or under the effects of drugs, alcohol or any medi-
cation that impairs reflexes or alertness.
2. The working area should be well lit, clean and free
of debris.
3. Keep children and visitors at a safe distance when
the bandsaw is in operation; do not permit them to
operate the bandsaw.
4. Childproof and tamper proof your shop and all
machinery with locks, master electrical switches
and switch keys, to prevent unauthorized or unsu-
pervised use.
5. Stay alert! Give your work your undivided attention.
Even a momentary distraction can lead to serious
injury.
6. ine particulate dust is a carcinogen that can be
hazardous to health. Work in a well-ventilated area
and whenever possible use a dust collector. Wear
face, eye, ear, respiratory and body protection de-
vices.
7. Do not wear loose clothing, gloves, bracelets,
necklaces or other jewelry while the bandsaw is in
operation.
8. Be sure that adjusting wrenches, tools, drinks and
other clutter are removed from the machine and/or
the table surface before operating.
9. Keep hands well away from the blade and all mo-
ving parts. Use a brush, not hands, to clear
away chips and dust.
10. Adjust and position upper and lower blade guides
before starting to cut. Upper blade guide should be
adjusted to approximately 1/8” above the material
to be cut.
11. Adjust blade tension and tracking before starting to
cut.
12. Saw teeth must point down toward the table.
13. Be sure that the blade has gained full operating
speed before starting to cut.
14. Always use a clean, properly sharpened blade.
Dirty or dull blades are unsafe and can lead to
accidents.
15. Use suitable workpiece support if the workpiece
does not have a flat surface.
16. Hold material firmly against the table.
17. Do not work on long stock without adequate sup-
port on the out feed end of the table.
18. If using a power feeder, stop the feeder before stop-
ping the bandsaw.
19. Do not push or force stock into the blade. The band-
saw will perform better and more safely when work-
ing at the rate for which it was designed.
20. Avoid working from awkward or off balance posi-
tions. Do not overreach and keep both feet on floor.
21. Keep guards in place and in working order. If a
guard must be removed for maintenance or clea-
ning be sure it is properly re-attached before using
the tool again.
22. Never leave the machine unattended while it is run-
ning or with the power on.
23. Use of parts and accessories NOT recommended

ELECTRICAL REQUIREMENTS
CIRCUIT CAPACITY
Make sure that the wires in your circuit are capable of
handling the amperage draw from your machine, as
well as any other machines that could be operating on
the same circuit. If you are unsure, consult a qualified
electrician. If the circuit breaker trips or the fuse blows
regularly, your machine may be operating on a circuit
that is close to its amperage draw capacity. However, if
an unusual amperage draw does not exist and a
power failure still occurs, contact a qualified technician
or our service department.
BEFORE CONNECTING THE MACHINE TO THE POWER SOURCE, VERIFY THAT THE VOLTAGE OF YOUR POWER SUPPLY CORRE-
SPONDS WITH THE VOLTAGE SPECIFIED ON THE MOTOR I.D. NAMEPLATE. A POWER SOURCE WITH GREATER VOLTAGE THAN
NEEDED CAN RESULT IN SERIOUS INJURY TO THE USER AS WELL AS DAMAGE TO THE MACHINE. IF IN DOUBT, CONTACT A QUAL-
IFIED ELECTRICIAN BEFORE CONNECTING TO THE POWER SOURCE.
THIS TOOL IS FOR INDOOR USE ONLY. DO NOT EXPOSE TO RAIN OR USE IN WET OR DAMP LOCATIONS.
EXTENSION CORDS
If you find it necessary to use an extension cord with your
machine, use only 3-wire extension cords that have 3-
prong grounding plug and a matching 3-pole recepta-
cle that accepts the tool’s plug. Repair or replace a
damaged extension cord or plug immediately.
Make sure the cord rating is suitable for the amperage
listed on the motor I.D. plate. An undersized cord will
cause a drop in line voltage resulting in loss of power
and overheating. The accompanying chart shows the
correct size extension cord to be used based on cord
length and motor I.D. plate amp rating. If in doubt, use
the next heavier gauge. The smaller the number, the
heavier the gauge.

