2.
Check
blade specification. The improper blade specification will create
additional spalling or chipping of the concrete. For best results use a
Norton GMAX series Blade. The Norton GMAX series have unique
features to improve the green concrete cut quality and the overall
efficiency of the blade while cutting green concrete. The GMAX blade
provided with the GC55 was designed exclusively for use on this product
to provide maximum performance and a precision cut appearance!
3.
Check
blade for wear. As the blade loses width the cut appearance will
get worse. Blades with segments that look like a knife blade need to be
replaced immediately as a blade in this condition will create a poor quality
cut line.
4.
Check
concrete surface for flatness.
5.
Replace
the blade with a new blade of the same specification.
6.
Replace
blade with the correct specification.
Cut Appearance Previously Fine But Now Constantly Spalling or
Chipping On One Side Of The Cut:
1.
Check
for
warped blade. A warped or out of tension blade will create a
cut that has spalling and chipping. Replace blade if necessary.
2.
Check
the tracking on saw.
3.
Check
that the machine is being pushed in a straight line.
Thin Shell Chipping of Concrete:
1.
Wait
1 to 2 hours for the concrete cure depth to increase. Shell chipping
is caused when the top layer of concrete is curing at a faster rate than the
concrete below. The concrete needs to cure to a deeper depth in order to
prevent the shell chipping.
