W1747 20" Planer

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

knives—see Step 5 for clarification.

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.

Setting/Replacing Knives

Figure 18. Cutterhead profile diagram.

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.
