ADDITIONAL SAFETY RULES FOR

SCROLL SAWS

WARNING: FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS PERSONAL INJURY.

1.DO NOT OPERATE your scroll saw until it is completely assembled and installed according to the instructions.

2.IF YOU ARE NOT thoroughly familiar with the operation of Scroll Saws, obtain advice from your supervisor, instructor or other qualified person.

3.YOUR SCROLL SAW MUST be securely fastened to a stand or workbench. If there is any tendency for the stand or workbench to move during operation, the stand or workbenchMUST be fastened to the floor.

4.THIS SCROLL SAW is intended for indoor use only.

5.MAKE SURE blade is properly tensioned before operating saw.

6.TO AVOID blade breakageALWAYS adjust blade tension correctly.

7.MAKE SURE the blade teeth point downward toward the table.

21.NEVER start the Scroll Saw with the stock pressed against the blade.

22.WHEN cutting a large workpieceMAKE SURE the material is supported at table height.

23.USE CAUTION when cutting material which is irregular in cross section which could pinch the blade before the cut is completed. A piece of moulding for example must lay flat on the table and not be permitted to rock while being cut.

24.USE CAUTION when cutting round material such as dowel rods or tubing. They have a tendency to roll while being cut causing the blade to "bite." Use aV-blockto control the piece.

25.ALWAYS release blade tension before removing the blade from the upper or lower blade holders.

26.MAKE CERTAIN table tilting lock is tightened before starting the machine.

8.NEVER turn the saw"ON" before clearing the table of all objects (tools, scraps of wood, etc.).

9.DO NOT cut material that is too small to be safely supported.

10.AVOID awkward hand positions where a sudden slip could cause a hand to move into the blade.

11.ALWAYS keep hands and fingers away from blade.

12.ALWAYS adjust holddown foot for each new operation.

13.DO NOT USE dull or bent blades.

14.DO NOT attempt to saw material that does not have a flat surface, unless a suitable support is used.

15.MAKE "relief" cuts before cutting long curves.

16.NEVER attempt to cut a curve that is too tight for the blade being used.

17.WHEN backing a blade out of a workpiece, the blade may bind in the saw kerf. This is usually caused by sawdust in the kerf. If this happens, turn"OFF" the switch and remove plug from power source outlet. Wedge open the kerf and back blade out of the workpiece.

18.THE USE of attachments and accessories not recommended by Delta may result in the risk of injuries.

19.ALWAYS hold the work firmly against the table.

20.DO NOT feed the material too fast while cutting. Only feed the material fast enough so that the blade will cut.

27.NEVER reach under the table while the machine is running.

28.NEVER perform layout, assembly orset-upwork on the table while the saw is operating.

29.ALWAYS STOP the saw before removing scrap pieces from the table.

30.WHEN THE TOOL IS NOT IN USE, the switch should be locked in the “OFF”position to prevent unauthorized use.

31.SHOULD any part of your Scroll Saw be missing, damaged or fail in any way, or any electrical component fail to perform properly, shut off switch and remove plug from power supply outlet. Replace missing, damaged or failed parts before resuming operation.

32.ADDITIONAL INFORMATION regarding the safe and proper operation of this product is available from the National Safety Council, 1121 Spring Lake Drive, Itasca, IL 60143-3201, in the Accident Prevention Manual for Industrial Operations and also in the Safety Data Sheets provided by the NSC.

POWER CONNECTIONS

A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wireextension cords which have 3- prong grounding type plugs and matching receptacle which will accept the machine’s plug. Before connecting the motor to the power line, make sure the switch is in the “OFF” position and be sure that the electric current is of the same characteristics as indicated on the machine. All line connections should make good contact. Running on low voltage will damage the motor.

WARNING: DO NOT EXPOSE THE MACHINE TO RAIN OR OPERATE THE MACHINE IN DAMP LOCATIONS.

MOTOR SPECIFICATIONS

Your machine is wired for 120 volt, 60 HZ alternating current. Before connecting the machine to the power source, make sure the switch is in the “OFF” position.

GROUNDING INSTRUCTIONS

WARNING: THIS MACHINE MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM ELECTRIC SHOCK.

1. All grounded, cord-connectedmachines:

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This machine is equipped with an electric cord having an equipmentgrounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician.

Improper connection of the equipment-groundingconductor can result in risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipmentgrounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect theequipment-groundingconductor to a live terminal.

Check with a qualified electrician or service personnel if t h e g ro u n d i n g i n s t r u c t i o n s a re n o t c o m p l e t e l y understood, or if in doubt as to whether the machine is properly grounded.

Use only 3-wireextension cords that have3-pronggrounding type plugs and matching3-conductorreceptacles that accept the machine’s plug, as shown in Fig. A.

Repair or replace damaged or worn cord immediately.

2. Grounded, cord-connectedmachines intended for use on a supply circuit having a nominal rating less than 150 volts:

If the machine is intended for use on a circuit that has an outlet that looks like the one illustrated in Fig. A, the machine will have a grounding plug that looks like the plug illustrated in Fig. A. A temporary adapter, which looks like the adapter illustrated in Fig. B, may be used to connect this plug to a matching 2-conductorreceptacle as shown in Fig. B if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. Thegreen-coloredrigid ear, lug, and the like, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box. Whenever the adapter is used, it must be held in place with a metal screw.

NOTE: In Canada, the use of a temporary adapter is not permitted by the Canadian Electric Code.

WARNING: IN ALL CASES, MAKE CERTAIN THE RECEPTACLE IN QUESTION IS PROPERLY G R O U N D E D . I F Y O U A R E N O T S U R E H AV E A

EXTENSION CORDS

Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wireextension cord which has a3-pronggrounding type plug and matching receptacle which will accept the machine’s plug. When using an extension cord, be sure to use one heavy enough to carry the current of the machine. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Fig. D, shows the correct gauge to use depending on the cord length. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.
