TROUBLE SHOOTING DIAMOND BLADES

*A lot of those problems can be prevented by*
1. Reading the operators manual.
2. Using the proper blade for the material being cut and the right bond.
3. The machine is in good operating order.
4. Do not force the blade. Let it do the work.
5. Make sure the blade is properly cooled.

BLADE TENSION LOSS
CAUSE - Mismatched blade collars
THE FIX - Make sure both collars are the same size. You should be using a minimum 4" diameter collar, a 6" on blades over 30" and a 8" on blades over 48"
CAUSE - Misaligned saw
THE FIX - Check wheel alignment
CAUSE - Blade bond to hard
THE FIX - Use a softer bond blade
CAUSE - Running saw at the wrong RPM
THE FIX - Make sure you shaft RPM is right for the diameter blade your using
CAUSE - Improper mounting
THE FIX - Make sure outside collar and nut are securely fastened and the blade is flush with both collars

UNDER CUTTING
CAUSE - Not using the right spec. blade for the material being cut. The blade lacks undercut protection
THE FIX - Make sure you use the right spec blade for the material, make sure blades used cut abrasives materials have the proper undercut protection as well as larger diameter blades.

BLADE ARBOR OUT OF ROUND
CAUSE - Blade not securely tight
THE FIX - Tighten collars and nut
CAUSE - Dirty or worn shaft or collars
THE FIX -  Clean / replace shaft and collars

SEGMENT / CORE CRACKS
CAUSE - Blade bond is to hard
THE FIX - Use a softer bond blade
CAUSE - Forcing the machine, jamming  or twisting the blade when it's in the cut
THE FIX - Never force the machine. Always feed the blade with a steady even pressure
CAUSE - Inadequate blade cooling
THE FIX - Check water feed supply and use adequate water when cutting
 

UNEVEN SEGMENT WEAR
CAUSE - Uneven cooling in the blade sides
THE FIX - Check waterways for obstructions
CAUSE - Saw head misaligned, shaft misaligned
THE FIX - Check head and shaft alignment
CAUSE - Bad shaft bearings
THE FIX - Replace bearings
CAUSE - Blade arbor hole out of round
THE FIX - Check/replace blade shaftSEGMENT LOSS
 

SEGMENT LOSS
CAUSE - Overheating
 THE FIX - Check waterways for obstruction, use adequate water
 CAUSE - Undercutting
 THE FIX - Use the right spec for material being cut. Don't run the blade too deep, use blades with proper undercut protection. Increase water supply to the blade when cutting.
 

BLADE WILL NOT CUT
CAUSE - Wrong bond, bond too hard
THE FIX - Change the bond, use the right spec blade, use softer bond, Call Prolink 1800 995 6782
CAUSE - Forcing the blade
THE FIX - Feed the blade with a steady even pressure
CAUSE - Too much water (concrete only)
THE FIX - Using too much water when cutting concrete will prevent the segment from properly wearing and exposing new diamonds as it's cutting
CAUSE - Not enough horse power or loose belts
THE FIX - Use higher horse power equipment, tighten shaft belts
 

BLADE CORE BURNING OR BLUING
CAUSE - Insufficient cooling
THE FIX - Use proper amount of water
CAUSE - Blade is out of tension
THE FIX - Re-tension blade
 

CORE BIT TROUBLE SHOOTING

 SEGMENT GLAZING
CAUSE - Too much feed pressure
THE FIX - Open bit by running it in abrasive material such as block or sand. Feed the bit at an even rate. Use steady pressure when going thru steel. Never force the bit and let it do the cutting
CAUSE - using to much water (concrete only)
THE FIX - You should have a steady stream of water coming out to clean out the sediment the drilling so the bit will not get stuck. (just enough)
Using to much water will prevent the segment from wearing properly and exposing new diamonds
 

BENT SEGMENTS
CAUSE - Too much feeding pressure
THE FIX - Back off on the feed rate
CAUSE - The material being drilled is to hard
THE FIX - Use a softer bond bit

 SEGMENT LOSS
 CAUSE - Steel reinforcing
 THE FIX - Ease up a little on the feed pressure when going thru the steel
 CAUSE - Not enough water cooling
 THE FIX - Use more water
 CAUSE - Equipment improperly mounted or loosely mounted
THE FIX - The drill must always be firmly mounted to the surface your cutting. Drilling with a loose mounted drill can also result in serious injury

 CORE BIT GETS STUCK
 CAUSE - Not using enough water to clean the slurry out when drilling
 THE FIX - Use more water
 CAUSE - The core can is damaged or bent
 THE FIX - Have new segments remounted on a new core can or purchase a new bit
 CAUSE - No segment side clearance, the segment width is smaller then the core barrel wall preventing proper water flow for removing the slurry when drilling
 THE FIX - Call 1-800 995-6782 and purchase a new bit. Mount new segments on the core
