To remove the blades on the drum, unscrew the five
installation bolts with the hex 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 /vibra-
tion will result, causing poor planing action and eventu-
ally tool breakdown.
There are two adjusting screws for each blade. When
installing the blade, the notch in the blade should fit over
the head of the adjusting screw. Then fit on the drum
cover and secure the five bolts only finger-tight.
Turn the drum until the blade edge is right in the middle
between the front and rear bases.
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. 4)
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. 5)
To start the tool, simply pull the trigger. Release the trig-
ger to stop.
For tool with lock button (Fig. 6)
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.
Place the triangular rule flat on the rear base and run it
out over and across the blade edge. Turn the two adjust-
ing screws to adjust the blade protrusion. The blade set-
ting should be made so that the protrusion will be uniform
all the way across. Thus the triangular rule should be
flush with the entire width of the blade edge. After adjust-
ing both blades, tighten the five installation bolts evenly
and alternately with the hex wrench.
After tightening the bolts, secure the adjusting screws
fully.
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-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.
Planing operation (Fig. 8)
First, rest the tool front base flat upon the workpiece sur-
face without the blades making any contact. Switch on
and wait until the blades attain full speed. Then move the
tool gently forward. Apply pressure on the front of tool at
the start of planing, and at the back at the end of planing.
Planing will be easier if you incline the workpiece in sta-
tionary fashion, so that you can plane somewhat down-
hill.
The speed and depth of cut determine the kind of finish.
The power planer keeps cutting at a speed that will not
result in jamming by chips. For rough cutting, the depth of
cut can be increased, while for a good finish you should
reduce the depth of cut and advance the tool more
slowly.
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.
