ELECTRICAL REQUIREMENTS
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 DAMAGE
TO 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.
A
B
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 120 V single phase operation and is equipped with a 3-conductor cord and a
3-prong 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 electrician 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 department.
C
CONVERTING THE MOTOR TO 240V
Note: When converting motor voltage on a machine that
is equipped with a magnetic switch, the switch contactor
must also be changed out for one made for the appropriate voltage, as well as the thermal relay/circuit breaker
and “power in” indicator light (if applicable). Failure to
make these necessary modifications to the switch will lead
to malfunction and permanent switch failure.
Should you need to convert your machine’s motor
from 120 V to 240 V power, contact a qualified electrician. Unless you are a qualified electrician, we do
not recommend attempting this conversion on your
own. If you choose to do so, you may risk serious personal injury, damage to the motor and voiding the
warranty of your machine. We suggest you ask your
local General International distributor to recommend
qualified electricians in your area (or perhaps one of
their own technicians) who can make this conversion
properly and safely.
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 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 / SAFETY ZONE
THIS METAL CUTTING BANDSAW MODEL 90-730 IS HEAVY. DO NOT OVER-EXERT. A HOIST OR FORKLIFT WITH STRAPS
SHOULD BE USED TO LIFT THIS MACHINE. TO LIMIT THE RISK OF SERIOUS INJURY OR DAMAGE TO THE MACHINE,
ANY EQUIPMENT USED TO LIFT THIS MACHINE SHOULD HAVE A RATED CAPACITY IN EXCESS OF 330 LBS (150 KG).
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 machine (330 lbs - 150 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.
ESTABLISHING A SAFETY 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.

INSTALLING A BLADE
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. Ask your local tool dealer for suggestions
for bandsaw blades in 0.035” (0,9 mm) thickness and 3/4” (19 mm) width x 93” (2360 mm) length.
Note: Generally speaking, because one 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.

MAKE SURE THE MACHINE HAS BEEN TURNED OFF AND UNPLUGGED FROM THE POWER SOURCE BEFORE PERFORMING ANY MAINTENANCE OR ADJUSTMENTS.
ADJUSTING BLADE TENSION
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.
The following information can be used as a guideline or starting point to assist you in determining ideal blade tension.This bandsaw is equipped with a blade tension scale, which can be used as a reference for the ideal tension
with various blade widths.
To adjust the blade tension
1. Lower the arm into the horizontal posi-
tion.
2. Turn the handle A clockwise to ten-
sion the blade or counterclockwise to
loosen. The white mark B shoud be centered in the shaded zone C of the tension indicator.
3. Make a test cut on a sample piece and
if needed, re-adjust the blade tension.
Note: To check the blade tension, apply
gentle finger pressure on the blade side
facing you. The blade should not move
more than 0.004”.

ADJUSTING THE BLADE GUIDES
The guide bearings K keep the blade from moving from side to side during the cutting and must be adjusted
close to the blade (but not touching the blade) in order to ensure accurate cuts. The space between each guide
bearing and the blade must not exceed 0.001”. If less space is left, the blade will get stuck or jammed between the
bearings. Too much friction will cause blade to overheat and break.
Note: Before adjusting the blade guides, make sure the blade is tensioned and tracking properly. Re-adjust
the blade guides after each blade tension or tracking adjustment.

MAKE SURE THE MACHINE HAS BEEN TURNED OFF AND UNPLUGGED FROM THE POWER SOURCE BEFORE PERFORMING ANY MAINTENANCE OR ADJUSTMENTS.
ADJUSTING THE THRUST BEARINGS
The thrust bearing keeps the blade from moving back and out of position when the saw arm pushes against the
workpiece. The thrust bearing must be very close to the back of the blade A to prevent damage to the blade during cutting. To adjust it, proceed as follows:
A
1. Shut off the hydraulic downfeed control valve and
lift the arm into the vertical position. Loosen screw B
on bracket C.
ADJUSTING THE BLADE GUARDS
The blade guards should be adjusted based the dimensions of the workpiece.
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 injuries, a
minimum amount of blade should be exposed.
For a straight cut and to reduce the risk of twisting, loosen lock knobs I & J and position the blade guards G &
H as close as possible to the workpiece, then retighten
the lock knobs.

Note: Forcing the blade into the workpiece increases
the risk of blade breakage and can affect the quality
of the cut (burrs, chips, etc.).
USING THE COOLANT PUMP
The switch D allows you to turn on or turn off the pump
of the coolant system. You can also stop the flow of the
liquid coolant by closing the tap E.
Make sure that the level of liquid coolant in the tank
located under the work table is between 3 liters (minimum) and 5 liters (maximum).
Don’t start the pump during vertical cuts.
Note: To reduce the risk of blade breakage and obtain cleaner cuts, it is recommended to turn on the
pump systematically when using the machine, excep for the vertical cuts.

A tension spring helps lift the arm into the the vertical
position and slows down its descent. If too little tension
makes it difficult to raise the arm, proceed as follow:
1. Loosen the jam nut B and tighten bolt C a few turns.
2. Repeat as needed until desired tension is achieved and then retighten the jam nut B.
Note: for less tension, loosen bolt C.

IMMOBILIZING THE MACHINE
Machine vibration during operation may cause the
machine to move, particularly when installed on uneven surfaces.
The bolt-down tab and anchor bolt A can be used to
help keep the machine immobilized by either lowering the bolt against the floor to act as another point of
contact with the floor, or for permanent installations, by
drilling into the floor and bolting the machine in place.

