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)
Correct setting

Adjusting the depth of cut (Fig. 12)
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. 13)
To start the tool, simply pull the trigger. Release the
trigger to stop.
For tool with lock button (Fig. 14)
To start the tool, simply pull the trigger. Release the
trigger to stop. For continuous operation, pull the trig-
ger 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. 15)
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.

show it, the edges of the blades run
perfectly parallel to the rear base

Planing operation (Fig. 16)
First, rest the tool front base flat upon the workpiece
surface 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 stationary fashion, so that
you can plane somewhat downhill. 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.
Shiplapping (Fig. 17, 18, 19 & 20)
To make a stepped cut as shown in Fig. 17, use the
edge fence.
Draw a cutting line on the workpiece. Insert the edge
fence into the hole in the front of the tool. Align the
blade edge with the cutting line.
Adjust the edge fence until it comes in contact with
the side of the workpiece, then secure it by tightening
the screw.
You may wish to add to the length of the fence by
attaching an extra piece of wood. Convenient holes
are provided in the fence for this purpose, and also
for attaching an extension guide (optional acces-
sory).
