W1747 20" Planer
Setting/Replacing Knives
Setting the knives correctly is crucial to the proper operation of the planer and is very important in keeping the knives sharp. If one knife protrudes higher than the others, it will do the majority of the work, and thus, dull much faster than the others.
The included knife gauge is designed to set the knives approximately 0.040" higher than the cutterhead. Planer Pal® (Model W1216) can also be used to set the knives.
This planer comes with both jack screws and springs to provide you with two options for cutterhead adjustments (see Figure 18).
Note: Only one of these options is needed to set the
To set the knives, do these steps:
1.DISCONNECT THE PLANER FROM THE POWER SOURCE!
2.Remove the top cover and dust port.
3.Remove the belt guard to expose the cutterhead pulley.
4.Rotate the cutterhead pulley to give you good access to one of the knives.
Planer knives are dangerous and may cause personal injury. To reduce the risk of beng injured, wear leather gloves when handling the knives in the fol- lowing steps.
5.Using a 12mm wrench, loosen the cutterhead gib bolts, starting in the middle, and alternating back and forth until all of the gib bolts are loose, but not falling out.
Note: If this is the first time you are setting the knives, remove the gib and knife from the cutterhead. The cutterhead comes with both springs and jack screws installed. Decide which adjust- ment option you are going to use. If you decide to use the jack screws, remove the springs from the cutterhead. If you decide to use the springs, you can just thread the jack screws completely into the cutterhead so they will not get lost. Replace the gib
and knife.