P ACEMENT WITHIN THE SHOP / ESTAB ISHING A SAFETY ZONE
P ACEMENT WITHIN THE SHOP
This machine should be installed and operated only on a
solid, flat and stable floor that is able to support the weight
of the bandsaw and the operator. Using the dimensions
shown as a guideline, plan for placement within your shop
that will allow the operator to work unencumbered and
unobstructed by foot traffic (either passing shop visitors or
other shop workers) or other tools or machinery.
BASIC FUNCTIONS OF THE UNIT
This Deluxe 14" Wood Cutting Bandsaw is supplied with a
3/4" wide general purpose blade and is designed to
accommodate blade widths from 1/8" to 3/4". Ideal blade
length for this model 90-170B M1 is 112" (2845 mm).
Note:Generallyspeaking,becausetheupperwheelheightis
somewhatadjustable(toallowforbladetensioning),ablade
lengthvariationofplusorminus1/2"fromthe“idealblade

Maximum inboard width of cut (space between the blade
and the body of the saw A) is 13 1/2".
or cutting thicker stock or for resawing, the maximum
depth of cut B(or max. workpiece height) is 12".
An adjustable rip fence Cis supplied to serve as a straight-
edge to guide the workpiece for longer rip cuts. The fence
can easily be removed and set aside when not required,
for example when making curved cuts.
A
ESTAB ISHING A SAFETY ZONE
or shops with frequent visitors or multiple operators, it is
advisable to establish a Safety Zone around shop machin-
ery. A clearly defined “no-go” zone on the floor around
each machine can help avoid accidents that could cause
injury to either the operator or the shop visitor. It is advisable
to take a few moments to either paint (using non-slip paint)
or using tape, define on the floor the limits or perimeter of each machines safety zone. Take steps to ensure that all
operators and shop visitors are aware that these areas are off limits whenever a machine is running for everyone
but the individual operating the unit. 9

ATTACHING THE TABLE
The wor table mounts on a brac et which allows
adjustment from flat (0°) to any angle up to 45° to the
right. Adjustments can be made easily with the angle
scale and loc nobs.
1. Remove the red insert Afrom the center of the
table and the table alignment pin Bfrom the
table slot.
The protective coating on the saw table prevents rust from
forming during shipping and storage. Remove it by rub-
bing with a rag dipped in erosene, mineral sprits or paint
thinner. (Dispose of potentially flammable solvent-soa ed
rags according to manufacturer’s safety recommenda-
tions.)
A putty nife, held flat to avoid scratching the surface, may
also be used to scrape off the coating followed by clean-
up with solvent. Avoid rubbing the saw’s painted surfaces,
as many solvent-based products will remove paint.
To prevent rust, apply a light coating of paste wax or use
regular applications of any after-mar et surface protectant
or rust inhibitor.
CLEAN UP
SERIOUS PERSONAL INJURY COULD OCCUR IF YOU CONNECT THE SAW TO THE POWER SOURCE BEFORE YOU HAVE
COMPLETED THE INSTALLATION AND ASSEMBLY STEPS.
DO NOT CONNECT THE SAW TO THE POWER SOURCE UNTIL INSTRUCTED TO DO SO.

OFF POSITION BEFORE RE-SETTING THE THERMAL RELAY.
To reset the thermal relay after it has been tripped: set the
power switch to the “off” position and press the thermal
relay re-set button D, then restart the machine.
The unit is equipped with a thermal relay (circuit breaker)
D located under the magnetic switch, to protect the motor
from power surges or spikes in line voltage. In the event of a
power surge, the thermal relay will be automatically tripped
thereby cutting off the power to the motor.

B ADE SE ECTION
There are a variety of different types of bandsaw blades on the market to suit various cutting applications. Your results
may vary based on usage, experience and personal preference.
Standard size - 112” (2845 mm) - replacement blades made from high carbon steel can be purchased in a variety of
widths from your General® International dealer under the following parts numbers:
•#90170-B14:1/4” - 6 TPI, blade thickness: 0.65 mm •#90170-B38: 3/8” - 6 TPI, blade thickness: 0.50 mm
•#90170-B12: 1/2” - 4 TPI, blade thickness: 0.65 mm •#90170-B34: 3/4” - 4 TPI, blade thickness: 0.65 mm
or (depending on availability) from your local tool dealer. These are standard sizes that should be readily available
in most areas. The use of any other size is not recommended and can lead to serious injury and/or damage to the
machine.
Some general guidelines to consider when choosing bandsaw blades:
• Wider blades with fewer teeth per inch are best suited to cutting straight lines, re-sawing and for sweeping curves,
but will not turn tight radius curves. They will cut quickly and aggressively but do have a tendency to bind (or get
stuck in the cut) if turned too sharply.
•Narrower, thinner blades with more teeth per inch will cut more slowly but can turn much tighter corners for cutting
more intricate work.
Common causes of blade breakage:
• Poor guide bearing alignment and adjustment. • eeding the workpiece too quickly.
• orcing or twisting a wide blade around a short radius. • Dull teeth.
• Setting blade guard assembly too high above the workpiece. • Too much blade tension.
• Lumpy or improperly finished braze or weld on the blade. • Continuous running of blade when not cutting.

