Setting the height of the knives correctly is cru-
cial to the proper operation of your 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, dull much
faster, and produce poor cutting results.
The knife gauge that is included with the Mod-
el is designed to set the knives 0.059" higher
than the cutterhead surface.
NOTE: If you need to replace or sharpen a
knife, you can remove the knife from the cut-
terhead during Step 4 of the following proce-
dure. Thoroughly clean out any debris from
the knife slots before replacing the knives.
Tools Needed: Hex wrench 2.5 mm, 10 mm
wrench (CE1115). 3mm Hex wrench and 12 mm
wrench (CE1120A). Knife Gauge.
TO ADJUST THE HEIGHT OF THE KNIVES:
1. DISCONNECT PLANER FROM POWER!
2. Remove the dust hood and the top cover to
expose the cutterhead.
3. Remove the belt cover, then rotate the cut-
terhead pulley to give you good access to one
of the knives.
NOTE: The cutter-
head for the Model
CE1120A ships with
both springs and jack
screws to adjust the
knife height (see fig-
ure 19)—which one
you use is up to your
personal preference.
However, you should remove the components
that you will not use from the cutterhead be-
fore proceeding.
4. If you have not al-
ready done so, loosen
the cutterhead gib
bolts until the knife
is completely loose,
then position the
knife gauge over the
knife so that the knife
edge is directly under
the center pad, as
shown in figure 20.

5. Jack Screws (CE1115
& CE1120A): Insert the
hex wrench into the
jack screws through
the access holes in the
cutterhead (see figure
21).
Rotate the jack screws to raise or lower the
knife until it barely touches the center pad of
the knife gauge with all legs of the gauge still
firmly on the cutterhead, then snug the gib
bolts enough to hold the knife in place.
Springs (CE1120A Only): Push down on the
knife gauge until all legs of the gauge are firm-
ly on the cutterhead and the knife just touches
the center pad of the gauge, then tighten the
gib bolts enough to hold the knife in place.
6. Slightly tighten the gib bolts, starting at the
middle and working your way to the ends by
alternating left and right, as illustrated in fig-
ure 22.
7. Repeat Step 6.
8. Repeat Step 6, but final tighten the gib bolts.
9. Repeat Steps 4–8 for the rest of the knives.
V-BELT TENSIONING/ REPLACEMENT
NOTE: After the first 16 hours of use, the V-
belts will stretch and seat into the pulley
grooves. The V-belts must be properly re-ten-
sioned after this period to avoid severely re-
ducing their useful life.
Three cogged V-belts transfer power from the
motor to the cutterhead, and then to the in-
feed and outfeed rollers with the use of the
drive chain system. To ensure efficient trans-
fer of power to these systems, make sure the
V-belts are always properly tensioned and in
good condition.
If the V-belts are worn, cracked, or damaged,
replace them. Always replace the V-belts with
a matched set of three, or belt tension may not
be even among the belts, causing premature
belt failure.
Tools Needed: Phillips Screwdriver. Wrench
19mm.
