Cutterhead Removal
The entire cutterhead assembly may be removed
for cleaning or for bearing and blade replacement.
Some woodworkers keep a spare cutterhead with
replacement blades should the original cutterhead
have to be repaired.
Blades in the cutterhead are
sharp! Use extreme caution
when handling the removal of the cutterhead.
Failure to comply may cause serious injury!
To remove the cutterhead (including bearings,
studs, and housing) from the base casting:
Referring to Figure 45:
1. Disconnect the machine from the power
source.
2. Remove the front blade guard (A) and
screw (B).
Lock the fence tilt lock handle
(D) to avoid injury from moving parts when
moving this assembly.
3. Remove the two lock nuts (G) and washer (F)
securing the fence assembly (C) to the fence
base casting (E).
4. Lift the fence assembly (C) from the table and
set aside.
5. From the left side of the stand, remove the
dust chute. From the back of the machine
remove the cabinet access door.
Referring to Figure 46:
6. Using an 8mm hex wrench, loosen two hex
cap screws underneath fence base casting (E)
that secure the casting to the table (F).
Remove the fence base casting and set aside.
7. Remove four screws and washers (A) securing
the belt guard (B). Remove the belt guard.
8. Using a 14mm wrench, remove two screws
(A, Fig. 47) and lock washers that secure the
cutterhead bearing housings to the base.
Note: These screws and lock washers are
more easily accessible through the dust chute.
9. Using a 3mm hex wrench, loosen two set
screws that secure the cutterhead pulley (D) to
the cutterhead shaft. Do not attempt to remove
pulley with belt at this time.
10. Slide the pulley from the shaft of the
cutterhead along with the V-belt. Set the
pulley, shaft key and V-belt aside.
