3. The cutterhead ball bearings are lifetime
lubricated and need no further care.

Blades are extremely sharp!
Use caution when cleaning or changing.
Failure to comply may cause serious injury!

Sharpening the Knives (JJ-8CS only)
When blades become dull, touch up blades.
1. Disconnect the machine from the power
source.
2. Remove the fence, blade guard and belt
cover.
3. To protect the infeed table from scratches,
partially cover the sharpening stone with
paper. (Fig. 33)
paper. (Fig. 33)

4. Lay the stone on the infeed table.
5. Lower the infeed table and turn the
cutterhead by turning the cutterhead pulley.
The infeed table height is set properly when
the stone’s surface is flush with the knife
bevel.

7. Take the same amount of passes for all
three blades.
When the blades have been sharpened, if they
still are not cutting efficiently, trying to touch up
the blades further will only cause the formation
of a second beveled edge. When this starts to
happen, it is time to replace blades with another
set.

while the first set is being professionally
sharpened.
