Gib Adjustment; Power Feed Operation; Adjusting The Spindle Return Spring - Jet JMD-15 Owner's Manual

Gib Adjustment

After a period of time, movement of the table
over the ways will cause normal wear. To adjust
the gibs for this wear:
1. The horizontal gib adjustment screw (A, Fig.
13) is found to the right on the table face.
The traverse gib adjustment screw (B, Fig.
13) is found on the right side of the saddle
under the table.
2. Turn each screw slightly clockwise to tighten.
Turn the table hand wheels and check the
tension.
3. Re-adjust as required.
Power Feed Operation (JMD-18PFN only)
Make all power feed settings
with power to the machine turned off. Failure
to comply may cause damage to the machine.
1. Set the power feed speed range dial (C, Fig.
14) to the desired rate.
2. Set the depth stop to the desired setting by
lowering the quill to the desired depth and
holding in place. Turn the collar (D, Fig. 14)
counter-clockwise until zero is indicated and
then tighten the lock handle (E, Fig. 14)
3. Start the mill/drill and pull one of two handles
(F, Fig. 14) away from the column to start
the power downfeed.
4. Once the downfeed has reached the depth
stop, the trip will release and the spindle will
retract.
5. To stop the feed before the cycle has ended
or to disengage the fine feed (G, Fig. 14),
press one of two handles toward the column.

Adjusting the Spindle Return Spring

factory and should not need any adjustment.

(H, Fig. 15).
2. Loosen knob (I, Fig. 15) just enough to
rotate spring cap past the notch (J, Fig. 15).
3. Rotate the spring cap clockwise to decrease
spring tension.
counter-clockwise to increase spring tension.
