General Power Tool Safety Warnings

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.

SAVE ALL WARNINGS AND INSTRUCTIONS

FOR FUTURE REFERENCE

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1)WORK AREA SAFETY

a)Keep work area clean and well lit. Cluttered or dark areas invite accidents.

b)Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

c)Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

2)ELECTRICAL SAFETY

a)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. Unmodified plugs and matching outlets will reduce risk of electric shock.

b)Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

c)Do not expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk of electric shock.

d)Do not abuse the cord. Never use the cord for carrying, 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.

e)When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

f)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.

3)PERSONAL SAFETY

a)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 inattention while operating power tools may result in serious personal injury.

b)Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, nonskid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

c)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.

d)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.

e)Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

f)Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.

g)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.

4)POWER TOOL USE AND CARE

a)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.

b)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.

c)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.

d)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.

e)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.

f)Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

g)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.

5)BATTERY TOOL USE AND CARE

a)Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of

2

battery pack may create a risk of fire when used with another battery pack.

b)Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.

c)When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.

d)Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

6)SERVICE

a)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.

Additional Safety Rules – Portable Band

Charging Procedure (Fig. 1)

DANGER: Electrocution hazard. 120 volts are present at charging terminals. Do not probe with conductive objects. Electric shock or electrocution may result.

1.Plug the charger into an appropriate outlet before inserting battery pack.

2.Insert the battery pack (O) into the charger, as shown in Figure 1, making sure the pack is fully seated in charger. The red (charging) light will blink continuously indicating that the charging process has started.

3.The completion of charge will be indicated by the red light remaining ON continuously. The pack is fully charged and may be used at this time or left in the charger.

Indicator Light Operation

Charge Indicators

Some chargers are designed to detect certain problems that can arise with battery packs. Problems are indicated by the red light flashing at a fast rate. If this occurs, re-insert battery pack into the charger. If the problem persists, try a different battery pack to determine if the charger is OK. If the new pack charges correctly, then the original pack is defective and should be returned to a service center or other collection site for recycling. If the new battery pack elicits the same trouble indication as the original, have the charger tested at an authorized service center.

HOT/COLD PACK DELAY

Some chargers have a Hot/Cold Pack Delay feature: when the charger detects a battery that is hot, it automatically starts a Hot Pack Delay, suspending charging until the battery has cooled. After the battery has cooled, the charger automatically switches to the Pack Charging mode. This feature ensures maximum battery life. The red light flashes long, then short while in the Hot Pack Delay mode.

PROBLEM POWER LINE

Some chargers have a Problem Power Line indicator. When the charger is used with some portable power sources such as generators or sources that convert DC to AC, the charger may temporarily suspend operation, flashing the red light with two fast blinks followed by a pause. This indicates the power source is out of limits.

LEAVING THE BATTERY PACK IN THE CHARGER

The charger and battery pack can be left connected with the red light glowing indefinitely. The charger will keep the battery pack fresh and fully charged.

NOTE: A battery pack will slowly lose its charge when kept out of the charger. If the battery pack has not been kept on maintenance

8

charge, it may need to be recharged before use. A battery pack may also slowly lose its charge if left in a charger that is not plugged into an appropriate AC source.

WEAK BATTERY PACKS: Chargers can also detect a weak battery pack. Such batteries are still usable but should not be expected to perform as much work. The charger will indicate to replace battery pack.

Important Charging Notes

1.Longest life and best performance can be obtained if the battery pack is charged when the air temperature is between 65°F and 75°F (18°–24°C). DO NOT charge the battery pack in an air temperature below +40°F (+4.5°C), or above +105°F (+40.5°C). This is important and will prevent serious damage to the battery pack.

2.The charger and battery pack may become warm to touch while charging. This is a normal condition, and does not indicate a problem. To facilitate the cooling of the battery pack after use, avoid placing the charger or battery pack in a warm environment such as in a metal shed, or an uninsulated trailer.

3.If the battery pack does not charge properly:

a.Check operation of receptacle by plugging in a lamp or other appliance;

b.Check to see if receptacle is connected to a light switch which turns power off when you turn out the lights;

c.Move charger and battery pack to a location where the surrounding air temperature is approximately 65°F–75°F (18°– 24°C);

d.If charging problems persist, take the tool, battery pack and charger to your local service center.

4.The battery pack should be recharged when it fails to produce sufficient power on jobs which were easily done previously. DO NOT CONTINUE to use under these conditions. Follow the charging procedure. You may also charge a partially used pack whenever you desire with no adverse affect on the battery pack.

5.Under certain conditions, with the charger plugged into the power supply, the exposed charging contacts inside the charger can be shorted by foreign material. Foreign materials of a conductive nature such as, but not limited to, grinding dust, metal chips, steel wool, aluminum foil, or any buildup of metallic particles should be kept away from charger cavities. Always unplug the charger from the power supply when there is no battery pack in the cavity. Unplug charger before attempting to clean.

6.Do not freeze or immerse charger in water or any other liquid.

