About This Machine

For Machines Mfg. Since 8/09

Capabilities

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.

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
are then clamped into the built-in welder, welded
back together, annealed, and ground flat with the
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.

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 metal­cutting bandsaw

Features

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.

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
results for the type of blade installed and type
of material being cut. This is a great feature to
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.

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.

For Machines Mfg. Since 8/09

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.

Death or catastrophic
harm COULD occur.

Basic Machine Safety

1. Owner’s Manual: All machinery and

chemicals, or loud noises. These hazards
can result in eye injury, blindness, long­term respiratory damage, poisoning,
cancer, reproductive harm or hearing loss.
Reduce your risks from these hazards
by wearing approved eye protection,
respirator, gloves, or hearing protection.

Operating

Moderate injury or fire
MAY occur.

Machine or property
damage may occur.

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.

4. Guards/Covers:

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.

Accidental contact with

-8-

For Machines Mfg. Since 8/09 Model SB1021/SB1022

SAFETY

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.

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.

7. Safe Environment:

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
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.

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.

Operating electrically

11. Chuck Keys or Adjusting Tools:

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:

increase the risks of accidental injury.
Only operate this item in a clean, non­glaring, and well-lighted work area.

13. Properly Functioning Equipment:

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.

14. Unattended Operation:

powered equipment that is left unattended
while running cannot be controlled and is
dangerous to bystanders. Always turn the
power OFF before walking away.

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.

Poorly

10. Secure Workpiece/Tooling:

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.

Loose

16. Difficult Operations:

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.

Additional Metal Cutting Bandsaw Safety

Blade Condition: Do not operate with a

1.

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.

Blade Replacement: Wear gloves to protect

2.

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.

Workpiece Handling: Your hands can be cut

3.

or drawn into the blade during operation if
the workpiece moves unexpectedly. Always
keep your hands a safe distance away from
the moving blade.

Welding And Grinding Safety: The welding

4.

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.
Welding near flammables could cause a fire.

Hot Surfaces: Be aware that touching hot

5.

workpieces or chips after welding, grinding,
or cutting can cause burns.

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.

Entanglement Hazards: Always keep the

8.

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.

Maintenance/Service: All inspections,

9.

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.

Unstable Workpieces: Workpieces that

10.

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
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.

Cutting Fluid Safety: This machine is

6.

designed for dry cutting operations. Flood­type cutting fluid setups should not be used
because the machine is not waterproof.

-10-

Clearing Chips: Metal chips can easily cut

11.

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.

Cleaning & Protecting

For Machines Mfg. Since 8/09

The unpainted surfaces are coated at the factory
with a heavy-duty rust preventative that
prevents corrosion during shipment and storage.
The benefit of this rust preventative is that it
works very well. The downside is that it can be
time-consuming to thoroughly remove.

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.

lthough 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.

Before cleaning, gather the following:

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.

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.

3. Wipe off the surfaces. If your cleaner or

will wipe off easily.

Many cleaning solvents are
toxic if inhaled. Minimize
your risk by only using
these products in a well
ventilated area.

Note: Automotive degreasers, mineral spirits, or

PREPARATION

Location

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.

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.

Weight Load

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.

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.

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.

PREPARATION

For Machines Mfg. Since 8/09

Lifting & Moving

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.

Use a forklift to lift the machine off the pallet
and onto a suitable location using the lifting eye
shown in Figure 2.

Leveling & Mounting

Generally, you can either bolt your machine
to the floor or mount it on machine mounts.

lthough 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.

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.

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.

PREPARATION

Bolting to Concrete Floors

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.

Anchor

Stud

and Anchor

Figure 4. Common types of fasteners for bolting

machinery to concrete floors.

Machine Mounts

Machine mounts are rubber pads mounted to
a threaded stud, which can be fastened to the
bottom of the machine.

Assembly

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.

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

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.

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.

lso, mounts may reduce the total surface area
of machine-to-floor contact, depending on the
design of the machine.

Power Connection

PREPARATION

3. Locate the power transformer in the

electrical panel (see Page 48, Figure 50)
and remove the wire attached to the 110V
terminal and connect it to the 220V terminal.

For Machines Mfg. Since 8/09

Electrocution or fire
may occur if machine is
ungrounded, incorrectly
connected to power, or
connected to an undersized
circuit. Use a qualified
electrician to ensure a safe
power connection.

