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.

Outfeed Infeed

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.

T32057 8" Helical Cutterhead Assembly -5-

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).
