Inspect Work Table Parallel To Cutterhead; Adjusting Work Table Parallel To Cutterhead (Fine Adjustment) - Jet JWP-15DX Operating Instructions And Parts Manual

Care must be exercised in setting knives into the
cutterhead. Replace all three knives at the same
time. Proceed as follows:
1. Disconnect machine from power source.
2. Remove the gib screws and the gib (Figure
17) using a T-handle hex wrench.
3. Remove old knife, and clean cutterhead slot
and gibs.
4. Install new knife, making sure the knife fits
properly over the two pins in the cutterhead
slot. Make sure the blade is oriented in the
proper direction. Use the provided magnet
tools to help safely position the knives.
5. Place the gibs evenly over the knife, and
insert and tighten the gib screws, beginning
at one end of the knife and working toward
the other end.
After installing knives, check
again carefully. Make certain all gib screws
are tightened securely. Loose knives can be
thrown from the cutterhead, causing injury.
Inspect Work Table Parallel to
Cutterhead
The work table is set parallel to the cutterhead at
the factory and no further adjustment should be
necessary. If your machine is planing a taper,
first check to see if the knives are set properly in
the cutterhead. Then check to see if the work
table is set parallel to the cutterhead. Proceed
as follows:
1. Disconnect machine from power source.
2. Place the gauge block (Figure 18) on the
work table directly under the edge of a knife
as shown. Make slight contact by gently
raising table.
3. Move the gauge block to the opposite end of
the work table. NOTE: Distance from the
work table to edge of knife should be the
same at both ends.
Adjusting Work Table Parallel to
Cutterhead (Fine Adjustment)
If the gap difference determined in the previous
section is greater than 0.004" and less than
0.016", perform the adjustment procedure as
follows:
1. Determine which side of the table must be
raised to correct the gap.
2. Locate the two socket head cap screws in
the table casting for each of the columns
(Figure 19). Loosen both sets of screws for
each column on the side you wish to adjust.
