Replace and reset the other three knives
in the same manner. All four knives are
set with the screws just snug back and
tighten the six screws against the slot
starting with the end screws first and then
the center screws until the knife is
securely held in the cutter-head. Tighten
the remaining three knives in the same

Replacing V-Belts & Adjusting V-
Belts Tension
CX15/CX20 planer is provided with three
V-belts from the motor to the cutter head,
in-feed and out-feed rollers through the
gear box.
To access the V-belts, remove the front
cabinet panel of the machine. If the V-
belts need to be replaced, raise the motor
to release the belt tension and then
replace them with a matching set of 3
belts.
To Adjust the V-belt, loosen the top motor
hex nuts and adjust the bottom hex nuts
to raise or lower the motor. If there is
approximately 3/4" deflection when a
moderate pressure is applied to the V-
belts, the V-belts are correctly tensioned.

Adjusting Roller Spring Tension
The spring tension should be adjusted so
that the work pieces move through the
planer properly
The roller tension varies depending upon
the type of wood you are planing. If the
stock consistently stops feeding during
the planing, the roller spring tension
should be increased and if the roller is
leaving indents in the wood as it leaves
the planer, the
decreased.
To adjust the roller
disconnect the planer from power and
adjust the #1, #2 and #3 cap screws as
shown in Figure 22, so that they protrude
1/8" and adjust the #4 cap screw so that it
protrudes 5/16" above the head casting.
