ADDITIONAL SAFETY RULES FOR

ABRASIVE CUT-OFF SAWS

1. WARNING: Do not operate your abrasive cut-off

saw until it is completely assembled and installed

according to the instructions.

2. IF YOU ARE NOT thoroughly familiar with the oper-

ation of abrasive cut-off saws, obtain advice from your

supervisor, instructor or other qualified person.

3. WEAR safety goggles, face shield, respirator, body

apron, headcovering, safety shoes, long tight-fitting

sleeves and gloves.

4. USE ONLY recommended reinforced abrasive wheels

with blotters.

5. TIGHTEN arbor screw and all clamps before operat-

ing.

6. MAKE SURE spindle lock is disengaged before

operating.

7. ALWAYS keep guards in place and working properly.

8. KEEP hands clear of cut-off wheel.

9. SECURE workpiece properly. Work should be

straight and firmly clamped to avoid possible movement

and pinching as the cut nears completion.

10. NEVER cut anything freehand.

11. NEVER reach behind or beneath the cut-off wheel.

12. MAKE SURE the wheel has come to a complete

stop before removing or securing workpiece or changing

workpiece angle.

13. MAKE SURE the inside surfaces of the wheel

flanges as well as the sides of the wheel are free from

any foreign matter.

14. WHEN MOUNTING the wheel, care should be taken

to tighten the arbor screw only enough to hold the wheel

firmly and to prevent wheel slippage. Excessive tighten-

ing may result in damaging the wheel and springing the

wheel flanges.

15. USE ONLY abrasive wheels rated at 3900 RPM or

higher.

16. ALWAYS check the wheel for cracks or other dam-

age before operation. Replace cracked or damaged

wheel immediately.

17. USE ONLY wheel flanges specified for your machine.

18. MAKE SURE abrasive wheel is not contacting

workpiece before switch is turned on.

19. ALLOW the motor to come up to full speed before

starting cut.

20. AFTER TURNING MACHINE ON, lower wheel lightly

until it comes into contact with the workpiece and then

draw wheel firmly through the cut. DO NOT allow the

wheel to chatter and jump as this may cause the wheel

to wear out of round, resulting in poor cutting and pos-

sible broken wheels.

21. ANY material can be cut more satisfactorily when

placed in position for the wheel to cut with the least arc

of contact.

22. THE NUMBER of cuts per wheel, as well as the

quality of cut, may vary considerably with the cutting

time. Fast cuts cause the wheel to wear more rapidly

but also help to reduce discoloration and burr. This is

especially noticeable when cutting light gage tubing.

When coming through the bottom wall, with the longer

arc of contact, do not slow-up but give a vigorous pull.

This keeps the metal from overheating and dragging off

in a heavy burr.

23. USE the wheel guard at all times.

24. NEVER operate the machine in an area with flam-

mable liquids or gases.

25. TO AVOID electric shock, do not use under damp

conditions or expose to rain.

26. THIS tool is designed for ferrous metals only. DO

NOT attempt to cut wood, masonry, aluminum or magne-

sium with this tool.

27. AFTER installing a new wheel, never start the tool

with a person in line with the wheel. ALWAYS run the

tool for approximately one minute before cutting. If the

wheel has an undetected crack or flaw, it could burst in

less than one minute.

28. SHUT OFF power before servicing or adjusting tool.

29. SHOULD any part of your machine 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.
