1. USE ONLY FOR WOOD. This
machine is not designed to process
any material other than wood.
2. ALWAYS KEEP FINGERS AND
HANDS AWAY FROM ROTATING
CUTTERHEAD. Never attempt to
clear chips away from the base of
the chip chute when the machine is
running. Stop the machine, unplug
it, then clear away the debris.
3. NEVER OPERATE WITH DULL
OR DAMAGED BLADES. Check
blades frequently for sharpness or
damage. Damaged or dull blades
put excessive strain on the machine
and can cause loss of control of the
unit.
4. ENSURE PLANER IS PROPERLY
ADJUSTED BEFORE STARTING.
Always use a test piece to check the
adjustment and operation before
starting on the actual workpiece.
Safety Instructions For Portable Planers
5. DO NOT REMOVE EXCESSIVE
AMOUNTS OF WOOD IN A SINGLE
PASS. Better results can be
achieved by taking multiple passes
with a small amount of material
removal in each pass.
6. INSPECT STOCK THOROUGHLY
BEFORE PLANING. Look stock
over for any grit, sand, nails, staples
or other foreign materials before per-
forming planing operations. Foreign
materials can damage the blade and
can throw off debris which may
cause injury.
7. MAKE SURE WORKPIECE IS
SECURELY CLAMPED OR OTH-
ERWISE HELD IN PLACE. Also
make sure the clamps will not
obstruct the movement of the Planer
as it progresses through the cut.
Hitting an unexpected obstruction
can cause potential loss of control of
the machine.

The Planer comes with the blades already
installed. Check the blades before the first
use to make sure they are set properly.
To Check Blade Height Setting:
1. Lay a straightedge across the
Rear Foot and the Cutterhead. Do
not position the straightedge so it
contacts the Front Foot. See
Figure 2.
BLADE ADJUSTMENT & REMOVAL
Figure 2. Checking Blade height.
2. Rotate the Cutterhead manually
with the exposed portion of the belt
(right next to the Cutterhead). The
tip of the blade at its highest point
should just barely touch the
straightedge. Move the straight-
edge back and forth across the
width of the blade to make sure

the amount of contact is the same
all the way across.
3. If there is too much contact, or
none at all, at any point across the
blade, then the blade needs to be
reset. Refer to Blade Installation
Section.
4. Repeat procedure for the other
Blade.
To Remove the Blade Assemblies:
1. Using the belt pulley, rotate the
Cutterhead so that one of the two
Blade Holders is positioned in the
opening in the base.
2. Use the supplied T-handle wrench
to remove the three hex head bolts
holding the Blade Assemblies to
the Cutterhead. Hold the
Cutterhead in position with the Belt
Pulley. See Figure 3.
3. Lift the Blade Holder and Blade
Assembly off, being careful to not
come in contact with the sharp
edge of the blade.
4. Repeat procedure for the other
Blade.
Turn the switch off and unplug the
Planer from power before attempting
blade removal or any adjustments.
Serious injury may occur if the unit
should be accidentally started while
checking or removing the blades.

BLADE INSTALLATION
The Blade must be mounted to the Back
Plate using the Blade Setting Jig. Using
this jig controls how far the blade extends
from the Cutterhead once it is installed.
1. Place the Blade onto the Setting
Jig.
2. Lay the Back Plate onto the top of
the Blade, pushing it up firmly
against the edge of the Jig. See
Figure 4.
Turn the switch off and unplug the
Planer from power before attempting
blade installation or any adjustments.
Serious injury may occur if the unit
should be accidentally started while
installing the blade.
Never operate the Planer with only
one blade installed. This will cause
an imbalance of the rotating cutter-
head and may allow the Planer to go
out of control, possibly causing
injury.

