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 operafing 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 resulf in
severe personal injury.

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 alignmenf 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 HOWTO 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.

> Sears, Roebuck and Co.

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 17).

Use of improper accessories may cause risk of
injury to persons.

Handle workpiece correctly. Protect hands from
possible 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 summed 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.

WARNING: Be careful not to touch overhead power
lines, piping, lighting, etc., if lifting equipment is used.

Band saw weighs approximately 1000 lbs. Proper tools,
equipment and qualified personnel should be employed
in all phases of unpacking and installation.

IMPORTANT: Table is coated with a protectant. To
ensure proper fit and operation, remove coating.
Coating is easily removed with mild solvents, such as
mineral spirits, and a soft cloth. Avoid getting solution
on paint or any of the rubber or plastic parts. Solvents
may deteriorate these finishes. Use soap and water
on paint, plastic or rubber components. After cleaning,
cover all exposed surfaces with a light coating of oil.

Paste wax is recommended for table top.
WARNING; Never use highly volatile solvents. Non

flammable solvents are recommended to avoid possible
fire hazard.

CAUTION; Always observe the following safety

precautions:

• Make sure that blade guides and thrust bearings are

positioned and adjusted correctly to prevent side
ways and rearward movement of the blade. Adjust
upper guide to just clear workpiece.

• 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 and speed for the cutting operation.

• After turning saw on, allow blade to come to full

speed before attempting any cutting operation.

• Support workpiece properly 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.

Figure 7 - Blade Welder Control

REMOVING BLADE

Refer to Figures 15 and 16.
WARNING; Disconnect band saw from power source

when changing or adjusting blades. Wear leather gloves
when handling band saw blades. Never wear gloves
when operating saw.

• Turn handwheel (Figure 15, Key No. 38) counter
clockwise. This lowers the idler wheel (Figure 15,
Key No. 5) and relieves tension in blade.

• Remove blade guard (Figure 16, Key No. 39) by
loosening screws (Figure 16, Key No. 49).

• Pull handle (Figure 15, Key No. 69) to open upper
and lower doors (Figure 15, Key Nos. 36 and 67).

• Be careful, blade may spring from saw.

• Remove blade from wheels and guide it out
through table slot.

INSTALLING BLADE

• Although many of the adjustments may not be altered
when blade is removed, every adjustment should be
checked prior to using a newly installed blade.

• Follow safety precautions every time saw is operated.

• Make sure blade teeth are pointing down towards
table. Turn blade inside out if necessary.

• Slip new blade into table slot and over upper and lower
blade wheels and center blade on blade wheels. Slide
blade in between blade guides. Replace table stud.
Replace blade guards after blade guide adjustment.

• Tension and track blade as described in the following
sections.

TENSIONING BLADE

Refer to Figure 15.

• Tension blade by rotating handwheel (Key No. 38). Be
sure blade guides do not interfere with blade path.

• Tighten blade until it is properly tensioned.

• A properly tensioned blade will ring slightly when back
of blade is plucked (like a string on an instrument).

NOTE: Check tension of new blade. Additional tension
may be required after a few minutes of operation.

TRACKING BLADE

Refer to Figure 15.

• Track blade after it has been tensioned. A change
in blade tension will affect wheel alignment. Proper
tracking is achieved when upper and lower wheels
are aligned.

• Set screws (Key No. 23) are used to align the track
ing bracket to the saw frame.

• Turn idler wheel (Key No. 5) by hand and observe
how blade rides on the wheels.

• If blade rides away from the cabinet, tilt wheel up by
turning knob (Key No. 30) clockwise.

• If blade rides into cabinet, tilt wheel down by turning
knob counterclockwise.

ADJUSTING BLADE GUIDES

Refer to Figures 8 and 16.

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.

• Upper blade guides employ guide blocks for side
support and a grooved bracket at rear.

• Blade guide bracket (Key No. 20) should be posi
tioned so guide blocks (Key No. 21) on either side
of blade will support as much of blade width as
possible without interfering with the tooth set.

• Adjust guide bracket depth by loosening set screw
(Key No. 40) and sliding bracket into position. Secure
position of bracket by tightening set screw.

• Loosen bolts (Key No. 24) and adjust guide blocks
(Key No. 21) to sides of blade. Use a feeler gauge to
check that guide blocks are 0.002” away from blade.

• Lock adjustment by tightening bolts.

• Adjust the height of upper guide assembly to clear
the workpiece by V4". Loosen locking knob (Key
No. 30) and use handle (Key Nos. 37 and 38) to
slide guide bar down until the upper guide assembly
clears workpiece by 77'. Tighten locking knob.

• Lower blade guides employ two guide blocks for side
support. Lower guide bracket is spaced close to table
surface to minimize unsupported length of blade.

NOTE: Lower blade guard (Key No. 56) must be
removed to adjust lower blade guides.

• Loosen bolts (Key No. 26) to adjust lower guide
bracket (Key No. 19) so guide blocks do not interfere
with blade set. Loosen socket head bolts (Key No. 24)
for guide blocks (Key No. 21) and adjust guide blocks
to 0.002" from each side of blade.

BLADE SPEED AND TYPE SELECTION

Refer to Blade Speed Chart.

• Consult Blade Speed Chart to determine blade
speed and blade type for required cutting operation.
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, type of tooth and blade pitch.

• 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 V4” wide blade can cut about a V2"
radius. Blade thickness describes the distance
between sides of blade. A thicker blade has more
rigidity and stronger teeth. A narrow thick blade
would be used to cut curves in piece while a wide
thin blade would be used to make long, straight cuts.

• Blade manufacturers are prepared to supply
information about blades for specific applications.

BLADE PITCH

Refer to Blade Speed Chart.

• Pitch describes number of teeth per inch. A blade
with more teeth per inch will produce a smoother
cut.

• Type of material being cut determines number of
teeth in contact with work.

• There should always be at least three teeth in con
tact with workpiece 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.

• When pitch is too small the gullets of the teeth will
fill up, leading to the creation of excess heat.

TYPE OF TOOTH

• The shape of teeth are varied to achieve specific
cutting results. A blade cuts work by removing
material. Blade teeth must scrape a chip of
workpiece away on each cut.

• The shape of gullet between teeth determines how
much material can be taken out with each blade
tooth.

• There should always be at least three teeth in con
tact with workpiece 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.

• When pitch is too small, gullets of teeth will fill up
leading to creation of excess heat.

• Rake angle is the angle which the cutting face of
tooth makes with a line perpendicular to the back of
blade. A 0° rake angle is used to cut hard materials.

• Positive rake angle blades are used to cut softer
materials. Softer materials require more aggressive
chip removal.

• Larger gullets provide for faster removal but have to be
limited in size because they make blade teeth weaker.

• Blade teeth will also vary in the way that teeth have
been set from one side to the other. A wider set is
used for contour work because wider kerf allows
operator to cut tighter curves.

CHANGING BLADE SPEED

Refer to Figure 15.
WARNING: Never adjust blade speed unless machine

is running or damage to saw may result.

• Blade speed is adjusted by rotating handwheel (Key
No. 50) while machine is running. Rotate handwheel
clockwise to increase blade speed. Rotate hand
wheel counterclockwise to decrease blade speed.
The blade speed is shown on LED display located
above switches.
