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.
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.
2
• 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 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 gog-
gles complying with United States ANSI Z87.1 (shown
on package) before commencing power tool operation.

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.
• Always wear eye protection.
REMOVING BLADE
Refer to Figures 7 and 9.
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.
• Loosen hex nut (Figure 7, Key No. 30) and rotate
handwheel (Figure 7, Key No. 23) to release blade
tension. Be careful; blade may spring from saw when
tension is released. Remove table stud (Figure 9,
Key No. 15), take out the released blade and replace
with another blade.
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.
• Tension and track blade as described in the following
sections.
TENSIONING BLADE
Refer to Figure 7.
• Tension blade by rotating handwheel (Key No. 23). 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 7.
• Track blade after it has been tensioned. A change in
blade tension will affect wheel alignment.
• Proper tracking is achieved when drive and idler
wheels are aligned. Knob (Key No. 29) is used to tilt
tracking bar (Key No. 13) and align blade wheels.
• Loosen nut (Key No. 30) which locks tracking knob
(Key No. 29). Turn idler wheel (Key No. 7) by hand
and observe how blade rides on wheels.
• If blade rides away from cabinet, turn knob clockwise
to tilt idler wheel up.
• If blade rides into cabinet, turn tracking knob coun-
terclockwise.
6
• When blade is tracking properly, lock position by
holding knob and tightening nut (Key No. 30) against
the cabinet.
ALIGNMENT OF DRIVE WHEEL
Refer to Figure 10.
NOTE: Only attempt adjusting drive wheel alignment if
blade cannot be properly tracked with tracking adjust-
ment alone.
• A blade under high tension may also pull drive wheel
out of alignment.
• Adjust alignment of drive wheel with hex head bolts
(Key Nos. 8 and 30).
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 sections.
UPPER BLADE GUIDES
Refer to Figure 8.
• Upper blade guides employ guide pins for side sup-
port and a ball bearing on an adjusting pin at rear.
• Upper guide bracket (Key No. 13) should be posi-
tioned so guide on either side of blade will support
as much of blade width as possible without interfer-
ing with the tooth set.
• Adjust bracket depth by loosening bolts (Key Nos. 9
and 12) and sliding brackets into position. Secure
position of upper guide casting by tightening bolts.
• Loosen set screws (Key No. 15) and adjust guide
pins (Key No. 14) to side of blade. Use a feeler
gauge to check that guide pins are .002" away from
blade.
• Lock adjustment by tightening set screws.
• Adjust thrust bearing (Key No. 17) at rear of blade by
loosening set screw (Key No. 15).
• Position thrust bearing (Key No. 17) .002" away from
back of blade.
• Secure position of thrust bearing by tightening set
screw.
• Adjust the height of upper guide casting to clear the
workpiece by W'. Loosen knob (Key No. 30) and
rotate height adjustment knob (Key No. 22) until
upper blade guide bracket clears workpiece by W'.
Tighten knob (Key No. 30).
LOWER BLADE GUIDES
Refer to Figure 8.
• Lower blade guides employ two guide blocks for side
support. Lower guide bracket (Key No. 33) is spaced
close to table surface to minimize unsupported
length of blade.
• Loosen bolt (Key No. 19) to position lower guide
bracket on alignment block (Key No. 31). Adjust
lower guide bracket so guide blocks do not interfere
with blade set. Loosen set screws (Key No. 23) for
guide blocks (Key Nos. 21 and 34) and adjust guide
blocks to .002" from each side of blade.
• Adjust thrust bearing (Key No. 36) at rear of blade by
loosening set screw (Key No. 23). Position thrust
bearing .002" away from back of blade. Secure posi-
tion of thrust bearing by tightening set screw.
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 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 W' wide blade can cut about a W'
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 would be used to cut curves
while a wide thin blade would be 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 will produce 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
and 12 teeth per inch.
• When cutting hard materials, where shocking is more
detrimental, use a blade with 12 to 24 teeth per inch.
• There should always be at least three teeth in con-
tact 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 informa-
tion about blades for specific applications.
BLADE SPEED
•The amount of force with which the blade cuts is
determined by speed.
• High cutting speeds are used on soft materials
where less force is needed and a high rate of materi-
al removal is desired.
• Low cutting speeds are used on hard materials
when more force is required.
• To change blade speed, position V-belt in proper
configuration (see Figure 5). Reposition and tension
V-belt as described in the next section.

Figure 5 - Blade Speeds
REPOSITIONING V-BELT
Refer to Figures 5, 6 and 10.
• Blade speed is determined by the position of the
V-belt on the idler and motor pulleys (Figure 10, Key
Nos. 23 and 26). Blade speed is changed by chang-
ing pulley position of V-belt.
• Be sure to disconnect saw from power and turn saw
OFF before attempting to change blade speed.
• To change blade speed loosen motor mount plate
(Figure 6, Key No. 9) by loosening hex nut on hex
head bolt (Figure 6, Key Nos. 14 and 11). Position V-
belt on motor and idler pulleys as required. See
Figure 5, Blade Speeds, for recommended pulley
and belt settings.
• Tension V-belt by pushing down on motor mount
plate and tightening nut on the hex head bolt. Be
sure nut and bolt are tight. Belt is properly tensioned
when light pressure applied to midpoint of the belt
produces about 1/2"deflection. Do not over tighten
V-belt.
TYPE OF CUT
• Rip fence guides workpiece to produce straight cuts
on longer pieces.
• Contour cutting is done by guiding workpiece free-
handed to produce curved shapes.
• Beveled cutting can be done by tilting table and
using proper work guide method.
• Regardless of which work guiding method is used, a
workpiece which overhangs table by more than 7"
should be properly supported by support stands.
(See Recommended Accessories, page 15.)
RIP FENCE OPERATION
Refer to Figure 9.
• Rip fence can be used to guide boards with one
square edge past blade when table is aligned prop-
erly.
• Set rip fence to desired width of cut on inside of
throat. Remember to include the thickness of materi-
al that will be removed by blade.
• Use a square to measure from tip of a tooth to
fence. Lock fence securely with knob (Key No. 6).
• The portion of material between blade and fence is
considered the workpiece. Material on outside and
behind cut is the scrap material which is being cut
off. Use the right hand to keep work against fence.
• Do not push on scrap portion of the work. This could
pinch or bind blade.
• Avoid passing hands beyond the cut. Use push
sticks or push blocks to finish cuts and pass work-
piece away from blade.
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 9.
• Perform a bevel operation by tilting table. Loosen
knob (Key No. 11) and tilt table to desired position.
• Use a square or protractor to set angle and lock
table in position with knob. Use caution when sup-
porting work while bevel cutting. Do not allow work
to hang on blade.
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.
• 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 7.
•Make sure that brush (Key No. 36) is in contact with
wheel 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-
