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/vibra-
tion will result, causing poor planing action and, eventu-
ally, 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 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. Below are some
examples of proper and improper settings.
(A) Front base (Movable shoe)
(B) Rear base (Stationary shoe)

Adjusting the depth of cut (Fig. 5)
Depth of cut may be adjusted by simply turning the knob
on the front of the tool.
Switch action
CAUTION:
Before plugging in the tool, always check to see that the
switch trigger actuates properly and returns to the "OFF"
position when released.
For tool without lock button and lock-off button
(Fig. 6)
To start the tool, simply pull the trigger. Release the trig-
ger to stop.
CAUTION:
Tighten the blade installation bolts carefully when attach-
ing the blades to the tool. A loose installation bolt can be
dangerous. Always check to see they are tightened
securely.

For tool with lock button (Fig. 7)
To start the tool, simply pull the trigger. Release the trig-
ger to stop. For continuous operation, pull the trigger and
then push in the lock button. To stop the tool from the
locked position, pull the trigger fully, then release it.
For tool with lock-off button (Fig. 7)
To prevent the trigger from being accidentally pulled, a
lock-off button is provided. To start the tool, press the
lock-off button and pull the trigger. Release the trigger to
stop.
Although this side view cannot show it,
the edges of the blades run perfectly par-
allel 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.
