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 harmless for any injury that may result from the improper use of its equipment.

1. Do not operate the saw when tired, distracted, or un der 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 saw is in operation; do not permit them to ope rate the saw.

4. Childproof and tamper proof your shop and all ma chinery 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 and whenever possible use a dust collector and wear eye, ear and respiratory protection devices.

International disclaims any real or implied warranty and holds itself

13. Do not push or force stock into the blade. The saw will perform better and more safely when working at the rate for which it was designed.

14. To minimize risk of injury in the event of workpiece kickback, never stand directly in-line with the blade or in the potential kickback path of the workpiece.

15. Avoid working from awkward or off balance posi tions. Do not overreach while cutting; keep both feet on ﬂoor. Use outfeed support or have an assistant help when cutting long material.

16. Keep blade guards in place and in working or der. If a guard must be removed for maintenance or cleaning, be sure it is properly re-attached before using the tool again.

17. Never leave the machine running with the power on when not in operation.

18. Use of parts and accessories NOT recommended by General malfunction or risk of injury.

International may result in equipment

7. Do not wear loose clothing, gloves, bracelets, neck laces or other jewelry while the saw is in operation. Wear protective hair covering to contain long hair and wear non-slip footwear.

8. Be sure that adjusting wren ches, 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. Be sure that the blade is securely installed and in the proper cutting direction before operation.

11. Be sure the blade has gained full operating speed before beginning to cut.

12. Always use a clean, properly sharpened blade. Dir ty or dull blades are unsafe and can lead to accidents.

19. Never stand on machinery. Serious injury could result if the tool is tipped over or if the blade is unin tentionally contacted.

20. Always disconnect tool from power before servicing or changing accessories such as blades, or before performing any maintenance, cleaning or adjust ments, or if the machine will be left unattended.

21. Make sure that switch is in ”OFF” position before plug ging in the power cord.

22. Make sure the tool is properly grounded. If equip ped with a 3-prong plug it should be used with a

three-pole receptacle. Never remove the third prong.

23. Do not use this saw for any purpose other than its intended use. If used for other purposes, General® International disclaims any real or im plied warranty and holds itself harmless for any in jury, 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.

Note: Voltage requirements and amperage draw for M2 3-phase motor may not be fully described in this manual. For complete electrical requirements refer to the motor I.D. name plate on the machine. If in doubt consult a licensed qualiﬁed electrician before proceeding.

ELECTRICAL CONNECTIONS

Both a manual circuit breaker (or similar device) as well as an electrical plug (similar to the one shown) are recommended and SHOULD BE INSTALLED BY A QUALIFIED ELECTRICIAN.

Use locally approved wire A that includes a separate grounding wire and a 3 prong grounding type plug B with a matching receptacle C.

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 the ”M1” model of this machine is wired for 220 V single phase operation. As with many stationary industrial type machines, because each installation situation is unique, this machine is supplied without a power cord or plug. The installation of an appropriate power cord and plug must be performed by a qualiﬁed electrician. The machine must be connected to an electrical source using a power cord that has a grounding wire, which must also be properly connected to the grounding prong on the plug. The outlet must be properly installed and grounded and all electrical connections must be made in accordance with all local codes and regulations.

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 220 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. 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.

BASIC FUNCTIONS

This 16” radial arm saw is designed for multipurpose cutting of solid wood, as well as manufactured wood materials and other wood based by-products. This saw is not designed for cutting metals nor for cutting any materials other than wood or wood based stock.

This versatile unit offers a crosscutting capacity of 24” and uses maximum 16" (406 mm) diameter blades having a center hole bore diameter of 1". The maximum stock thickness cutting capacity of this saw is 4 7/8” with the blade set 90 degrees to the table. The blade can be tilted up to 45 degrees for bevel cuts to a maximum stock thickness of 2 1/2". The 50-760 is also designed to perform miter cuts and compound (beveled) miters and has a dado cutting capacity of 1”.

PLACEMENT WITHIN THE SHOP / SAFETY ZONE

THIS RADIAL ARM SAW MODEL 50-760 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 572 LBS (260 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 (572 lbs - 260 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.
