To avoid electrical hazards, fire hazards, or damage to the tool, use proper circuit protection. Use a separate electrical circuit for your tools. Your Band Saw is wired at the factory for 120V operation. Connect to a 120V, 15 AMP branch circuit and use a 15 Amp time delay fuse or circuit breaker. To avoid shock or fire, replace power cord immediately if it is worn, cut or damaged in any way.
WARNING
Some dust created by power sanding, sawing, grinding, drilling and other construction activities contains chemicals known to the state of California to cause cancer, birth defects or other reproductive harm. 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 and work with approved safety equipment such as dust masks that are specially designed to filter out microscopic particles.
WARNING
SAVE THESE INSTRUCTIONS
GENERAL SAFETY INSTRUCTIONS
BEFORE USING THE BAND SAW
Safety is a combination of common sense, staying alert and knowing how to use this Band Saw.
To avoid mistakes that could cause serious injury, do not plug the Band Saw in until you have read and understood the following:
1. READ and become familiar with the entire Operator’s Manual. LEARN the tool’s application, limitations and possible hazards.
2. KEEP GUARDS IN PLACE and in working order.
3. REMOVE ADJUSTING KEYS AND WRENCHES. Form a habit of checking to see that keys and adjusting wrenches are removed from the tool before turning ON.
4. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
5. DON’T USE IN DANGEROUS ENVIRONMENT. Don’t use power tools in damp or wet locations, or expose them to rain. Keep work area well lighted.
6. KEEP CHILDREN AWAY. All visitors should be kept at a safe distance from work area.
7. MAKE WORKSHOP CHILDPROOF with padlocks, master switches, or by removing starter keys.
8. DON’T FORCE THE TOOL. It will do the job better and safer at the rate for which it was designed.
9. USE THE RIGHT TOOL. Do not force tool or attachment to do a job for which it was not designed.
10. USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will result in a drop in line voltage and in loss of power that will cause the tool to overheat. The table on page 6 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.
11. WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry that may get caught in moving parts. Non-slip footwear is recommended. Wear protective hair covering to contain long hair.
12. ALWAYS WEAR EYE PROTECTION. Any Band Saw
can throw foreign objects into the eyes that could cause permanent eye damage. ALWAYS wear Safety Goggles (not glasses) that comply with ANSI Safety Standard Z87.1. Everyday eyeglasses have only impact-resistance lenses. They ARE NOT safety glasses. Safety Goggles are available at HITACHI. NOTE: Glasses or goggles not in compliance with ANSI Z87.1 could cause serious injury.
13. WEAR A FACE MASK OR DUST MASK. Sawing
operation produces dust.
14. SECURE WORK. Use clamps or a vise to hold work
when practical. It’s safer than using your hand and it frees both hands to operate tool.
15. DISCONNECT TOOLS before servicing; when changing
accessories such as blades, bits, cutters, and the like.
16. REDUCE THE RISK OF UNINTENTIONAL STARTING.
Make sure switch is in OFF position before plugging in.
17. USE RECOMMENDED ACCESSORIES. Consult the
Operator’s Manual for recommended accessories. The use of improper accessories may cause serious injury.
18. NEVER STAND ON TOOL. Serious injury could occur if
the tool is tipped or if the cutting tool is unintentionally contacted.
19. CHECK FOR DAMAGED PARTS. Before further use of
the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function – check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced.
20. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER “OFF”. Don’t leave tool until it comes to a complete stop.
21. DON’T OVERREACH. Keep proper footing and balance at all times.
22. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories.
23. DO NOT use power tools in the presence of flammable liquids or gases.
24.
DO NOT OPERATE the tool if you are under the influence of any drugs, alcohol or medication that could affect your ability to use the tool properly.
25. ALWAYS operate the Band Saw in a well-ventilated area and provide for proper dust removal. Use dust collection systems whenever possible. Dust generated from certain materials can be hazardous to your health.

