• Wear face mask or dust mask if operation is dusty.

• Be alert and think clearly. Never operate power tools when tired, intoxicated or when taking medications

that cause drowsiness.

PREPARE WORK AREA FOR JOB

• Keep work area clean. Cluttered work areas invite accidents.

• Do not use power tools in dangerous environments. Do not use power tools in damp or wet locations. Do not expose power tools to rain.

• Work area should be properly lighted.

• Proper electrical receptacle should be available for

tool. Three-prong plug should be plugged directly

into properly grounded, three-prong receptacle.

• Extension cords should have a grounding prong and

the three wires of the extension cord should be of the correct gauge.

• Keep visitors at a safe distance from work area.

• Keep children out of workplace. Make workshop childproof. Use padlocks, master switches or remove switch keys to prevent any unintentional use of power tools.

PROPOSITION 65 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.

• Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures vary, 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. Always wear

OSHA/NIOSH approved, properly fitting face mask or respirator when using such tools.

WARNING: For your own safety, read all of the instructions and precautions before operating tool.

CAUTION: Always follow proper operating procedures as defined in this manual -- even if you are familiar

with use of this or similar tools. Remember that being careless for even a fraction of a second can result in

severe personal injury.

TOOL SHOULD BE MAINTAINED

• Always unplug tool prior to inspection.

• Consult manual for specific maintaining and adjust- ing procedures.

• Keep tool lubricated and clean for safest operation.

• Remove adjusting tools. Form habit of checking to see that adjusting tools are removed before switch- ing machine on.

• Keep all parts in working order. Check to determine

that the guard or other parts will operate properly

and perform their intended function.

• Check for damaged parts. Check for alignment of moving parts, binding, breakage, mounting and any other condition that may affect a tool's operation.

• A guard or other part that is damaged should be properly repaired or replaced. Do not perform makeshift repairs. (Use parts list provided to order replacement parts.)

KNOW HOW TO USE TOOL

• Use right tool for job. Do not force tool or attachment

to do a job for which itwas not designed.

• Disconnect tool when changing blade.

• Avoid accidental start-up. Make sure that the tool is in the OFF position before plugging in.

• Do not force tool. It will work most efficiently at the rate for which it was designed.

Keep hands away from moving parts and cutting surfaces.

• Never leave tool running unattended. Turn the power off and do not leave tool until it comes to a complete

stop.

• Do not overreach. Keep proper footing and balance. Never stand on tool. Serious injury could occur if tool

is tipped or if blade is unintentionally contacted. Know your tool. Learn the tool's operation, applica-

tion and specific limitations.

Use of improper accessories increases the risk of injury to persons.

Handle workpiece correctly. Protect hands from pos- sible injury.

Turn machine off if it jams. Blade jams when it digs

too deeply into workpiece. (Motor force keeps it

stuck in the work.) Do not remove jammed or cut off pieces until the saw is turned off, unplugged and the

blade has stopped.

WARNING: The operation of any power tool can result in foreign objects being thrown into the eyes, which can

result in severe eye damage. Always wear safety goggles complying with United States ANSI Z87.1 (shown on

package) before commencing power tool operation. Safety goggles are available through your Sears catalog.

Check for shipping damage. If damage has occurred, a claim must be filed with carrier. Check for complete- ness. Immediately report missing parts to dealer.

ly on voltages not more than 10% above or below the specified voltage.

Running the unit on voltages which are not within the range may cause overheating and motor burn-out. HeaW loads require that the voltage at motor terminals be no less than the voltage specified. Power supply to the motor is controlled by a double pole locking rocker switch. Remove the key to prevent unauthorized use.

GROUNDING INSTRUCTIONS

WARNING: Improper connection of equipment grounding conductor can result in the risk of electrical shock. Equipment should be grounded while in use to protect operator from electrical shock.

Check with a qualified electrician if grounding instruc- tions are not understood or if in doubt as to whether the

tool is properly grounded. This tool is equipped with an approved 3 conductor

cord rated at 150V and a three prong grounding type plug for your protection against shock hazards.

Grounding plug should be plugged directly into a prop- erly installed and grounded 3-prong grounding-type receptacle, as shown (Figure 2).

Properly Grounded Outlet

Grounding Prong

3-Prong

Figure 2 =3=Prong Receptacle

Do not remove or alter grounding prong in any manner. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electrical shock.

