8" HELICAL CUTTERHEAD
ASSEMBLY FOR G0855
INSTRUCTIONS

Jointer knives are extremely sharp. You
must remove the jointer knives, or mount
the knives blade side down to avoid the risk
of serious personal injury during the follow-
ing steps.

1– 4.

5. Remove nut and flat washer on bearing block
stud, as shown in Figure 3, and repeat on the
other side.
6. Wearing heavy leather gloves, carefully
remove the cutterhead from the casting (see
Figure 4).
Note: Your cutterhead may have paper shims
stuck to the bearing block or where the bear-
ing block rests. These were included at the
factory when they calibrated your cutterhead
to be even with the outfeed table. Your new
cutterhead may or may not need these. If
you see any shims, carefully pull them off
and set them aside for later use—or keep
them with your cutterhead in the event that
you re-install it later. Also, mark the side of
the cutterhead where they were used, so the
future install will go smoothly.
7. Remove bearing block studs from bearing
blocks.
Removing Existing Cutterhead
1. DISCONNECT MACHINE FROM POWER!
2. Remove jointer fence, cutterhead guard, and
rabbeting table.
3. Remove rear access panel and belt cover,
then remove V-belt from pulleys.
4. Lower both tables to make enough room for
the cutterhead to come out (see Figure 2).
Note: When lowering, make sure that the
fence support does not come in contact with
the cutterhead pulley.

Jointer carbide inserts are extremely sharp.
Wear leather gloves to avoid the risk of
serious personal injury during the following
steps.

Installing Helical Cutterhead
1. Install cutterhead (see Figure 5) with bearing
block studs, flat washers, and hex nuts previ-
ously removed.
2. Tighten helical cutterhead in place, and
ensure pulley set screw is tight.
3. Using straightedge and feeler gauge set,
inspect cutterhead parallelism with outfeed
table as shown in Figure 6. With straightedge
in position, raise or lower outfeed table until
cutterhead body (not the carbide insert) just
touches straightedge.
4. Move straightedge to the other side to deter-
mine if one end of cutterhead body is higher/
lower than the other. (Place feeler gauge
between cutterhead body and straightedge to
determine the height difference.)
— If cutterhead is even or within 0.003" with
outfeed table from one side to other, skip
to Step 7.
— If cutterhead is over 0.003" from one side
to other, go to Step 5.
5. Loosen hex nuts securing both bearing block
studs, lift helical cutterhead slightly, then
place a shim beneath bearing block that
needs to be adjusted.
Note: Use shims from your old cutterhead
if available. If not available, newspaper is
approximately 0.003" thick and will work for
shimming (we don't recommend shimming
more than 0.003" on either side, as this may
affect how the bearing block seats in the
casting).
6. Repeat Steps 3–5 and adjust as necessary,
then tighten hex nuts on bearing block studs.

7. Place a straightedge on outfeed table
so it extends over cutterhead, and rotate
cutterhead pulley until one of the carbide
inserts is at top-dead-center (TDC), as shown
in Figure 7.
8. Lock outfeed table, then re-install fence.
9. Re-install V-belt on pulleys. (Refer to instruc-
tions in your G0855 manual for details.)
10. Re-install rabbeting table, rear access panel,
and belt cover.
11. Install cutterhead guard back over cutterhead,
making sure that spring tension in guard
is properly set so guard springs back over
cutterhead when it is pulled back and
released.
When correctly set, carbide insert will just
touch straightedge when insert is at its high-
est point of rotation (see Figure 7).
— If your outfeed table is correctly set, no
adjustments are necessary.
— If insert lifts straightedge off table or if
table is below straightedge, adjust outfeed
table height with handwheel until straight-
edge just touches an insert at its highest
point of rotation.

Installing or adjusting a carbide insert:
1. DISCONNECT MACHINE FROM POWER!
2. Remove any sawdust from head of carbide
insert Torx screw.
3. Remove Torx screw and carbide insert.
4. Clean all dust and dirt off insert and cutterhead
pocket from which insert was removed, and
replace insert so a fresh, sharp edge is facing
outward.
Note: Proper cleaning is critical to achiev-
ing a smooth finish. Dirt or dust trapped
between insert and cutterhead will slightly
raise insert, and make noticeable marks on
your workpieces the next time you cut.
5. Lubricate Torx screw threads with a light
machine oil, wipe excess oil off threads, and
torque Torx screw to 48-50 INCH pounds.
Note: Excess oil may squeeze between insert
and cutterhead or in screw hole, thereby lifting
insert or screw slightly and affecting work-
piece finishes.
In addition, each insert has a reference dot on
one corner. As the insert is rotated, the reference
dot location can be used as an indicator of which
edges are used and which are new. The insert
must be replaced when all four edges are dull.
Rotating Inserts
The cutterhead is equipped with 36 indexable car-
bide inserts. Each insert can be rotated to reveal
any one of its four cutting edges. Therefore, if one
cutting edge becomes dull or damaged, simply
rotate it clockwise 90˚ to reveal a fresh cutting
edge (see Figure 8).
