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.
