Inspecting Knives
The planer knives are preset at the factory to surface me- dium to hard density wood when cutting 1/16" to 1/8" depths depending upon the width of the stock. Planer knives need to be periodically inspected for nicks and wear. Planer knives should be set approximately .070" above the cutterhead. To inspect and remove the knives for sharpening follow the steps below.
To inspect the knives:
1Disconnect the planer from the power source.
2 Remove the cover and dust chute. (Fiqure 22)
3 CAUTION! Planer knives are sharp be careful.
4Inspect the knives for nicks and excessive wear and sharpen or replace if necessary.
5To inspect the knives for proper height, place the knife gauge (Figure 23) over the cutterhead with the legs rest- ing flush to the cutterhead. The knives should lightly contact the middle tab of the knife gauge and should not rock. Check all 3 knives left and right sides. (Fig 24)
6If knives need adjusting or to be replaced follow the set- ting and replacing knives procedures.
Setting/Replacing Knives
NOTE: It is crucial to safety and planning results that the knives are sharp and correctly set. If one knife protrudes higher than the others, it will do the majority of the work, and produce poor results.
To set or replace the knives:
1Disconnect the planer from the power source.
2 Remove the top cover and dust chute.
3 Remove the belt guard to expose the cutter head pulley.
4 Rotate the cutter head pulley to give you good access to one of the knives.
5 Loosen the cutter head gib bolts slightly, starting at one end moving across to the other side alternating back and forth until they are all loose.
