CAUTION:
Tighten the blade installation bolts carefully when
•

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

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
oscillation/vibration will result, causing poor planing
action and, eventually, tool breakdown.
Fig.5
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.

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.