3. Remove the table alignment pin from the table slot and the red circular insert from the center of the table.
4. With the blade perpendicular to the wheels, guide it
through the table slot, then rotate the side of the blade
nearest you back toward the left side of the wheels.
5. eed the blade into the left blade guard and around the
wheels. Make sure the blade teeth point forward Aand
down B.
With the blade properly installed, proceed to blade tension
adjustments and blade tracking adjustments, as per instruc-
tions on the next few pages.

1. Refering to the blade tension scale A, set the blade
tension to correspond with the width of the blade
installed on your bandsaw. Adjust the blade ten-
sion by lifting the blade tension handle B, then by
turning it:
- Clockwise to tighten
- Counter-clockwise to loosen the blade tension.
Determining ideal blade tension is somewhat subjective. It is learned through practice and experience and is some-
what dependant on personal preference and individual work habits.
A properly tensioned blade is critical to obtaining maximum performance from any bandsaw. A properly tensioned
blade will last longer and be much less likely to break prematurely. If the blade tension is too loose you will notice
that the blade will have a tendency to drift or slip off-line when cutting and you will have more difficulty controlling
your cuts. A blade that is tensioned too tightly will break prematurely and will be difficult to work with when making
tighter radius cuts.
The following information can be used as a guideline or starting point to assist you in determining ideal blade ten-
sion for your needs:
•When working with wider blades, re-sawing taller stock, making straight cuts or wide sweeping curves tight-
er blade tensions will provide better results.
•When working with narrower blades, sawing shorter stock and making tighter curved cuts are best per-
formed using less tension
This model 90-170B M1 bandsaw is equipped with a blade tension scale, which can be used as a reference for the
ideal setting with various blade widths.

ADJUSTING BLADE TRACKING
Blade trac ing means centering the blade on the wheels A.
Ideally, the blade should stay relatively centered on both
the upper and lower wheels.
Due to natural variations in castings, blade thic ness or den-
sity and tire wear, absolute perfect centering alignment is
rarely attainable. A slight misalignment of the blade on the
wheels is inevitable and as long as it is ept to a minimum
(following the steps listed below) will not hinder the perform-
ance of the saw.
This misalignment is controlled and ept to a minimum by
adjusting the tilt angle of the upper wheel.
When adjusting blade trac ing to center the blade on the wheels and assuming that perfect centering is not attain-
able, it is preferable to have the blade slightly off-center towards the front of the wheels rather than towards the rear
because the teeth on most bandsaw blades have alternating hoo (one inner, one outer) – therefore if the blade is
centered too far bac on the wheel (or if the blade tension is too tight), inner hoo ed teeth will dig into the wheel
tire and cause premature wear of the tire.
Nonetheless, to avoid having the blade come off of the wheels on it’s own during operation, the front edge of the
blades teeth should never be any closer than 3 mm (1/8”) from the front edge of the wheel B.

3 mm - 1/8"
To adjust the blade trac ing:
1. Open the upper wheel cover door then rotate the wheel
slowly forward by hand Aand chec the position of the
blade on the wheel. The blade should remain as cen-
tered as possible on the wheel as it turns B.
2. If the blade trac ing must be adjusted, loosen the loc
nut Con the trac ing adjustment nobs D, then turn the
nobs:
- Cloc wise if the blade moves toward the front of
the wheel. This tilts the top of the wheel to the bac
and moves the blade toward the center.
- Countercloc wise if the blade moves toward the
bac edge. This tilts the top of the wheel to the front
and moves the blade toward the center.

ADJUSTING THE UPPER / OWER B ADE GUIDES ASSEMB IES
The guide bearings Akeep the blade from moving from
side to side during cutting and must be snug but not
touching the blade in order to ensure accurate cuts. The
space between each guide bearing and the blade must
not exceed 0.02" (the thickness of a sheet of paper). If less
space is left, the blade will get stuck or jammed between
both bearings. Too much friction will cause blade to over-
heat and break.
Also, the guide bearings must remain at least 1/32” be-
hind the blade teeth to prevent damage to the blade B.
The thrust bearing Ckeeps the blade from moving back
and out of position when the work is being fed into the
blade and must be very close to the back of the blade to
prevent damage to the blade during cutting.
