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 120',/,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.
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 filter out microscopic particles.

GENERAL SAFETY INSTRUCTIONS
BEFORE USING THE BAND SAW
Safety is a combination of common sense, staying alert and
knowing how to use your 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 this entire instruction
manual. LEARN the tool's applications, limitations, and
possible hazards.
2. KEEP GUARDS IN PLACE and in working order.
3. REMOVE ADJUSTING KEYS AND WRENCHES. Form
the 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 A 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 the work area.
7.

11.
MAKE WORKSHOP KID-PROOF with padlocks, master
switches, or by removing starter keys.
DON'T FORCE THE TOOL. It will do the job better and
safer at the rate for which it was designed.
USE THE RIGHTTOOL. Don't force the tool or the
attachment to do a job for which it was not designed.
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 loss of power
which wilt cause the tool to overheat. The table on page
5 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 numbeq the
heavier the cord.

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
THE POWER OFF. Don't leave the tool until it comes to
a complete stop,
21. DON'T OVERREACH. Keep proper footing and balance
at all times.
WEAR PROPER APPAREL. DO NOT wear loose 22.
clothing, gloves, neckties, rings, bracelets, or other
jewelry which may get caught in moving parts. Non-slip
footwear is recommended. Wear protective hair covering
to contain long hair. 23.

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 riskof electric shock. This tool is
equipped with an electric cord that h_s an equipment
groundingconductor and a grounding plug. The plug MUST
be plugged into a matching receptaclethat is properly
installed and grounded in accordance with ALL local codes
and ordinances.
DO NOT MODIFYTHE 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 the 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 lag 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. FIGURE A
shows a 3-prong electrical plug and receptacle that has a
grounding conductor, tf 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 PROPER GROUNDED OUTLET CAN BE
INSTALLED BY A QUALIFIED ELECTRICIAN. 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.

BLADE TENSION (FIG. M)
To avoid injury, turn the switch OFF and disconnect the saw
from the power source before rnaking any adjustments,
NEVER make tension adjustments with the machine running.
The gauge (1) on the bracket (2) at the rear of the upper
wheel housing indicates the proper tension for the various
blade widths.
1. Set the blade tension gauge to correspond with the width
of the blade in use.
2. Turn the blade tension knob (3) clockwise, raising the
upper wheel to tighten the blade. Turn the knob
counterclockwise to lower the upper wheel, loosening
the blade.
3. As you become familiar with the saw, you may want to
change the tension settings.
NOTE: Changes in blade width and type of material
being cut will have an effect on the blade tension. Too
much or too little tension could break the blade. When
the band saw is not in use, relax the blade tension.
F_G. M
If the blade moves toward the front of the wheel, turn the
tracking knob (5) on the rear of the band saw clockwise.

GENERAL CUTTING
For your safety, read and understand all GENERAL and
SPECIFIC SAFETY INSTRUCTIONS on pages 3 - 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 biades need little pressure for cutting. Steadily
move the workpiece against the blade without forcing it.
16 :
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.
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 kerr, 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. V)
1. Adjust the guide assembly to 1/8" above 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 1/4" wide blade will cut a minimum diameter of
approximately 1-1/2".
FIG. V
Minimum
2-1/Z'D Circle Diameter
1/2" Blade Width
BLADE SELECTION (FIG. W)
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 bandsaw,
purchase blades in widths up to 1/2", and a length of 80".
Do not cut ferrous metals with this band saw.
Common causes of blade breakage:
• Poor guide alignment and adjustment.
o Forcing or twisting a wide blade around a short radius.
• Feeding too fast.
Dull teeth or not enough set.
Too much blade tension.
o 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.

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 table 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 Craftsman Gum and Pitch
Remover.
NOTE: Do not immerse the support bearings in the gum and
pitch remover.
Put a thin coat of paste wax on the table so that the wood
slides easily while cutting.
