INTRODUCTION
About This Machine
Capabilities
Features
This 14" Metal-Cutting Bandsaw allows you to
make exterior and interior contoured or straight
cuts. To better understand these capabilities,
imagine making a "doughnut" out of 1" steel
plate.
Now that you know the basics of what this
machine can do, take a minute to consider its
features.
This machine is equipped with a built-in air
blower near the blade guides. This feature keeps
metal chips away from the cutting area, so you
can accurately follow pre-drawn cutting lines
without metal chips getting in the way.
The outside circular shape can be easily cut by
moving the workpiece around the blade, using a
pre-drawn line as a cutting guide.
Cutting the inside hole would normally be a
difficult task with a bandsaw. But this machine
makes it easy. First, the bandsaw blade is cut
with the built-in blade shear. A hole slightly
larger than the blade is then drilled into the
center of the workpiece, so the blade can be
threaded through the hole. The ends of the blade
An adjustable work lamp is also provided above
the table to eliminate shadows from the work
area. This is a great feature when doing close up
work near moving blades!
We also equipped this bandsaw with variable
speed, so you can precisely control cutting
are then clamped into the built-in welder, welded results for the type of blade installed and type
back together, annealed, and ground flat with the of material being cut. This is a great feature to
built-in grinder. Once the blade is re-installed on
the wheels, it can then be used to cut the interior
hole and complete the doughnut shape. After
completion, the blade is sheared again to remove
it from the workpiece.
have when doing precision cutting.
Aside from features, we designed this machine to
be extremely solid and durable. We used heavy
gauge steel for the wheel doors, ridiculously thick
table trunnions and frame castings, USA-made
Allen-Bradley electronics, and Japanese-made
NSK ball bearings.
Aside from the above capabilities, this machine
can also be used for straight cuts in sheets too
large to fit in the vise of a horizontal metal-
cutting bandsaw
For example, if you needed to cut a 24" x
24" sheet of 1" steel in half, you can clamp a
straightedge to the bandsaw table, then guide
the sheet along the straightedge to make a nice
straight cut. Cutting this same size of stock on a
horizontal bandsaw would require a very large
machine.
On the other hand, if you need to "resaw" an 8"
x 8" billet into a series of 1" thick plates, clamp
a straightedge 1" away from the blade, raise the
blade guides to accommodate the height of the
billet, and each cut you make will produce an 8"
x 1" plate.
Both of these types of straight cuts can also be
made with the table tilted to 15°, which creates a
beveled cut.

SAFETY
Understanding Risks of Machinery
Operating all machinery and machining equipment can be dangerous or relatively safe depending
on how it is installed and maintained, and the operator's experience, common sense, risk awareness,
working conditions, and use of personal protective equipment (safety glasses, respirators, etc.).
The owner of this machinery or equipment is ultimately responsible for its safe use. This
responsibility includes proper installation in a safe environment, personnel training and usage
authorization, regular inspection and maintenance, manual availability and comprehension,
application of safety devices, integrity of cutting tools or accessories, and the usage of approved
personal protective equipment by all operators and bystanders.
The manufacturer of this machinery or equipment will not be held liable for injury or property
damage from negligence, improper training, machine modifications, or misuse. Failure to read,
understand, and follow the manual and safety labels may result in serious personal injury, including
amputation, broken bones, electrocution, or death.
The signals used in this manual to identify hazard levels are defined as follows:
Death or catastrophic
harm WILL occur.
Moderate injury or fire
MAY occur.
Death or catastrophic
harm COULD occur.
Machine or property
damage may occur.

1. Owner’s Manual: All machinery and
machining equipment presents serious
injury hazards to untrained users. To
reduce the risk of injury, anyone who uses
THIS item MUST read and understand
this entire manual before starting.
3. Trained/Supervised Operators Only:
Untrained users can seriously injure
themselves or bystanders. Only allow
trained and properly supervised personnel
to operate this item. Make sure safe
operation instructions are clearly
understood. If electrically powered, use
padlocks and master switches, and remove
start switch keys to prevent unauthorized
use or accidental starting.
2. Personal Protective Equipment: Operating
or servicing this item may expose the user
to flying debris, dust, smoke, dangerous
chemicals, or loud noises. These hazards
can result in eye injury, blindness, long-
term respiratory damage, poisoning,
4. Guards/Covers: Accidental contact with
moving parts during operation may cause
severe entanglement, impact, cutting,
or crushing injuries. Reduce this risk by
keeping any included guards/covers/doors
installed, fully functional, and positioned
for maximum protection.
cancer, reproductive harm or hearing loss.
Reduce your risks from these hazards
by wearing approved eye protection,
respirator, gloves, or hearing protection.

