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 saw 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 saw is in operation; do not permit them to operate the saw.

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 and whenever possible use a dust collector and wear eye, ear and respiratory protection devices.

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 wrenches, tools, drinks and

other clutter are removed from the machine and/ or the feed table surface before operating.

9. Keep hands well away from the blade and all mov-

ing parts. Use a brush, not hands, to clear away chips and dust.

10. Be sure that the blade is securely installed and in

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.

Dirty or dull blades are unsafe and can lead to accidents.

13. If using a power feeder, stop the feeder before stop-

ping the table saw.

14. 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.

15. Use suitable support when cutting stock that does

not have a ﬂat surface. Always hold stock ﬁrmly against the fence when ripping, or against the miter gauge when cross cutting.

16. 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.

17. Avoid working from awkward or off balance posi-

tions. Do not overreach while cutting; keep both feet on ﬂoor. Never lean over or reach over the blade and never pull the workpiece over the blade from behind. Use out feed support or have an assistant help when ripping long material.

18. Keep blade 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 tool again.

19. Never leave the machine unattended while it is run-

ning or with the power on.

20. Use of parts and accessories NOT recommended

by GENERAL® INTERNATIONAL may result in equipment malfunction or risk of injury.

21. Never stand on machinery. Serious injury could re-

sult if the tool is tipped over or if the blade is unintentionally contacted.

22. Always disconnect tool from power before servic-

ing or changing accessories such as blades, or before performing any maintenance, cleaning or adjustments, or if the machine will be left unattended.

23. Make sure that switch is in “OFF” position before

plugging in the power cord.

24. Make sure the tool is properly grounded. If equipped

with a 3-prong plug it should be used with a threepole receptacle. Never remove the third prong.

25. Do not use this saw for any purpose other than its

intended use. If used for other purposes, GENERAL® INTERNATIONAL disclaims any real implied warranty and holds itself 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.

Note: voltage requirements and amperage draw for M2 & M3 3-phase motors 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.

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.

ELECTRICAL CONNECTIONS

Both a manual circuit breaker (or similar device) as well as an electrical plug are recommended and should be installed by a qualiﬁed electrician. Use locally approved wire that includes a separate grounding wire and a 3-prong grounding type plug A with a matching receptacle B .

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.

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. The smaller the number, the heavier the gauge.

The General International model 50-270 cabinet saw is available with various motor size and electrical voltage requirement options (see manual coverpage for complete list).

This cabinet saw has been designed for cutting solid wood as well as manufactured wood materials such as plywood, wood paneling, particleboard, mdf 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 saw is designed for use with maximum 10” (254 mm) diameter blades having a center hole diameter of 5/8”.

The blade can be raised to cut a maximum stock thickness of 3” with the blade set 90° to the table. The blade can be tilted up to 45° to the left for bevel cuts to a maximum stock thickness of 2 1/8”. Using any standard after market 8”diameter stacked dado blade set (not included), the maximum dado cutting capacity of this saw is 13/16”. Note: for safer dado cutting, an optional dado table insert (#50-302) can be purchased through your General International distributor.

To encourage safety through the proper use of either the supplied riving style splitter/blade guard assembly or the European style riving knife the 50-270 is designed with a quick install/quick release feature allowing the user to install or remove either of these safety components in seconds.

INSTALLATION

THIS MODEL 50-270 10” CABINET SAW 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 524 LBS (238 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 sander (524 lbs - 238 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 “nogo” 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.
