Safety Instructions For Power Tools

SECTION 1: SAFETY

5. KEEP CHILDREN AND VISITORS AWAY. All children and visitors should be

kept a safe distance from work area.

6. MAKE WORKSHOP CHILD PROOF with

padlocks, master switches, or by removing starter keys.

7. DO NOT FORCE TOOL. It will do the job

better and safer at the rate for which it was designed.

8. USE RIGHT TOOL. Do not force tool or

attachment to do a job for which it was not designed.

1. KEEP GUARDS IN PLACE and in working

order.

2. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to

see that keys and adjusting wrenches are removed from tool before turning on.

3. KEEP WORK AREA CLEAN. Cluttered

areas and benches invite accidents.

4. DO NOT USE IN DANGEROUS ENVIRONMENT. Don’t use power tools in

damp or wet locations, or where any flammable or noxious fumes may exist. Keep work area well lighted.

For Your Own Safety Read Instruction

Manual Before Operating This Equipment

Indicates an imminently hazardous situation which, if not avoided, WILL result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided, COULD result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided, MAY result in minor or moderate injury. It may also be used to alert against unsafe practices.

This symbol is used to alert the user to useful information about proper operation of the equipment.

The purpose of safety symbols is to attract your attention to possible hazardous conditions. This manual uses a series of symbols and signal words which are intended to convey the level of importance of the safety messages. The progression of symbols is described below. Remember that safety messages by themselves do not eliminate danger and are not a substitute for proper accident prevention measures.

9. USE PROPER EXTENSION CORD. Make

sure your extension cord is in good condition. Conductor size should be in accordance with the chart below. The amperage rating should be listed on the motor or tool nameplate. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Your extension cord must also contain a ground wire and plug pin. Always repair or replace extension cords if they become damaged.

Minimum Gauge for Extension Cords

10. WEAR PROPER APPAREL. Do not wear

loose clothing, gloves, neckties, rings, bracelets, or other jewelry which may get caught in moving parts. Non-slip footwear is recommended. Wear protective hair covering to contain long hair.

11. ALWAYS USE SAFETY GLASSES. Also

use face or dust mask if cutting operation is dusty. Everyday eyeglasses only have impact resistant lenses, they are NOT safety glasses.

12. SECURE WORK.Use clamps or a vise to hold

work when practical. It’s safer than using your hand and frees both hands to operate tool.

13. DO NOT OVERREACH. Keep proper foot-

ing and balance at all times.

14. MAINTAIN TOOLS WITH CARE. Keep

tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories.

15. USE RECOMMENDED ACCESSORIES.

Consult the owner’s manual for recommended accessories. The use of improper accessories may cause risk of injury.

Safety Instructions For Power Tools

16. REDUCE THE RISK OF UNINTENTIONAL STARTING. On machines with mag-

netic contact starting switches there is a risk of starting if the machine is bumped or jarred. Always disconnect from power source before adjusting or servicing. Make sure switch is in OFF position before reconnecting.

17. MANY WOODWORKING TOOLS CAN “KICKBACK” THE WORKPIECE toward

the operator if not handled properly. Know what conditions can create “kickback” and know how to avoid them. Read the manual accompanying the machine thoroughly.

18. CHECK DAMAGED PARTS. Before fur-

ther use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced.

19. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Do not

leave tool until it comes to a complete stop.

20. NEVER OPERATE A MACHINE WHEN TIRED, OR UNDER THE INFLUENCE OF DRUGS OR ALCOHOL. Full mental alert-

ness is required at all times when running a machine.

21. NEVER ALLOW UNSUPERVISED OR INEXPERIENCED PERSONEL TO OPERATE THE MACHINE. Make sure

any instructions you give in regards to machine operation are approved, correct, safe, and clearly understood.

22. IF AT ANY TIME YOU ARE EXPERIENCING DIFFICULTIES performing the intend-

ed operation, stop using the machine! Then contact our service department or ask a qualified expert how the operation should be performed.

No list of safety guidelines can be complete. Every shop environment is different. Always consider safety first, as it applies to your individual working conditions. Use this and other machinery with caution and respect. Failure to do so could result in serious personal injury, damage to equipment or poor work results.

Additional Safety Instructions For The Lathe

1. MAKE SURE ALL GUARDS are in place

and that the Lathe sits on a flat, stable surface.

2. ALWAYS WEAR EYE PROTECTION or a

face shield when operating the Lathe. Use a respirator to avoid inhaling dust. All safety equipment should be ANSI approved.

3. BEFORE STARTING THE MACHINE be

certain the workpiece has been properly imbedded on the headstock and tailstock centers and that there is adequate clearance for the full rotation.

4. ADJUST TOOL REST to provide proper

support for the turning tool you will be using. Test tool rest clearance by rotating workpiece by hand before turning lathe on.

5. SELECT THE TURNING SPEED which is

appropriate for the type of work. Allow the lathe to gain its full speed before using the lathe.

6. ALWAYS INSPECT THE CONDITION of

the materials you are turning. Pay particular attention to knots, splits and other potentially dangerous conditions.

7. KEEP LATHE TOOLS PROPERLY SHARPENED and hold firmly in the proper

position when turning.

8. NEVER OPERATE THE LATHE WITH DAMAGED OR WORN PARTS. Maintain

your lathe in proper working condition. Perform routine inspections and maintenance promptly when called for. Put away adjustment tools after use.

9. MAKE SURE YOUR WOOD LATHE IS TURNED OFF, disconnected from its power

source and all moving parts have come to a complete stop before starting any inspection, adjustment, or maintenance procedure.

10. DO NOT LEAVE LATHE RUNNING UNATTENDED for any reason.

11. DO NOT STOP LATHE USING YOUR HAND against the workpiece.

12. KEEP LOOSE CLOTHING ARTICLES

such as sleeves, belts or jewelry items away from the lathe spindle.

13. WHEN FACE PLATE TURNING, use lathe

chisels on the downward spinning side of the workpiece only.

14. REMOVE THE TOOL REST when perform-

ing sanding or polishing operations on the rotating spindle.

15. ATTEMPTING TO REMOVE too much

material at once may cause work material to fly out of the lathe.

110V Operation

SECTION 2: CIRCUIT REQUIREMENTS

The lathe comes equipped with its own fuse rated at 3.15 amps. Never replace the fuse with one rated higher than 3.5 amps.

If you find it necessary to use an extension cord with the Model G8690, make sure the cord is rated Hard Service (grade S) or better. Refer to the chart in the standard safety instructions to determine the minimum gauge for the extension cord. The extension cord must also contain a ground wire and plug pin. Always repair or replace extension cords when they become worn or damaged.

Extension Cords

Grounding

In the event of an electrical short, grounding reduces the risk of electric shock by providing a path of least resistance to disperse electric current. This tool is equipped with a power cord having an equipment-grounding conductor. See

Figure 1. The outlet must be properly installed

and grounded in accordance with all local codes and ordinances.

The Model G8690 is wired for 110/120V, singlephase operation only. The

⁄3 HP motor will safely draw 3.1 amps at 110V. If you operate this machine on any circuit that is already close to its capacity, it might blow a fuse or trip a circuit breaker. However, if an unusual load does not exist and a power failure still occurs, contact a qualified electrician or our service department.

This equipment must be grounded. Verify that any existing electrical outlet and circuit you intend to plug into is actually grounded. Under no circumstances should the grounding pin from any three-pronged plug be removed. Serious injury may occur.
