GENERAL SAFETY RULES
WORK AREA SAFETY
1. Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable liquids,
gases or dust. Power tools create sparks which may ig-
nite the dust or fumes.
3. Keep children and bystanders away while operating
a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
1. Power tool plugs must match the outlet. Never mod-
ify the plug in any way. Do not use any adapter plugs
with earthed (grounded) power tools. Unmodified plugs
and matching outlets will reduce risk of electric shock.
2. Avoid body contact with earthed or grounded surfac-
es such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body
is earthed or grounded.
3. Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of elec-
tric shock.
4. Do not abuse the cord. Never use the cord for car-
rying, pulling or unplugging the power tool. Keep cord
away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric
shock.
5. When operating a power tool outdoors, use an ex-
tension cord suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the risk of electric
shock.
6. If operating a power tool in a damp location is un-
avoidable, use a ground fault circuit interrupter (GFCI)
protected supply. Use of a GFCI reduces the risk of elec-
tric shock.
PERSONAL SAFETY
1. Stay alert, watch what you are doing and use com-
mon sense when operating a power tool. Do not use a
power tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of inatten-
tion while operating power tools may result in serious
personal injury.
2. Use personal protective equipment. Always wear
eye protection. Protective equipment such as a respira-
tory mask, non-skid safety shoes and hearing protection
used for appropriate conditions will reduce the risk of
personal injury.
3. Prevent unintentional starting. Ensure the switch is
in the off-position before connecting to power source
and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or
energizing power tools that have the switch on invites
accidents.
4. Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to a
rotating part of the power tool may result in personal
injury.
5. Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or jew-
elry. Keep your hair and clothing away from moving
parts. Loose clothes, jewelry or long hair can be caught
in moving parts.
Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool”
in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE SAFETY INSTRUCTIONS.
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may
result in electric shock, fire and/or serious injury.

GENERAL SAFETY RULES
7. If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection
can reduce dust-related hazards.
POWER TOOL USE AND CARE
1. Do not force the power tool. Use the correct power
tool for your application. The correct power tool will
do the job better and safer at the rate for which it was
designed.
2. Do not use the power tool if the switch does not turn
it on and off. Any power tool that cannot be controlled
with the switch is dangerous and must be repaired.
3. Disconnect the plug from the power source and/or
the battery pack from the power tool before making
any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
4. Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the power
tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained us-
ers.
5. Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool’s opera-
tion. If damaged, have the power tool repaired before
use. Many accidents are caused by poorly maintained
power tools.
6. Keep cutting tools sharp and clean. Properly main-
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits, etc.
in accordance with these instructions, taking into ac-
count the working conditions and the work to be per-
formed. Use of the power tool for operations different
from those intended could result in a hazardous situa-
tion.
8. Use clamps to secure your workpiece to a stable
surface. Holding a workpiece by hand or using your
body to support it may lead to loss of control.
9. KEEP GUARDS IN PLACE and in working order.
SERVICE
1. Have your power tool serviced by a qualified repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is main-
tained.
CALIFORNIA PROPOSITION 65 WARNING
Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities may contain

nia to cause cancer, birth defects, or other reproductive
harm. Wash hands after handling. Some examples of
these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement, and other
masonry products.
• Arsenic and chromium from chemically treated
lumber.
Your risk from these exposures varies depending on
how often you do this type of work. To reduce your ex-
posure to these chemicals, work in a well-ventilated area
with approved safety equipment such as dust masks
specially designed to filter out microscopic particles.

ELECTRICAL INFORMATION
3. Check with a licensed electrician or service personnel if you do not completely under-
stand the grounding instructions or whether the tool is properly grounded.
4. Use only three-wire extension cords that have three-pronged plugs and outlets that
accept the tool’s plug. Repair or replace a damaged or worn cord immediately.
CAUTION! In all cases, make certain the outlet in question is properly grounded. If you
are not sure, have a licensed electrician check the outlet.
GUIDELINES AND RECOMMENDATIONS FOR EXTENSION CORDS
GROUNDING INSTRUCTIONS
In the event of a malfunction or breakdown, grounding provides the path of least resistance for an electric current
and reduces the risk of electric shock. This tool is equipped with an electric cord that has 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.
1. Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a licensed electri-
cian.
2. Improper connection of the equipment grounding conductor can result in electric shock. The conductor with the
green insulation (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.
1. Examine extension cord before use. Make sure your extension cord is properly wired and in good condition.
Always replace a damaged extension cord or have it repaired by a qualified person before using it.
2. Do not abuse extension cord. Do not pull on cord to disconnect from receptacle; always disconnect by pulling on
plug. Disconnect the extension cord from the receptacle before disconnecting the product from the extension cord.
Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
3. Use a separate electrical circuit for your tool. This circuit must not be less than a 12-gauge wire and should be
protected with a 15A time-delayed fuse. Before connecting the motor to the power line, make sure the switch is in
the OFF position and the electric current is rated the same as the current stamped on the motor nameplate. Running
at a lower voltage will damage the motor.
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 line voltage resulting in loss of power and overheating. The table below shows
the correct size to be used according to cord length and ampere rating. When in doubt, use a heavier cord. The
smaller the gauge number, the heavier the cord.

