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, ﬁ re 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 ﬂ ammable 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. Unmodiﬁ ed 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

English

tool while you are tired or under the inﬂ uence 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

English

the off position before connecting to power source and/ or battery pack, picking up or carrying the tool. Carrying

power tools with your ﬁ nger 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 speciﬁ ed by the

manufacturer. A charger that is suitable for one type of battery

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

b) Use power tools only with speciﬁ cally designated battery

packs. Use of any other battery packs may create a risk of injury and ﬁ re.

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 ﬁ re.

d) Under abusive conditions, liquid may be ejected from

the battery; avoid contact. If contact accidentally occurs, ﬂ ush 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 qualiﬁ ed repair person

using only identical replacement parts. This will ensure that

the safety of the power tool is maintained.

Additional Safety Rules – Portable Band Saws

• Hold power tool by insulated gripping surfaces when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessories contacting a “live”

wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

• Keep hands away from cutting area and blade.

• Always make sure the portable band saw is clean before

using.

• Always cease operation at once if you notice any abnormality whatsoever.

• Always be sure all components are mounted properly and securely before using tool.

• Always handle the band saw blade with care when mounting or removing it.

• Always keep your hands out of the line of the band saw blade.

• Always wait until the motor has reached full speed before starting a cut.

• Always keep handles dry, clean, and free of oil and grease.

Hold the tool ﬁ rmly when in use.

• Always be alert at all times, especially during repetitive, monotonous operations. Always be sure of position of your hands relative to the blade.

• Never remove work stop.

• Stay clear of end pieces that may fall after cutting off. They may be hot, sharp and/or heavy. Serious personal injury may result.

• Air vents often cover moving parts and should be avoided. Loose clothes, jewelry or long hair can be caught in moving parts.

WARNING: ALWAYS use safety glasses. Everyday eyeglasses are

NOT safety glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:

• ANSI Z87.1 eye protection (CAN/CSA Z94.3),

• ANSI S12.6 (S3.19) hearing protection,

• NIOSH/OSHA/MSHA respiratory protection.

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 and cement and other masonry products, and

• 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 those dust masks that are specially designed to ﬁ lter out microscopic particles.

• Avoid prolonged contact with dust from power sanding,

sawing, grinding, drilling, and other construction activities.

English

Wear protective clothing and wash exposed areas with soap

Important Safety Instructions for All Battery Chargers

SAVE THESE INSTRUCTIONS: This manual contains important safety and operating instructions for battery chargers.

• Before using the charger, read all instructions and cautionary markings on the charger, battery pack and product using the battery pack.

English

WARNING: Shock hazard. Do not allow any liquid to get inside the

charger. Electric shock may result.

CAUTION: Burn hazard. To reduce the risk of injury, charge only

EWALT rechargeable battery packs. Other types of batteries may

D overheat and burst resulting in personal injury and property damage.

NOTICE: Under certain conditions, with the charger plugged into the power supply, the charger can be shorted by foreign material. Foreign materials of a conductive nature, such as, but not limited to, grinding

English

dust, metal chips, steel wool, aluminum foil or any buildup of metallic particles should be kept away from the charger cavities. Always unplug the charger from the power supply when there is no battery pack in the cavity. Unplug the charger before attempting to clean.

• DO NOT attempt to charge the battery pack with any chargers other than the ones in this manual. The charger and battery pack are speciﬁ cally designed to work together.

• These chargers are not intended for any uses other than

charging D

EWALT rechargeable batteries. Any other uses may

result in risk of ﬁ re, electric shock or electrocution.

• Do not expose the charger to rain or snow.

• Pull by the plug rather than the cord when disconnecting the charger. This will reduce the risk of damage to the electric plug and cord.

• Make sure that the cord is located so that it will not be

stepped on, tripped over or otherwise subjected to damage or stress.

• Do not use an extension cord unless it is absolutely necessary. Use of improper extension cord could result in risk of

ﬁ re, electric shock or electrocution.

• When operating a charger outdoors, always provide a dry

location and use an extension cord suitable for outdoor use.

Use of a cord suitable for outdoor use reduces the risk of electric shock.

• An extension cord must have adequate wire size (AWG or American Wire Gauge) for safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that is, 16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. When using more than one extension to make up the total length, be sure each individual extension contains at least the minimum wire size. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The lower the gauge number, the heavier the cord.

Charge Indicators

This charger is designed to detect certain problems that can arise. Problems are indicated by the red light ﬂ ashing at a fast rate. If this occurs, re-insert the battery pack into the charger. If the problem persists, try a different battery pack to determine if the charger is working properly. 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 and the battery pack tested at an authorized service center.

