10.The tightening process should continue at least two more times, each time tightening the screws more on all three knives. On the third time, they should all be firmly tightened.
Before starting the jointer, make sure all gib screws are firmly tightened. A loose knife thrown from the cutterhead can cause severe or fatal injury.
11.After replacing knives, the outfeed table must be checked and adjusted so that it is level with the high point of the knives. See “Setting Outfeed Table” on pages
Replacing and Rotating Knife Inserts
(Helical Cutterhead Only)
Knife inserts are extremely sharp; use caution when working with or around them. Disconnect power.
The knife inserts on the model
Two
Each knife insert has an etched reference mark so that you can keep track of 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 may be propelled at high speed from a rotating cutterhead, causing injury.
Make sure the outfeed table is set level with the knife inserts See “Setting Outfeed Table” on page
