Setup And Adjustments; Removing The Chuck And Arbor; Adjusting The Depth Stop; Changing Spindle Speeds - Jet JDP-15M Operating Instructions Manual

Never do any works "freehand" (hand-
holding the work piece rather than
supporting it on the table), except
when polishing.
Support long workpieces with helping
roller stands.
Do not use wire wheels, router bits,
shaper cutters, circle cutters, or rotary
planers on this drill press.
Never cut magnesium-
high danger of fire!

7. Setup and adjustments

General note:
Setup and adjustment work may
only be carried out after the
machine is protected against
accidental starting by pulling the
mains plug.

7.1 Removing the Chuck and Arbor

Unplug the machine from the power
source.
Lower the quill using the down feed
handle.
Rotate the spindle to align the key in
the spindle with the key hole in the
quill.
Insert the drift key (A, Fig. 9) into the
aligned slots and tap lightly. Have
another person (or a protected table)
catch the chuck and arbor assembly
as it falls away from the spindle.
Fig 9

7.2 Adjusting the Depth Stop

To drill multiple holes at the same
preset depth, use the depth stop:
With the drill bit in the chuck, lower
the down feed handle to advance the
chuck to the desired point.
With your other hand, advance the
lock nuts (A, Fig. 10) on the depth
stop (B, Fig. 10) until they touch the
stop bracket.
Fig 10
The drill bit will now advance only to
this point.

7.3 Changing Spindle Speeds

Loosen the locking screw on the
pulley cover, then open the cover.
A spindle speed and belt arrangement
chart is found on the inside of the belt
cover (A, Fig. 11). Refer to this chart
whenever changing speeds.
Fig 11
To change spindle speeds:
Unplug the machine from the power
source.
Loosen two side bar bolts found on
each side of the head assembly. (A,
Fig. 12).
Fig 12

Rotate the tension adjuster (B, Fig.
12) to bring the motor base as close
to the head as possible.
Change the belts location according
the speed chart and the speed you
desire.
Rotate the tension adjuster (B. Fig.
12) to tension the belts.
Tighten two slide bar bolts (A, Fig.
12). Belts are properly tensioned when
finger and thumb pressure midway
between the two pulleys causes
approximately 10 mm deflection.
Close and lock the pulley cover.
7.4 Table Tilt Adjustment
Disconnect the machine from the
power source (unplug).
Remove the alignment pin (B, Fig. 13)
first by turning the nut (A, Fig. 13)
clockwise.
Fig 13
Loosen the hex cap bolt (C, Fig. 13) to
tilt the table.
Caution:
Only loosen the hex cap bolt slightly,
otherwise the table assembly will
separate from the column and fall.
Tighten the hex cap bolt.
The alignment pin only works at 90°
and must be reinserted when the table
is returned to 90°.
