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)
Caution
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
The spindle return comes pre-set from the
factory and should not need any adjustment.
1. You do not want to remove the spring cap
(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.
Rotate the spring cap
counter-clockwise to increase spring
tension.
