CHECK AND REPLACE THE BLADES
Refer to Figure 9 and 10
• Locate the blade cover on the back of planer. Loosen
and remove thumb screws from blade guard.
• Identify the cutterhead inside. Watch for TWO sharp
blades on the cutterhead.
• Without touching the blades, carefully turn the
cutterhead until it stops by the self-engaging latch.
• Use T Wrench to remove 6 bolts on the blade
assembly.
• Attach 2 provided magnets to the gib and carefully
remove it.
• Attach 2 provided magnets to the blades and carefully
remove it.
• Check to see if the blade is dull, worn, nicked, torn, and
uneven. These can result in poor performance such as
fuzzy grain, chipped grain, raised grain, raised edge,
and uneven cut.
• Replace with new blades in pairs only. Never mix new
blade with old blade on the cutterhead. Never mix
blades with different degrees of wear. Never use a
blade where unbalanced wear from side to side is
present.
• To replace with the new blade, use the 2 provided
magnets to transfer the blade onto the cutterhead.
Position the blade so it sits securely on the two pins.
• Use the 2 provided magnets to transfer the gib onto the
blade. Position the gib so the 6 holes are aligned with
the holes on the cutterhead.
• Tighten and secure with 6 bolts.
• To access the other blade assembly, gently pull and
hold the latch on the side of cutterhead to release it.
Once the cutterhead rotates, release the latch.
• Without touching the blades, carefully turn the
cutterhead until it stops the self-engaging latch.
• Repeat the same procedure to check and replace the
other blade.
• Replace the blade cover and secure with the two thumb
screws.
INSPECT AND REPLACE THE MOTOR
BRUSHES
• Turn the switch to the “OFF” position and disconnect the
planer machine from the power source.
• Inspect the motor brushes after every 100 hours of use.

• To inspect motor brushes, unscrew brush caps on the
sides of motor. There are two caps, one on each side of
