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.

GROUNDING INSTRUCTIONS

In the event of an electrical malfunction or short circuit, grounding reduces the risk of electric shock to the operator.

The motor of this machine is wired for 240 V single phase operation and is equipped with a 3-conductor cord A and a 3-prong grounded plug B to fit a matching grounding type receptacle C.

DO NOT MODIFY THE PLUG PROVIDED! If it will not ﬁt your receptacle, have the proper receptacle installed by a qualiﬁed electrician.

CHECK with a qualified electrician or service person if you do not completely understand these grounding instructions, or if you are not sure the tool is properly grounded.

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.

EXTENSION CORDS

The use of an extension cord is not generally recommended for 240 V equipment. If you find it necessary, 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.

If you find it necessary to use an extension cord with your machine 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.

BASIC FUNCTIONS

This 9” x 16” horizontal metal cutting band saw is designed for horizontal cutting in metalworking and machine shops for cutting various types of bar stock, channel stock, piping, and thin-walled tubing.

With four blade speeds to accommodate a wide range of cutting needs, the unit features an automatic hydraulically controlled down feed with auto shut off at the end of the cutting cycle.

The coolant system with built-in pump is designed to supply a continuous ﬂow of liquid coolant to the cutting area to prevent overheating of both the blade and the workpiece, providing cleaner cuts and prolonging blade life.

PLACEMENT WITHIN THE SHOP / SAFETY ZONE

THIS METAL CUTTING BANDSAW 90-790 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 543 LBS (247 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 (543 lbs - 247 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.

BASIC ADJUSTMENTS & CONTROLS

TO REDUCE THE RISK OF SHOCK OR FIRE DO NOT OPERATE THE UNIT WITH A DAMAGED POWER CORD OR PLUG. REPLACE DAMAGED CORD OR PLUG IMMEDIATELY. TO AVOID UNEXPECTED OR UNINTENTIONAL START-UP, MAKE SURE THE POWER SWITCH IS IN THE OFF POSITION BEFORE CONNECTING TO A POWER SOURCE.

CONNECTING TO A POWER SOURCE

Once the assembly steps have been completed, plug the power cord into an appropriate outlet.

Refer back to the section entitled “Electrical Require ments” and make sure all requirements and grounding instructions are followed.

When operations have been completed unplug the saw from the power source.

MAIN ON/OFF MAGNETIC SWITCH

This machine is equipped with a magnetic safety switch designed to protect the unit and the user from power surges, power outages and unwanted or unintentional start-up.

The switch assembly is equipped with a safety lock-out switch with removable key E, a green “start” button F, a red “stop” button with twist lock-out feature D. Once the button D has been pressed, the machine can only be started by turning the inner part of the button D to the right to release the stop button.

The limit switch H is designed to make contact with the stop bolt I and turn off the machine when the cut is completed. If necessary the stop bolt I can be adjusted by loosening the jam nut J and adjusting the bolt height I and then retightening the jam nut to secure the bolt in place J.

The switch G allows you to turn the coolant system pump on or off. To start the pump, turn the switch to the right. To stop the pump, turn the switch to the left.

The power light indicator C indicates that the machine is connected to the power source.

SWITCH OFF

TO AVOID UNEXPECTED OR UNINTENTIONAL START-UP, MAKE SURE THAT THE POWER SWITCH IS IN THE OFF POSITION BEFORE CONNECTING TO A POWER SOURCE.

MAKE SURE THE MACHINE HAS BEEN TURNED OFF AND UNPLUGGED FROM THE POWER SOURCE BEFORE PERFORMING ANY MAINTENANCE OR ADJUSTMENTS.

OVERLOAD PROTECTION

The magnetic safety switch on this machine is equipped with an overload protection feature. To prevent an electrical 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 cutting at a feed speed that is too agressive, 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 increase 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:

Loosen the cap screw A with a 5 mm Allen key and open the access door. Press the button B to reset the overload protection switch. Close the access door and retighten the cap screw A before restarting the machine.

Note: If the machine still does not work after resetting the overload protector, check the fuses C and replace them if necessary with identical ones (replacement fuses are provided).

