GENERAL SAFETY RULES

WARNING!

READ AND UNDERSTAND ALL INSTRUCTIONS

Failure to follow all instructions listed below may result in

electric shock, ﬁre, and/or serious injury.

SAVE THESE INSTRUCTIONS

WORK AREA

Keep your work area clean and well lit. Cluttered benches and dark areas invite

accidents.

Do not operate power tools in explosive atmospheres, such as in the pres-

ence of ﬂammable liquids, gases, or dust. Power tools create sparks which may

ignite the dust or fumes.

Keep bystanders, children, and visitors away while operating a power tool.

Distractions can cause you to lose control. Protect others in the work area from

debris such as chips and sparks. Provide barriers or shields as needed.

ELECTRICAL SAFETY

Grounded tools must be plugged into an outlet properly installed and grounded

in accordance with all codes and ordinances. Never remove the grounding

prong or modify the plug in any way. Do not use any adapter plugs. Check with

a qualiﬁed electrician if you are in doubt as to whether the outlet is properly

grounded. If the tools should electrically malfunction or break down, grounding

provides a low resistance path to carry electricity away from the user.

Double insulated tools are equipped with a polarized plug (one blade is wider

than the other). This plug will ﬁt in a polarized outlet only one way. If the plug

does not ﬁt fully in the outlet, reverse the plug. If it still does not ﬁt, contact

a qualiﬁed electrician to install a polarized outlet. Do not change the plug

in any way. Double insulation eliminates the need for the three wire grounded

power cord and grounded power supply system.

Avoid body contact with grounded surfaces such as pipes, radiators, ranges,

and refrigerators. There is an increased risk of electric shock if your body is

grounded.

Do not expose power tools to rain or wet conditions. Water entering a power

tool will increase the risk of electric shock.

Do not abuse the Power Cord. Never use the Power Cord to carry the tools or

pull the Plug from an outlet. Keep the Power Cord away from heat, oil, sharp

edges, or moving parts. Replace damaged Power Cords immediately. Dam-

aged Power Cords increase the risk of electric shock.

When operating a power tool outside, use an outdoor extension cord marked

“W-A” or “W”. These extension cords are rated for outdoor use, and reduce the

risk of electric shock.

PERSONAL SAFETY

Stay alert. Watch what you are doing, and use common sense when operat-

ing a power tool. Do not use a power tool while tired or under the inﬂuence

of drugs, alcohol, or medication. A moment of inattention while operating power

tools may result in serious personal injury.

Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts.

Loose clothes, jewelry, or long hair can be caught in moving parts.

Avoid accidental starting. Be sure the Power Switch is off before plugging

in. Carrying power tools with your ﬁnger on the Power Switch, or plugging in power

tools with the Power Switch on, invites accidents.

SKU 93507 For technical questions, please call 1-800-444-3353. Page 4

Remove adjusting keys or wrenches before turning the power tool on. A

wrench or a key that is left attached to a rotating part of the power tool may result

in personal injury.

Do not overreach. Keep proper footing and balance at all times. Proper footing

and balance enables better control of the power tool in unexpected situations.

Use safety equipment. Always wear eye protection. Dust mask, nonskid safety

shoes, hard hat, or hearing protection must be used for appropriate conditions.

TOOL USE AND CARE

Use clamps (not included) or other practical ways to secure and support the

workpiece to a stable platform. Holding the work by hand or against your body

is unstable and may lead to loss of control.

Do not force the tool. Use the correct tool for your application. The correct

tool will do the job better and safer at the rate for which it is designed.

Do not use the power tool if the Power Switch does not turn it on or off. Any

tool that cannot be controlled with the Power Switch is dangerous and must be

replaced.

Disconnect the Power Cord Plug from the power source before making any

adjustments, changing accessories, or storing the tool. Such preventive safety

measures reduce the risk of starting the tool accidentally.

Store idle tools out of reach of children and other untrained persons. Tools

are dangerous in the hands of untrained users.

Maintain tools with care. Keep cutting tools sharp and clean. Properly main-

tained tools with a sharp cutting edge are less likely to bind and are easier to control.

Do not use a damaged tool. Tag damaged tools “Do not use” until repaired.

Check for misalignment or binding of moving parts, breakage of parts, and any

other condition that may affect the tool’s operation. If damaged, have the tool

serviced before using. Many accidents are caused by poorly maintained tools.

Use only accessories that are recommended by the manufacturer for your

model. Accessories that may be suitable for one tool may become hazardous

when used on another tool.

SERVICE

Tool service must be performed only by qualiﬁed repair personnel. Service or

maintenance performed by unqualiﬁed personnel could result in a risk of injury.

When servicing a tool, use only identical replacement parts. Follow instruc-

tions in the “Inspection, Maintenance, And Cleaning” section of this manual.