four socket head bolts (Fig. 2 - 2)
2. Assemble the fence sliding bracket (Fig. 3 - 1) to the fence
(Fig. 3 - 2). Insert the two socket head bolts (Fig. 3 - 3) through
the top of the fence sliding bracket and screw the square nuts
(Fig. 3 - 4) onto the bolts but do not tighten.
3. Slide the square nuts into the grooves on the back of the
fence and position the fence sliding bracket to the middle of the
fence. Tighten the socket head screws (Fig. 3 - 3) once the slid-
ing fence bracket is correctly positioned.
NOTE: Use the fence cutout (Fig 4 - 1) to position the fence slid-
ing bracket in the center of the fence.
4. Place the upper fence assembly (Fig. 4 - 2) on top of the fence
support bracket. Insert the sliding handle (Fig. 4 - 3) through
the flat washer (Fig. 4 - 4), through the sliding bracket, and then
though the support bracket.
5. Hold the rectangular nut under the fence support bracket so
that it fits snugly into the groove with the flat side up. Thread
the sliding handle through the nut until it is tight. and the fence
is secured.
NOTE: The fence sliding handle and fence bevel handle are
spring-loaded and can be re-positioned as need be. Pull out on
the handle, re-position it, and let it spring back in place.
NOTE: The stop limits on the fence bracket have been set at the
factory, but should be checked with an angle gauge to measure
exactly 90° and 135° between the fence and the table top at each
stop limit, respectively. The stop limits can be modified by tight-
ening or loosening the set screws if the angles are not precise.
INSTALL THE DUST CHUTE
1. Remove the two M6x12 screws (Fig. 5 - 1) from the body of
the jointer and the two self tapping screws (Fig. 5 - 2) from the
feet of the jointer.
2. Position the dust port (Fig. 5 - 3) and reinstall all four screws.

ASSEMBLY & ADJUSTMENTS
ADJUST THE TABLE SUPPORTS
Your jointer is equipped with extendable table supports (Fig. 6 -
1). To extend the supports, loosen the two knobs (Fig. 6 - 2) on
each side of the support bar and reposition the support to the
desired position. Once the support is in the desired position, re-
tighten the knobs underneath the table.
ADJUST AND LEVEL THE TABLE
The infeed and outfeed table have been pre-set at the factory to
be level and in line with the blades. However, if shipping or use
has caused the table to shift out of level, adjust the tables with
the following steps. Make sure that the unit is unplugged from
any power supply before adjusting the table.
NOTE: This procedure involves close proximity to the helical
blades. To avoid cuts, wear cut-proof or cut-resistant gloves
when performing maintenance work. Remove the gloves before
operating the jointer.
1. Set the depth of cut scale (Fig. 7 - 1) to “0” to bring the infeed
table to its most up most position.
2. Rotate the cutterhead such that some of the blades are at
their highest point. The cutterhead can be safety rotated using
the included 4 mm hex wrench at the front end of the cutterhead
under the blade guard flange (Fig. 7 - 2).
3. Use a long metal straight edge to check the height of the
outfeed table. Place the straight edge over the outfeed table and
the cutterhead blades. Check that the blades barely touch the
straight edge at both the front and back of the cutterhead. You
will need to rotate the cutterhead to check both the front and
back alignment of the table.
4. If the blades do not touch the straight edge or drastically hit
the straight edge, the outfeed table will need to be adjusted.
a. Use the included 4mm hex wrench to loosen and remove
the bolts (Fig. 8 - 1) countersunk in the table. There are four
in the infeed table and four in the outfeed table. Remove the
washers as well to access the slotted screws (Fig. 8 - 2) un-
derneath.
Fig. 6

b. Use a flat head screwdriver to adjust the slotted screw. Turning the screw clockwise will lift the table up and
turning counterclockwise will lower the table. Adjustments to the screw should be minimal, with only a 1/20th
turn before rechecking the table’s position with the straight edge.
c. Once the table is level and at the correct height, reinstall the washer and bolt to secure the table.
5. Once the outfeed table is set at the correct height, follow the steps above to ensure that the infeed table is at the
correct height.

