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 liq-
uids, 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 elec-
tric shock.
2. Avoid body contact with earthed or grounded sur-
faces such as pipes, radiators, ranges and refrigera-
tors. 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 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 elec-
tric 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
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 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 respi-
ratory mask, non-skid safety shoes and hearing protec-
tion 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
5
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
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 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
chemicals, including lead, known to the State of Califor-
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.
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.

SAW BLADE SAFETY
1. Always wear protective gloves when handling saw
blades.
2. Only use blades with correct size and type for both
your band saw and your workpiece.
• See the blade specifications on page 3.
• Make sure the blade is installed in the proper direc-
tion.
3. Never use damaged or deformed saw blades. Only
use sharp blades.
4. Install the saw blade in the correct orientation indi-
cated in the instructions.
5. Keep hands out of path of saw blade. Never use your
hands to remove scrap pieces.
6. Never reach around saw blade or reach in back of the
saw blade.
7. The use of accessories or attachments not recom-
mended by the manufacturer may result in a risk of per-
sonal injury.
PERSONAL SAFETY
1. Operate in a well ventilated area. Keep the floor area
around the band saw level and free of slippery sub-
stances or other tripping hazards.
2. Wear ANSI Z87.1-approved safety goggles to protect
your eyes from saw dust. Use hearing protection to pro-
tect yourself from hearing loss.
3. People with pacemakers should consult their
physician(s) before use. Electromagnetic fields in close
proximity to pacemakers could cause pacemaker inter-
ference or pacemaker failure.
4. Wear work gloves when handling saw blades. DO
NOT wear gloves, neckties, jewelry, or loose clothing
while operating the saw.
5. Saw dust is harmful to your health. Use NIOSH-ap-
proved dust masks or other respiratory protection dur-
ing operation and cleaning.
6. Always turn off and unplug the metal band saw be-
fore making any adjustments or repair tasks. Never ad-
just the metal band saw or the workpiece while the saw
is running.
PREPARING THE METAL BAND SAW
1. When transporting the metal band saw, never carry
the device by its guards or its accessories.
2. Examine the metal band saw for any damaged or
missing parts. Replace or repair damaged parts before
operation. Periodically check that all nuts, bolts, and
other fasteners are properly tightened.
3. To avoid injury from unexpected movement, secure
the machine to a bench before operating.
SECURE YOUR WORKPIECE
1. To avoid blade binding or loss of control, always se-
cure the workpiece to a stable platform, ensuring that
body exposure is minimized.
2. Ensure that work is correctly supported. Supports
must be placed under the workpiece on both sides,
close to the line of cut and near the edge of the work-
piece.
3. Use extra caution with very large, very small, or awk-
wardly-shaped workpieces. Small pieces should be se-
cured with clamps. Do not hold small pieces with your
hand.
4. Never hand-hold a workpiece that is too small to be
clamped, as it can be launched away and cause inju-
ry. Use proper support and guides to secure the small
workpiece.
SPECIFIC RULES FOR YOUR METAL BAND SAW
WARNING! Do not operate the power tool until you have read and understood the following instructions
and the warning labels.
6

DURING CUTTING OPERATIONS
1. Always stand to one side when operating the saw.
Never have any part of the body in line with the path of
the saw. Never hold a workpiece in your hand or across
your legs while cutting.
2. Ensure hands are away from the cutting area and
blade.
3. Feed work into the blade against the direction of rota-
tion of the blade only.
4. If you are interrupted when operating the saw, com-
plete the process and switch the saw off before looking
up.
5. Power tools must always be held by the insulated
gripping surfaces when performing an operation, en-
suring protection if the cutting tool makes contact with
its own cord or hidden wiring. Contact with a ‘live’ wire
will make exposed metal parts of the power tool ‘live’
and shock the operator if the insulated gripping surfac-
es are not used.
6. Do not use the metal band saw unless all guards are
in place. Do not operate with any guard disabled, dam-
aged, or removed. Moving guards must move freely and
close instantly.
7. Blade guide, supports, bearings, and blade tension
must be properly adjusted to avoid accidental blade
contact and to minimize blade breakage. To maximize
blade support, always adjust the upper blade guide and
blade guard so that it barely clears the workpiece.
8. Turn on the band saw and let it reach full speed, then
slowly slide the workpiece into the blade. This will help
produce safer and cleaner cuts.
9. Never cut more than one piece at a time. Do not stack
workpieces together. Do not attempt to cut material
thicker than specified on page 3 of this manual.
10. If a cut does not extend to the edge of the work-
piece, or if the blade binds in the cut, allow the blade
to come to a complete stop and lift the workpiece away
from the blade.
11. Turn off tool and wait for saw blade to stop before
moving workpiece or changing settings. Do not slow
or stop a blade with a piece of wood or by hand. Let
the blade come to rest naturally. Do not attempt to free
a jammed blade while the machine is still running and
connected to power.