SKU 93507 For technical questions, please call 1-800-444-3353. Page 5

Use of unauthorized parts or failure to follow maintenance instructions may create

a risk of electric shock or injury.

SPECIFIC SAFETY RULES

Maintain labels and nameplates on the Bandsaw. These carry important infor-

mation. If unreadable or missing, contact Harbor Freight Tools for a replacement.

Always wear safety impact eye goggles and heavy work gloves

when using the Bandsaw. Using personal safety devices reduce the

risk for injury. Safety impact eye goggles and heavy work gloves are available from Harbor Freight Tools. Heavy work boots, along with other work clothing, are also recommended during use.

Maintain a safe working environment. Keep the work area well lit. Make sure

there is adequate surrounding workspace. Always keep the work area free of ob-

structions, grease, oil, trash, and other debris. Do not use a power tool in areas

near ﬂammable chemicals, dusts, and vapors. Do not use this product in a damp

or wet location.

Avoid unintentional starting. Make sure you are prepared to begin work before

turning on the Bandsaw.

Never leave the Bandsaw unattended when it is plugged into an electrical

outlet. Turn off the tool, and unplug it from its electrical outlet before leaving.

Make sure the Bandsaw is located on a ﬂat, level, sturdy surface capable of

supporting the weight of the Saw and workpieces. Always “chock” the Wheels

to prevent the Bandsaw from accidentally moving.

Make sure the Table of the Bandsaw and surrounding area are clear with the

exception of the workpiece to be cut.

Before using the Bandsaw, check to make sure the Saw Blade is properly

mounted and is not cracked or bent.

Industrial applications must follow OSHA guidelines.

Never stand on the Bandsaw. Serious injury could result if the Bandsaw is tipped

or if the rotating Saw Blade is accidently contacted.

ported. If necessary, use a roller stand (not included).

Do not lean on the Bandsaw when the tool is in its upright position.

When moving the Bandsaw, always have its Head lowered to its horizontal

position.

Allow the Saw Blade to rotate to full speed before feeding a workpiece into

the Blade. When turning off the Bandsaw, allow the Saw Blade to spin down and

stop on its own. Do not press against the Saw Blade to stop it.

To avoid accidental injury, always wear heavy duty work gloves when chang-

ing the Saw Blade.

The Saw Blade will become hot while cutting. Allow the Saw Blade to completely

cool before handling.

Do not force the workpiece into the Saw Blade when cutting. Apply moderate

pressure, allowing the Saw Blade to cut without being forced.

GROUNDING

WARNING!

Improperly connecting the grounding wire can result in the risk of electric shock. Check with a qualiﬁed electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the power cord plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the power cord or plug is damaged. If damaged, have it repaired by a service facility before use. If the plug will not ﬁt the outlet, have a proper outlet installed by a qualiﬁed electrician.

GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS

SKU 93507 For technical questions, please call 1-800-444-3353. Page 8

Tools marked with “Grounding Required” have a three wire cord and three prong grounding plug. The plug must be connected to a properly grounded outlet. If the tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user, reducing the risk of electric shock. (See Figure A.)

The grounding prong in the plug is connected through the green wire inside the cord to the grounding system in the tool. The green wire in the cord must be the only wire connected to the tool’s grounding system and must never be attached to an electrically “live” terminal. (See Figure A.)

Your tool must be plugged into an appropriate outlet, properly installed and grounded in accordance with all codes and ordinances. The plug and outlet should look like those in the following illustration. (See Figure A.)

3-PRONG PLUG

FIGURE A

FIGURE B

DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS

Tools marked “Double Insulated” do not require grounding. They have a special double insulation system which satisﬁes OSHA requirements and complies with the applicable standards of Underwriters Laboratories, Inc., the Canadian Standard Association, and the National Electrical Code. (See Figure B.)

Double insulated tools may be used in either of the 120 volt outlets shown in the preceding illustration. (See Figure B.)

EXTENSION CORDS

Grounded tools require a three wire extension cord. Double Insulated tools can use either a two or three wire extension cord.

As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage.

(See Figure C, next page.)

The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge cord.

(See Figure C.)

When using more than one extension cord to make up the total length, make sure each cord contains at least the minimum wire size required. (See Figure C.)

If you are using one extension cord for more than one tool, add the nameplate am- peres and use the sum to determine the required minimum cord size.

(See Figure C.)

If you are using an extension cord outdoors, make sure it is marked with the sufﬁx “W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.

SKU 93507 For technical questions, please call 1-800-444-3353. Page 9

Make sure your extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualiﬁed electrician before using it.

Protect your extension cords from sharp objects, excessive heat, and damp or wet areas.
