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.

BE PREPARED FOR JOB

• Wear proper apparel. Do not wear loose clothing, gloves, neckties, rings, bracelets or other jewelry

which may get caught in moving parts of machine.

• Wear protective hair covering to contain long hair.

• Wear safety shoes with non-slip soles.

• Wear safety glasses complying with United States

ANSI Z87.1. Everyday glasses have only impact

resistant lenses. They are NOT safety glasses.

• 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.

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 it was 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 recommended accessories (refer to page 15). Use of improper accessories may cause 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. The scroll saw comes assembled as one unit.

Additional parts which need to be fastened to the saw should be located and accounted for before assem-

POWER SOURCE

The motor is designed for operation on the voltage and

frequency specified. Normal loads will be handled safe- 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. Heavy loads require that the voltage at motor terminals

be no less than the voltage specified. Power supply to the motor is controlled by a single 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.

3-Prong Plug__

Figure 5 - 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 6) is available for connecting plugs to a two pole outlet if it is properly grounded.

• 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 will affect rigidity of blade. A wider

blade will wander less and produce a straighter cut.

• Width of blade also limits the smallest radius which can

be cut. A IA" wide blade can cut about a ½" radius.

BLADE THICKNESS

• Blade thickness describes the distance between

sides of blade. A thicker blade has more rigidity and stronger teeth.

BLADE PITCH

• Pitch describes number of teeth per inch or tooth

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

• Use a finer (more teeth/inch) blade for thin work-

pieces and hard materials.

• Use a coarser (less teeth/inch) blade for thick work-

pieces and softer materials.

• There should always be at least two teeth in

contact with workpiece.

• Blade manufacturers are prepared to supply

information about blades for specific applications.

Figure 17 - upper Blade Holder

• Release blade lock/release lever.

• Replace table insert.

FEED RATES

• Feeding at a slower rate produces a better surface finish.

• Do not try to feed workpiece faster than the blade

can cut. This will cause blade breakage.

BLADE SPEEDS

• Most workpieces (hardwood and softwood thicker

than '/4") can be cut with speeds of 1000 to 1400 strokes/minute.

• Begin at a slower speed and gradually increase the

speed to the above mentioned range.

• Use slower speeds for thin workpieces, intricate cuts

and when using thin blades.

BLADE SELECTION

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

TYPE OF CUT

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

• Beveled cutting can be done by tilting saw arm and

using proper work guide method.

• Regardless of which work guiding method is used, a workpiece which overhangs table by more than 5"

should be properly supported

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.

• Cut small corners by sawing around them. Saw to

remove scrap until desired shape is obtained.

BEVEL CUTTING

Refer to Figures 12 and 13, page 7.

• Perform bevel cutting by tilting head to desired

degree.

• Unlock head by loosening locking handle located on

the backside of the unit.

• Tilt head to desired position.

• Lock head in position by tightening locking handle.

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 scroll saw.

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

LUBRICATION

• The shielded ball bearings are permanently lubricat- ed and require no further lubrication.

• Small amounts of machine oil can be applied to belt pulley mechanism and threaded or sliding surfaces.

• Occasionally apply a coat of paste wax to table top to keep it slick and corrosion free.

KEEP SCROLL SAW IN REPAIR
