Turn planer OFF and disconnect power before performing any
maintenance or adjustments!
The knife inserts on the 20” Planer are four-sided. When dull, remove each
knife, rotate it 90° for a fresh edge, and re-install it (52-60 in/lb.) . No further
adjustment is necessary. Use a Torx wrench (T25) to remove the knife insert
screw. Use a second Torx wrench to hold the cutterhead (from rotating) in
position (in another screw). DO NOT USE YOUR HAND TO HOLD THE
CUTTERHEAD! See Fig. 13.
It is advisable to rotate all inserts at the same time to maintain consistent
cutting. However, if one or more knife inserts develops a nick, rotate only those
inserts that are affected. Each knife insert has an etched reference mark so you
can keep track of the rotation. It is advisable to mark any knife with a nick with
a pen, for future reference.
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 jointer (52-60 in/lb.).
Make sure all knife insert screws are tightened securely. Loose inserts can be
propelled at high speed from a rotating cutterhead, causing injury
(52-60 in/lb.).
Conveying Rollers
Keep rollers clean to help prevent slippage of material.
