Return Spring Adjustment

The return spring is adjusted at the factory and
should not need further adjustment. If adjustment is
deemed necessary, follow the steps below while
referring to Figure 14:
1. Unplug the machine from the power source.
2. Loosen two hex nuts (A). Do not remove.
3. Firmly hold the coil spring cover (B).
4. Pull out the cover and rotate until the pin (C) on
the return spring plate engages the next notch in
the coil spring cover. Turn the cover clockwise to
decrease tension and counter-clockwise to
increase tension.
5. Tighten two hex nuts (A). Do not over-tighten. Nuts
should not contact the housing when tight. The hex
nuts should be tightened against each other.

Work Light (J-2500 and J-2530 only)

Install a light bulb, no larger than 60 watts into the
socket accessed from beneath the head. The rocker
switch controls the light switch (D, Fig. 14).
Table Tilt Adjustment
The table tilt adjustments are made on the table
bracket under the table.
To tilt the table (refer to Figures 15 and 16):
In the following steps do not
over loosen. This could result in the table
assembly to separate from the column, fall and
cause injury.
1. Loosen the socket head set screw (A) with a
3mm hex wrench.
2. Using a 15/16" wrench, loosen the hex cap
screw (B), and tilt the table to the desired angle
by aligning the arrow (C, Fig. 16) on the rotating
part of the bracket to the desired angle (in
degrees) displayed on the scale (D, Fig 16) at
the base of the bracket.
3. Tighten the hex cap screw (B).
4. Tighten the socket head set screw (A).

Operation

Installing Drills

Insert the drill into the chuck jaws about 1" (25.4mm)
long. When using a small drill do not insert it so far
that the jaws touch the flutes of the drill. Make sure
that the drill is centered in the chuck before
tightening the chuck with the key.

Using the Vise

For the small workpiece that cannot be clamped to
the table, use a drill press vise. The vise must be
clamped or bolted to the table. Always use a back-
up piece of scrap wood to cover the table. This
protects both the table and the drill bit.

Basic Operation

Place material to be drilled in such as way as to
come into contact with the left side of the column.
This prevents the material from spinning.
