ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Removing or installing planer blades
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 tight-
ened securely.
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)

• Handle the blades very carefully. Use gloves or rags to
protect your fingers or hands when removing or install-
ing the blades.
• Use only the Makita wrench provided to remove or
install the blades. Failure to do so may result in over-
tightening or insufficient tightening of the installation
bolts. This could cause an injury.
To remove the blades on the drum, unscrew the installa-
tion 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/vibra-
tion will result, causing poor planing action and, eventu-
ally, 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.

Although this side view cannot show it,
(B)
the edges of the blades run perfectly
parallel to the rear base surface.
Cause: One or both blades fails to
have edge parallel to rear
base line.
Cause: One or both blade edges fails
to protrude enough in relation
(B)
to rear base line.
Cause: One or both blade edges
(B)
protrudes too far in relation to
rear base line.