Once your machine is set up and assembled as
previously described in this manual, it is ready to
be connected to the power source.

Use the information in this section to determine
the power source requirements needed to operate
this machine. If your existing power source does
not meet the stated requirements, consult with a
qualified electrician about running a new circuit.

Note About Extension Cords: Using an
incorrectly sized extension cord may decrease the
life of electrical components on your machine.

Note About 3-Phase Power (SB1022 Only):
DO NOT use a static phase converter to create
3-phase power—it can quickly decrease the life
of electrical components on your machine. If you
must use a phase converter, only use a rotary
phase converter and connect the wild wire to the
correct power connection terminal, shown in the
wiring diagram on Page 47.

OPERATION

Operation Overview

The purpose of the operation section is to
familiarize you with the basic controls,
terminology, capabilities, and adjustments that
are necessary to use this machine.

To better understand the remaining parts of
this section, please take a moment to read this
overview.

To reduce the risk of
serious injury when using
this machine, read and
understand this entire
manual before beginning
any operations.

To complete a typical operation, the operator
does the following:

1. Examines the workpiece to make sure it is
suitable for cutting.

4. Adjusts the upper blade guide height to
approximately
for maximum blade support.

5. Puts on safety glasses, and rolls up sleeves
or secures any clothing or hair that could get
entangled with moving parts.

1

⁄8"–1⁄4" above the workpiece

Loose hair, clothing, or
jewelry could get caught
in machinery and cause
serious personal injury.
Keep these items away
from moving parts at all
times to reduce this risk.

During operation, small
metal chips may become
airborne, leading to serious
eye injury. Wear safety
glasses to reduce this risk.

2. Checks to make sure blade tension is correct,
and the blade guides are positioned correctly.

3. Marks the cut line on the workpiece.

Workpieces that cannot be stabilized from
unexpected movement should not be cut with
a vertical metal bandsaw due to the increased
risk of the operator's hands slipping into the
blade. Examples are chains, cables, balls, or
workpieces with built-in moving parts.

6. Turns the bandsaw ON, and adjusts blade
speed for the type of material being cut.

7. Presses the workpiece against the blade,
using light and even pressure and following
the cut line with the blade.

Depending on the workpiece material, the

operator may squirt a small amount of
cutting fluid at the cutting area to keep it
from overheating and smoking.

8. Turns the bandsaw OFF.

Blade Changes

!

To replace the blade:

1. DISCONNECT BANDSAW FROM POWER!

2. Open the upper and lower wheel doors,

release tension on the blade, and move the
blade guides away from the blade.

3. Put on heavy gloves, then slide the blade
off the upper and lower wheels, around the
blade post, and through the table slit.

4. Install a new blade in reverse order.

Always disconnect power
to the machine when
changing blades. Failure
to do this may result in
serious personal injury.

All saw blades are
dangerous and may cause
personal injury. To reduce
the risk of being injured,
wear leather gloves when
handling saw blades.

Note: Excessive blade contact with the wheel

flange during operation could lead to blade
and wheel damage.

6. Re-tension the blade (refer to the following
Blade Tensioning section).

7. Rotate the top wheel clockwise by hand

several times to make sure the blade tracks
evenly without wandering across the wheel
surface.

Note: If the blade wanders across the wheel

and away from the flange, the wheel
alignment may need to be adjusted. Refer
to Blade Tracking on Page 35 for detailed
instructions.

8. Adjust the upper and lower blade guides
(refer to Adjusting Blade Guides on

Page 26).

9. Close and secure the upper and lower wheel

doors.

Blade Tensioning

To prolong blade life, release the tension
on the blade if the machine will be idle
for an extended period of time.

5. Position the back edge of the blade so that it

is next to, but not against, the flange of the
top wheel (see Figure 14).

Wheel

Flange

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.

The most common causes of blade breakage
are:

s Faulty alignment or adjustment of the blade

guides.

s Forcing or twisting a wide blade around a

tight radius.

s Feeding the workpiece too fast.

s Dull or damaged teeth.

s Over-tensioned blade.

s Top blade guide assembly set too high above

the workpiece. Adjust the top blade guide
assembly so that there is approximately

1

⁄8"–1⁄4" between the bottom of the assembly

and the workpiece.