SAFETY
SPECIFIC SAFETY INSTRUCTIONS FOR BAND SAWS
1. TO AVOID INJURY from unexpected movement, make
sure the saw is on a firm, level surface, properly secured to prevent rocking. Make sure there is adequate space for operating. Bolt the saw to a support surface to prevent slipping, walking, or sliding during operation.
2. TURN the saw OFF and unplug the saw before moving it.
3. USE THE CORRECT size and style blade.
4. USE blades rated at 3600 FPM or greater.
5. MAKE SURE the blade teeth point down and towards the
table.
6. BLADE GUIDES, SUPPORT 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 is 1/8 inch above the workpiece.
7. TABLE LOCK HANDLE should be tight.
8. USE EXTRA CAUTION with large, very small or awkward workpieces.
9. USE EXTRA SUPPORTS to prevent workpieces from sliding off the tabletop. Never use another person to support the workpiece.
10. WORKPIECES must be secured so they don’t twist, rock, or slip while being cut.
11. PLAN intricate and small work carefully to avoid pinching the blade. Avoid awkward operation and hand positions to prevent accidental contact with the blade.
12. SMALL PIECES should be secured with jigs or fixtures. Do not hand hold pieces that are so small your fingers are under the blade guard.
13. SUPPORT round work properly (with a V-block or clamped to the miter gauge) to prevent it from rolling and the blade from biting.
14. CUT only one workpiece at a time. Make sure the table is clear of everything except the workpiece and its guides before you turn the saw on.
15. ALWAYS WATCH the saw run before each use. If there is excessive vibration or unusual noise, stop immediately. Turn the saw OFF. Unplug it immediately. Do not start the saw again until the problem has been located and corrected.
16. TO FREE any jammed material, turn the switch OFF. Remove the switch key and unplug the saw. Wait for all moving parts to stop before removing jammed material.
17. DON’T LEAVE the work area until all moving parts are stopped. To childproof the workshop, shut OFF the power to master switches and remove the switch key from the band saw. Store it in a safe place, away from children.
For your own safety, read the entire instruction manual before operating the band saw.
1. Wear eye protection.
2. Do not wear gloves, necktie, or loose clothing.
3. Make sure the saw is on a firm level surface and properly secured.
4. USE ONLY THE RECOMMENDED ACCESSORIES.
5. Use extra caution with very large, very small, or awkward workpieces.
6. Keep hands away from the blade at all times to prevent accidental injury.
7. Do not remove jammed cutoff pieces until the blade has stopped.
8. Maintain proper adjustment of blade tension, blade guides and thrust bearings.
9. Adjust upper guide to just clear the workpiece.
10. Hold the workpiece firmly against the table.
ELECTRICAL REQUIREMENTS
POWER SUPPLY AND MOTOR SPECIFICATIONS
To avoid electrical hazards, fire hazards, or damage to the tool, use proper circuit protection. Use a separate electrical circuit for your tools. Your saw is wired at the factory for 120V operation. Connect to a 120V, 15 Amp circuit and use a 15 Amp time delay fuse or circuit breaker. To avoid shock or fire, if power cord is worn or cut, or damaged in any way, have it replaced immediately.
GROUNDING INSTRUCTIONS
This tool must be grounded while in use to protect the operator from electrical shock.
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN,
grounding provides a path of least resistance for 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 receptacle that is properly installed and grounded in accordance with ALL local codes and ordinances.
DO NOT MODIFY THE PLUG PROVIDED. If it will not fit the receptacle, have the proper receptacle installed by a qualified electrician.
IMPROPER CONNECTION of the equipment-grounding conductor can result in risk of electric shock. The conductor with 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.
CHECK with a qualified electrician or service person if you do not completely understand the grounding instructions, or if you are not sure the tool is properly grounded.

USE ONLY 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool’s plug. Repair or replace damaged or worn cord immediately.
Use a separate electrical circuit for your tools. This circuit must not be less than #12 wire and should be protected with a 15 Amp time delay 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.
This tool is intended for use on a circuit that has a receptacle like the one illustrated in Figure A showing a 3-prong electrical plug and receptacle that has a grounding conductor. If a properly grounded receptacle is not available, an adapter (Figure B) can be used to temporarily connect this plug to a 2-contact ungrounded receptacle. The adapter (Figure B) has a rigid lug extending from it that MUST be connected to a permanent earth ground, such as a properly grounded receptacle box. THE TEMPORARY ADAPTER SHOULD BE USED ONLY UNTIL A QUALIFIED ELECTRICIAN CAN INSTALL A PROPERLY GROUNDED OUTLET. The Canadian Electrical Code prohibits the use of adapters.
CAUTION: In all cases, make certain the receptacle is properly grounded. If you are not sure, have a qualified electrician check the receptacle.
This Band Saw is for indoor use only. Do not expose to rain or use in damp locations.
GUIDELINES FOR EXTENSION CORDS
USE PROPER EXTENSION CORD. Make sure your extension
cord is in good condition. 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 cause overheating. The table below shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number the heavier the cord.
Be 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. Protect your extension cords from sharp objects, excessive heat and damp or wet areas.