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 0.032” (0,9 mm) thickness and 1” (27 mm) widths, based on what is available in your area. Ideal blade length for model 90-790 is 119” (3035 mm).

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.

1. To lock the blade arm in the up position shut off the hydraulic valve D by turning it all the way clockwise.

2. Raise the arm a little as shown E.

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 setting with various blade widths.

To adjust the blade tension:

1. Lower the arm into the horizontal position.

2. Turn the handwheel A clockwise to tension the

blade or counterclockwise to loosen. The blade tension shoud be about 20,000 psi (1400 kg/cm²). Use the tension indicator B with its graduated scale

in kg/cm².

3. Make a test cut on a sample piece and if needed,

re-adjust the blade tension.

ADJUSTING BLADE TRACKING

The front wheel of the machine is aligned at the factory, but it may be necessary to adjust the alignment after a long period of use or after an important maintenance operation. This potential misalignment can be corrected by adjusting the tilt of the front wheel.

1. Shut off the hydraulic downfeed control valve by

turning it all the way clockwise then lift the arm into the highest position C.

2. Open the blade covers D.

ING ANY MAINTENANCE OR ADJUSTMENTS.

ADJUSTING THE BLADE GUARD

The blade guard should be adjusted based on the dimensions of the workpiece. To prevent the blade (which is ﬂexible and which would not otherwise be supported) from slipping out of position when cutting, and to reduce the risk of injury, a minimum amount of blade should be exposed. For a straight cut and to reduce the risk of twisting, loosen lock lever A and position the blade guard as close as possible to the workpiece, then retighten the lock lever.

Note: the graduated scale B can be used as a reference when positionning the guard.

CHANGING SPEEDS

Note: The help from an assistant is recommended.

1. Loosen without removing the bolt C located under

the motor with a 14 mm wrench in order to loosen the belt.

2. Open the pulley cover and position the belt on the

pulleys based on the desired blade speed (refer to the chart below).

3. Pull the motor back towards you while tightening the lock bolt C and then close and lock the pulley cover.

CUTTING FEED RATE/ SAW ARM TENSION

- Turn the knob A clockwise to increase the cutting

feed rate.

- Turn the knob A counterclockwise to decrease 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.).

USING THE COOLANT PUMP

OFF

The switch D allows you to turn the pump on or off.

FILLING THE COOLANT TANK

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.

CLOSED

You can stop the ﬂow of liquid coolant by closing the two valves E.

Lift the recovery tray F to access and ﬁll the coolant tank with up to17 liters max of coolant.

Note: To prolong pump life and prevent blockages in the coolant system, clean the filter G regularly using a compressed air blow gun to remove metal chips and other debris.

Note: Gauge H indicates coolant level. Remove the plug I to drain the tank when necessary. Do not block the coolant overflow vent J.

MAKE SURE THE MACHINE HAS BEEN TURNED OFF AND UNPLUGGED FROM THE POWER SOURCE BEFORE PERFORMING ANY MAINTENANCE OR ADJUSTMENTS.

SECURING AND LEVELING THE MACHINE

Machine vibration during operation may cause the machine to move, particularly when installed on uneven surfaces.

The bolt-down tabs and anchor bolts A can be used to help keep the machine immobilized by either lowering the bolts 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 coolant level in the tank and ﬁll it as necessary. The level should be between 5 liters (minimum) and

17 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.

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.

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 quickly and accurately cut multiple pieces of stock to the same length.

3. Adjust the blade guards as close as possible to the workpiece.

4. Start the machine. Allow the blade to come to full speed, then begin the cut by opening the hydraulic downfeed

control valve and letting the arm down slowly onto the workpiece. Re-adjust the feed rate if needed.

Note: Do not drop or force the head onto the workpiece.

5. 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.

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 compressed air as shown and lubricate with an all-purpose oil.

LUBRICATION

1. 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 ISO VG 150 gear oil as follows:

a. Remove plug A with a 6 mm Allen key to drain

the gear box.

b. Re-install plug A and then remove plug B. Fill the

gear box until it reaches the hole and then re-install plug B.

2. This machine is equipped with two grease ﬁttings C and D to facilitate lubrication of the shaft arm.

It is recommended to lubricate with an all-purpose grease, once a week if you use the machine daily.
