MAINTENANCE
BRUSH REPLACEMENT
See Figure 20, page 23.
Externally accessible brush assemblies are located at the
right front and the left rear of the planer. These brushes
should be inspected every 10 to 15 operating hours for wear.
Replace both brushes when either brush has less than 1/4 in.
of carbon remaining.
NOTE: The dust hood may be removed for easier access
when removing the rear brush cap.

Unplug planer and remove the switch key.

Using a flat-head screwdriver, unscrew the brush cap.
NOTE:
The brush assembly is spring-loaded and will pop
out when you remove the cap.

Remove the brush assembly (brush and spring) and
inspect for wear. If less than 1/4 in. of carbon remains
on brush, replace both brush assemblies. Never replace
one side without replacing the other.

Install new brush assembly, if required, or reinstall old
brush assembly.

Replace cap and tighten to secure.
BLADE REPLACEMENT
See Figures 21 - 26, page 24.
WARNING:
Always wear heavy leather gloves and use caution when
loosening blade locking screws and handling and/or
changing blades. Blades are sharp and can cause seri-
ous injury.
The planer is equipped with replaceable/disposable double-
edged cutter blades attached to a rotating cutter head. Worn
cutter blades will affect cutting accuracy and may produce
ridges on the workpiece.
NOTE: The replacement blades may appear slightly different
than the original blades.
 Unplug the planer.

Lower the cutter head assembly to 1 in. height.

From the back of the planer, remove the screws holding
the dust chute in place.

Remove the dust hood screws holding the dust hood in
place.

Remove the dust hood and set aside.
WARNING:
To avoid injury, NEVER rotate the cutter head by hand.

If cutter head is not locked, rotate until it locks.
NOTE: Rotating the cutter head is accomplished by using
the blade wrench on one end until the cutter head locks
in place
.
NOTE: The cutter head lock will engage when the head
is rotated. The cutter head lock automatically engages
when the dust hood is removed. Do not operate thickness
planer without the dust hood in place or the planer will
be damaged.

Carefully loosen and remove the blade locking screws.

Using the magnets, remove the blade lock bar by placing
the blade wrench on blade, lifting slightly, then pulling
straight out.

Repeat above step to remove the blade.
NOTE: If you are changing to the second side of the blade,
rotate the blade “end for end” keeping the same flat side
down. This correctly positions the blade for reinstallation.

Using the magnets, align holes in blade with pins on cutter
head and push the installed blade in firmly. Check that
the blade edge is parallel to the cutter head slot.

Align blade lock bar over the blade then securely retighten
the blade locking screws.

Push and hold the cutter head lock down and rotate fan
slightly to unlock the cutter head.

Release cutter head lock and rotate the cutter head to
the next lock position to access the second blade.

Repeat the above steps for the third blade.

Replace the dust hood.
Dispose of used blades properly. Wrap blades in tape before
disposal to avoid accidental injury.
