W1754 20" Planer With Mobile Base
Setting/Replacing Knives
Setting the knives correctly is crucial to the proper opera- tion of the planer and is very important in keeping the knives sharp. If one knife protrudes higher than the oth- ers, it will do the majority of the work, and thus, dull much faster than the others.

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.
