ELECTRICAL REQUIREMENTS
GROUNDING INSTRUCTIONS
In the event of an electrical malfunction or short circuit, grounding reduces the risk of electric shock. The motor of this machine is wired for 110V single phase operation and is equipped with a 3-conductor cord and a 3­prong grounding plug A to fit a grounded type recep­tacle B.Do not remove the 3rd prong (grounding pin) to make it fit into an old 2-hole wall socket or extension cord. If an adaptor plug is used C, it must be attached to the metal screw of the receptacle.
Note: The use of an adaptor plug is illegal in some areas. Check your local codes. If you have any doubts or if the supplied plug does not correspond to your elec­trical outlet, consult a qualified eletrician before pro­ceeding.
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 depar tment.
BEFORE CONNECTING THE MACHINE TO THE POWER SOURCE,VERIFY THAT THE VOLTAGE OF YOUR POWER SUPPLY CORRESPONDS 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 DAMA GE T O THE MACHINE. IF IN DOUBT, CONTACT A QUALIFIED 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 3­prong grounding plug and a matching 3-pole recepta­cle 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.

PLACEMENT WITHIN THE SHOP / ESTABLISHING A SAFETY ZONE
THIS MODEL 90-140 M1 BANDSAW IS HEAVY (191 LBS - 87 KG). DO NOT OVER-EXERT. THE HELP OF AN ASSISTANT WILL BE NEEDED FOR THE FOLLOWING STEP.
PLACEMENT 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 191 LBS (87 kg) 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 14" wood cutting bandsaw is supplied with a 3/8" wide general purpose blade and is designed to accommodate blade widths from 1/4" to 3/4".Ideal blade length f or this 90­140 M1 model is 93 1/2" (2375 mm).
Note: Generally speaking, because the upper wheel height is somewhat adjustable (to allow for blade tensioning), a blade length variation of plus or minus 1/2" from the “ideal blade length” can be accommodated.
Maximum inboard width of cut (space between the blade and the body of the saw A) is 13 1/2".
For cutting thicker stock or for resawing, the maximum depth of cut B (or max. workpiece height) is 6" (up to 12" with optional “riser block kit”item #90-130A – Refer to section “Recommended Optional Accessories for your Bandsaw”.

B
ESTABLISHING A SAFE
TY ZONE
For shops with frequent visitors or multiple operators, it is advisable to establish a Safety Zone around shop machin­ery. 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.
The protective coating on the saw table prevents rust from forming during shipping and storage. Remove it by rubbing with a rag dipped in kerosene,mineral sprits or paint thinner. (Dispose of potentially flammable solvent­soaked rags according to manufacturer’s safety recom­mendations.)
A putty knife, 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-market surface protec­tant or rust inhibitor.
CLEAN UP
Tip: With a screw driver, push a solvent-saturated rag into the T-slot to remove the grease so the miter gauge will slide freely.

6. With the blade perpendicular to the wheels, feed the blade through the table slot to free it from the saw G.
7. Carefully hang the blade on a hook in a safe, dry place in your workshop if it will be re-used, or dispose of it safely if it is worn or damaged.
Do not attempt to coil up the blade as it was when you first purchased it as it has a tendancy to pop open unexpectedly and could cause injury.
Blade teeth are sharp. Use care when handling a saw blade.
BLADE SELECTION
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 - 93 1⁄2”(2375 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:
#90125-B14: 1/4” - 6 TPI, blade thickness: 0.65 mm
#90125-B38: 3/8”- 6 TPI,blade thickness: 0.50 mm
#90125-B12: 1/2”- 4 TPI,blade thickness: 0.65 mm
#90125-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 injur y 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. • Feeding the workpiece too quickly.
• Forcing 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.
F
G
To install a blade:
1. Turn off the bandsaw and unplug the power cord.
Beware of the blade popping open.
Note: You may want to use a thick shop towel to handle the loose blade or wear a pair of heavy duty work gloves for the following steps.
2. If you are installing a new blade,carefully remove the
blade from its package. Hold it firmly with one hand as you remove the twist ties. Slowly separate the coils of the blade until it unravels into one hoop.

