To remove the blades on the drum, unscrew the three
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
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 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 heel of the adjusting plate
into the drum groove, then fit the drum cover on it.
Tighten the three 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.
Below are some examples of proper and improper
settings.

Although this side view cannot
show it, 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 to rear base line.
Cause: One or both blade edges
protrudes too far in relation
to rear base line.
