Safety and Usage FAQ

DIAMOND BLADE SAFETY

  • Read and understand warnings and instructions before operating any tools with these products
  • Operators AND bystanders must always wear ANSI Z78.1 eye protection, hearing protection and protective clothing.
  • Operator and bystanders must always use OSHA/ANIS approved respiratory protection suitable for the specific application.
  • Make sure the wheel is not touching anything when the tool is started.
  • Always let the wheel come to a complete stop before setting tool down.
  • Do not operate in a combustible environment; sparks can be generated which could cause a fire or explosion.
  • Do not touch or try to stop a moving wheel with your hand.
  • Do not apply side pressure to the wheel, such as side grinding, or twisting or wedging the wheel in a cut.
  • Blades are designed for maximum operating speeds. Do not exceed recommended maximum speed.
  • Do not touch a cutting wheel immediately after use, it may be hot.

Q: WHAT CAUSES CORE OR SEGMENT CRACKS?

A: THE DIAMOND BLADE IS TOO HARD FOR MATERIAL THE CONCRETE SAW IS IN NEED OF REPORARIOR THE DIAMOND BLADE IS MOUNTED IMPROPERLY.  ALSO, THE DIAMOND BLADE COULD BE OVERHEATING. CRACKS CAN OCCUR DURING CONCRETE CUTTING WHEN TWISTING WHILE CUTTING OR ATTEMPTING TO CUT CURVES.

THE BEST SOLUTION IS TO SPECIFY FOR THE DIAMOND BLADE A SOFTER BOND FOR THE MATERIAL.  ALWAYS, CHECK ALL BEARINGS, BELTS, SHAFT AND FLANGES ON CONCRETE SAW.  CHECK THE DIRECTION THAT THE DIAMOND BLADE IS TRAVELING.  FOLLOW GUIDELINES FOR PROPER BALDE OPERATION AND COOLING PROCEDURES.

POTENTIAL PROBLEMS FOR DIAMOND BLADES INCLUDE SEGMENT LOSS AND POSSIBLE CORE DESTRUCTION OF THE BLADE.  THIS IS SAN EXTREMELY DANGEROUS SITUATION WHEN CONCRETE CUTTING. DO NOT
CONTINUE TO USE THE DIAMOND BLADE.

ALWAYS LET THE DIAMOND BLADE DO THE CONCRETE CUTTING. THE BLADE IS DESIGNED TO DO THE JOB AND LITTLE FORCE IS NECESSARY.
THE CONCRETE CUTTING EQUIPMENT WILL GUIDE THE BLADE AND PROVIDE THE ENERGY TO CUT THE CONCRETE.

 

Q: WHAT ARE THE CAUSES OF DIAMOND BLADE UNDER CUTTING?

A: DIAMOND BLADE UNDERCUTTING IS WHEN THE STEEL CORE WEARS FASTER THAN THE SEGMENTS BY ABRASIVE MATERIAL BEING CUT BY
THE CONCRETE  SAW. IF NOT CORRECTED THE SEGMENTS SIDES WILL WEAR AND BREAK AWAY FROM THE CORE OF THE DIAMOND BLADE.

SPECIFIC SEGMENT DESIGN LIKE UNDERCUT PROTECTION OR SLANTED
SEGMENTS INCREASE WATER FLOW AND PROTECT THE SEGMENTS FROM
WEARING AS FAST. ALSO A DESIGN CALLED “VERTICAL SEGMENTS” CAN BE INSTALLED ON THE DIAMOND BLADE TO HELP IN THE UNDERCUTTING OCCURING ON THE BLADE.

 

Q: WHAT CAUSES SLOW DIAMOND BLADE CUTTING SPEED?

A: SLOW CUTTING USUALLY OCCURS WHEN A DIAMOND BLADE IS USED TO CUT A MATERIAL THAT IS TOO HARD FOR EHT SEGMENT. THE HARD MATERIAL WEARS THE EXPOSED DIAMONDS, BUT NOT THE METAL PORTION OF THE DIAMOND SAW BLADE.  THE SEGMENT WEARS TOO SLOWLY AND NO NEW DIAMONDS ARE EXPOSED ON THE BLADE AND THE SLOW CUTTING OF THE CONCRETE BEGINS.