1. To turn the band saw ON (I) insert the yellow key (1) into the key slot in the center of the switch.
2. Push the key firmly into the slot, then push switch to the ON position to start the band saw.
3. To turn the band saw OFF (O) push the switch to the down position.
4. Remove the yellow switch key, when the saw has come to a complete stop, by gently pulling it outward.
Remove the switch key whenever the saw is not in use. Place it in a safe place and out of reach of children.
ALWAYS lock the switch OFF when the saw is not in use. Remove the key and keep it in a safe place. In the event of power failure, blown fuse, or tripped circuit breaker, turn the switch OFF and remove the key, preventing an accidental startup when power comes on.
For your safety, read and understand all GENERAL and SPECIFIC SAFETY INSTRUCTIONS on pages 4-5 before using the band saw.
Operating band saws involves a certain amount of hazard. Before attempting regular work, use scrap lumber to check the settings and to get the feel of operating the band saw. Read instructions and plan your work before cutting a workpiece.
Do not turn the power ON until after you have made all adjustments, checked that the guard is in place, and turned the wheel by hand to make sure all parts work properly. Always keep the guide assembly close to your work, 1/8 above the workpiece.
Do not force the workpiece, against the blade. Light contact permits easier cutting and prevents unwanted friction and heating of the blade.
Sharp saw blades need little pressure for cutting. Steadily move the workpiece against the blade without forcing it. To avoid twisting the blade, do not turn sharp corners, saw around corners.
A band saw is basically a “curve-cutting” saw. It is not capable of doing intricate inside cutting as can be done with a scroll saw.
It is also used for straight-line operations such as crosscutting, ripping, mitering, beveling, compound cutting, and resawing.

OPERATION

1
To avoid blade breakage, fire or other damage or injury, NEVER use this band saw to cut ferrous metals.
CUTTING CURVES
When cutting curves, carefully turn the workpiece so the blade follows without twisting. If the curve is so sharp that you repeatedly back up and cut new kerf, use a narrower blade, or a blade with more set (teeth further apart). When a blade has more set, the workpiece turns easier but the cut is rougher.
When changing a cut, do not withdraw the workpiece from the blade. The blade may get drawn off the wheels.
To change a cut, turn the workpiece and saw out through the scrap material area.
When cutting long curves, make relief cuts as you go along.
CIRCLE CUTTING (Fig. P)
1. Adjust the guide assembly to 1/8above the workpiece.
2. Use both hands while feeding the work into the blade. Hold the workpiece firmly against the table. Use gentle pressure. Do not force the work, ALLOW the blade to cut.
3. The smallest diameter circle that can be cut is determined by the width of the blade. For example, a 1/4wide blade will cut a minimum diameter of approximately 1-1/2″.
BLADE SELECTION (Fig. Q)
CAUTION: Blade teeth are sharp. Use care when handling
a saw blade.
For longest wear and best cutting results, use the correct blade thickness width, and temper for the type of material you will cut.
When sawing small curves and delicate work, use narrow blades. Otherwise, use the widest blade possible. For cutting wood and similar materials with this band saw, purchase blades in widths up to 3/8, and a length of 63-1/2″.
Do not cut ferrous metals with this band saw.
Common causes of blade breakage:
• Poor guide alignment and adjusting.
• Forcing or twisting a wide blade around a short radius.
• Feeding too fast.
• Dull teeth or not enough set.
• Too much blade tension.
• Setting top guide assembly too high above the workpiece.
• Lumpy or improperly finished braze or weld on the blade.
• Continuous running of blade when not cutting.
Fig. Q
To avoid possible injury or damage, NEVER use this band saw to cut ferrous metals.
CAUTION: When cutting nonferrous metals, metal shavings can react with wood dust and start a fire. To avoid this:
1. Disconnect any dust collection bag from the band saw.
2. Remove all traces of wood dust from inside the saw.
3. Remove all metal shavings from inside the saw before sawing wood again.

GENERAL MAINTENANCE
• For your own safety, turn switch OFF and remove the plug from power source receptacle before maintaining, cleaning, adjusting, or lubricating your band saw.
• To avoid fire or toxic reaction, never use gasoline, naphtha, acetone, lacquer thinner or similar highly volatile solvents to clean the band saw.
• To avoid eye injury from blowing debris, wear safety goggles when blowing out sawdust.
BAND SAW
Sawdust will accumulate under the table and base. This could cause difficulty in the movement of the body when setting up a band saw cut, and also cause a fire hazard.
Frequently blow out or vacuum up the sawdust.
Keep your band saw clean. Remove the sawdust from the inside. Vacuum or blow out frequently.
Do not allow filth to build up on the table, the guides, or the support bearings. Clean them with gum and pitch remover. NOTE: Do not immerse the support bearing in the gum and pitch remover. Put a thin coat of paste wax on the table so that the wood slides easily while cutting.
BLADE WHEEL TIRES
Pitch and sawdust that build up on the tires, should be removed with a stiff brush or scraped off with a piece of wood. NOTE: To avoid damaging the tires, do not use a sharp knife or any kind of solvent. When the tires become worn they should be replaced. When replacing the tires, stretch them around the wheels but do not glue them on.
MOTOR
Frequently blow or vacuum out any sawdust from the motor.
To avoid electrocution or fire, immediately replace a worn, cut or damaged power cord.
LUBRICATION
All of the bearings are packed with grease at the factory. They require no further lubrication.
BATTERIES
Check the batteries regularly to avoid deterioration. Remove the batteries if you will not be using the worklight for an extended time.
CAUTION: Never put lubricants on the blade while it is spinning.