Model SB1021/SB1022
S A F E T Y
5. Entanglement: Loose clothing, gloves,
neckties, jewelry or long hair may
get caught in moving parts, causing
entanglement, amputation, crushing,
or strangulation. Reduce this risk by
removing/securing these items so they
cannot contact moving parts.
11. Chuck Keys or Adjusting Tools: Tools used
to adjust spindles, chucks, or any moving/
rotating parts will become dangerous
projectiles if left in place when the machine
is started. Reduce this risk by developing
the habit of always removing these tools
immediately after using them.
12. Work Area: Clutter and dark shadows
increase the risks of accidental injury.
Only operate this item in a clean, non-
glaring, and well-lighted work area.
6. Mental Alertness: Operating this item
with reduced mental alertness increases
the risk of accidental injury. Do not let a
temporary influence or distraction lead to a
permanent disability! Never operate when
under the influence of drugs/alcohol, when
tired, or otherwise distracted.
13. Properly Functioning Equipment: Poorly
maintained, damaged, or malfunctioning
equipment has higher risks of causing
serious personal injury compared to
those that are properly maintained.
To reduce this risk, always maintain
this item to the highest standards and
promptly repair/service a damaged or
malfunctioning component. Always follow
the maintenance instructions included in
this documentation.
7. Safe Environment: Operating electrically
powered equipment in a wet environment
may result in electrocution; operating near
highly flammable materials may result in a
fire or explosion. Only operate this item in
a dry location that is free from flammable
materials.
8. Electrical Connection: With electically
powered equipment, improper connections
to the power source may result in
14. Unattended Operation: Electrically
powered equipment that is left unattended
while running cannot be controlled and is
dangerous to bystanders. Always turn the
power OFF before walking away.
electrocution or fire. Always adhere to all
electrical requirements and applicable
codes when connecting to the power source.
Have all work inspected by a qualified
electrician to minimize risk.
15. Health Hazards: Certain cutting fluids
and lubricants, or dust/smoke created
when cutting, may contain chemicals
known to the State of California to cause
cancer, respiratory problems, birth defects,
or other reproductive harm. Minimize
exposure to these chemicals by wearing
approved personal protective equipment
and operating in a well ventilated area.
9. Disconnect Power: Adjusting or servicing
electrically powered equipment while it
is connected to the power source greatly
increases the risk of injury from accidental
startup. Always disconnect power
BEFORE any service or adjustments,
including changing blades or other tooling.
16. Difficult Operations: Attempting
difficult operations with which you are
unfamiliar increases the risk of injury.
If you experience difficulties performing
the intended operation, STOP! Seek an
alternative method to accomplish the
same task, ask a qualified expert how the
operation should be performed, or contact
our Technical Support for assistance.
10. Secure Workpiece/Tooling: Loose
workpieces, cutting tools, or rotating
spindles can become dangerous projectiles
if not secured or if they hit another object
during operation. Reduce the risk of this
hazard by verifying that all fastening
devices are properly secured and items
attached to spindles have enough clearance
to safely rotate.