Note: Steps 3 and 4 may be unnecessary if you’ve just removed a blade. (If needed, refer back to the previous page.)
3. Remove the table alignment pin from the table slot and the red circular insert from the center of the table.
4. Remove the right hand side blade guard by loosening the two Phillips head screws,just enough to slide it out.
5. 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.
6. Feed the blade into the left blade guard and around the wheels. Make sure the blade teeth point forward A and down B.
With the blade properly installed, proceed to blade tension adjustments and blade tracking adjustments, as per instruc­tions on the next few pages.
Determining ideal blade tension is somewhat subjective. It is learned through practice and experience and is some­what 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 ten­sion for your needs:
When working with wider blades, re-sawing taller stock, making straight cuts or wide sweeping cur ves tight­er blade tensions will provide better results.
When working with narrower blades,sawing shorter stock and making tighter curved cuts are best per­formed using less tension
This model 90-140 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 TENSION
A
B
C
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 tensioning by turning the blade tension knob B:
a) Clockwise to tighten b) Counter-clockwise to loosen the blade tension.
3. W
ith the saw turned off
, press against the side of the blade to test the tautness of the blade C. For ideal results with most blade widths and cutting applications the blade should flex in no more than 1/4" to 3/8".
4. Make a test cut on a sample piece of wood and if needed re-adjust the blade tension
Note: To prolong the life of the blade whenever the bandsaw is not in use for prolonged periods (more than 24 hours), release the blade tension lever to remove tension from the blade, Over time, maintaining tension on a blade that is not in use will cause the blade to deform, by taking the shape of the wheels at both extremities. This can weaken the blade and cause premature breakage.
17
ADJUSTING BLADE TRACKING
Blade tracking 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 thickness or den­sity 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 kept to a minimum (following the steps listed below) will not hinder the perform­ance of the saw.
This misalignment is controlled and kept to a minimum by adjusting the tilt angle of the upper wheel.
When adjusting blade tracking to center the blade on the wheels and assuming that perfect centering is not attain­able,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 hook (one inner,one outer) – therefore if the blade is centered too far back on the wheel (or if the blade tension is too tight), inner hooked 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.
BLADE CLEARANCE
Note: As previously stated, when performing blade installation, removal, tensioning or tracking, maximum clearance between the blade and both upper and lower bearing assemblies is required to minimize friction, which would be damaging to the blade. Refer back and follow the instructions for “blade clearance” before performing blade track­ing adjustments.
A
To adjust the blade tracking:
1. Open the upper wheel cover door then rotate the wheel slowly forwar d b y hand.The blade should remain as cen­tered as possible on the wheel as it turns A.
2. If the blade tracking must be adjusted, loosen thumb nut B, then turn the tracking knob C,located on the rear of the bandsaw:
a) Clockwise if the blade moves toward the front of the
wheel.This tilts the top of the wheel to the back and mo­ves the blade toward the center.
b) Counter-clockwise if the blade moves toward the back
edge.This tilts the top of the wheel to the front and mo­ves the blade toward the center.
Note: Turn the tracking knob in 1/2 turn increments, re­check and adjust again as needed.

ADJUSTING THE UPPER GUIDES BL
OCKS AND THRUST BEARING
The blade guides blocks keep 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 block 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 blocks.Too much friction will cause blade to overheat and break.Also,the guide blocks must remain at least 1/32”behind the blade teeth to prevent damage to the blade.
The thrust bearing keeps 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.
Adjus
t the positioning of the upper blade guides blocks:
ADJUSTING THE BLADE GUARD FOR DEPTH OF CUT
1/8” - 1/4”
The blade guard can be moved up or down to accom­modate the height of the work to be cut. To prevent the blade (which is flexible and which would not otherwise be supported) from slipping out of position during cut­ting, and to reduce risks of injur ies, a minimum amount of blade should be exposed
.
The blade guard should be set 1/8” - 1/4” above the work­piece Ato prevent the blade from flexing out of position or off-line during cutting.
Adjust the height of the blade guard B to suit the thick­ness of the workpiece as follows:
1. Make sure the bandsaw is turned off and the power cord is disconnected from the power source.
2. Loosen the smaller lock knob C.
3. Move the blade guide assembly up or down D,then re-tighten the lock knob C.
Note: The depth gauge Eon the front of the blade guard can be used as a reference but it is not intended for high preci­sion measurements.
1. Loosen the two set screws A using the supplied 3 mm
Allen key.
2. Push the guide blocks B towards the blade.
To avoid injury, make sure that the switch is in the “OFF” position and that the power cord is unplugged before performing any adjustments on the bandsaw.

Note: Before adjusting the upper and lower blade guides and thrust bearings, make sure the blade is tensioned and track­ing properly. Adjust the upper and lower blade guides and thrust bearings after each blade tension and tracking adjust­ment. Whenever the upper blade guide and thrust bearing are adjusted, the lower blade guide and thrust bearing should also be adjusted.

