RULES FOR SAFE OPERATION
To help ensure safe operation, please take a moment to learn the machine’s applications and limitations, as well as potential hazards. General® International disclaims any real or implied warranty and holds itself harmless for any injury that may result from the improper use of it’s equipment.
1.Do not operate the bandsaw when tired, distracted or under the effects of drugs, alcohol or any medIcation that impairs reflexes or alertness.
2.The work 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 unsupervised use.
5.STAY ALERT! Give your work your undivided attention. Even a momentary distraction can lead to serious injury.
6.Fine particulate dust is a carcinogen that can be hazardous to health. Work in a well-ventilated area. Wear face, eye, ear, respiratory and body protection devices.
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 moving parts. Use a brush, not hands, to clear away chips and dust.
10.Adjust and position the blade guides before starting to cut.
11.Adjust blade tension and tracking before starting to cut.
12.Blade 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.Make sure the workpiece is securely held in place in the vise.
17.Do not work on long stock without adequate support on the out feed end of the table.
18.Do not push or force stock into the blade. The bandsaw will perform better and more safely when working at the rate for which it was designed.
19.Avoid working from awkward or off balance positions. Do not overreach and keep both feet on floor.
20.Keep guards in place and in working order. If a guard must be removed for maintenance or cleaning be sure it is properly re-attached before using the saw again.
21.Never leave the machine unattended while it is run-- ning or with the power on.
22.Use of parts and accessories NOT recommended by General® International may result in equipment malfunction or risk of injury.
23.Never stand on machinery. Serious injury could result if the tool is tipped over or if the cutting tool is unintentionally contacted.
24.Always disconnect the saw from the power source before servicing or changing accessories such as blades, or before performing any maintenance or cleaning, or if the machine will be left unattended.
25.Make sure that the switch is in the “OFF” position before plugging in the power cord.
26.Make sure the machine is properly grounded. If equipped with a 3-prong plug it should be used with a three-pole receptacle. Never remove the third prong.
27.Donotusethisbandsawforotherthanitsintendeduse. If used for other purposes, General® International disclaims any real or implied warranty and holds it self harmless for any injury, which may result from that use.

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.

B C
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.
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.

BASIC FUNCTIONS
This 7” x 12” horizontal metal cutting band saw is designed for both vertical and horizontal cutting in metalworking and machine shops for cutting various types of bar stock, channel stock, piping, and thin-walled tubing.
With three blade speeds to accommodate a wide range of cutting needs, the unit features an automatic hydraulically controlled down feed with auto shutoff 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 MODEL 90-700 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.
