GENERAL SAFETY INSTRUCTIONS

;! i

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.

MAKE WORKSHOP KID-PROOF 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 RIGHTTOOL. Don't force the tool or the

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 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.

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.

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

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 toolis
equipped with an electriccord that h_s an equipment

groundingconductor 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 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.

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.

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.

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 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.

12 Replace the blade wheel. Push the wheel on firmly until

it is touching the saw pulley. Replace and tighten the

flange and nut.

13. Reinstall the blade (See iNSTALLING BLADES Section
on page ).

14. Adjust the blade tension, tracking, and the upper and
lower blade guides and bearings before operating the

band saw.

To avoid injury, the blade tension, tracking, and upper and
tower guides and bearings musl be properly adjusted before

operating the band saw. (See ADJUSTMENT INSTRUCTIONS
section)

FIG. Z

BLADE WHEEL TIRES

Pitch and sawdust that build up on the tires should be
removed with a stiff brush or scrape 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
