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.

6. Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving
parts. Loose clothes, jewelry or long hair can be caught
in moving parts.
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.
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 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
will ensure that the safety of the power tool is maintained.
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 California 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 exposure to these chemicals, work in a well-ventilated area
with approved safety equipment such as dust masks
specially designed to filter out microscopic particles.
SPECIFIC RULES FOR YOUR BAND SAW
WARNING! Do not operate the power tool until you have read and understood the following instructions
and the warning labels.
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 direction.
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 (see “Changing the Saw Blade”,
page 16).
5. Keep hands out of path of saw blade. Never use your
hands to remove sawdust or scrap wood. Use a brush
at all times.
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-approved dust masks or other respiratory protection during operation and cleaning.
6. Always turn off and unplug the band saw before making any adjustments or repair tasks. Never adjust the
band saw or the workpiece while the saw is running.
7. Only use the band saw to cut wood.
PREPARING THE BAND SAW
1. When transporting the band saw, never carry the device by its guards or its accessories.
2. Examine the 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.
6. Never reach around saw blade or reach in back of the
saw blade.
7. The use of accessories or attachments not recommended by the manufacturer may result in a risk of personal injury.
PERSONAL SAFETY
1. Operate in a well ventilated area. Keep the floor area
around the band saw level and free of slippery substances or other tripping hazards.
2. Wear ANSI Z87.1-approved safety goggles to protect
your eyes from saw dust. Use hearing protection to protect 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 interference or pacemaker failure.
SECURE YOUR WORKPIECE
1. To avoid blade binding or loss of control, always secure 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 workpiece.
3. For accuracy of cut, and to avoid blade binding, always use a rip fence or straight edge guide.
4. Use extra caution with very large, very small, or awkwardly-shaped workpieces. Small pieces should be secured with clamps. Do not hold small pieces with your
hand because your fingers might go under the blade
guard.

SPECIFIC RULES FOR YOUR BAND SAW
WARNING! Do not operate the power tool until you have read and understood the following instructions
and the warning labels.
5. Never hand-hold a workpiece that is too small to be
clamped, as it can be launched away and cause injury. Use proper support and guides to secure the small
workpiece.
6. Support round work properly (use a V block or press
it against the miter gauge) to prevent it from rolling and
the blade from biting.
7. Plan intricate or small work carefully to avoid pinching the blade. Avoid awkward operations and hand positions to prevent accidental contact with the blade.
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 rotation of the blade only.
4. If you are interrupted when operating the saw, complete 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, ensuring 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 surfaces are not used.
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. Adjust
the upper blade guide to suit the thickness of the workpiece.
10. If a cut does not extend to the edge of the workpiece, 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.
12. Always adjust the upper blade guide to cover the
blade after use.
6. Do not use the band saw unless all guards are in
place. Do not operate with any guard disabled, damaged, or removed. Moving guards must move freely and
close instantly.

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. 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.
