GROUNDING INSTRUCTIONS
WARNING! This machine MUST BE GROUNDED while in use to protect the operator from
electric shock. In the event of a malfunction or breakdown, GROUNDING provides the path
of least resistance for electric current and reduces the risk of electric shock. The plug MUST
be plugged into a matching electrical receptacle that is properly installed and grounded in
accordance with ALL local codes and ordinances.
If a plug is provided with your machine DO NOT modify the plug. If it will not fit your electrical
receptacle, have a qualified electrician install the proper connections to meet all electrical
codes local and state. ALL connections must also adhere to NEC and OSHA mandates.
WARNING! IMPROPER ELECTRICAL CONNECTION of the equipment-grounding conductor
can result in risk of electric shock. The conductor with the green insulation (with or without yellow
stripes) is the equipment-grounding conductor. DO NOT connect the equipment-grounding conductor
to a live terminal if repair or replacement of the electric cord or plug is necessary.
Check with a qualified electrician or service personnel if you do not completely understand
the grounding instructions, or if you are not sure the tool is properly grounded.
WARNING! Electrocution or fire could result if this machine is not grounded properly or if the
electrical configuration does not comply with local and state electrical codes.
MAKE CERTAIN the machine is disconnected from power source before starting any
electrical work.
MAKE SURE the circuit breaker does not exceed the rating of the plug and receptacle.
The motor supplied with your machine is a 230 volt, 50 hertz, single phase motor. Never
connect the green or ground wire to a live terminal. A machine with a 230 volt plug should only
be connected to an outlet having the same configuration as the plug.
WARNING! To reduce the risk of fire or electrical shock, use the proper gauge of extension
cord. When using an extension cord, be sure to use one heavy enough to carry the current
your machine will draw.
The smaller the gauge-number, the larger the diameter of the extension cord is. If in doubt of
the proper size of an extension cord, use a shorter and thicker cord. An undersized cord will
cause a drop in line voltage resulting in a loss of power and overheating.
USE ONLY a 3-wire extension cord that has a 3-prong grounding plug and a 3-
pole receptacle that accepts the machine’s plug.
9
CAUTION!
GROUNDING INSTRUCTIONS
Make certain the extension cord is properly sized, and in good electrical condition. Always
replace a worn or damaged extension cord immediately or have it repaired by a qualified person
before using it.
Protect your extension cords from sharp objects, excessive heat, and damp or wet areas.

UNPACKING AND INVENTORY
Check shipping carton and machine for damage before unpacking. Carefully remove packaging
materials, parts and machine from shipping carton. Always check for and remove protective
shipping materials around motors and moving parts. Lay out all parts on a clean work surface.
Remove any protective materials and coatings from all of the parts and the planer. The
protective coatings can be removed by spraying WD-40 on them and wiping it off with a soft
cloth. This may need to be redone several times before all of the protective coatings are
removed completely.
After cleaning, apply a good quality paste wax to any unpainted surfaces including the infeed,
outfeed, and center tables. Make sure to buff out the wax before assembly.
Compare the items to inventory figures and verify that all items are accounted for. If at all
possible, retain shipping carton for warranty service if ever needed.
If any parts are missing, do not attempt to plug in the power cord and run the machine. The
machine should only be turned “ON” after all the parts have been obtained and installed correctly.

REPLACING KNIVES FOR JWP-12L
WARNING! MAKE CERTAIN THAT THE MACHINE IS DISCONNECTED FROM THE
POWER SOURCE BEFORE ANY ADJUSTMENTS ARE MADE.
WARNING! *** Be VERY CAREFUL when handling the knives or cutter tips as they are
EXTREMELY SHARP and can cause serious injury!!! ***
WARNING! NEVER GRASP THE CUTTERHEAD BY HAND!
The knives supplied with the planer have an edge on both sides of the blade enabling you to flip
the knives over when one edge becomes dull or pitted. To change:
1. The knife removal tool (A) is supplied with your planer and attached underneath the
outfeed table (B) with Velcro (C), you can storage the tool when it’s not in use. SEE FIG 6
on the following page.
2. Use the raise/lower handle to lower the cutterhead assembly down to 1”.
3. Remove the cutterhead guard (A) by removing the thumb screws (B). SEE FIG 7 on the
following page.
4. Rotate the cutterhead with the supplied Hex wrench (A). Rotate the cutterhead using the
wrench to the position where the sharp edge of the blade is not visible from your sight
angle. SEE FIG 8 on the following page.
5. Using the supplied torx wrench (B), unscrew the six screws (C) just enough so that the
locking bar (D) separates from the knife (E), allowing the knife to be removed. Do not
completely remove the screws. Insert the magnetic knife removal tool (F) underneath the
center of the locking bar. SEE FIG 8 & 9 on the following page.
6. Lift the tool up until the knife separates from the pins and remove the knife.
7. Rotate the knife 180 degrees so that the edge of the knife that was facing you is now facing
away from you and reinsert the knife. If you have already used both edges of the knife,
replace the knife at this time.
8. Place the magnetic knife removal tool on top of the knife. Make sure that the tool is
centered on the knife.
9. Place the knife on the pins in the cutterhead and remove the knife removal tool.
10. Retighten the six screws that were loosened in step 5 above.
11. Repeat this process for the remaining knife.
NOTE: When placing the knives on the pins, you will notice that there is some slight side to side
movement available in the knife. This is normal as it allows for repositioning of the knives in case
one of the knives gets a nick in it.