GUIDELINES AND RECOMMENDATIONS FOR EXTENSION CORDS
When using an extension cord, be sure to use one heavy enough to carry the current
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.
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.

make an adjustment to the cutting angle:
1. Loosen the angle lock handle (Fig. 5 - 1).
2. Turn the swivel support (Fig. 5 - 2) until the mark on the support
matches the desired angle on the scale.
3. Tighten the miter locking handle.
NOTE: Your saw has 2 positive stops for quick adjustment. To adjust
the position of the positive stops, loosen the socket head cap screw
(Fig. 6 - 1) with a 5mm hex wrench, re-position the stop, and tighten
the screw.
STATIONARY BLADE GUIDE
When setting up your saw for the first time or after installing a new
blade, check to ensure that the stationary blade guide assembly is prop-
erly adjusted.
1. Using a hex wrench, loosen the 2 socket head cap screws (Fig. 6 - 2).
2. Adjust the position of the stationary blade guide assembly so that its
side lays flush with the body of the saw.
3. Tighten the screws.
SLIDING BLADE GUIDE
The blade guide must be adjusted before every cut on a workpiece.
Without proper adjustment, the resulting cut may be unclean or jagged.
1. Loosen the blade guide locking handle (Fig. 7 - 1).
2. Slide the blade guide to move it closer to the workpiece. Position the
guide bearings as close to the workpiece as possible without interfering
with the cut. Tighten the blade guide locking handle.
CUTTING SPEED
The cutting speed depends on the material being cut. Generally, use
a lower speed for ferrous metals or thicker workpieces, and a high-
er speed for non-ferrous metals or thinner workpieces. To adjust the
speed, turn the control knob (Fig. 8 - 1). The speed ranges from 125 to
260 FPM.
• For common steel, use a speed between 125 and 180 FPM (settings
1 to 3).
• For aluminum or alloy, use the maximum speed of 260 FPM (setting
6).
• For pipes, use a speed between 220 and 260 FPM (settings 4 to 6).

OPERATION
OPERATING THE METAL BAND SAW
1. Pull out the pin (Fig. 9 - 1) from the hole in the saw’s
body and tilt the saw to its upper position. Set the blade
stop to the desired position (Fig. 10 - 2).
NOTE: Never adjust the blade stop bolt so that the blade
interferes with any part of the saw. Always check to be sure
that the blade will not cut any part of the saw.
2. Use the vise to secure the workpiece in place (Fig. 10 -
1). Adjust the cutting speed to the desired rate.
3. Push the green button (Fig. 11 - 1) to turn on power to
the saw. The power indicator light (Fig. 11 - 2) will light up,
but the blade will not start running yet. Pull the run trigger
(Fig. 12 - 1) to start the blade running.
4. Once the saw blade has come to full speed, gradually
lower the saw body downwards until the blade comes into
light contact with the workpiece. Let the saw blade make a
small groove along the workpiece to help ensure a straight
cut (particularly with curved or round workpieces).
5. Once initial contact and a groove have been made, apply
a small amount of additional pressure to continue the cut.
Let the machine do the work.
NOTE: For optimal performance, cutting should only occur
for 40% of the overall run time. For example, for every 10
minutes the machine is running, only four of those minutes
should be under load in order to maximize the performance
of the machine.
WARNING! When cutting magnesium, if using
cutting oils, NEVER use water-soluble cutting oils
or emulsions (oil-water mix). The water will greatly
intensify any accidental magnesium chip fire and cause
danger.

MAINTENANCE
CHANGING THE SAW BLADE Fig. 13
WARNING! Turn off the machine and disconnect the power supply before conducting any maintenance
work or adjusting any settings.
Fig. 14
WARNING! Band saw blades are extremely sharp! Always wear
gloves when handling saw blades. Replace the band saw blade when
it becomes dull. A sharp blade gives the best cuts and helps extend
the life of your machine. Replacement blades (model no. 3975-056
and BB5650) can be purchased from wenproducts.com.
1. Remove blade cover by unscrewing the six screws shown in Fig. 13.
2. Relieve the blade tension by turning the blade tension adjustment
knob counterclockwise (Fig. 14 - 1).
3. Carefully remove the blade, first from between the guide bearings
and then from around the wheels.
4. Insert the new blade, first between the guide bearings and then
around the wheels.
NOTE: Install the blade so that the teeth point in the direction of the
saw’s rotation.
5. Turn the blade tension adjustment knob (Fig. 14 - 1) until the blade is
taut. The blade is properly tensioned when pressing lightly on the side
of the blade moves the blade about 1/8 in.
6. Replace the blade cover and install the six screws (Fig. 13).
7. Run the saw at no-load for 10 – 20 seconds to allow the blade to seat on the wheels.
8. Adjust the blade guide in preparation for the next cut.
GENERAL MACHINE CARE
1. Routinely check the condition of the power supply cords and replace them if they are broken, worn or if internal
wires are showing.
2. Use a brush to remove chips and other debris from the machine. Wipe off any cutting oil or other processing
residue from the blade, guide bearings, vise, and rest of the saw whenever necessary, and especially before storing
the saw. TIP: Apply a light coat of good-quality paste wax to the ways of the vise to protect it against damage and
rust, and to allow the movable jaw to slide more easily.
3. Keep the vise ways clean. Allowing chips to get under the movable vise jaw can cause damage to the vise.
4. Keep the machine’s hand grip clean in order to prevent accidental slippage during use.
5. If you do not intend to use the machine for longer than a week, clean it and store it in a cool, dry place out of the
reach of children. Relieve blade tension; this will prolong the life of the blade and prevent warpage.
6. Check the blade condition daily. Replace the blade if it is dull, warped, or shows other signs of damage.