Note: The blade guide assembly can be lowered

to within 2

s Using a blade with a lumpy or improperly

finished braze or weld.

s Continuously running the bandsaw when not

in use.

1

⁄2" of the table surface.

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.

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.

Blade Break-In

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.

To properly break-in a new blade:

1. Choose the correct speed for the blade and
material of the operation.

2. Reduce the feed pressure by half for the first
50–100 in

3. To avoid twisting the blade when cutting,
adjust the feed pressure when the total
width of the blade is in the cut.

2

of material cut.

s Leaving the blade tensioned when not in use.

s Using the wrong blade pitch (TPI) for the

workpiece thickness. The general rule of
thumb is to have no fewer than two teeth
in contact with the workpiece at all times
during cutting.

Positioning Guide Post

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.

To properly position the guide post:

1. DISCONNECT BANDSAW FROM POWER!

2. Hold the guide post knob with one hand and

loosen the guide post lock knob with the
other (Figure 17).

Guide Post Lock Knob

Adjusting Blade
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.

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.

To properly adjust the upper and lower blade
guides:

1. DISCONNECT BANDSAW FROM POWER!

2. Make sure the bandsaw blade is properly

tensioned (Page 23) and the guide post is
locked.

Tilting Table

The bandsaw table tilts 15° to the left and 15° to
the right for basic cut angles, and 10° to the front
and 10° to the back for feed angles. When used
together, compound angled cuts can be made.

To tilt the table left or right:

1. DISCONNECT BANDSAW FROM POWER!

2. Use an 8mm wrench to loosen the two cap

screws on the cut angle trunnion underneath
the rear of the table (see Figure 23).

Your metal cutting bandsaw is equipped with a
blade welder that uses electrical current to heat
and fuse the blade ends together. This process
will leave the joint brittle, so an annealer is
also included to give the blade strength and
flexibility.

To tilt the table forward or backward:

1. DISCONNECT BANDSAW FROM POWER!

2. Use a 6mm hex wrench to loosen both sets

of cap screws on the two feed angle tilt scale
brackets (see Figure 23).

3. Using the two scales, adjust the angle of the
table for cutting a compound angle, then re­tighten the cap screws.

The electric current that flows through the
blade welder during operation could cause
serious personal injury or death. To reduce
the risk of electrocution or burns, never touch
any metal part of the welding station or blade
during welding or annealing.

To weld the ends of blade together:

1. Turn the bandsaw motor OFF.

2. Place the blade evenly against the back of

the blade shear and firmly pull the handle
down to square off the blade end (see Figure

24).

For Machines Mfg. Since 8/09 Model SB1021/SB1022

OPERATION

Note: To make a proper blade weld, the ends of

the blade must be evenly butted together
during the welding process. If necessary, use
the grinder to square up the ends or remove
any teeth that are in the welding zone (see
Figs. 25–26).

Figure 25. Using the grinder to square up the blade

end.

5. Loosen the welding clamps by pulling the
lock levers down.

6. Position the back of one blade end evenly
against the back of the welding clamp so
that the end is midway between the two
clamps, then rotate the lock lever as far up
as possible to hold the blade end in place (see
Figure 27).

blade material and the clamps are free from
any debris or flash before each use.

3. To ensure correct electrical continuity while
welding, use mineral spirits to clean off all
oil and debris from the first 6" of each end of
the blade.

4. Set the clamping pressure to 0" with the
clamping pressure dial (Figure 29).

Figure 27. Blade end properly position in welding

Light generated during the welding process
could cause serious eye damage. To reduce
your risk, always use eye protection approved
for welding when using the blade welder.

Burning sparks may be thrown in all
directions while welding. Protect yourself from
injury by not welding near flammables and
wearing spark-resistant clothing/gloves. Keep
fire extinguishing equipment readily available.

9. Press and release the welding button. The
blade ends will be welded together.

10. Rotate the lock levers down to release the
welding clamps, then rotate the clamping
pressure dial to "0".

— If the weld is NOT satisfactory, begin

again at Step 2.

12. Place the blade in the welding clamps with
the weld centered between the clamps and
re-tighten the lock levers.

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.

experiment from there.

