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.
Refer to Figures 6 and 7.

CAUTION: Do not operate the band saw and the
welder at the same time.
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.
• 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.
Page 7
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.
Page 8
BLADE SPEED AND BLADE PITCH CHART (FEET PER MINUTE/TEETH PER INCH)
• 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.

Page 9
ADJUSTING TABLE ANGLE
Refer to Figure 16.
Angle cuts can be made by tilting table left to right.
Loosen socket head bolts (Key No. 12) to tilt table up
to 15° right or left. Use angle scale to set table angle
(Key No. 18).
TYPE OF CUT
• Band saw can be used to perform a variety of cuts.
Cutting procedure used depends on size and
desired shape of cut.
• The rip fence is used to guide workpiece to produce
straight cuts on longer pieces.
• Contour cutting is done by guiding workpiece free
hand to produce curved shapes.
• Beveled cutting can be done with any proper work
guide method by tilting table.
• Regardless of which method is used, a workpiece
which overhangs table by more than 10" should be
properly supported by free standing material stands.
See “Recommended Accessories,” page 17.
USING RIP FENCE
Refer to Figure 16.
• Rip fence is used to guide workpiece straight into
blade producing a desired width of cut. Set rip fence
to desired width of cut on either side of blade. Kerf
of the blade must be considered when setting up.
• Lock rip fence securely with rip fence lock knob
(Key No. 43). The portion of material between blade
and rip fence is considered the workpiece. Material
outside of blade is considered scrap to be cut off.
• Guide workpiece into blade but do not push on scrap
side of material. Avoid passing hands beyond blade.
Use push sticks to finish cuts and pass workpiece
away from blade.
MITER GAUGE
• Use miter gauge (not provided) for securing and
holding workpiece at desired angle to produce
angled cuts. Use scale to adjust gauge to desired
angle.
• Never use miter gauge (not provided) and rip fence
at the same time. The blade might bind in the work
piece. Operator could be injured and/or workpiece
could be damaged.
PREPARING BLADE FOR WELDING
• A properly prepared blade is essential in producing
a high-quality, long lasting band saw blade.
• The blade must be cut to proper length.
• Blade ends should be cut and ground square.
• Any rust, oil or dirt must be removed.
• Some teeth must be ground off blade ends depending
upon the pitch of the blade.
BLADE CUTTING
Refer to Figure 9.
• Cut the blade ends flat, square and smooth using
the blade shear.
• Lean the back of blade against the shear blade
guide when cutting blade ends (See Figure 9).
• Use grinder, as needed, to make blade ends flat,
square and smooth.
CONTOUR CUTTING
• When contour cutting, both hands must be used
to keep workpiece flat against table and guided
along path.
• Avoid placing hands in line of blade. If hands contact
blade it may cause injury.
• Stand in front of saw and use both hands over
portion of table to right of blade and before cut.
Do not attempt to cut sharp corners.
• Cut small corners by sawing around them and
removing scrap until shape is produced.
CHIP BLOWER
Refer to Figure 16.
• Band saw is equipped with chip blower used to
remove chips to make contour cutting easier.
• Adjust air nozzle (Key No. 31) so that pump air
blows chips away from blade and workpiece.
Figure 9 - Blade Cutting Alignment Surface
BLADE MOUNTING
Refer to Figure 10, page 10.
• Clean welder jaw of any scale, oil, rust or dirt. Clean
blade ends which contact welder jaws to provide
proper electrical contact.
• Set weld pressure adjustment knob to “0” (released).
• Insert one end of blade into stationary jaw with teeth
facing out and blade end centered between jaws.
• Firmly set back of blade against back alignment
surface of welder jaw and clamp blade tight with
the jaw clamping handle (See Figure 10, page 10).
• Insert other end of blade into movable jaw; butt the
blade ends together and clamp tight.
IMPORTANT: The blade ends should butt against each
other over the full width of the blade and should not
overlap (See Figure 10, page 10).
Page 10
• Tooth grinding procedure must be done carefully In
order to grind the proper number of teeth and not to
grind below gullet which would weaken the blade.