HOT/COLD DELAY

This charger has a hot/cold delay feature: when the charger detects a battery that is hot, it automatically starts a 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 ﬂ ashes long, then short while in the hot/cold delay mode.

English

LEAVING THE BATTERY PACK IN THE CHARGER

The charger and battery pack can be left connected with the charge indicator showing Pack Charged.

WEAK BATTERY PACKS: Weak batteries will continue to function but should not be expected to perform as much work.

FAULTY BATTERY PACKS: This charger will not charge a faulty battery pack. The charger will indicate faulty battery pack by refusing to

English

light or by displaying problem pack or charger.

NOTE: This could also mean a problem with a charger. 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, ﬂ ashing the red light with two fast blinks followed by a pause. This indicates the power source is out of limits.

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 the 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. A cold battery pack will charge at about half the rate of a warm

battery pack. The battery pack will charge at that slower rate throughout the entire charging cycle and will not return to maximum charge rate even if the battery pack warms.

4. 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 the 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.

5. The battery pack should be recharged when it fails to produce sufﬁ cient 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 effect on the battery pack.

6. 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 the charger before attempting to clean.

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

WARNING: Shock hazard. Don’t allow any liquid to get inside the

charger. Electric shock may result.

WARNING: Burn hazard. Do not submerge the battery pack in

any liquid or allow any liquid to enter the battery pack. 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. For long storage, it is recommended to store a fully charged battery pack in a cool dry place out of the charger for optimal results.

NOTE: Battery packs should not be stored completely depleted of charge. The battery pack will need to be recharged before use.

NOTE: The worklight is for lighting the immediate work surface and is not intended to be used as a ﬂ ashlight.

Blades

This portable band saw is setup for use with .02" (0.5 mm) thick, 1/2" (12.5 mm) wide and 32" (813 mm) long blades. DO NOT use .025" (0.64 mm) thick blades.

WARNING: The use of any other blade or accessory might be

hazardous. DO NOT use any other type of accessory with your band saw. Blades used on stationary band saws are of different thickness. Do not attempt to use them on your portable unit.

Blade Selection

In general, ﬁ rst consider the size and shape of the work, and the type of material to be cut. Remember, for the most efﬁ cient 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

English

FIG. 2

English

coarse tooth blades, while hard materials require ﬁ ne tooth

blades. Where a smoother ﬁ nish is important, select one of the ﬁ ner 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 generated during cutting may cause the band saw blade to become bound to the material, possibly resulting in overload and burn-out of the motor.

Removing and Installing Blades

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

An accidental start-up can cause injury.

CAUTION: Cut Hazard. Blade tension lever is under spring pressure. Maintain control of lever when releasing blade tension.

TO REMOVE BLADE (FIG. 2, 3)

1. Rotate the blade tension lever (I) clockwise until it stops to

release tension in blade (refer to Figure 2).

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

battery to the right (refer to Figure 3).

3. Begin removing the blade at the upper portion of the blade guard (M) and continue around the pulleys (L). 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 (G) and remove any large chips which may be lodged in them. Lodged chips can prevent rotation of the guide rollers and cause ﬂ at spots on the guide rollers.

5. Rubber tires (N) are mounted on the pulleys (L). 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 D

EWALT 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.

TO INSTALL BLADE (FIG. 2, 3, 5–7)

1. Position the blade so that the teeth are on the bottom and angled toward the work stop, as shown in Figures 2 and 5.

2. Slip the blade into the guide rollers, as shown in Figure 6.

3. Holding the blade in the guide rollers, place it around both pulleys (L) and through the work stop (F), as shown in Figure7.

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 (I) 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 the 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 (K, Fig. 3). Hang tool on a pipe vise or other suitable, stable structure.

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 whenever possible 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 (F) into contact with the workpiece while

keeping the blade off of the workpiece. Turn the saw on.

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

English

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 ofﬂ ine and decrease the life of the blade.

English

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 efﬁ cient downward cutting pressure. Added operator pressure slows the blade and reduces blade life.

FIG. 8

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 and sharp.

7. Whenever possible, hold the saw ﬁ rmly in both hands. If an application requires only one hand to be placed on the saw, be sure to keep the second hand clear of the blade area and do not allow the saw to fall against the clamped or supported material when the cut is complete.

Tips for Better Cutting

The following recommendations should be used as a guide (refer to Figure 9). 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.
