Blade Care
Blades are extremely sharp!
Use caution when cleaning
or changing. Failure to comply may cause
serious injury!
!
The condition of the blades will affect the
precision of the cut. Observe the quality of
the cut that the machine produces to check
the condition of the blades.
!
Dull blades will tear, rather than cut the
wood fibers and produce a fuzzy
appearance.
!
Raised grain will occur when dull blades
pound on wood that has varying density. A
raised edge will also be produced where the
blades have been nicked.
When gum and pitch collect on the blades,
carefully remove with a strong solvent. Failure to
remove gum and pitch build up may result in
excessive friction, blade wear and overheating.
When blades become dull, touch up blades. See
Sharpening the Knives.
Sharpening the Knives
Blades are extremely sharp! Use caution
when handling. Failure to
comply may cause serious
injury!
1. Disconnect the machine from the power
source.
2. Remove the blade guard and belt cover.
3. To protect the infeed table from scratches,
partially cover the sharpening stone with
paper (Figure 24).
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.
6. Keep the cutterhead from rotating by
grasping the cutterhead pulley while sliding
the stone back and forth across the table.
7. Take the same amount of passes for all two
blades.
When the blades have been sharpened and 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. It is recommended to keep a second set of
blades on hand so that they may be installed
while the first set is being professionally
sharpened.

Lubrication
!
Use a good grade of light grease on the
steel adjusting screws located in the raising
and lowering mechanisms of the work
tables.
The cutterhead ball bearings are lifetime
lubricated and need no further care.
