ELECTRICALREQUIREMENTS
6
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.
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 opera-
tion and is equipped with a 3-conductor cord and a
3-prong grounding plug Ato fit a grounded type recep-
tacle 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 out-
let, 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.
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 appro-
priate 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 elec-
trician. 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 per-
sonal 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 recep-
tacle 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 over-
heating. 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.

OVERLOAD PROTECTION
Loosen the bolt Awith a 10 mm wrench and open the overload protection access door. Press on the button Bto
reset the overload protection switch. Close the overload protection access door and retighten bolt Abefore re-
starting the machine.
Note: If the machine still does not work after resetting the overload protector, check all three fuses located inside the
electrical box and replace them as needed with matching amperage fuses.
AB
The magnetic safety switch on this machine is equipped with an overload protection feature. To prevent an elec-
trical overload from damaging the motor, in the event of a spike in line voltage or amperage draw, the internal
overload protector will automatically be tripped, thereby cutting off power to the motor.
Common causes of such overloads:
1. Overworking the motor by attempting to remove too much material in one single pass or by feeding the work-
piece too quickly, thereby causing an increase in power consumption and a spike in amperage draw.
2. An electrical extension cord that is too long or not the correct gauge of wire, which can also cause an in-
crease in amperage draw. If an electric extension cord must be used, follow the instructions and refer to the
chart in the electrical requirements section at the beginning of this manual.
3. Overworked circuit caused by operating on a circuit that is close to its amperage draw capacity. Make sure
the circuit being used is capable of handling the amperage draw from this machine as well as any other
electrical devices operating on the same circuit. If you are unsure, consult a qualified electrician.
To reset the overload protection switch after it has been tripped proceed as follows:
CHANGING THE 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.
The blades with fewer teeth per inch are best suited to cut quickly and aggressively but do have a tendency to
bind (or get stuck in the cut) if turned too sharply. Thinner blades with more teeth per inch will cut more slowly but
can cut with more precision.
Common causes of blade breakage:
• Poor blade guide or support bearing alignment and
adjustment.
• Dull teeth.
• Setting blade guard assembly too far from the work-
piece.
• Too much blade tension.
• Lumpy or improperly finished braze or weld on the
blade.
• Cutting feed rate too high.

6. Re-install the metal brush positioning it along its
elongated mounting holes C, and close the blade
cover.
5. Install a new blade with the teeth towards you. To ten-
sion the blade, hold the blade against the shoulder

ADJUSTING BLADE TENSION
A properly tensioned blade is critical to obtaining maximum performance from any bandsaw. A properly ten-
sioned 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 pre-
maturely.
The following information can be used as a guideline or starting point to assist you in determining ideal blade ten-
sion. 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 Aclockwise to ten-
sion the blade or counterclockwise to
loosen. The white mark Bshoud be cen-
tered in the shaded zone Cof the ten-
sion 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”.

The guide bearings Kkeep 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 the 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.

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 dur-
ing cutting. To adjust it, proceed as follows:
ADJUSTING THE THRUST BEARINGS
1. Shut off the hydraulic downfeed control valve and
lift the arm into the vertical position. Loosen screw B
on bracket C.
2. Push bracket Cas shown Duntil the thrust bearing
touches the back of the blade A. Repeat for the
other thrust bearing.
Note: The blade guides must remain at least 1/32” behind
the blade teeth to prevent damage to the blade as shown E.
MAKE SURE THE MACHINE HAS BEEN TURNED OFF AND UNPLUGGED FROM THE POWER SOURCE BEFORE PERFORM-
ING ANY MAINTENANCE OR ADJUSTMENTS.
The blade guards should be adjusted based the di-
mensions of the workpiece.
To prevent the blade (which is flexible and which would
not otherwise be supported) from slipping out of po-
sition 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, loos-

CUTTING FEED RATE/ SAW ARM TENSION
A hydraulic cylinder allows adjustments to the downfeed speed of the arm to control cutting speed.
Note: The valve must be open in order to adjust the cutting feed rate.
- Turn the knob Aclockwise to increase the cutting
feed rate.
- Turn the knob Acounterclockwise to reduce the
cutting feed rate.
Note: Forcing the blade into the workpiece increases the
risk of blade breakage and can affect the quality of the cut
(burrs, chips, etc.).
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 Band tighten bolt Ca few turns.
2. Repeat as needed until the desired tension is
achieved and then retighten the jam nut B.

The bolt-down tab and anchor bolt Acan be used to
help keep the machine immobilized by either lower-
ing 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.

VERIFY ALL CHECK POINTS BEFORE STARTING. FAILURE TO COMPLY CAN RESULT IN SERIOUS INJURIES.
CHECKLIST BEFORE STARTING
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.
OPERATINGINSTRUCTIONS
BURN DANGER: DO NOT USE BARE HANDS TO TOUCH THE WORKPIECE AT THE CUT LOCATION UNTIL IT HAS COOLED.
OPERATIONS STEP-BY-STEP
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 workpiece 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.
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.

MAKE SURE THE MACHINE HAS BEEN TURNED OFF AND UNPLUGGED FROM THE POWER SOURCE BEFORE PERFORM-
ING ANY MAINTENANCE OR ADJUSTMENTS.
LUBRICATION
Periodically clean the filter and the recovery tray. Fill
the tank so that the liquid coolant level is between 3
and 5 liters. 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.
Change the oil once a year by replacing it with a
80W/90 oil as follows:
1. Remove bolts Awith a 10 mm wrench and then re-
move the gear box cover to drain the gear box.
2. Re-install the cover and then remove plug B. Fill the
gear box with until it reaches the hole and then re-
install the plug B.

MAINTENANCE
CLEANING
After using your bandsaw, sweep up and discard any
excess metal chips and debris. 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 compressed air and lubri-
cate as shown with an all-purpose oil.
1. Lower the arm into the horizontal position and loosen the jam nut and bolt Awith a 12 mm wrench.
2. Loosen jam nuts Band bolts Cwith 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 bolts C as needed.
4. Place a straight edge on the two pulleys to verify their alignment. If the pulleys are not aligned, loosen the four
bolts Dand Elocated on the motor mounting plate, and then reposition the motor along the slotted mounting
holes so that the pulleys are aligned.
5. With the pulleys aligned, retighten the four bolts Dand E.
6. Retighten the two bolts Calternating one turn at a time until the belt is tensioned properly. Then secure the
motor in position by tightening the jam nuts Band the jam nut and bolt A. Close the pulley cover.
Note: check the tension by pushing the belt with your finger. The belt should not move more than 1/2”.
