so that the foot comes out of the rear base. This pre-
vents the planer blades to be damaged.
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 planer blades to
the tool. A loose installation bolt can be dangerous.
Always check to see they are tightened securely.
CAUTION:
Handle the planer blades very
carefully. Use gloves or rags to protect your fin-
gers or hands when removing or installing the
blades.
CAUTION:
Use only the Makita wrench
provided to remove or install the planer blades.
Failure to do so may result in overtightening or insuf-
ficient tightening of the installation bolts. This could
cause an injury.
For tool with conventional planer
blades
To remove the planer blades on the drum, unscrew the
installation bolts with the hex wrench. The drum cover
comes off together with the blades.

To install the planer blades, do the following procedure.
1. Clean out all chips or foreign matter adhering to
the drum and planer blades.
2.
Choose planer blades of the same dimensions
and weight. Otherwise drum oscillation/vibration will
result, causing poor planing action and, eventually, tool
breakdown.
3. Use the blade gauge to set the planer blades cor-
rectly. Put the planer blade on the blade gauge. Apply
the cutting edge of the blade on the inside flank of the
blade gauge.

Press the adjusting plate so that its heel is flush with the
back side of blade gauge. Tighten two screws on the
adjusting plate.
5. Slip the heel of the adjusting plate into the drum
groove, then fit the drum cover on it.
6. Tighten all the installation bolts evenly and alter-
nately with the hex wrench.
7. Repeat the procedure above for the other blade.
For tool with mini planer blades
To replace the mini planer blades, do the following
procedure.
1. Carefully clean the drum surfaces and the drum
cover.
2. Unscrew the three installation bolts with the hex
wrench. Remove the drum cover, adjusting plate, set
plate and the mini planer blade.

side of the blade gauge and tighten the screws. Check
the alignments carefully to ensure uniform cutting.
6. Slip the heel of the adjusting plate into the groove
of the drum.

Put the drum cover on the set plate and loosely fit
them onto the drum with the three bolts. Slip the mini
planer blade into the space between the drum and set

between the blade ends and the tool body.