BLADE WELDING
Refer to Figures 7 and 12.
• To set weld pressure adjustment knob, turn the knob
counterclockwise to Increase the pressure. The pres
sure adjustment knob controls force applied to the
movable jaw.
NOTE: Weld pressure adjustment knob must be reset
to “0” after each welding.
• Wider blades and thicker blades need more weld
pressure to force the blade ends together during
welding. If too little pressure is applied, the blade
ends will melt. Too much pressure may cause the
blades to overlap.
For example, for V2” wide blades, turn the pressure
adjustment knob counterclockwise until the pointer
is at 6 (See Figure 12).
TOOTH SPACING
Refer to Figure 11.
* Approximately Vs” of blade will be consumed during
the welding process. This blade loss must be taken
into account.
• All blades must have some of the teeth ground off so
that the tooth spacing will be uniform after welding.

Figure 12 - Weld Pressure Adjustment
• If blade melts, increase pressure. If there are “blow
holes” In the weld, increase pressure.
• If blade overlaps, decrease pressure.
• Wider blades need more pressure and thinner
blades need less pressure. Weld pressure is also
affected by blade material.
WARNING; Welding operation produces sparks at
blade intersection. Step away to left side of welder
during welding operation.
WARNING: Always wear ANSI approved safety
glasses during welding. Sparks from welder can
cause serious injury to eyes.
• Press weld button and hold down. The blade ends
will become red hot and soft. The movable jaw will
force the blade ends together creating a bead of
metal and the limit switch will automatically cut
power to jaws.
• Release weld button and wait 10 seconds to allow
blade to cool.
• Reset weld pressure adjustment to “0”.

Page 11
• Heat build-up in the tool can cause serious damage
to the tool. Allow transformer to cool down to room
temperature between each welding or each anneal
ing operation. It Is a safe procedure to let the trans
former be Idle for at least 3 minutes between
successive welding/annealing operations.
MAINTENANCE
WARNING: Make certain that unit is disconnected
from power source before attempting to service or
remove any component.
BLADE ANNEALING
• After the blade has been welded, the weld area will
be very hard and brittle. Before the blade can be
used, it must be annealed and the flash removed.
• The blade weld is annealed by heating the blade
just under the melting temperature and then slowly
cooling the weld.
NOTE: Reset weld pressure adjustment knob to “0”
prior to annealing. Failure to do so can cause damage
to transformer.
• Press the anneal button until the weld area glows
a cherry red and then release the anneal button.
CAUTION: The blade weld will melt, destroying the
weld, if the anneal button is not released as soon as
the weld glows cherry red.
• Let the blade cool for several seconds.
• Press the anneal button again, but release the but
ton before the weld glows as brightly as the first
time.
• Wait several seconds until the blade cools further.
• Repeat the anneal process 6 or 7 times, decreasing
the anneal temperature each time.
• The weld flash must be ground from the blade. See
“Grinding Blade”.
GRINDING BLADE
• After annealing the blade, the metal buildup or flash
must be ground from the blade.
• Toggle grinder switch to the ON position.
• Flip the grinder guard open, exposing the top of the
grinding wheel.
• Weld should be ground to same thickness as blade.
• Grind flash off underside of blade taking care not
to grind into blade.
• Turn blade inside out and grind other side of blade
same as first side (or, flip the grinder guard to the
closed position and use the bottom of the wheel).
• Take care not to grind into blade.
• Turn blade inside out again (to original shape).
• Turn grinder off when grinding is completed. The
blade must be annealed again.
ANNEAL BLADE AFTER GRINDING
• After flash has been removed, anneal the blade a
second time. The weld may have been hardened
by heat created during grinding. Repeat “Blade
Annealing” step.
• After second blade annealing operation, the blade
is ready for installation onto band saw. Follow band
saw instruction when installing and adjusting blade.
CLEANING
Refer to Figure 15.
• 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.
• Make sure that brush (Key No. 63) is in contact with
blade to properly remove foreign particles from
drive wheel.
LUBRICATION
Refer to Figures 15-17.
• The shielded ball bearings are permanently lubricat
ed and require no further lubrication.
• Grease guide post (Figure 16, Key No. 36) once a
week. Grease speed operator shaft in gearbox hous
ing (Figure 15, Key No. 28 and 45) and blade tension
lead screw (Figure 15, Key No. 16) every 100 hours.
Use grease gun on grease fitting every 100 hours
(Figure 17, Key No. 10). Grease table support
