Wear Eye Protection
1. KEEP GUARDS IN PLACE and in working order.
2. REMOVE ADJUSTING KEYS AND WRENCHES. Form the habit of checking to see that keys and
adjusting wrenches are removed from the tool before turning it on.
3. KEEP THE WORK AREA CLEAN. Cluttered areas and benches invite accidents.
4. DO NOT USE IN A DANGEROUS ENVIRONMENT. Don’t use power tools in damp or wet locations, or
expose them to rain. Keep work area well lighted.
5. KEEP CHILDREN AWAY. All visitors should be kept at safe distance from the work area.
6. MAKE THE WORKSHOP KID PROOF with padlocks, master switches, or by removing starter keys.
7. DON’T FORCE THE TOOL. It will do the job better and safer at the rate for which it was designed.
8. USE THE RIGHT TOOL. Don’t force a tool or attachment to do a job for which it was not designed.
9. USE THE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. When using
an extension cord, be sure to use one heavy enough to carry the current your product will draw. An
undersized cord will cause a drop in the line voltage resulting in loss of power and overheating. The table
below shows the correct size to use depending on the cord length and name plate ampere rating. If in
doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.
Volts Total Length of Cord in Feet
120V 25 50 100 150
240V 50 100 200 300
AWG
14 12 Not recommended
Table 1
10. WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other
jewelry which may get caught in moving parts. Nonslip footwear is recommended. Wear protective hair
covering to contain long hair.
11. ALWAYS USE SAFETY GLASSES. Also use face or dust masks if the cutting operation is dusty.
Everyday eyeglasses only have impact resistant lenses, they are NOT safety glasses.
12. SECURE WORK. Use clamps or a vise to hold the work when its practical. It’s safer than using your hand
and it frees both hands to operate the tool.
13. DON’T OVERREACH. Keep proper footing and balance at all times.
14. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest performance. Follow
instructions for lubricating and changing accessories.

5.0 Electrical connections
5.1 Grounding instructions
In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to
reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding
conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and
grounded in accordance with all local codes and ordinances.
Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified
electrician.
Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor
with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding
conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-
grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the grounding instructions
are not completely understood, or if in doubt as to whether the tool is properly grounded. Failure to
comply may cause serious or fatal injury.
Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the
tool's plug.
5.2 115 Volt operation
As received from the factory, your planer/molder is ready to run at 115 volt operation. This planer/molder, when
wired for 115 volt, is intended for use on a circuit that has an outlet and a plug that looks like the one illustrated
in Figure 1a. A temporary adapter, which looks like the adapter as illustrated in Figure 1b, may be used to
connect this plug to a two-pole receptacle, as shown in Figure 1b if a properly grounded outlet is not available.
The temporary adapter should only be used until a properly grounded outlet can be installed by a qualified
electrician. This adapter is not applicable in Canada. The green colored rigid ear, lug, or tab, extending from
the adapter, must be connected to a permanent ground such as a properly grounded outlet box, as shown in
Figure 1b.
Figure 1a Figure 1b
5.3 230 Volt operation
If 230V, single phase operation is desired, the following instructions must be followed:
1. Disconnect the machine from the power source.
2. This planer/molder is supplied with four motor leads that are connected for 115V operation, as shown in
Figure 2a. Reconnect these four motor leads for 230V operation, as shown in Figure 2b.
3. The 115V attachment plug, supplied with the planer/molder, must be replaced with a UL/CSA listed plug
suitable for 230V operation, similar to the one shown in Figure 3. Contact your local Authorized JET
Service Center or qualified electrician for proper procedures to install the plug. The planer/molder must
comply with all local and national codes after the 230 volt plug is installed.

7
4. The planer/molder with a 230 volt plug should only be connected to an outlet having the same
configuration as illustrated by the grounded outlet box in Figure 3. No adapter is available or should be
used with the 230 volt plug.
Important: In all cases (115 or 230 volts), make certain the receptacle in question is properly grounded.
If you are not sure, have a registered electrician check the receptacle.

thinner, paint thinner, or gasoline; these will
damage painted surfaces.
5. To prevent rust, apply a light coating of paste
wax to the table surface.
9.3 Assembly
1. Remove dust hood. Check gib screws on
cutterhead for tightness. Reinstall dust hood.
Note: Recheck after five minutes of operation.
Recheck again after every 2 hours of use.
2. Attach the handle to the post with a hex socket
cap screw.
3. Attach the top side of dust chute with three
M5x10 machine screws, and three M5
washers.
4. Attach lower section of dust chute with three
M6x8 machine screws, and three M6 washers.
5. Mount extension roller assembly to the middle
table with four M8x12 hex cap bolts, and four
M8 flat washers. The frame is adjustable using
these bolts.
6. Use a straight edge to make sure rollers are
level with middle table.
7. The first roller is adjustable by loosening the
hex cap bolts that hold the roller on the frame
supports.
8. Repeat steps 5-7 for opposite side roller
assembly.
Never run machine with dust
hood loose or removed. Failure to comply may
cause serious injury.
10.0 Adjustments: Planing
10.1 Depth of cut
Maximum depth of cut is 1/8”
up to 5-1/2” wide, and 1/16” on stock over 5-
1/2” wide. Trying to cut more in one pass will
cause stress on machine and could damage
cutterhead.
Thickness planing refers to the sizing of lumber to
a desired thickness while creating a level surface
parallel to the opposite side of the board.
The quality of thickness planing depends on the
operator’s judgment about the depth of cut. Depth
of cut depends upon the width, hardness,
dampness, grain direction, and grain structure of
the wood.
The maximum thickness of wood that can be
removed in one pass is 1/8” on wood up to 5-
1/2” wide and 1/16” on wood wider than 5-1/2”.
When planing hard wood, take light cuts or plane
wood in thin widths.
Make a test cut when working with a new type of
board or different kind of operation. Check the
accuracy of the test cut before working on the
finished product.
10.2 Adjusting depth of cut scale
Use caution when placing
hands near cutterhead. Knives are extremely
sharp. Failure to comply may cause serious
injury.
1. Take a test cut.
