CAUTION:

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 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 tool with standard planer blades
004886
To remove the blades on the drum, unscrew the installation 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 oscil-
lation/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 adjusting plate on the blade,
then simply press in the heel of the adjusting plate flush with the back side of
the gauge base and tighten two screws on the adjusting plate. Now slip the
002555
heel of the adjusting plate into the drum groove, then fit the drum cover on it.
1 Tighten all the installation bolts evenly and alternately with the socket wrench.
