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 three installation bolts evenly
and alternately with the socket wrench.
For tool with mini planer blades (Fig. 1, 5 &6)
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 adjust
plate to the set plate with the pan head screws
and set the mini planer blade on the gauge base
so that the cutting edge of the blade is perfectly
flush with the inside flank of the gauge plate.
3. Set the adjust 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 adjust 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 adjust plate is flush with the back side of
the gauge base. Check this alignment carefully
to ensure uniform cutting.
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.

(B) Rear base (Stationary shoe)

5. Slip the heel of the adjust plate into the groove of
the drum.
6. Set the drum cover over the adjust 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 hand rotate the
drum to check clearances between the blade
ends and the tool body.
9. Check the three hex flange head bolts for final
tightness.
10. Repeat procedures 1 – 9 for other blade.
For shiplapping (Fig. 7)
The blade edge should be made to protrude outside
slightly (0.3 mm – 0.6 mm). Otherwise, nicks and gen-
erally poor shiplapping results.
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.