OPERATING INSTRUCTIONS
CHECKLIST BEFORE STARTING
VERIFY ALL CHECK POINTS BEFORE STARTING. FAILURE TO COMPLY CAN RESULT IN SERIOUS INJURIES.
1. Make sure you and any assistants are wearing safe and appropriate workshop attire.
2. To reduce the risk of damage to the machine, as well as 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 machine are locked in place before starting the machine.
3. Make sure to have on safety glasses as well as hearing or/and respiratory protection at all times when using the
machine.
4. Check the level of coolant in the tank and fill it as necessary. The level should be between 3 liters (minimum)
and 5 liters (maximum).
5. Use only recommended parts and accessories. The use of parts or accessories NOT recommended by
GENERAL® INTERNATIONAL may result in a risk of injury or damage to the machine.
6.
Be sure that adjusting wrenches, tools, drinks and other clutter are removed from the machine and/or the
table surface before operating.
OPERATIONS STEP-BY-STEP
NEVER USE THE SAW WITHOUT ALL GUARDS AND COVERS IN PLACE BEFORE STARTING THE SAW. BE SURE THAT THE
BLADE IS NOT ALREADY IN CONTACT WITH THE WORKPIECE.
For horizontal cuts
1. Raise the saw arm by the handle and lock it in position by shutting off the hydraulic downfeed control valve.
2. Trace the cutting line on your workpiece with a pencil and clamp the material firmly in the vise to ensure a
straight cut through the material. Make sure the workpiece is properly secured in the vise. Refer to the chart
below for proper stock placement in the vise.
Note: Use the work stop to make repeat cuts to the same length.
3. Adjust the blade guards as close as possible to the workpiece.
4. Start the machine.
5. Allow the blade to come to full speed, then begin the cut by opening the hydraulic downfeed control valve
and letting the head down slowly onto the workpiece. Re-adjust the cutting feed rate if needed.
Note: Do not drop or force the head onto the workpiece.
6. Wait for the automatic shutdown of the saw before carefully removing the workpiece from the vise.
BURN DANGER: DO NOT USE BARE HANDS TO TOUCH THE WORKPIECE AT THE CUT LOCATION UNTIL IT HAS COOLED.

OPERATIONS STEP-BY-STEP (CONTINUED)
NEVER USE THE SAW WITHOUT ALL GUARDS AND COVERS IN PLACE. BEFORE STARTING THE SAW BE SURE THAT THE
BLADE IS NOT ALREADY IN CONTACT WITH THE WORKPIECE.
For vertical cuts
1. Shut off the hydraulic downfeed control valve and lift the arm into the vertical position.
2. Make sure that the vertical table is securely installed so that it will adequately support the workpiece.
3. Adjust the blade guards as close as possible to the workpiece to minimize side-to-side blade movement.
4. Start the machine.
Note: Don’t turn on the coolant pump.
5. Slowly feed the workpiece into the blade by hand. Keep your fingers away from the blade and always hold
the workpiece securely against the table.
6. Stop the machine once finished.
MAINTENANCE
MAKE SURE THE MACHINE HAS BEEN TURNED OFF AND UNPLUGGED FROM THE POWER SOURCE BEFORE PERFORMING ANY MAINTENANCE OR ADJUSTMENTS.
CLEANING
Cleaning the bandsaw is relatively easy. After using your bandsaw, sweep up and discard any excess metal and
chips and debris. For optimum performance from your machine, follow this maintenance schedule and refer to
any specific instructions given in this section.
Daily:
• Check for loose mounting bolts
• Check the blade for damage
• Check for worn or damaged electrical wires
• Check for any other unsafe conditions
• Clean the metal blade brush
Monthly:
• Inspect V-belt tension, damage, or wear
• Clean the vise screw with air compressed as shown
and lubricate with an all-purpose oil.
LUBRICATION
1. Periodically clean the filter and the recovery tray. Fill the tank with coolant so that the level of liquid coolant is
between 3 and 5 liters.
2. Machine gears are mounted in an oil-bath. You
don’t need to fill it up, except in case of gear box
leak or overheating.
3. Change the oil once a year by replacing it with a
80W/90 oil as follows:
a. Remove bolts A with a 10 mm wrench and then
remove the gear box cover to drain the gear box.
b. Reinstall the cover and then remove plug B. Fill
the gear box with until it reaches the hole and then
retighten the plug B.

TIP: CHECK THE TENSION BY PUSHING GENTLY THE BELT
WITH YOUR FINGER. THE BELT SHOULD NOT MOVE MORE
THAN 1/2”.
1. Lower the arm into the horizontal position and loos-en the jam nut and bolt A with a 12 mm wrench.
2. Loosen jam nuts B and bolts C with a 12 mm wrench
until the motor base can be moved.
3. Open the pulley cover and change the belt.
Note: if there is not enough slack to move the belt,
loosen tension screws C as needed.
4. Place a straightedge on the two pulleys as shown D
to verify their alignment.
5. If the pulleys are not aligned, loosen the four bolts
E and F located on the motor mounting plate, and
then re-position the motor along the slotted mounting holes so that the pulleys are aligned.
6. With the pulleys aligned, retighten the four bolts E
and F.
7. Retighten the two bolts C alternating one turn at a time until the belt is tensioned properly. Then secure the motor in position by tightening the jam nuts B and the jam nut and bolt A.
8. Close the pulley cover.
