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.
2
English
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, non-
skid 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 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.
3
English
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
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 firmly 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,

any reason. If the battery pack case is cracked or damaged, do not
insert into the charger. Do not crush, drop or damage the battery pack.
Do not use a battery pack or charger that has received a sharp blow,
been dropped, run over or damaged in any way (e.g., pierced with a
nail, hit with a hammer, stepped on). Damaged battery packs should
be returned to the service center for recycling.
WARNING: Fire hazard. Do not store or carry the battery
pack so that metal objects can contact exposed battery
terminals. For example, do not place the battery pack in aprons,
pockets, tool boxes, product kit boxes, drawers, etc., with loose nails,
screws, keys, etc. Transporting batteries can possibly cause
fires if the battery terminals inadvertently come in contact
with conductive materials such as keys, coins, hand tools
and the like. The US Department of Transportation Hazardous
Material Regulations (HMR) actually prohibit transporting batteries in
commerce or on airplanes (e.g., packed in suitcases and carry-on
luggage) UNLESS they are properly protected from short circuits. So
when transporting individual battery packs, make sure that the battery
terminals are protected and well insulated from materials that could
contact them and cause a short circuit.
SPECIFIC SAFETY INSTRUCTIONS FOR LITHIUM ION (Li-Ion)
• Do not incinerate the battery pack even if it is severely
damaged or is completely worn out. The battery pack can
explode in a fire. Toxic fumes and materials are created when
lithium ion battery packs are burned.
• If battery contents come into contact with the skin,
immediately wash area with mild soap and water. If battery
liquid gets into the eye, rinse water over the open eye for 15
minutes or until irritation ceases. If medical attention is needed,
the battery electrolyte is composed of a mixture of liquid organic
carbonates and lithium salts.
• Contents of opened battery cells may cause respiratory
irritation. Provide fresh air. If symptoms persist, seek medical
attention.
WARNING: Burn hazard. Battery liquid may be flammable if
exposed to spark or flame.

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
D
e
WALT rechargeable battery packs. Other types of batteries may
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
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 specifically designed to work together.
• These chargers are not intended for any uses other than
charging D
e
WALT rechargeable batteries. Any other uses may
result in risk of fire, 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
fire, 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.

Blades
This portable band saw is designed to use
.020" (0.5 mm) thick, 1/2" (12.5 mm) wide and
44-7/8" (1140 mm) long blades. DO NOT use .025
(.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, 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
generated during cutting may cause the band saw blade to become

greater versatility. Turn the speed wheel (K) to select the desired speed
(Fig. 2). Speed 1 is the slowest speed; Speed5 is the fastest. Use
speed settings 1–5.
When cutting copper, brass, bronze, aluminum, cast iron, angle iron,
and mild steel, use a higher speed.
When cutting plastic pipe, tougher steels, chrome steel, tungsten
steel, stainless steel, and other problem materials, use low speed.
NOTE: When cutting plastic pipe, higher speeds may melt plastic.
Blade Tracking (Fig. 2)
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.
Your band saw is equipped with an adjustable blade tracking
mechanism which assures proper blade tracking at all times. The back
edge of a properly aligned blade will run lightly against one or both of
the back up rollers in the blade guides. (The pressure between the
edge of the blade and the roller will be very slight and will not damage
either the blade or the roller.)
TO ADJUST THE BLADE TRACKING
1. Use a 1/2" (13 mm) wrench to loosen the adjustment locking
nut (G), shown in Figure 2 by turning it one or two turns
counterclockwise.
2. Use a screwdriver to turn the adjustment screw (H) 1/4 turn.
Turning the screw clockwise will move the blade up toward the
blade guide rollers. Turning the screw counterclockwise will move
the blade down away from the rollers.
3. Adjust so that the back edge of the blade lightly touches the
rollers then securely tighten the adjustment locking nut. (It will be
necessary to insert the battery pack and run the saw to observe
the tracking.)
4. Observe blade tracking between runs and repeat Steps 1–4 as
necessary to achieve proper blade tracking.
WARNING: Make sure the battery is removed if further tracking
adjustment is needed.
ASSEMBLY AND ADJUSTMENTS
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.
Installing and Removing the Battery Pack
(Fig. 1, 2, 5)
NOTE: For best results, make sure your battery pack is fully charged.

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, 4)
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
handle to the right.
3. Begin removing the blade at the upper portion of the blade guard

tension may be released and the blade may spring free. SAW
BLADES ARE SHARP. USE CARE IN HANDLING THEM.
14
English
4. Inspect the guide rollers (F) 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 (P) are mounted on the pulleys (N). 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
e
WALT 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, 4, 7–9)
1. Position the blade so that the teeth are on the bottom and angled
toward the work stop, as shown in Figure 7.
FIG. 7

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.
There are certain applications for which this tool was designed.
This band saw is designed to cut various types of material up to 4-3/4"
(120.7 mm) diameter or 5" (127 mm) x 4-3/4" (120.7 mm) rectangular
shape at 90º.
WARNING: Thoroughly remove any oil or grease from the workpiece
before securing in a vise or other clamping device. If the workpiece
is not secure, it may come loose during the cutting and/or cause
breakage, which may result in serious personal injury.
Cutting
Refer to Figure 12 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 (M, Fig. 4).
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 as shown in Figure 11.
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 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
16
English
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 11,
FIG. 11
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 and sharp.
7. Whenever possible, hold the saw firmly in both hands.
8. DO NOT MAKE ANY SPEED CHANGES UNLESS TOOL HAS
BEEN TURNED OFF.

to Figure 12). Results may vary with the operator and the particular
material being cut.
17
English
• 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.