3. Install two Phillips®head screws
with washer and lockwasher
through the slots on the Back
Plate into the Blade. Tighten
securely.
4. Set the Blade/Back Plate
Assembly onto the Cutterhead.
Make sure the bottom edge of the
Back Plate is positioned into the
slot on the Cutterhead. See
Figure 5.
5. Set the Blade Holder over the
Blade Assembly so the notches in
the side of the Holder engage the
rear edge of the blade. Install three
hex head bolts and washers, and
tighten with the supplied T-handle
wrench.
6. Repeat the procedure for the other
blade.
Make certain edge of back plate
engages in slot in cutterhead

The Blade must be completely removed
from the Planer and from the Back Plate in
order for it to be safely sharpened. Follow
the preceding instructions for Blade
Removal.
For the best results, have planer blades
sharpened by a professional sharpening
service which has the grinding and mea-
surement equipment to assure that the
blade cutting geometry is maintained at
optimum levels. It is a procedure which
requires special equipment and precision,
otherwise, a set of blades can be easily
ruined. Knives should always be ground as
a set so that an equal amount of material is
removed which will maintain the balance of
the cutterhead.
The blades can be tuned up between
major sharpenings using the Sharpening
Jig supplied. Remove both Blades com-
pletely from the Planer.
To Sharpen Blades:
1. Separate the Blade from the Back
Plate by removing two Phillips®
head screws.
2. Mount the two Blades onto the
Sharpening Jig as shown in
Figure 6.
BLADE SHARPENING
Planer blades are dangerously sharp.
Use extreme caution when inspecting,
removing, sharpening, or replacing
blades into the cutterhead. Substantial
risk of laceration injury exists!
Fig 6. Blades in Sharpening Jig.
3. The bevel edge of the blades will
extend beyond the sloped edge of
the Jig. The blades can be sharp-
ened by sweeping a fine metal file
along the two edges, using the
existing bevel angle as a guide. Or
the entire Jig can be turned face
down on a sharpening stone and
swept across the surface of the
stone.
4. Remove the Blades from the Jig
and reinstall into the Planer.
Blade sharpness is one of the most impor-
tant factors in getting good results with the
planer. Take care to ensure that the work-
piece being planed is free from grit, dirt, or
nails or other embedded metals such as
staples. These can nick or chip the knives
and can require a complete regrinding.

Setting Cutting Depth
Lay a straightedge across the Rear Foot
and extend it across the Front Foot. Rotate
the cutterhead so neither of the blades are
touching the straightedge. Turn the Depth
Adjustment Knob until the Front and Rear
plates are at the same height (the straight-
edge will contact both feet evenly). This is
a “0” depth of cut. Note the position of the
“0” point on the knob scale. Three-quarters
of a full rotation of the knob is equivalent to
a 1⁄32" depth of cut, the maximum depth of
cut recommended. Generally the best
results will be achieved with several
successive passes rather than trying to remove
the maximum amount of material in one pass.
OPERATIONS
Planing
The most common operation is to plane
the edge of a board to get a straight,
square edge. A Portable Planer is also
useful when an uneven edge is required,
such as when fitting a countertop to a wall.
The Planer can be used to cut right down
to a scribe line by taking selective cuts.
This Planer can also be used for face plan-
ing, that is, to clean up the rough surface of
a board. This is most easily accomplished
on boards which are less than 33⁄16" wide
where the planing can be done in a single
pass. Success in face planing will be best
when very light passes are made.
To Perform Planing Operations:
1. Secure the workpiece firmly with
clamps so it will not move during
the planing process.
2. Set the desired depth of cut.
3. Turn the Planer on by pulling the
ON/OFF trigger. Allow the cutter-
head to achieve full speed before
engaging the workpiece.
4. Once the cutting begins, push the
Planer firmly across the workpiece
at the same rate of speed. Do not
stop the Planer’s progress across
the piece during the pass. Do not
apply downward pressure, use the
handle to apply force to push the
Planer along.
5. Check the edge for straightness
and squareness, or for the desired
profile, as successive passes are
made.
Operating this equipment has the
potential to propel debris into the air
which can cause eye injury. Always
wear safety glasses or goggles when
operating equipment. Be certain the
safety glasses you wear meet the
appropriate standards of the
American National Standards
Institute (ANSI).