ASSEMBLY & ADJUSTMENTS
WARNING! Do not plug in or turn on the tool until it is fully assembled according to these instructions.
Failure to follow the safety instructions may result in serious personal injury.
ADJUST THE DEPTH OF CUT
The depth of cut is adjusted by the relative positioning of the
infeed table with respect to the cutterhead. The infeed table (Fig.
9 - 1) can be raised or lowered using the infeed adjustment knob
(Fig. 9 - 2). Turning the knob counterclockwise will raise the
infeed table, causing less wood to be removed from the work-
piece, as seen on the depth of cut scale (Fig. 9 - 3). Turning the
hand wheel clockwise will lower the infeed table, causing more
wood to be removed from the workpiece. Always make sure that
the front lock knob (Fig. 9 - 4) is loosened before changing the
depth of cut and tightened after the desired change has been
made so that the depth of cut does not differ between cuts. Do
not make jointing cuts deeper than 1/8 of an inch.
NOTE: For a smooth finish, it is recommended to do multiple passes at a lower depth. We recommend using a depth
of 1/32”. Always using a depth of 1/8” will shorten the lifespan of your jointer and give you a rougher finish.
BEVEL THE FENCE
NOTE: The fence can easily be set to 0° and 45° using the limit stops (Fig. 10 - 2) on the fence. However, it is always
advisable to check the angles with a piece of scrap wood before jointing your final workpiece. Adjust the set screws
that act as limit stops if they are not exact or have moved from shipping or use.
The fence can be positioned to joint the wood at any angle from 0° to 45°.
1. Before adjusting the fence’s angle, make sure that the unit is unplugged and the power switch is in the OFF posi-
tion.
2. Turn the fence bevel handle counterclockwise to loosen it. If you find it necessary to reposition the handle in order
to loosen it, pull it outwards, turn the handle to the new position, and release it.
3. Manually tilt the fence to desired angle; use an angle gauge block (not included) to see the current angle.
4. Once the desired angle has been achieved, tighten the bevel handle.
ADJUST AND LEVEL THE TABLE (CONT.)
6. When both the infeed and outfeed tables are aligned with the blades, lay the straightedge across the infeed and
outfeed tables to ensure that they are level. If the tables are not perfectly aligned, tune the outfeed table to the infeed
table using step 4 above to adjust the level of the table.

MOVE THE FENCE
1. Before adjusting the fence’s position, make sure that the unit is un-
plugged and the power switch is in the OFF position.
2. Loosen the fence sliding handle (Fig. 10 - 1).
3. Slide the fence to the desired position. The fence can be positioned
over the blade so that only the desired width of the blade is exposed.
Make sure the exposed width matches that of the workpiece.
4. Tighten the fence sliding handle so that the fence is secure.
AVOID DAMAGE TO BLADES

FEED A WORKPIECE
Feed rate refers to the rate at which wood is passed over the blades. An even feed rate produces a uniform finish.
1. Hold the work piece firmly down on the feed table and against the fence.
2. Feed the work piece at an even rate over the cutterhead. Any hesitation or stopping will cause a “step” to be cut
in the work piece. See Figs. 11 - 13 for different feeding methods.
3. As your trailing hand passes over the cutterhead, remove your leading hand and place behind your trailing hand
and repeat until the entire length of the workpiece has been cut. Always use a push block or push stick (Fig. 13 - 1),
but it is especially critical to help hold and feed the workpiece when jointing wood that is narrower than 3 inches or
thinner than 3 inches.
Directions continue on the next page.
Jointers are a precision woodworking machine and should be used on quality lumber only. Do not join dirty boards;
dirt and small stones are abrasive and will wear out the blades.
For proper operation, attach a dust collection system to the dust port, on the left of the jointer. Attaching a dust col-
lection system is very important when taking deeper cuts to prevent wood chips clogging the unit.
Remove nails and staples. Only use the jointer to cut wood. Avoid knots. Heavily cross-grained wood makes knots
hard. Knots can come loose and jam blades.
Assess the value of badly warped boards. You may be tempted to take a deep cut to square the boards quickly, when
a better approach is to use several passes with a shallower cut.

4. Cut with the grain whenever possible (Fig. 14). Do not feed against the end
grain (Fig. 15), otherwise the workpiece may split and shatter. If the nature of
the workpiece requires you to joint against the grain, take extremely light cuts
and feed slowly. When using long work pieces, use extra supports at both
ends of the jointer.
BEVEL AND CHAMFER
The fence on the jointer is adjustable from 0° to 45°. Adjust the fence to the
desired angle and tighten the bevel handle.
Beveling refers to cutting the entire edge of a board at an angle. Beveling may
require several passes due to the depth of the cut needed. See Fig. 16.
Chamfering refers to removing only the corner of the edge of a board. Nor-
mally a chamfer is made in one pass; so a 1/16-inch deep cut is made. See
Fig. 16.