CHANGING SPEED SETTINGS
This model 90-140 14" wood cutting bandsaw has 2 different speed settings; low and high.
- Low speed is to be used for cutting soft woods over 4" in height or hard woods over 2" in height.
- High speed is best for cutting soft woods under 4" in height or hard woods under 2" in height.
Note: If wood starts to burn at high speed, stop and change to the lower speed setting.
To change the speed setting:
1. Turn off power and disconnect the bandsaw from the po­wer source to avoid unintentional start-up of the bandsaw.
2. Open the lower wheel cover door.
3. At the back of the bandsaw,just above the motor, there is
a ratchet lever A for loosening the tension on the drive belt.When y ou pull it out,as in A, it disengages for resetting. When you release it as in B, it engages the bolt for s crewing or unscrewing. (You can tell when it is engaged by the orange indicater button B showing).
To loosen the drive belt, unscrew the bolt a few turns counter­clockwise then pull up on the capacitor cover of the motor C pivot the motor to the left.This loosens the belt enough to move it between one set of pulleys and the other.
4. To set the bandsaw speed to the slower setting; 1630 FPM
(495MPM), place the belt on the frontmost set of pulleys as in D.
5. To set the bandsaw speed to the faster setting; 2730 FPM
(832MPM), place the belt on the rear most set of pulleys as in E.
6. Having repositioned the belt, push down firmly on the mo-
tor capacitor cover to tighten the belt, then turn the ratch­et lever clockwise until it is tight and the motor does not move.

1. Turn off the bandsaw and unplug the power cord.
2. Adjust blade tension.
3. Adjust blade tracking.
4. Adjust upper blade guides and thrust bearing.
5. Adjust lower blade guides and thrust bearing.
CHECKLIST BEFORE STARTING
These additional safety measures should be be included in your checklist:
6. Make sure all the blade guards are in place.
7. Make sure the bandsaw table and work area in general are clean and free of sawdust and debris. These steps should always be followed when any adjustment is performed, the blade is changed, or periodically as vibra-
tion and normal wear and tear on the machine could throw these parts out of alignment.

CONNECTING TO A DUST COLLECTOR
A dust port with a 2.5” opening is provided to accommodate connection to a dust collector (not included).
Once the dust port has been installed (See Previous section “Attaching the dust port”), be sure to use appropriate sized hose and fittings (not included) and check that all connec­tions are sealed tightly to help minimize airborne dust.
If you do not already own a dust collection system consider contacting your General® International distributor for informa­tion on our complete line of dust collection systems and accessories or visit our Web Site at: www.general.ca.
OPERATIONS STEP-BY-STEP
1.
Trace the cutting line on your workpiece with a pencil.
2. Set the height of the blade guard according to the thickness of your workpiece (see section: “Adjusting the bla­de guard for depth of cut”on page 19.)
3. If a dust collector is connected to your bandsaw,turn it on.
To reduce the risk of damage to the bandsaw or the workpiece, as well as a potential for personal injury, after ini­tial set-up as well as before each use, make sure that everything is securely installed and that all fasteners and moving parts on this bandsaw are locked in place before starting the machine.
Make sure to have on safety glasses at all times when using the bandsaw.
Make sure you are wearing safe appropriate workshop attire. Roll up long sleeves, secure long hair and remove any jewelry: watches,rings, bracelets or anything that could get stuck into the moving parts of the bandsaw,poten­tially causing serious injuries.
4.
Pull the switch toward you to start the bandsaw.
Note: The yellow safety key must first be inserted into the switch.
5. Align the cutting line on your workpiece with the blade and feed the workpiece into the blade.
Tip: The use of a roller stand provides an extra support for more convenience when working with longer workpieces.
TO STOP THE MACHINE
1. Push the red tab down and remove the yellow key.
2. Turn your dust collector off.
USING THE MITER GAUGE
The miter gauge allows for easier and safer sawing by pr oviding workpiece support when cutting straight (90°) or angled ends (0° to 30°). The miter gauge supplied with your bandsaw is adjustable from 0° to 30° right to left.
To use a setting other than 90°, loosen the lock knob A by turn­ing it counter-clockwise. Rotate the miter head to the required angle B , shown on the angle indicator.Then turn the lock knob
A clockwise to tighten it.

