Return Spring Adjustment
The return spring is located behind the left
downfeed handle hub. It is adjusted at the
factory and should not need further adjustment.
If adjustment is deemed necessary:
1. Unplug the machine from the power source.
Referring to Figure 9:
2. Remove Items A–G in that order. A 19mm
wrench is required to loosen the hex nut (B).
3. Loosen the two jam nuts (H, J). Do not
remove.
4. Pull out slightly the coil spring cover (M)
while firmly holding it. DO NOT allow the coil
spring cover to turn freely in your hand, or
the spring will unwind.
Figure 9
5. Rotate the coil spring cover (M) until the
notch on the cover engages with the tab (L)
on the head casting. Turn the cover clock-
wise to decrease tension and counter-
clockwise to increase tension.
6. Replace flat washer (G) and key (F).
7. Tighten hex nut (J) firmly by hand against
the cover (M), then secure by tightening the
jam nut (H) against the hex nut (J).
8. Reinstall the hub (E), flat washer (D) and
spring washer (C).
9. Reinstall and tighten jam nut (B).
10. Reinstall the hub cover (A).
Table Tilt Adjustment
Remove the alignment pin
first and then loosen the hex cap bolt. Failure
to comply may cause the table assembly to
separate from the column and fall.
To tilt the table (referring to Figure 10):
1. Turn nut (C) clockwise to pull out the
alignment pin (B).
2. Loosen hex cap screw (A), and tilt the table
to the desired angle.
3. Tighten the hex cap screw (A).
4. Reinsert the alignment pin (B).
Figure 10
The alignment pin only works at 90° and must
be reinserted when the table is returned to 90°.
