Replacing or Rotating Knife Inserts (Helical Cutterhead Only)
Knife inserts are sharp; use caution when working with or around them.
The knife inserts on the model
Use the provided star point screwdriver to remove the knife insert screw. See Figure 37a. It is advisable to rotate all inserts at the same time to maintain consistent cutting. However, if one or more knife inserts develop a nick, rotate only those inserts that are affected.
Each knife insert has an etched reference mark so you can keep track of the rotations.
IMPORTANT: When removing or rotating inserts, clean saw dust from the screw, the insert, and the cutterhead platform. Dust accumulation between these elements can prevent the insert from seating properly, and may affect the quality of the cut.
Before installing each screw, lightly coat the screw threads with machine oil and wipe off any excess.
Securely tighten each screw which holds the knife inserts before operating the planer!
Make sure all knife insert screws are tightened securely. Loose inserts can be propelled at high speed from a rotating cutterhead, causing injury.
Make sure the outfeed table is set level with the knife inserts (follow steps 1 through 5 on page 19).
Eliminating “Play” in Tables
There are four set screws at the front of the jointer – two on the outfeed table and two on the infeed table – that will allow you to prevent “play” in the tables. (Figure 38 shows one of the set screws for the outfeed table.)
After a period of use, the copper tip (see item #27, page 41) which is attached to the end of the set screw (A, Figure 38) may become loose. Resolve this as follows.
1.Loosen the hex nut (B, Figure 38) with a 14mm wrench.
2.Tighten the set screw (A, Figure 38) with a 5mm hex wrench. Do not overtighten the set screw, as it may prevent the table from being raised and lowered easily.