23
CUTTING CURVES
When cutting curves, carefully turn the workpiece so the blade follows without twisting. If the curve is so sharp that you repeatedly back up and cut new kerf,use a narrower blade,or a blade with more set (teeth further apar t). When a blade has more set, the workpiece turns easier but the cut is rougher.
When changing a cut, do not withdraw the workpiece from the blade.The blade may get drawn off the wheels.
To change a cut,turn the workpiece and cut your way out through the waste material area.
When cutting long curves, make relief cuts as you go along.
CUTTING CIRCLES
1. Adjust the blade guard assembly to 1/8" above the workpiece.
2. Use both hands while feeding the work into the blade. Hold the workpiece firmly against the table.Use gentle pressure.Do not force the work.Allow the blade to cut.
3. The smallest diameter circle that can be cut is deter­mined by the width of the blade.For example, a 1/4" wide blade will cut a minimum diameter of approxi­mately 1-1/2" .

1. Inspect/test the ON/OFF switch before each use.Do not operate the bandsaw with a damaged switch; replace a damaged switch immediately.
2. Periodically inspect the power cord/plug and the blade for damage.
Never operate the bandsaw with any damaged part. Replace a damaged part at the first visible signs of damage.
PERIODIC MAINTENANCE & LUBRICATION
Disconnect machine from power source, before performing any lubrication or maintenance.
Keep the rack and pinion A as well as the blade tension adjustment screw B well greased and free of dust or debris. Clean and remove dust,debris, and old grease after every 10-15 hours of use. After cleaning, reapply grease as need­ed. (Use any all purpose grease.)
The motor and all bearings are sealed and permanently lubricated – no further lubrication is required. No other part of this bandsaw needs lubrication.

3. Keep the machine clean and free of sawdust. Frequently blow out or vacuum up the sawdust and wipe down
the machine occasionally with a damp rag.
Note: The wheels must always be kept clean. Dirt on the wheels will cause blade slippage.
4. Do not allow dirt, pitch or gum to build up on the table, blade, guide/thrust bearings. Clean as needed with
gum and pitch remover.
Note: Do not immerse the bearings in the gum and pitch remover.
5.
To prevent rust from forming on the unpainted cast iron of the table, and so that the wood slides easily while cutting, a pply a light coating of paste wax or use regular applications of any after-market surface protectant or rust inhibitor.
To avoid eye injury from blowing debris, wear safety goggles when blowing out sawdust.
REPLACING THE BANDSAW BLADE
The blade should be replaced when worn out. Refer to the following symptoms to determine whether or not it is time to replace the blade:
- It is not cutting as fast.
- It is not able to follow a cutting line as it used to.
REQUIRED MAINTENANCE
REPLACING THE UPPER AND LOWER THRUST BEARINGS
1. Turn the tension knob A counter-clockwise for the blade to be loose enough to remove easily.
2. Remove the right hand side blade guard B by loos­ening the two phillips head screws C, just enough to slide it out.
3. Loosen the upper thumb screw D.

REPLACING THE WHEEL TIRE
Wheel tires must be replaced if they get worn out or dam­aged. (If it is worn out, the blade will not track straight on the wheels.)
Use a flat screwdriver to remove the tire from the groove on the wheel, then install a new tire.
Note: When replacing the tires, stretch them around the wheels but do not glue them on.
ADJUSTING/REPLACING THE LOWER WHEEL BRUSH
The lo
wer wheel is equipped with a cleaning brush that prevents pitch and sawdust build up on the lower tire.
Any pitch and sawdust that builds up on the upper wheel tire should be removed with a stiff brush or scraped off with a piece of wood.
Note: To avoid damaging the tire do not use a sharp knife or any kind of solvent to remove pitch build up.
Verify that the brush keeps the lower wheel surface clean at all times. With use and normal wear over time, the brush hairs will soften and will not clean the surface of the wheel as well. You then must lower the brush slightly. Proceed as follows:
1. Loosen the Phillips head screw A.
2. Slide the brush slightly down along the mounting hole B of it’s mounting bracket, so that a fresh, s tiffer part of
the hairs touches the wheel tire.
3. Tighten the screw to lock the brush in position.
REPLACING LOWER WHEEL MOTOR BELT
The lower wheel is driven by one belt mounted on either of the two pulleys powered by the motor.The belt’s tension should be verified upon reception of the machine, then every 6 months. Slightly push on the belt with your finger. The belt must not move more than 1/8". If the belt becomes too loose due to wear or if a breakage occurs, you must replace it.
1. Turn off power and disconnect the bandsaw from the power source to avoid unintentional start-up.
2. Open the lower wheel cover door.
3. If needed, loosen the belt, proceeding as per step 3 in section “Changing speed settings”, on page 21.
4. Remove the belt from the groove in the pulleys and install a new one.
5. Having installed a new belt, push down firmly on the motor capacitor cover to tighten the belt, then turn the
ratchet lever clockwise until it is tight and the motor does not move.
6. Close the lower wheel cover door.