Additional Metal Cutting Bandsaw Safety
1. Blade Condition: Do not operate with a
dull, cracked or badly worn blade—they can
break during use or greatly decrease cutting
performance. Inspect blades for cracks and
missing teeth before each use.
7. Magnesium Fire Hazard: Use EXTREME
CAUTION if cutting magnesium. Using
the wrong cutting fluid or overheating the
material could lead to an extremely hot fire
that is difficult to extinguish. Additionally,
do not allow magnesium swarf or dust to pile
up around the machine and only dispose of
the waste using approved methods.
2. Blade Replacement: Wear gloves to protect
hands and safety glasses to protect eyes
when replacing the blade. When replacing
blades, make sure teeth face forward and
down toward the table in the direction of
blade travel.
8. Entanglement Hazards: Always keep the
blade guard correctly positioned and wheel
doors closed and secured when bandsaw is in
operation. Loose clothing, jewelry, long hair
and work gloves can be drawn into working
parts.
3. Workpiece Handling: Your hands can be cut
or drawn into the blade during operation if
the workpiece moves unexpectedly. Always
keep your hands a safe distance away from
the moving blade.
9. Maintenance/Service: All inspections,
adjustments, and maintenance are to be
done with the power OFF and the plug
pulled from the outlet. Wait for all moving
parts to come to a complete stop.
4. Welding And Grinding Safety: The welding
station can be hazardous if used incorrectly
and without proper personal protection.
Always wear welding-approved gloves,
eye protection, and clothing when welding
blades. Touching any metal parts of the
blade, welder, or machine when activating
the welder could lead to electrocution.
10. Unstable Workpieces: Workpieces that
cannot be supported or stabilized without
a vise or jig should not be cut on a vertical
metal-cutting bandsaw, because they can
unexpectedly move while cutting and
Welding near flammables could cause a fire.
draw the operator's hands into the blade
causing serious personal injury. Examples
are chains, cables, round or oblong-shaped
workpieces, workpieces with internal or
built-in moving or rotations parts, etc.
5. Hot Surfaces: Be aware that touching hot
workpieces or chips after welding, grinding,
or cutting can cause burns.
11. Clearing Chips: Metal chips can easily cut
skin—even through a piece of cloth. Avoid
clearing chips by hand or with a rag. Use a
brush or vacuum to clear metal chips.
6. Cutting Fluid Safety: This machine is
designed for dry cutting operations. Flood-
type cutting fluid setups should not be used
because the machine is not waterproof.

The benefit of this rust preventative is that it
works very well. The downside is that it can be
time-consuming to thoroughly remove.
Many cleaning solvents are
toxic if inhaled. Minimize
your risk by only using
these products in a well
ventilated area.
Be patient and do a careful job when cleaning
and removing the rust preventative. The time
you spend doing this will reward you with
smooth-sliding parts and a better appreciation
for the proper care of the unpainted surfaces.
Avoid chlorine-based solvents, such as
acetone or brake parts cleaner that may
damage painted surfaces. Always follow the
manufacturer’s instructions when using any
type of cleaning product.
Although there are many ways to successfully
remove the rust preventative, we have cleaned
thousands of machines and found the following
process to be the best balance between efficiency
and minimized exposure to toxic fumes or
chemicals.
Basic steps for removing rust preventative:
1. Put on safety glasses and disposable gloves.
2. #OAT ALL SURFACES THAT HAVE RUST PREVENTATIVE
with a liberal amount of your cleaner or
degreaser and let them soak for a few
minutes.
Before cleaning, gather the following:
s
s
$ISPOSABLE rags
#LEANERꢀDEGREASER (certain citrus-based
degreasers work extremely well and they
have non-toxic fumes)
3. Wipe off the surfaces. If your cleaner or
degreaser is effective, the rust preventative
will wipe off easily.
s
3AFETY GLASSES ꢁ DISPOSABLE GLOVES
Note: To clean off thick coats of rust preventative
on flat surfaces, such as beds or tables, use
A 0,!34)# PAINT SCRAPER TO SCRAPE OFF THE
majority of the coating before wiping it off
WITH YOUR RAGꢄ ꢅ$O NOT USE A METAL SCRAPER OR
it may scratch the surface.)
Note: Automotive degreasers, mineral spirits, or
7$sꢂꢃ CAN BE USED TO REMOVE RUST PREVENTATIVEꢄ
Before using these products, though, test them
on an inconspicuous area of a painted area to
make sure they will not damage it.
4. Repeat Steps 2–3 as necessary until clean,
then coat all unpainted surfaces with a
quality metal protectant or light oil to
prevent rust.
Gasoline and petroleum
products have low flash
points and can explode
or cause fire if used for
cleaning. Avoid using these
products to remove rust