WARNING: Do not permit fingers to touch the termi- nals of plug when installing or removing from outlet.

Plug must be plugged into matching outlet that is prop- erly installed and grounded in accordance with all local codes and ordinances. Do not modify plug provided. If it will not fit in outlet, have proper outlet installed by a qualified electrician.

Inspect tool cords periodically, and if damaged, have them repaired by an authorized service facility.

Green (or green and yellow) conductor in cord is the grounding wire. If repair or replacement of the electric cord or plug is necessary, do not connect the green (or green and yellow) wire to a live terminal.

Where a 2-prong wall receptacle is encountered, it must be replaced with a properly grounded 3-prong receptacle installed in accordance with National Electric

Code and local codes and ordinances. WARNING: This work should be performed by a quali-

fied electrician. A temporary 3-prong to 2-prong grounding adapter (see

Figure 3) is available for connecting plugs to a two pole outlet if it is properly grounded.

Do not use a 3-prong to 2-prong grounding adapter unless permitted by local and national codes and ordi- nances. (A 3-prong to 2-prong grounding adapter is not permitted in Canada.) Where permitted, the rigid green

tab or terminal on the side of the adapter must be

securely connected to a permanent electrical ground such as a properly grounded water pipe, a properly grounded outlet box or a properly grounded wire system.

Many cover plate screws, water pipes and outlet boxes are not properly grounded. To ensure proper ground, grounding means must be tested by a qualified electri-

cian.

EXTENSION CORDS

• The use of any extension cord will cause some drop in voltage and loss of power.

• Wires of the extension cord must be of sufficient size

to carry the current and maintain adequate voltage.

• Use the table to determine the minimum wire size (A.W.G.) extension cord.

Use only 3-wire extension cords having 3-prong grounding type plugs and 3-pole receptacles which accept the tool plug.

If the extension cord is worn, cut or damaged in any way, replace immediately.

+ Check to make sure blade is tensioned and tracking

properly. Do not over tension the blade in order to prevent premature blade wear and breakage. Avoid under tensioning to eliminate back and forth, side to

side blade movement as it cuts.

+ Use proper blade for the cutting operation. + After turning saw on, allow blade to come to full

speed before attempting any cutting operation.

+ Support workpiece firmly against table and use a

smooth steady feed to guide work through the cut. Use push sticks or push blocks when required.

+ Keep hands away and out of line with moving parts. + Always wear eye protection.

+ Do not remove jammed cutoff pieces until blade has

stopped.

INSTALLING BLADE

• Although most of the adjustments are not changed when blade is removed, every adjustment should be

checked prior to using a newly installed blade.

• Make sure blade teeth are pointing down towards

table. Turn blade inside out if necessary.

• Slip new blade into table slot and over the upper and lower blade wheels. Slide blade in between blade

guards.

• Tension blade by turning blade tensioning lever clockwise, as far as it will go (see Figure 5). This is a spring loaded, tensioning mechanism and it will automatically apply required tension to the blade.

• Use the tension knob to make fine adjustments to blade tension

Close the doors and fasten latches.

NOTE: When closing doors, make sure that the edges of the doors and frame are firmly fitted together before attempting to secure door. This is necessary for proper

operation of dust collection system. The latches will not pull the doors and frame together.

• Install table insert. Track blade as described in the following sections.

TRACKING BLADE

Refer to Figures 5 and 11. WARNING: Be very careful; improperly tracked blade

may spring out from wheels causing serious injury. Do not perform tracking adjustment while band saw is

running.

• Disconnect band saw from power source.

• To check the blade tracking, rotate drive wheel by hand in clockwise direction. View blade through

tracking window.

Proper tracking is achieved when drive and idler wheels are aligned. Tracking knob (Key No. 11) on

the back of the tool frame is used to tilt upper wheel

and align blade wheels. If blade rides away from cabinet, turn knob

clockwise. If blade rides toward cabinet, turn knob counterclockwise.

BLADE GUIDES

NOTE: Adjust blade guides only after blade has been properly tensioned and tracked.

• Blade guides support blade at sides and rear of blade, and prevent twisting or deflection.

Blade guides should not touch blade when no work- piece is in contact with blade. Adjust guides as described in following section.

UPPER BLADE GUIDES

= Upper blade guides employ guide pins for side

support and a ball bearing for rear support. Loosen screws and adjust guide pins to sides of the

blade (see Figure 7). Use a feeler gauge to check

that guide pins are 0.002" away from blade.

