GENERAL SAFETY RULES
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.
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.
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 ignite the dust or fumes.
3. Keep children and bystanders away while operat-
ing a power tool. Distractions can cause you to lose
control.
ELECTRICAL SAFETY
1. Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any adapter
plugs with earthed (grounded) power tools. Unmodi-
fied plugs and matching outlets will reduce risk of electric shock.
2. Avoid body contact with earthed or grounded sur-
faces 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 condi-
tions. Water entering a power tool will increase the risk
of electric shock.
4. Do not abuse the cord. Never use the cord for carry-
ing, 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.
6. If operating a power tool in a damp location is
unavoidable, use a ground fault circuit interrupter
(GFCI) protected supply. Use of a GFCI reduces the risk
of electric shock.
PERSONAL SAFETY
1. Stay alert, watch what you are doing and use common 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 respiratory 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.
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.

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
users.
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 operation. 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 maintained 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 account the working conditions and the work to be performed. Use of the power tool for operations different
from those intended could result in a hazardous situation.
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

ELECTRICAL INFORMATION
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 electrician.
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.
3. Check with a licensed electrician or service personnel if you do not completely understand 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 (INSERT CR). Repair or replace a damaged or worn cord immediately.
Fig. 1
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
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.
AMPERAGE
25 ft. 50 ft. 100 ft. 150 ft.
1.6A 18 gauge 16 gauge 16 gauge 14 gauge
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.

WARNING! Do not plug in or turn on the tool until it is fully assembled according to the instructions. Read
through and become familiarized with the following procedures of handling and adjusting your tool. Failure to
follow the safety instructions may result in serious personal injury.
POSITIONING THE MACHINE
Place the machine on a stable, flat work surface. The machine has four rubber feet pre-installed to increase stability
and reduce vibration. Make sure there is sufficient open
space around the machine. Route the power cord so that
it will not make contact with the sharpener’s moving parts.
INSTALLING THE GRINDING WHEEL
A 220-grit grinding wheel is included with your sharpener,
and needs to be installed. Check the grinding wheel regularly to make sure that it is free or damage or cracks.
1. Remove the locking nut (Fig. 2 – 1) using a 19mm
wrench or socket. Slide the outer flange (Fig. 2 - 2) off the
spindle.
2. Install the grinding wheel (Fig. 2 - 3) onto the spindle
(Fig. 2 - 4), flush against the inner flange (Fig. 2 - 5).

5. Rotate the grinding wheel by hand a few turns to check
that the wheel is balanced and rotates smoothly.
INSTALLING THE WATER RESERVOIR
There are two mounting positions on the grinding wheel
side of the machine for installing the water reservoir. For
new wheels, use the lower mounting slots (Fig. 3 - 2). As
the wheel gets used, you will need to adjust the water reservoir to the upper slots (Fig. 3 - 3).
1. Install a new 10-inch grinding wheel.
2. Slide the notches on the water reservoir (Fig. 3 - 1) into
the two lower mounting slots (Fig. 3 - 2).

NOTE: Once the grinding wheel has been worn
down to roughly 8 inches in diameter, move the
water reservoir up to the upper mounting slots
(Fig. 3 - 3). This will allow the wheel to make
sufficient contact with the water in the reservoir.
11
ASSEMBLY & ADJUSTMENTS
INSTALLING THE WORK SUPPORT
The universal work support (Fig. 4 - 1) acts as both a work
rest and as an attachment arm for various jigs. The work
support can be installed either in the vertical (Fig. 4 - A) or
horizontal (Fig. 4 - B) position. The diameter of the work
support bar is 12 mm.
Position A - Against Wheel Rotation
Working against the rotation of the blade removes larger
amounts of material quickly. Use this method for shaping
blades or sharpening axes. The grinding wheel rotates to-
wards you.
To grind against the direction of the wheel rotation,
place the work support in the vertical mounts (Fig. 4 - A).
Position B - Along Wheel Rotation
Working along the rotation of the blade is preferable for
more precise jobs that require less material removal. For
fine sharpening on tools such as knives, scissors, or other
carving instruments, grind with the rotation of the wheel.
The grinding wheel rotates away from you.
Use the two-directional power switch to change the direction of the wheels’ rotation. Remove the workpiece from
the machine before changing rotation directions.