THE BEST SOLUTION IS TO RUN THE DIAMOND BLADE IN A SOFT ABRASIVE MATERIAL LIKE A MASONRY BLOCK UNTIL THE DIAMNDS ARE
EXPOSED.  THIS WILL ALLOW FOR BETTER CONCRETE CUTTING WITH THE DIAMOND SAW BLADE.

IF THIS PROBLEM WITH THE DIAMOND BLADE CONTINUES, HEAT BUILDS UP ON THE BLADE AND BEGINS TO BOUNCE LEADING TO SEGMENT LOSS, CORE CRACKS AND UNSAFE CONDITIONS.

AT THAT POINT IT IS BEST TO SPEAK WITH A DIAMOND BLADE PROFESSIONAL TO FIND A MORE SUITABLE BLADE FOR CUTTING CONCRETE AGGREGATE IN YOUR TERRITORY.

 

Q: WHAT ARE THE CAUSES OF A WARPED OR WOBBLING DIAMOND BLADE?

A: IF A DIAMOND BLADE IS OUT OF TENSION, THE STEEL CORE IS NOT STRAIGHT. OFTEN, THE WRONG SIZE COLLARS ARE MOUNTED INCORRECTLY ON THE BLADE ALLOWING THE DIAMOND BLADE TO OVERHEAT WHEN CUTTING CONCRETE CREATING BLUISH BLACK MARKS ON THE BLADE.  ALSO, THE DIAMOND BLADE COULD BE RUNNING AT THE
WRONG RPM.

THE BEST SOLUTION IS TO RETURN THE DIAMOND BLADE TO THE FACTORY FOR REPAIR.  BE SURE TO USE THE CORRECT SIZED BLADE COLLARS TOO.  CHECK THE DIAMOND BLADE FLANGES AND MAKE SURE THEY ARE SMOOTH AND TIGHT FITTING.  ALWAYS FOLLOW THE GUIDELINES FOR PROPER BLADE OPERATION AND COOLING PROCEDURES.
IT IS ALSO RECOMMENDED TO THE CHECK THE  RPM RATING FOR THE DIAMOND BLADE AND THE CONCRETE SAW.

POTENTIAL PROBLEMS INCLUDE HEAT BUILD UP AND TH DIAMOND BLADE BEGINS TO BOUNCE LEADING TO SEGMENT LOSS, CORE CRACKS AND A VERY UNSAFE CONDTION TO OPERATE A CONCRET SAW.  ALSO,
THE DIAMOND BLADE WILL PRODUCT VERY POOR QUALITY CUTS.

 

Q: WHAT WILL SHORTEN THE LIFE OF YOUR DIAMOND BLADE?

A: SHORT BLADE LIFE OF A DIAMOND BLADE USUALLY OCCURS WHEN A BLADE IS USED TO CUT A MATERIAL THAT IS TOO SOFT AND ABRASIVE FOR THE SEGMENT.  THE ABRASIVE MATERIAL WEARS THE METAL OF THE SEGMENT TOO FAST WHEN CUTTING CONCRETE AND THE OPERATOR SEE’S SHORT LIFE OF THE DIAMOND BLADE.

THE BEST SOLUTION FOR THIS PROBLEM IS TO SPECIFY THE CORRECT DIAMOND BLADE AND CHOOSE A MORE WEAR RESISTANT BOND FOR THE DIAMOND BLADE.  ALSO, IT IS IMPORTANT TO CHECK THE WATER FLOW OF THE BLADE AND MAEK SURE THE DIAMOND BLADE IS RATED FOR THE QUIPMETN USED.  CHECK THE CONCRETE SAW AND MAKE SURE THE SAW IN GOOD CONDTION.

POTENTIAL PROBLEMS WILL CONTINUE IF THE CORRECT BLADE IS NOT SPECIFIED.  THE CONCRETE CUTTER WILL NOT GET THE FULL LIFE AND EFFICIENCY OF THE DIAMOND TOOL WITH OUT THE RIGHT BLADE MATCHED TO THE CORRECT AGGREGATE.
