17. USE RECOMMENDED ACCESSORIES. Consult the owner's manual for
recommended accessories. The use of improper accessories may cause risk
of injury to persons.
18. NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or
if the cutting tool is accidentally contacted.
19. CHECK DAMAGED PARTS. Before further use of the tool, a guard or other
part that is damaged should be carefully checked to determine that
it will
operate properly and perform its intended function - check for alignment
of moving parts, binding of moving parts, breakage of parts, mounting, and
any other conditionsthat may affect itsoperation. A guard or other part that
is damaged should be properly repaired or replaced.
20. DIRECTION OF FEED. Feed work into a blade or cutter against the direction
of rotation of the blade or cutter only.
21. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don't
leave tool
until it comes to a complete stop.
22. When servicing use only identical replacement parts.
23. POLARIZEDPLUGS. To reducethe risk of electric shock, this equipment has
a polarized plug (one blade is wider than
the other). This plug will fit in a
polarizedoutlet only one way. Ifthe plug does notfit fully in the outlet, reverse
the plug. If it still does not fit, contact a qualified electrician to install the
proper outlet. Do not change the plug in any way.

Dimensional adjustment
Width of workpiece being cut
Lower the main frame by turning the crank
handle counterclockwise until the indicator
plate points to the scale graduation indicat-
ing the desiredfinished dimension. One full
turn of the crank handle moves the main
frame
2 mm (3/32”) up or down. The scale
has inch graduations on its right side and
metric graduations on its left side.
Maximumdepth of cut
Main frame
150
mm (5-7/8”) - 240 mm (9-1/2“)
240
mm (9-1/2”) - 304 mm (12”)
Adjusting depth of cut
The maximum depth of cut differs depending upon the width of workpiece being cut.
Refer to the table below. When you need to remove more than the amount specified in
the table, set the depth of cut shallower than the amount and maketwo or more passes.
1.5 mm (1/16”)
1 .O mm (3/64“)
To adjust the depth of cut, proceed as fol-
lows.
Insert the workpiece flat on the table top.
Lower the main frame by turning the crank
handle counterclockwise. The depth gauge
will rise and the amount of gauge rise indi-
cates the depth of cut.
CAUTION:
*Always lower the main frame when aligning the indicator plate with the graduation in-
dicating the desired finished dimension.
If you raise the main frame into the desired fin-
ished dimension, additional play in the screw may result. This may cause an undesired
finished dimension.
*Always place the workpiece flat on the table top when predeterming the depth of cut.
Otherwise, the predetermineddepth of cut will differ from actual depth of cut.

Depth adjusting gauge
Use the depth adjusting gauge when you need to predetermine the depth of cut more
accurately.
To do so, proceedas follows.
*First, plane the workpiece
at the predetermined depth of cut. Measure the thickness of

Operation
CAUTION:
Two or more pieces of narrow but similar thickness stock can be passed through the
planer side by side. However, allow some spacing between the stock to permit the feed
rollers to grip the thinnest piece. Otherwise,
a slightly thinner piece could be kicked back
by the cutterhead

Place the workpiece flat on the table top.
Determine the depth of cut as described
before. Switch on the tool and wait until
the blades attain
full speed. The workpiece
should not be in contact with the feed roller
when you turn the tool on. Then insert the
workpiece flush with the table top.
When cutting
a long or heavy workpiece,
lift up its end slightly
at the start and the
end of the cut to avoid gouging or sniping
at the extreme ends of the workpiece.
