 101, and turn eccentric (D) until all play is
removed in mechanism and tighten locknut (C).
CHECKING BLADE ALIGNMENT
1. Disconnect the saw from power source.
2. Raise blade guard and adjust blade to its highest
position. Mark one side of one saw blade tooth (F) with a
dark colored marker Fig. 101A. Rotate the blade toward
the front of the saw by hand until the marked tooth is at
the top of the table.
3. Insert the miter gage into miter gage slot and posi-
tion near the front edge of the blade. With a combination
square (G), place the straight edge along the face of the
miter gage. Position the end of the straight edge (H) to
lightly contact the side of the marked tooth.
4. Firmly hold the straight edge in place while rotating
blade marked tooth to the rear side of the table. Firmly
holding the straight edge in place, re-position the miter
gage to the rear side of the saw table Fig. 101B . Rotate
the blade with marked tooth (F) to end of straight edge to
check blade alignment gap. The marked tooth (F) should
be about the same distance from the end of the straight
edge in front and rear positions.
5. Repeat this procedure moving from front to rear until
you have visual confirmation of the blade alignment.
NOTE: All saw blades have some run-out, therefore, you
may need to check the alignment each time a blade is
changed.
6. If the blade alignment is off by .010 or the approxi-
mate thickness of a standard business card, follow
(ADJUSTING BLADE ALIGNMENT) procedure.
7. Lower blade guard and saw blade before reconnect-
ing power source.