For grinding and honing along the direction of the wheel rotation, place the work support in the horizontal mounts
(Fig. 4 - B).
To mount the work support:
1. Select the suitable position for mounting the work support. Orient the work support so that the support arm is
extended over the wheel you’ll be working with.
2. Loosen the mounting locking knobs and slide the work support into the mounting bushings.
3. Adjust the height of the work support to fit your workpiece and operation. Refer to "Setting The Angle Using The
Angle Guide" on page 14 for setting up the work support for your blade’s bevel using the angle guide.
4. Use the fine adjustment nut (Fig. 4 - 2) on the threaded bar to make fine adjustments to the work support as
necessary. Make sure the support arm is completely parallel and level with the face of the wheel, whether it be in
the vertical or the horizontal position.
5. Secure the support in place by tightening both locking knobs.

ASSEMBLY & ADJUSTMENTS
SETTING UP THE HAND PLANE BLADE AND
CHISEL JIG
The hand plande blade and chisel jig included with your
sharpener is designed to assist in sharpening hand plane
blades (such as those on a bench plane; they are also
called "irons") and chisels.
1. To install the blade or chisel in the jig, loosen the clamping knobs on the jig (Fig. 5 - 1). Insert the body of the blade
or chisel into the clamp. Tighten the knobs, ensuring the
blade or chisel is securely mounted in the jig.
2. Follow the instructions on the next page for setting the
sharpening angle of the blade using the angle guide.
USING THE WORK SUPPORT ARM AS A WORK

ASSEMBLY & ADJUSTMENTS
SETTING THE ANGLE USING THE ANGLE GUIDE
Use the included angle guide (Fig. 8 - 2) to help set the correct angle for sharpening your tools.
NOTE: The included angle guide is only accurate for
relatively new wheels (10" in diameter). As your wheel
wears down, the angle guide will become less accurate.
1. Use the angle guide (Fig. 8 - 2) to measure the bevel
angle of your workpiece (Fig. 8 - 1). Place the blade into
each angle notch (Fig. 8 - arrows) to find the notch that
best fits the bevel of the blade.
2. Mount your workpiece in the appropriate sharpening jig.
3. Place the curved section of the angle guide against the
grinding wheel, with the edge of the jig associated with
your chosen angle facing up. For example, if your grinding
angle is 30 degrees, place the guide as shown in Fig. 9.
Adjust the position of the universal support arm and of the
jig so that one side of the workpiece edge lays flush against
the grinding wheel, and the other side lays flush against the
angle guide (Fig. 9).

FILLING THE WATER RESERVOIR
1. Fill up the container with clean, cold water up to the
"max water level" indicated on the inside of the reservoir
(Fig. 10).
2. Check the water level before each use. Be sure the wheel
is sufficiently wet before beginning any grinding operations. New wheels will tend to absorb water during their
first use. Make sure that enough water remains in the reservoir throughout the course of sharpening operations.
TIP: Putting a magnet inside of the reservoir can collect
metal filings as they fall into the water. This helps to
prevent build-up of metal filings on the grinding wheel.
CAUTION! Never leave the grinding wheel stored
in water, as this will damage one side of the wheel,
creating a lack of balance. Empty the water reservoir
after each operation.

PREPARING THE STROPPING WHEEL
The leather stropping wheel is pre-installed on the machine. Follow the instructions below to prepare the stropping
wheel before honing operations.
1. Turn the wheel by hand and apply a light machine oil evenly to the leather stropping wheel. Use enough to provide a thorough and even coat, but not so much as to dampen the wheel to the point of dripping oil. Turn the wheel
in both directions to ensure complete coverage.
2. Using a wooden spreader or other similarly purposed accessory (not included), apply the abrasive honing paste
to the stropping wheel, covering the face with a thin, even layer.
3. Make sure the locking knob on the side of the stropping wheel is securely tightened.
4. After the initial layer has been placed, turn the machine ON and continue to evenly distribute the paste with
the wooden spreader in light circular motions across the wheel. Once an even distribution has been reached, the
stropping wheel is ready to hone.

