1. wander or bend in the cut giving the illusion of an out of alignment condition If you experience any lack of cutting efficiency or effectiveness sharpen your diamond blade by making several cuts into a very abrasive material such as simple cinder block or soft sandstone FINAL INSPECTION The blade guard should be inspected daily for any signs of cracks or breaks Any time a blade fails the inside of the blade guard should be inspected immediately for any stress cracks before continuing If damage is found replace the blade guard immediately A blade guard should be replaced after three blade failures even if there are no visible signs of cracks or breaks Always check the blade after each use inspecting for stress cracks and broken segments Either of these conditions war rants replacement of the blade prior to next use of the saw BLADE STORAGE Do not store the blade mounted on the cut off saw Store blades on a flat surface in a dry place Failure to follow these directions for storage my cause the blade to shatter or crack in use causing serious or fatal injury 13 15 AAA Fire Tiger Tooth Safety Instruction Manual OWNERS MANUAL amp OPERATING INSTRUCTIONS DOCUMENT NO 167956 REVISION 100 09 09 MO MK Diamond Products Inc MK Diamond Products Inc 1315 Storm Parkway Torrance CA 90501 Toll Free 800 845 3729 Phone 310 539 2221 Fax 310 539 5158 www mkdiamond com2. Avoid inhaling exhaust fumes and never run the engine in a closed building or confined area 9 WORKING TECHNIQUES USING THE SAW REACTIVE FORCES Pull away To achieve a clean and efficient safe cut pull the blade across the material or move it back and forth in the cutting direction Do not force the blade into the mate rial Thick walled work pieces should be cut with a swinging movement back and forth Allow the wheel to cool by releasing pressure and freewheeling the blade by pulling the blade out of the cut every 60 90 seconds and running it for 10 15 seconds Insert the blade into the material only as deep as necessary to make the cut To reduce the amount of dust created do not cut all the way through the material leave a thin piece uncut For most materials this piece can be easily broken afterwards Keep the blade 90 to the cut to prevent it from being cocked jammed or wedged in the material Always stop the cut off saw and be sure that the blade has stopped spinning before setting the cut off saw down To reduce the risk of serious or fatal injury do not change the direction of the cut during the cut as this may produce a high torsion load on the blade and may cause itto break shatter or develop stress cracks It is essential to determine the exact direction of the cut before applying the blade to the work material Blades are constructed for radial pressure only Lateral pressure must be avoide
3. under tension What is the proper position of the operator in relationship to the cut A CAUTION Always cut from the outside perimeter of the area being cut Correct Method WORKING TECHNIQUES BLADE INSPECTION Only use the approved blade for the type of material to be Blade Diameter Maximum Safe Speed RPM cut Before mounting the cutting blade make sure that the CT maximum operating speed of the blade is above or equal to 6 300 the spindle speed of the cut off saw A blade used at a higher speed than that approved may shatter or break and poses a threat of serious or fatal injury to the operator and other nearby persons Always inspect the blade prior to mounting or use and replace immediately if the blade shows any signs of cracks or is warped Cracked or warped blades may shat ter or break and cause serious or fatal personal injury Out of round or unbalanced blades increase vibration and can also develop excessive heat build up during cut ting Refer to page 12 for details The Fire Tiger Tooth blade is a bi directional blade and can be used rotating in either direction Most other blades are designed to be operated in only one direction and must always be mounted so that the arrow on the blade points in the direction of rotation of the spindle Do not remount a used blade without first inspecting for cracks flatness core fatigue segment damage or loss signs of overheating discoloration and or

8. d Hold the cut off saw steady at all times Re entering an existing cut must be done slowly and carefully To reduce the risk of injury from shattered blades Do not exceed the maximum operating speed of the blade Do not use the blade if it has been dropped Do not cut any material for which the blade was not made to cut Do not grind on the side of the blade Do not twist thrust knock or drop the cut off saw An understanding of causes of reactive forces may help to avoid loss of control Reactive forces are exerted in a direction opposite to the direction in which the blade is turning at the point of contact or pinch Kickback Reactive forces may occur at any time during cutting If the blade is slowed or stopped by frictional contact with any solid object or by a pinch reactive forces may occur instantly and with great force These reactive forces may result in the operator losing control of the saw which may in turn result in serious or fatal injury Pull away climbing pinching and rotational kickback forces The most common reactive forces are pull away and climbing If the contact is at the bottom of the blade a cut off saw will try to pull away from the operator pull away If the contact is at the front of the blade the blade may attempt to climb the object being cut climbing Pinching occurs when the material being cut closes on the blade If the blade is severely pinched at the front especially in t

13. ium Always check the blade after unintentionally striking any object frequently check the blade during use after stopping Look for cracks and make sure that it is undam aged and in good condition and that no pieces have broken off If the blade shows signs of excessive heat then remove the blade and inspect the steel core for crack Blade should be removed from cut after one minute and allowed to cool free wheel ing for 10 to 20 seconds The segment has lost all the diamond crystal which if used will result in build up which will result in cracks If you continue to use a blade with blunt segments this will result in excessive heat build up The blade core will also over heat and lose its mechanical strength This can lead to considerable stress as clearly indicated by stress cracks and or a wobbling movement of the blade Such blade may break apart or throw off a segment or segments during use causing serious or fatal injury Replace immediately 12 INSPECTION BLADE SHARPENING Like most cutting instruments a diamond blade cuts best when it is sharp When material being cut is matched with the proper diamond blade it should yield swift and accurate cuts and maintain an optimum operational life No two materials cut alike Occasions may arise where a percentage of the diamonds on the blade edge and periphery smooth glaze over and the cutting efficiency is reduced Additionally this condition may cause the blade to