WARNING: Shock hazard. Don’t allow any liquid to get inside charger. Electric shock may result.

CAUTION: Never attempt to open the battery pack for any reason. If the plastic housing of the battery pack breaks or cracks, return to a service center for recycling.

Storage Recommendations

1.The best storage place is one that is cool and dry away from direct sunlight and excess heat or cold.

2.Long storage will not harm the battery pack or charger. Under proper conditions, they can be stored up to 3 years.

Blade Selection

In general, first consider the size and shape of the work, and the type of material to be cut. Remember, for the most efficient cutting, the coarsest tooth blade possible should be used in a given application, because the coarser the tooth, the faster the cut. In selecting the appropriate number of teeth per inch of the band saw blade, at least two teeth should contact the work surface when the blade is rested against the workpiece. As a rule of thumb, soft materials usually require coarse tooth blades, while hard materials require fine tooth blades.

Where a smoother finish is important, select one of the finer tooth blades.

Select the appropriate band saw blade according to the material type, dimensions, and number of teeth. See Blade Description chart. The following table is intended as a general guide only. Determine the type of material and dimension of the workpiece and select the most appropriate band saw blade.

NOTICE: Never use the band saw to cut resin materials which are subject to melting. Melting of resin material caused by high heat

2.Turn the saw over and place it on a workbench or table with the motor to the left.

3.Begin removing the blade at the blade guard (L) and continue around the pulleys (K). When removing the blade, tension may be released and the blade may spring free. SAW BLADES ARE SHARP. USE CARE IN HANDLING THEM.

4.Inspect the guide rollers (F1, F2) and remove any large chips which may be lodged in them. Lodged chips can prevent rotation of the guide rollers and cause flat spots on the guide rollers.

5.Rubber tires (M) are mounted on the pulleys (K). The rubber tires should be inspected for looseness or damage when changing the blade. Wipe any chips from the rubber tires on the pulleys. This will extend tire life and keep the blade from slipping. If any looseness or damage occurs, the tool should be brought to an authorized DEWALT service center for repair or replacement as soon as possible. Continued use of the tool with loose or damaged rubber tires will cause unstable travel of the band saw blade.

4.Make sure that the blade is fully inserted into the guide rollers and positioned squarely against the rubber tires.

5.Rotate the blade tension lever (H) counterclockwise until it stops and then gently turn the saw over so that the pulleys rest on your work bench or table. Make sure the teeth face away from the bandsaw (Fig. 2, 5).

6.Turn the saw on and off a few times to ensure that the blade is seated properly.

OPERATION

WARNING: To reduce the risk of serious personal injury, turn tool off and remove battery pack before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury.

Cutting

Refer to Figure 9 for recommended cutting positions for various materials.

NOTE: Select and use a band saw blade that is most appropriate for the material being cut. See Blade Description.

This portable band saw may be hung using the hang hook (J). Hang tool on a pipe vise or other suitable, stable structure (Fig. 3).

WARNING: To reduce the risk of injury, only use hang hook to support the weight of the tool. Never rely on the hang hook for your own support or to help you maintain your balance.

WARNING: Never attempt to use this tool by resting it upside down on a work surface and bringing the material to the tool. Always securely clamp the workpiece and bring the tool to the workpiece, securely holding the tool with two hands as shown in Figure 8.

1.Mount the material to be cut solidly in a vise or other clamping device.

2.Bring the work stop (E) into contact with the workpiece. Turn the saw on.

FIG. 8

3.When saw reaches desired rotation speed, slowly and gently tilt the main body of the tool to bring the band saw blade into contact with the workpiece. Do not apply additional pressure in excess of the weight of the main body of the tool. Carefully avoid bringing the band saw blade suddenly and heavily into contact with the upper surface of the workpiece. This will cause serious damage to the band saw blade. To obtain maximum service life of the band saw blade, ensure there is no sudden impact at the beginning of the cutting operation.

4.As shown in Figure 8, straight cutting can be accomplished by keeping the band saw blade aligned with the side surface of the motor housing. Any twisting or cocking of the blade will cause the cut to go offline and decrease the life of the blade.

NOTICE: During cutting, if the band saw becomes locked or jammed in the workpiece material, release the switch immediately to avoid damage to the band saw blade and motor.

5.The tool’s own weight provides the most efficient downward cutting pressure. Added operator pressure slows the blade and reduces blade life.

6.End pieces, which would be heavy enough to cause injury when they drop, after cut-off, should be supported. Safety shoes are strongly recommended. End pieces may be hot.

7.Hold the saw firmly in both hands so that the saw does not fall against clamped or supported material when the cut is completed.

Tips for Better Cutting

The following recommendations should be used as a guide. Results may vary with the operator and the particular material being cut.

•Never twist the band saw blade during cutting operation.

•Never use liquid coolants with portable band saws. Use of liquid coolants will cause build-up on tires and reduce performance.

•If excessive vibration occurs during the cut, ensure that the material being cut is is securely clamped down. If vibration continues, change the band saw blade.

MAINTENANCE