SHARPENING A BLADE (FIG. 11)
When sharpening knives and scissors, grind with the rotation of the wheel (that is, the grinding wheel rotates away
from you). When sharpening axes or chisels, grind against
the rotation of the wheel (that is, the grinding wheel rotates
toward you).
1. Stand to one side of the sharpener. Plug in and turn ON
the machine. Let the grinding wheel run for about one minute to warm up, making sure it is rotating evenly. Ensure
there is enough water in the reservoir.
2. Firmly grasp the blade to be sharpened with both hands.
Make sure it is properly supported. Feed the blade into the
grinding wheel with an even pressure.
3. Slide the blade back and forth along the support arm to
ensure even grinding on the blade and even wear on the
stone. Grind one side, then the other; repeat. If desired,
mark the bevel of the blade with a marker, then take a few
passes on the wheel to ensure that material is being removed evenly.
DANGER! FIRE HAZARD. Do not grind or polish
magnesium or magnesium alloys.
NOTE: Do not apply excessive pressure. Guide
the blade with light pressure. Let the grinding
wheel do the work.
CAUTION! Metal pieces become heated
quickly during grinding, so make sure to move the
workpiece back and forth to prevent overheating.

4. Switch on the machine and move the blade back and
forth evenly along the leather wheel. Do not apply excessive force to the workpiece; allow the honing wheel to do
the work.
Fig. 12
CAUTION! Always hone a blade WITH the
direction of the wheel rotation (so the wheel
rotates away from you). Never hone against the
wheel (so the wheel rotates toward you). The
work support must be installed in the horizontal
mounts. Attempting the hone the blade against
the direction of the wheel rotation, or with the
universal support arm in the vertical mounts, will
cause severe damage to the honing wheel.

MAINTENANCE
WARNING! To avoid accidents, turn OFF and unplug the tool from the electrical outlet before cleaning,
adjusting, or performing any maintenance 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.
ROUTINE INSPECTION
Before each use, inspect the general condition of the
tool. If any of these following conditions exist, do not
use until parts are replaced or the Sharpener is properly
repaired.
Check for:
• Loose hardware,
• Misalignment or binding of moving parts,
• Damaged cord/electrical wiring,
• Cracked or broken parts, and
• Any other condition that may affect its safe operation.
CLEANING & STORAGE
1. Keep the ventilation openings free from dust and debris to prevent the motor from overheating.
2. Use a vacuum or low-pressure compressed air to
remove dust and debris from the tool surfaces, motor
housing and work area.
3. Wipe the tool surfaces clean with a soft cloth or
brush. Make sure water does not get into the tool.
6. Cover the tool in order to protect it from dust and
moisture. It is preferable to store it in its original packaging with the instruction manual and all accessories.
LUBRICATION
Check the gearbox monthly and add a small amount of
white-lithium grease if necessary.
WATER RESERVOIR
Periodically empty out the water reservoir. Rinse it of
any metal filings and refill it with clean water to prevent buildup on the wheel itself. Your cleaning schedule
should depend on frequency of use.
Adjust the water reservoir mounting height to make
sure water levels are always sufficient to keep the wheel
wet during grinding operations.
DRESSING THE GRINDING WHEEL
Dress the grinding wheel periodically using dressing
tools (sold separately) to restore or adjust the wheel’s
abrasiveness. Follow the instructions that are included
with your dressing tools and accessories to properly
dress the grinding wheel.
CAUTION! Most plastics are susceptible to damage
from various types of commercial solvents. Do not use
any solvents or cleaning products that could damage
the plastic parts. Some of these include but are not
limited to: gasoline, carbon tetrachloride, chlorinated
cleaning solvents, and household detergents that contain ammonia.
4. Always empty the water reservoir and wait for the
grinding wheel to dry completely before storage. Do not
store the machine with a wet or damp grinding wheel.
5. Store the tool in a clean and dry place away from the
reach of children. Store in temperatures between 41° to
86°F.
Using a dressing stone with a coarse/smooth face:
• To remove larger amount of materials quickly, dress
the wheel for coarse grinding. Apply the coarse
face of the dressing stone to the grinding wheel to
roughen the wheel’s surface.
• For fine grinding, apply the smooth face of the
dressing stone to the grinding wheel to create a
finer surface.