—Carbon Steel ..................... Dull Cherry Red

—Carbon Steel Hard Back ...................... Blue

—Bi-Metal ........................................... Orange

—High Speed Steel .............. Dull Cherry Red

14. Repeat Step 13 three to four more times,
allowing the weld to cool for about 30
seconds between each repetition. Each time
reduce the amount of time you press the
anneal button, to reduce the amount of heat
successively.

15. Allow the blade to cool, then re-inspect the
weld.

17. Re-clamp the blade in the welding clamps
with the joint centered, then repeat the
annealing process twice more. Each time
gradually reduce the amount of time you
anneal the weld.

18. Test the strength and flexibility of the weld
by bending the blade in an arc similar to that
of the bandsaw wheels. The blade should
bend in a smooth circular, rounded shape—
rather than a pointed fold (see Figure 31).

Note: Make sure not to grind the teeth or

blade body, or overheat the blade during
grinding—this will weaken the blade. A
small amount of ticking is acceptable during

V-Belts

To ensure optimum power transfer from the
motor to the blade, the V-belts must be in good
condition and operate under proper tension.

Check V-belt tension at least every three
months—more often if the bandsaw is used daily.
V-belts stretch with use and must be periodically
re-tensioned. Replace the V-belts if they are
cracked, frayed, or badly worn. Refer to Figure
38 to identify V-belt locations.

Dressing Rubber Tires

As the bandsaw ages, the rubber tires on the
wheel may need to be redressed if they become
hardened or glazed over. Dressing the rubber
tires improves blade tracking and reduces
vibration/blade lead.

If the rubber tires become too worn, then blade
tracking will become extremely difficult. At that
point, redressing will no longer be effective, and
the rubber tires must be replaced.

To redress the rubber tires:

1. DISCONNECT BANDSAW FROM POWER!

2. Put on heavy gloves and remove the blade.

3. Use a brush and shop vacuum to clean any

chips from the rubber tires.

4. Hold a piece of 100-grit sandpaper against
the rubber tire and rotate the wheel by hand.
Only redress the rubber enough to expose a
fresh rubber surface.

Table Calibration

A blade that is tracking correctly runs cooler,
reduces wear-and-tear on the machine, and
increases cutting performance. When tracking
correctly, the blade rides next to, but not against,
the wheel flange. The tracking is controlled by
adjusting the upper wheel.

To adjust the upper wheel for blade tracking:

1. DISCONNECT BANDSAW FROM POWER!

2. Make sure the blade guides are adjusted

away from the blade so they will not
interfere with the change of blade position.

3. Ensure that the blade is correctly tensioned.

4. Using a 6mm hex wrench, loosen the four
locking cap screws (Figure 39).

Pinion Gear Backlash

During the life of the machine, the variable
speed handwheel may develop extra backlash
due to normal wear of the pinion gears. If this
lash becomes unacceptable, use this procedure to
reduce the backlash.

To reduce the pinion gear backlash:

1. DISCONNECT BANDSAW FROM POWER!

2. Remove the rear lower access panel, and use

a 4mm hex wrench to loosen both pinion gear
locking set screws (Figure 44) just enough
to adjust the pinion gears.

Pinion Gears

Leadscrew End Play

If you notice that the leadscrew has end play
and the variable speed handwheel has excess
backlash after the pinion gear lash has been
set, you can adjust the lead screw collars as an
additional measure to reduce the backlash.

To adjust the lead screw collars to reduce
backlash:

1. DISCONNECT BANDSAW FROM POWER!

2. Remove the rear lower access panel, and

use a 4mm hex wrench to loosen both collar
locking set screws just enough to adjust the
collars (Figure 45).

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!

Wire Connections: All connections must be

2.

tight to prevent wires from loosening during
machine operation. Double-check all wires
disconnected or connected during any wiring
task to ensure tight connections.

Modifications: Using aftermarket parts or

3.

modifying the wiring beyond what is shown
in the diagram may lead to unpredictable
results, including serious injury or fire.

Motor Wiring: The motor wiring shown

4.

in these diagrams is current at the time of
printing, but it may not match your machine.
Always use the wiring diagram inside the

Circuit Requirements: Connecting the

5.

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.

Capacitors/Inverters: Some capacitors and

6.

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.

Wire/Component Damage: Damaged wires

7.

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.