OPERATIONS
NOTE: This operations section was designed to give instructions on the basic operations of
this planer. However, it is in no way comprehensive of every planer operation. It is strongly
recommended that you read books, trade magazines, or get formal training to maximize the
potential of your planer while minimizing the risks.
NOTE: This planer is designed to process wood ONLY.
WARNING! Make sure the switch is in the "OFF" position before connecting cord into
socket. Do not touch the plug’s prongs when unplugging or plugging.
WARNING! In the case of a power outage (such as a breaker or fuse trip), always turn the
switch to the "OFF" position until the power is restored.
18
OPERATIONS
DEPTH-OF-CUT INDICATOR
The Depth-Of-Cut Indicator, located on the front of the machine, is a convenient way to
quickly determine how much material is being planed off in one pass.
1. With the machine OFF, insert your workpiece just under the cut scale (A). SEE FIG 11
2. Crank the raising / lowering handle until the button (B) comes in contact with the workpiece.
As you rotate the raise / lower handle, the needle on the depth of cut scale will move
showing how much material will be removed in that pass.
FIG. 11
GETTING PREPARED
It is always a good idea to use a piece of scrap wood for your first planing attempt. Also, before
each use of the planer, make it a habit of checking for loose fasteners, fittings or hardware. Turn
the planer ON and allow it to reach full speed. Pay close attention to any excessively loud
noises that may be coming from the planer or any excessive vibration. If either occurs, shut
down the planer immediately checking again for loose hardware. Go through the ASSEMBLY
and ADJUSTMENTS sections again if necessary.
BASIC OPERATION
WARNING! To avoid serious personal injury, NEVER stand directly in line with the front or rear
of the planer. If an object is thrown from the planer, it will travel in this direction.
1. Stand to either the left or right side of the planer.
2. Turn the switch to the ON position.
3. Lift the workpiece onto the infeed table by grabbing the edges of the board at the middle
of the length. NOTE: For longer pieces, be sure to use additional supports or stands.
3. Push slightly on the board to start feed and allow the feed rollers to pull the board through
the planer. Once the feed rollers start to pull the workpiece through, let go of the board and
allow the rollers to do their job. DO NOT push or pull on the workpiece once the rollers
have engaged.
4. Move to one side of the rear of the planer and receive the planed workpiece by grabbing the
edges of the wood like you did when feeding the workpiece in.
6. It normally takes several passes of varying depths to achieve a smooth finish, so repeat
this process as many times as necessary. Remember the less you take off in a pass, the
smoother the finish will be. Finish the surface by sanding.
19
OPERATIONS
THICKNESS PLANING
Thickness planing sizes the workpiece to a desired thickness, while at the same time creating a
smooth and level surface. The thickness of each cut will depend on the type of wood, width of
the workpiece, and condition of the lumber (i.e. dryness, grain composition, straightness, etc).
Always make thin test cuts on a scrap piece of wood prior to performing final cuts.
GENERAL TIPS AND GUIDELINES
1. Thickness planing always works best when at least one side of the workpiece has a flat
surface. If both sides of the workpiece are rough, feed one face of the board through
the planer until the entire surface is flat.
2. ALWAYS plane both sides of the workpiece to reach the desired thickness.
3. DO NOT plane workpieces less than 4.76mm thick, less than 19mm wide, or shorter than
178mm.
4. It is not recommended to continuously use the planer at its maximum depth of cut
(1.6mm) and at its full width (318mm) as this will shorten the life of the motor.
5. Light cuts create a smoother finish than heavier cuts.
6. If a smooth cut is not obtained, see TROUBLESHOOTING GUIDE on page 24.
AVOIDING SNIPE
Snipe, gouging or depression of the board at the ends, can occur when the board is not properly
supported. For workpieces longer than 1.2meter, greater care must be taken to reduce the
problem because the additional length of the workpiece translates into more unsupported weight
pulling down on the end of the board. This unsupported weight will work against keeping the
stock flat. Make sure to use supports or stands whenever long pieces are being planed to avoid
this problem. Since snipe occurs at the end of the boards, it is good practice to start with a
workpiece that is slightly longer than what you need so that you can simply cut off the ends if
necessary. Also see TROUBLESHOOTING for further information.
MAINTENANCE
WARNING! MAKE CERTAIN THAT THE MACHINE IS DISCONNECTED FROM THE
POWER SOURCE BEFORE PERFORMING ANY MAINTENANCE PROCEDURES
Your planer should provide you with a long time of service provided you take the time to
perform the following maintenance operations.
CLEANING
Sawdust buildup and other debris can cause the tool to plane incorrectly. Periodic cleaning
and waxing is needed for accurate, precision planing. Any moving parts should be cleaned
regularly with a penetrating oil and lubricated with a light coating of medium weight machine oil