Weight Load
Location
Refer to the Machine Specifications for the
weight of your machine. Make sure that the
surface upon which the machine is placed will
bear the weight of the machine, additional
equipment that may be installed on the machine,
and the heaviest workpiece that will be used.
Additionally, consider the weight of the operator
and any dynamic loading that may occur when
operating the machine.
Physical Environment
The physical environment where your machine
is operated is important for safe operation and
longevity of parts. For best results, operate this
machine in a dry environment that is free from
excessive moisture, hazardous or flammable
chemicals, airborne abrasives, or extreme
conditions. Extreme conditions for this type
of machinery are generally those where the
ambient temperature is outside the range of 41°–
104°F; the relative humidity is outside the range
of 20–95% (non-condensing); or the environment
is subject to vibration, shocks, or bumps.
Space Allocation
Consider the largest size of workpiece that will
be processed through this machine and provide
enough space around the machine for adequate
operator material handling or the installation
of auxiliary equipment. With permanent
installations, leave enough space around
the machine to open or remove doors/covers
as required by the maintenance and service
described in this manual.
Electrical Installation
Place this machine near an existing power
source. Make sure all power cords are protected
from traffic, material handling, moisture,
chemicals, or other hazards. Make sure to leave
access to a means of disconnecting the power
source or engaging a lockout/tagout device.
Children or untrained
people may be seriously
injured by this machine.
Only install in an access
restricted location.
Lighting
Lighting around the machine must be adequate
enough that operations can be performed
safely. Shadows, glare, or strobe effects that
may distract or impede the operator must be
eliminated.

Lifting & Moving
Leveling & Mounting
Generally, you can either bolt your machine
to the floor or mount it on machine mounts.
Although not required, we recommend that you
secure the machine to the floor and level it while
doing so. Because this is an optional step and
floor materials may vary, hardware for securing
the machine to the floor is not included.
This machine and its
parts are heavy! Serious
personal injury may occur
if safe moving methods are
not used. To reduce the
risk of a lifting or dropping
injury, ask others for help
and use power equipment.
We strongly recommend securing your
machine to the floor if it is hardwired to the
power source. Consult with your electrician to
ensure compliance with local codes.
Use a forklift to lift the machine off the pallet
and onto a suitable location using the lifting eye
shown in Figure 2.
Leveling
Leveling machinery helps precision components,
such as bed ways, remain straight and flat
during the lifespan of the machine. Components
on an unleveled machine may slowly twist due to
the dynamic loads placed on the machine during
operation.
For best results, use a precision level that
is at least 12" long and sensitive enough to
show a distinct movement when a 0.003" shim
(approximately the thickness of one sheet of
standard newspaper) is placed under one end of
the level.
Figure 2. Lifting location.
See the figure below for an example of a high
precision level.

Bolting to Concrete Floors
Assembly
Lag screws and anchors, or anchor studs
(below), are two popular methods for securing
machinery to a concrete floor. We suggest you
research the many options and methods for
securing your machine and choose the best one
for your specific application.
This machine comes pre-assembled from the
factory. However, tension has been removed from
the blade for shipping purposes. Before operating
the machine for the first time, you MUST make
sure the blade is properly tensioned. Refer to the
Blade Tensioning procedure on Page 23 for
instructions about how to do this.
Anchor
Stud
Initial Lubrication
Your machine was lubricated at the factory,
but we strongly recommend that you inspect all
lubrication points yourself and provide additional
lubrication if necessary. Refer to Lubrication on
Page 33 for specific details.

Inspections &
Adjustments
Machine Mounts
Machine mounts are rubber pads mounted to
a threaded stud, which can be fastened to the
bottom of the machine.
The following list of adjustments were performed
at the factory before your machine was shipped:
Machine mounts offer certain advantages such
as ease of installation, vibration dampening, and
easy leveling. They also make it easier to relocate
the machine later on.

Guide Post Alignment ...................Page 36
The disadvantage of machine mounts is that the
machine can shift or move over time. For this
reason, electrical codes may limit their use if
the machine is hardwired to the power source.
Also, mounts may reduce the total surface area
of machine-to-floor contact, depending on the
design of the machine.
Be aware that machine components can shift
during the shipping process. Pay careful
attention to these adjustments as you test run
your machine. If you find that the adjustments
are not set according to the procedures in this
manual or your personal preferences, re-adjust
them.

