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.
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 all the installation bolts evenly and alternately
with the socket wrench.
For tool with mini planer blades
1. Remove the existing blade, if the tool has been in
use, carefully clean the drum surfaces and the
drum cover. 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.

2. To install the blades, loosely attach the adjusting
plate to the set plate with the pan head screws and
set the mini planer blade on the gauge base so
drum
that the cutting edge of the blade is perfectly flush
with the inside flank of the gauge plate.
3. Set the adjusting plate/set plate on the gauge base
so that the planer blade locating lugs on the set
plate rest in the mini planer blade groove, then
press in the heel of the adjusting plate flush with
the back side of the gauge base and tighten the
pan head screws.
4. It is important that the blade sits flush with the
inside flank of the gauge plate, the planer blade
locating lugs sit in the blade groove and the heel of
the adjusting plate is flush with the back side of the
gauge base. Check this alignment carefully to
ensure uniform cutting.
5. Slip the heel of the adjusting plate into the groove
of the drum.

6. Set the drum cover over the adjusting plate/set
plate and screw in the three hex flange head bolts
so that a gap exists between the drum and the set
plate to slide the mini planer blade into position.
The blade will be positioned by the planer blade
locating lugs on the set plate.
7. The blade's lengthwise adjustment will need to be
manually positioned so that the blade ends are
clear and equidistant from the housing on one side
and the metal bracket on the other.
8. Tighten the three hex flange head bolts (with the
socket wrench provided) and rotate the drum to