Adjust the height of upper guide to clear the work- piece by ¼". Loosen upper guide knob (Figure 10,

Key No. 25) and adjust height of upper guide until it clears workpiece by ¼".Tighten upper guide knob.

LOWER BLADE GUIDES

• Lower blade guides employ guide pins for side sup- port and bearing for rear support.

• Loosen screws (see Figure 9) and move guide pins away from blade sides.

Lock adjustment by tightening screws.

BLADE SELECTION

• Blades vary depending on type of material, size of workpiece and type of cut that is being performed.

Characteristics which make blades different are width, thickness and pitch.

BLADE WIDTH

Width of blade describes distance from tip of a tooth to back of blade.

Width of blade affects rigidity of blade. A wider blade wanders less and produces a straighter cut.

Width of blade also limits the smallest radius which can be cut. A 1A"wide blade can cut about a Y2"radius.

BLADE THICKNESS

• Blade thickness describes the distance between sides of blade. A thicker blade has more rigidity and

stronger teeth. A narrow thick blade is used to cut curves while a wide thin blade is used to make long, straight cuts.

BLADE PITCH

Pitch describes number of teeth per inch or tooth

size. A blade with more teeth per inch produces a smoother cut.

The type of material being cut determines number of teeth which should be in contact with work.

® For soft materials, the proper blade has between 6 to

8 teeth per inch. When cutting hard materials, where shocking is

more detrimental, use a blade with 8 to 12 teeth per inch.

• There should always be at least three teeth in contact with cut to avoid shocking blade.

Blade shocking occurs when pitch is too large and

blade tooth encounters too much material. This can strip teeth from blade.

• Blade manufacturers are prepared to supply

information about blades for specific applications.

Loosen socket head bolts (Figure 10, Key No. 61) and adjust lower guide bracket position so that rear

of blade is positioned 0.002" away from bearing. Tighten socket head bolts. Adjust guide pins (see Figure 9) to sides of the

blade. Use a feeler gauge to check that guide pins are 0.002" away from blade.

TYPE OF CUT

• Contour cutting is done by guiding workpiece free-handed to produce curved shapes.

• Beveled cutting is done by tilting saw table and using proper work guide method.

Regardless of which work guiding method is used, a

workpiece which overhangs table by more than 5"

needs proper support.

CONTOUR SAWING

When contour sawing, use both hands to keep work- piece flat against table and guided along desired path.

Avoid positioning hands in line with blade. If hands slip, they could contact blade.

• Try to stand to front of the saw and use hands over

the portion of table which is to right of blade and

before cut. Cut small corners by sawing around them. Saw to

remove scrap until desired shape is obtained.

BEVEL CUTTING

Refer to Figure 10.

• Perform bevel cutting by tilting table to desired degree.

• Unlock table by loosening locking handle located on

the backside of the unit (Key No. 14).

• Tilt table to desired position by rotating knob (Key No. 18).

• Lock table in position by tightening locking handle.

MITER GAUGE

= Use miter gauge for securing and holding workpiece

at desired angle to produce angled cuts. Use scale

to adjust gauge to desired angle.

WARNING: Never use miter gauge and rip fence at the same time. The blade might bind in the workpiece. Operator could be injured and/or workpiece could be damaged.

BLADE CLEANING BRUSH

Refer to Figure 10.

• Make sure that brush (Key No. 57) is in contact with blade to properly remove foreign particles from drive

wheel.

WARNING: Make certain that unit is disconnected

from power source before attempting to service or

remove any component.

CLEANING

• Keep machine and workshop clean. Do not allow sawdust to accumulate on band saw.

• Keep wheels clean. Debris on wheels will cause poor tracking and blade slippage.

• Keep mechanisms and threaded or sliding surfaces clean and free of foreign particles.

• Operate band saw with a dust collector to minimize clean up.

LUBRICATION

• The shielded ball bearings are permanently lubricat-

ed and require no further lubrication.

• Small amounts of machine oil can be applied to belt

tension mechanisms and threaded or sliding sur- faces.

• Occasionally apply a coat of paste wax to table top

to keep it slick and corrosion free.

KEEP BAND SAW IN REPAIR

• If power cord is worn or cut in any way, have it replaced.

• Replace any damaged or missing part.

• Use parts list to order parts.
