Operating Instructions
TRIGGER "ON/OFF" SWITCH
Hold the tool with both
hands while starting the
tool, since torque from the motor can
cause the tool to twist.
To turn tool "ON", depress the "Lock-OFF"
button and squeeze the trigger switch.  To
turn the tool "OFF", release the trigger
switch which is spring loaded and will return
to "OFF" position automatically.
To increase switch life, do not turn switch on
and off while tool and drum are held against
a workpiece.
BRAKE
When the trigger is released it activates the
electrical brake to stop the blade quickly. This
feature is especially useful when making
repetitive cuts.
PLANING ACTION
Check that the workpiece is held in place
securely on your work surface, and standing
comfortably, hold the planer firmly with both
hands.  With the planer fully adjusted, place
the front shoe on the workpiece, (be certain
that the cutter drum is not in contact with
the work) and start the planer as described
earlier.  With pressure on the front shoe, and
the fence against the side of the work (to
control the width or angle,) feed the planer
steadily until the rear shoe fully engages the
workpiece. Now gradually transfer pressure
to the rear shoe, and continue planing to the
end of the cut.  Feed the planer at a uniform
and reasonable rate, which does not put
excessive strain on the motor or blades, (do
not pull the planer back over the surface
already cut.)  Use progressive cuts until you
are near the desired depth, and then re-
adjust to a light cut for the final pass to
obtain a good surface finish.
The motor may stall if
improperly used or
overloaded. Reduce the pressure (feed
rate) or depth of cut to prevent possible
damage to the tool if the motor labors.

CAUTION
ADJUSTING DEPTH OF CUT
Proper cutting depth should be determined
according to the hardness, gumminess or
moisture content of the material being cut,
as well as the feed rate, and is largely a
matter of experience.  Start with a light cut
and increase the depth setting if the plane
moves freely through the workpiece with no
excessive load on the motor.  Do not change
depth of cut while planing.
The cutting depth is determined by the
difference in height between the adjustable
front shoe, and the fixed rear shoe of the
planer.  As the front shoe is adjusted, it
retracts and exposes the blade, which can
then remove the desired amount from the
workpiece.  The cutting depth is graduated
from 0 to 1/16 of an inch, and the "0"
indicates the blade is fully retracted. 
Adjusting depth of cut:  Rotate depth
adjustment knob until the indicator engages
the detent which indicates the desired
cutting depth on the depth scale (Fig. 1).
The planer may be set to cut any depth from
0 to 1/16 of an inch.
STANDARD PARALLEL WIDTH
GUIDE FENCE
The width guide fence can be used to cut
various desired widths (Fig. 1).
Installing the guide fence:  Place the wing
knob through the appropriate hole in the
guide bracket and screw into the housing.
Securely tighten wing knob.
Setting the cutting width:  Loosen wing knob
and slide the fence along the guide bracket
to the desired position.  Securely tighten
wing knob.  Be certain that the flat washer
(supplied) is fitted between the bottom of the
guide fence and wing knob or the guide
fence is likely to slip.
DELUXE ANGLE FENCE
The optional deluxe angle fence (Fig. 6) can
be used to cut various desired widths, with
the additional capability of guiding the
