Compound Miter Saw Safety

Specific safety instructions for this compound miter saw:

1. Do not operate the miter saw until it is completely assembled and installed according to these instructions.

2. If you are not thoroughly familiar with the operation of miter saws, seek guidance from your supervisor, instructor or other qualified person.

3. Always hold the work firmly against the fence and t able.

4. Do not perform any operat ion free hand (use clamp wherev er possible).

5. Keep hands out of the path of the saw blade. If the workpiece you are cutting would cau se your hands to be within 6-3/4 in. of the saw blade, the workpiece should be clamped in place before making the cut.

6. Be sure the blade is sharp, runs f r eely and is free of vibration.

7. Allow the motor to com e up to full speed before starting a cut.

8. Keep the motor air slot s clean and free of chips or dust.

9. Always make sure all handl es are tight before c utting, ev en if the table is positi oned in one of the positive stops.

10. B e sure both the blade and the coll ar are clean and the arbor bolt is tightened securely.

11. Use onl y blade collars specified for your saw.

12. Never use blades larger in diam eter than 10 inches.

13. Never apply lubricants to the blade when it is running.

14. A lways check the blade for crack s or damage before operation. Replace a crac k ed or dam aged blade immediately.

15. Never use blades recommended for operation at less than 4800 RPM.

16. A lways keep the blade guards in place and use at all times.

17. Never reach around the saw blade.

18. M ak e sure the blade is not contacting the workpiece bef or e the switc h is tur ned ON.

19. Impor tant : Aft er com pleting t he cut , rel ease the t ri gger and wait for the bl ade to stop before ret urni ng the saw to the raised position.

20. Make sure the blade has come to a complete stop before removing or securing the workpiece, changing the workpi ec e angle or changing the angle of the blade.

21. Nev er cut metal s or masonry product s wit h thi s tool . Thi s mit er saw is designed for use on wood and wood-lik e pr oduc ts.

22. Never cut small pieces. If the workpiec e being cut would cause your hand or fingers to be within 6- 3/4 in. of the saw blade the workpiece is too small.

23. P r ovide adequate support t o the sides of the saw table for long work pieces.

24. Never use the miter saw in an area with flammable liquids or gases.

25. Never use solvents to c lean p lastic pa rts. S o lvents cou ld po s s ibly dissolve o r o therw ise da mage the mater ial.

Electrical

Extens ion Cords

Power Supply and Motor Specifications

The AC motor used in this saw is a universal, nonreversible type (see Motor in the Specifica- tions section on page 7).

To avoid electrical hazards, fire hazards, or damage to the machine, use proper circuit protection. Your saw is wired at the facto ry for 120V operati on. Conn ect to a 120V, 15 Amp circui t and use a 15 amp time delay fuse o r circu it breaker. If power co rd is worn or cut, or damaged in any way, have i t replaced immediately to avoid shock or fire.

Electrical Requirements

This machine is double insulated to provide a double thickness of insulation between the user and the machine's electrical system. A ll exposed metal part s are isolat ed from the inter nal metal motor component s with pr otective insulati on.

This saw has a plug that looks like the one shown in Figure A.

Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your m achine will dr aw. An undersized cord will cause a drop in the line voltage resulting in power loss and overheating. The table below shows the correct size to use depending on the cord length and nameplate ampere rati ng. If in doubt, use the next heavier gauge. Remember, the smaller the gauge number, the heavier the cord.

Cord Length AWG 00 – 25ft 016 25 – 50ft 014

Important: Make certain the receptacle in question is properly grounded. If you are not sure, have a registered electrician check the receptacle.

Figure A

To reduce the risk of electrical shock, this saw has a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way; if the plug does not fit fully in the outlet, reverse the pl ug. If it still does not fit , contact a qualified electrician to install the proper outlet. Do not change the plug i n any way.

Double insulation does not take the place of normal safety precautions when operating this tool.

To avoid electroc ution:

1. Use only identical replacement parts when

servicing a tool with double insulation. Servicing shoul d be per formed by a qualified technician.

2. Do not use power tools in wet or damp

locations or expose them to rain or snow.