A 2-1/2” (or 4” with the dust port adapter) dust collection hose can be at-
tached to the dust port underneath the outfeed table. The jointer will perform
properly at all depths of cuts up to 1/8” when using a dust collection system.
NOTE: Make sure the jointer and dust collection system are on separate elec-
trical circuits. This will prevent circuits from overloading.
1. Make sure the switch is in the OFF position and that the cord is unplugged
before attaching the vacuum hose.
2. Attach the dust collection hose to the dust port (Fig. 17 - 1).
3. Turn the dust collection system ON before starting the jointer. Periodically
replace and empty the bag in the collection system according to the manufac-
turer’s instructions.
ON/OFF SWITCH
The ON/OFF switch (Fig. 17 - 2) is located on the front of the jointer.
1. To turn the jointer ON, move the switch to the up position.
2. To turn the jointer OFF, move the switch to the down position.
3. Remove the yellow tab to engage the child-safety lock and prevent un-
wanted start-ups.

MAINTENANCE

ROUTINE INSPECTION
Before each use, inspect the general condition of the tool. If any of the following conditions exist, do not use until
parts are replaced or the jointer is properly repaired.
Check for:
• Loose hardware or improper mounting,
• Misalignment or binding of moving parts,
• Damaged cord/electrical wiring,
• Worn or damaged blades,
• Cracked or broken parts, and
• Any other condition that may affect its safe operation
CHECK FOR WORN BLADES
The condition of blades will affect the precision of the cuts. Observe the quality of the cut that the jointer produces
to check the condition of the blades. Dull blades will tear wood fibers and produce fuzzy surfaces. Raised grain will
occur when dull blades pound on wood that has varying density. Raised edges will also be produced where the
blades have been nicked. Blades on this jointer should always replaced as a matched set. Keeping a spare set of
blades on hand is recommended. Replacement blades (part no. BP510H) can be ordered from wenproducts.com.
NOTE: Blades are only sharp on two edges. Make sure that the edge facing the infeed table has a sharp cutting edge.
Refer to Fig. 18 for more detail.
WARNING! To avoid accidents, turn OFF and unplug the tool from the electrical outlet before cleaning, ad-
justing, or performing any maintenance or lubrication work.
WARNING! Any attempt to repair or replace electrical parts on this tool may be hazardous. Servicing of the
tool must be performed by a qualified technician. When servicing, use only identical WEN replacement parts.
Use of other parts may be hazardous or induce product failure.
WARNING! To avoid cuts, wear cut-proof or cut-resistant gloves when performing maintenance work. Re-
move the gloves before operating the jointer.

MAINTENANCE
WARNING! To avoid cuts, wear cut-proof or cut-resistant gloves when performing maintenance work on the
blades. Remove the gloves before operating the jointer.
REPLACING OR ROTATING BLADES
Your jointer is equipped with a helical cutting head consisting of either 20 or 24 blades, depending on the model.
Each blade is indexed with a small dot in the corner to denote the two sharp sides of the blade. Once a side of the
blade is dull or nicked, use the star head wrench to remove the retaining screw to rotate or replace the blade. The
blades are machined to be properly positioned once the retaining screw is tightened, but make sure that all dust and
debris is cleared away to help the blade be seated properly. Make sure that the unit is unplugged from the power
supply before changing any blades.
NOTE: To avoid cuts, wear cut-proof or cut-resistant gloves when performing maintenance work. Remove the
gloves before operating the jointer.
1. Insert the 4 mm hex wrench at the front of the cutterhead under the blade guard flange to hold the cutterhead
still while working with the blades.
2. Use the T25 star wrench to remove the retaining screw and the blade from the cutterhead.
3. While the blade is removed, check the cutterhead for any resin build up or dust that is stuck around the blade
location. Use a brush (such as an old toothbrush) and suitable solvents to clean the cutterhead so that the blade will
be seated properly.
4. Rotate or replace the blade to the desired position. Be sure to note the position of the small dot to ensure the blade
is being installed with a new sharp edge (Fig. 18).
5. Tighten the retaining screw back on the cutterhead to hold the blade in place. Do not overtighten the retaining
screw as this might damage the blade. Make sure that the screw is only tightened with a torque of about 50 inch-lbs.
CLEANING & STORAGE
1. After every operation, use a vacuum to remove dust and chips from the tool surfaces, motor housing and work
area. Keep the ventilation openings free from dust and debris to prevent the motor from overheating.
2. Wipe the tool surfaces clean with a soft cloth or brush. Make sure water does not get into the tool.
3. Lubricate the table bracket and locking knobs if they become difficult to use.
