CAUTION:
• Tighten the blade installation bolts carefully
when attaching the blades to the tool. A loose
installation bolt can be dangerous. Always
check to see they are tightened securely.
• Handle the blades very carefully. Use gloves
or rags to protect your fingers or hands when
removing or installing the blades.
• Use only the Makita wrench provided to remove
or install the blades. Failure to do so may result
in overtightening or insufficient tightening of the
installation bolts. This could cause an injury.
For the correct planer blade setting
Your planing surface will end up rough and uneven, unless the blade is set properly and securely. The blade must be
mounted so that the cutting edge is absolutely level, that is, parallel to the surface of the rear base.
Refer to some examples below for proper and improper settings.
(A) Front base (Movable shoe)
(B) Rear base (Stationary shoe)

To remove the blades on the drum, unscrew the instal-
lation bolts with the socket wrench. The drum cover
comes off together with the blades.
To install the blades, first clean out all chips or foreign
matter adhering to the drum or blades. Use blades of
the same dimensions and weight, or drum oscillation/
vibration will result, causing poor planing action and,
eventually, tool breakdown.

Place the blade on the gauge base so that the blade
edge is perfectly flush with the inside edge of the gauge
plate. Place the adjust plate on the blade, then simply
press in the heel of the adjust plate flush with the back
side of the gauge base and tighten two screws on the
adjust plate. Now slip the heel of the adjust plate into
the drum groove, then fit the drum cover on it. Tighten
the installation bolts evenly and alternately with the
socket wrench.

have edge parallel to rear
base line.
Cause: One or both blade edges
fails to protrude enough in
relation to rear base line.
Cause: One or both blade edges
protrudes too far in relation
to rear base line.