Blade Breakage
Blade Care & Break-In
Many conditions may cause a bandsaw blade to
break. Blade breakage is unavoidable, in some
cases, since it is the natural result of the peculiar
stresses that bandsaw blades must endure. Blade
breakage is also due to avoidable circumstances.
Avoidable blade breakage is most often the
result of poor care or judgment on the part of the
operator when mounting or adjusting the blade
or support guides.
Blade Care
A bandsaw blade is a delicate piece of steel that
is subjected to tremendous strain. A bandsaw
blade will last longer if you give it fair treatment
and always use the appropriate feed rate for your
operation.
Be sure to select blades with the proper width,
set, type, and pitch for each application. The
wrong blade will produce unnecessary heat and
have a shortened life.
The most common causes of blade breakage
are:
A clean blade will perform much better than
a dirty blade. Dirty or gummed up blades
pass through the cutting material with much
more resistance than clean blades. This extra
resistance also causes unnecessary heat.

Faulty alignment or adjustment of the blade
guides.

tight radius.

Feeding the workpiece too fast.
Dull or damaged teeth.
Over-tensioned blade.
The tips and edges of a new blade are extremely
sharp. Cutting at too fast of a feed rate can
fracture these tips and edges, causing the blade
to quickly become dull. Properly breaking-in a
blade allows these sharp edges to wear properly
without fracturing, thus keeping the blade sharp
longer.

Positioning Guide Post Adjusting Blade
The guide post assembly is used for two
purposes: 1) To properly position the blade guard
to protect the operator from the exposed blade
between the workpiece and the upper wheel
housing, and 2) to position the upper blade
guides close to the workpiece for maximum blade
support.
Guides
The blade guides provide side-to-side and
rear support to keep the blade straight while
cutting. The blade guides and the rear support
have tungsten steel facing to reduce wear on
the guides. Properly adjusted blade guides are
essential to making accurate cuts.
To properly position the guide post:
If the blade guides rub the blade at either the
top or bottom of the blade, follow the guide post
alignment procedure on Page 36 for adjusting
the guide post parallel with the blade.
1. DISCONNECT BANDSAW FROM POWER!
2. Hold the guide post knob with one hand and

Light generated during the welding process

Note: The welding operation leaves the blade
joint brittle. Annealing allows the material
to cool in gradual manner, giving the weld
strength and flexibility. When annealing, the
blade is heated until it turns a specific color
that is determined by the blade material.
The annealing process is unsuccessful (blade
breaks easily) if the weld is not heated
enough or if it is heated too much. For best
results, contact the blade manufacturer for
the proper annealing color.
Burning sparks may be thrown in all

Electrical Safety Instructions
These pages are accurate at the time of printing. In the constant effort to improve, however, we may
make changes to the electrical systems of future machines. Study this section carefully. If you see
differences between your machine and what is shown in this section, call Technical Support at (360)
734-1540 for assistance BEFORE making any changes to the wiring on your machine.
1. Shock Hazard: It is extremely dangerous to
perform electrical or wiring tasks while the
machine is connected to the power source.
Touching electrified parts will result in
personal injury including but not limited to
severe burns, electrocution, or death. For
your own safety, disconnect machine from
the power source before servicing electrical
components or performing any wiring tasks!
5. Circuit Requirements: Connecting the
machine to an improperly sized circuit will
greatly increase the risk of fire. To minimize
this risk, only connect the machine to a
power circuit that meets the minimum
requirements given in this manual.
6. Capacitors/Inverters: Some capacitors and
power inverters store an electrical charge for
up to 10 minutes after being disconnected
from the power source. To reduce the risk of
being shocked, wait at least this long before
working on capacitors.
2. Wire Connections: All connections must be
tight to prevent wires from loosening during
machine operation. Double-check all wires
disconnected or connected during any wiring
task to ensure tight connections.
7. Wire/Component Damage: Damaged wires
or components increase the risk of serious
personal injury, fire, or machine damage. If
you notice that any wires or components are
damaged while performing a wiring task,
replace those wires or components before
completing the task.
3. Modifications: Using aftermarket parts or
modifying the wiring beyond what is shown
in the diagram may lead to unpredictable
results, including serious injury or fire.
4. Motor Wiring: The motor wiring shown
in these diagrams is current at the time of
printing, but it may not match your machine.
Always use the wiring diagram inside the
8. Experiencing Difficulties: If you are
experiencing difficulties understanding the
information included in this section, contact
