1. Hold the hex cap screws (A1) in place with one wrench while using the other to
loosen the locking hex nuts.
2. Adjust the screws (A1) slightly from 1/8 to 1/4 turn. A counterclockwise turn will
raise the table; a clockwise turn will lower the table. Adjusting the right screw will
have greatest adjustment impact to the table's right side; adjusting the left screws
will have greatest adjustment impact to the table's left side.
3. hen adjustment is complete, secure by tightening the hex nut while maintaining
the position of the screw with the second wrench. It may be necessary to repeat the
exercise in this
section more than once to achieve co-planar alignment.
Note:
If the tables do not lock properly after the adjustment, see Jointer able Lock
Handle Adjustment on page next.
Setting Cutterhead Knives
Important :
Before performing any adjustments in this section, the infeed and outfeed
tables must be coplanar.
Cutterhead knives are dangerously sharp! Use extreme caution when inspecting,
removing, sharpening or replacing knives into the cutterhead. Failure to comply
may cause serious injury
1. Disconnect machine from the power source.
2. emove the cutterhead guard (B, Fig. 8). eferring
to Figures 11 and 12:
3. Carefully number each knife blade (C) with a
magic marker to differentiate each.
Note:
o rotate the cutterhead the cutterhead pulley
must be turned. his requires removing the panel on
the back of the cabinet for access.
4. otate the cutterhead (E) and determine the 12
o'clock position of knife number one. he 12 o'clock
position is the highest point a blade will reach in the
cutting arc (C, Fig. 12).
5. et a straightedge (J) on the outfeed table (F)
near the fence (H). One end of the straightedge
should be positioned over the cutting knife (C) near
the end of the blade as shown in Fig. 9.
Replacing or rotating knife inserts (helical cutterhead only)
The knife inserts on the model TJ-X300C are four-sided. When dull, simply
remove each insert, rotate it 90° for a fresh edge, and re-install it. Use the
provided star point Torx screwdriver to remove the knife insert screw. It is advisable
to rotate all inserts at the same time to maintain consistent cutting. However, if one or
more knife inserts develops a nick, rotate only those inserts affected. Each knife insert
has an etched reference mark to keep track of the rotations. An extra set of 5 knife
inserts and knife insert screws are included with your TJ-X300C.
IMPORTANT: When removing or rotating inserts, clean saw dust from the
screw, the insert, and the cutterhead platform. Dust accumulation between these
elements can prevent the insert from seating properly, and may affect the quality
of the cut. Before installing each screw, lightly coat the screw threads with
machine oil and wipe off any excess. Excess oil & grease can in and on threads of
screws and in cutterhead holes, can prevent the screws being correctly tightened and
the blade from being seated correctly.
Securely tighten each screw which holds the knife inserts before operating the
planer. Knife inserts should be torqued to approximately 50 to 55 inch-pounds. Make
sure all knife insert screws are tightened securely. Loose inserts can be propelled
at high speed from a rotating cutterhead, causing injury.
