PROBLEM SOLVING
Diamond Grinding has many variables. When you understand some of these, you can solve a lot of
problems without a lot of bother and expense.
PROBLEM CAUSE
REMEDY
WHAT IT IS DOING?
Machine will not
start / run.
No power is present
at cable end.
Check the power is present
with another tool.
Using another tool confirms power is
present
Machine is trying to
start on glue or
other sticky
substance.
Clear a patch with a scraper
and grind into the glue a little
at a time.
This means it only tackles a small amount
of glue at a time and keeps the glue residue
coated with dust, preventing glue build-up
on the diamonds.
Power lead is too
small in capacity or
too long.
Upgrade the power lead to
2.5mm² (15meters) max or
4mm² (30 meters max).
The long / small capacity cable is too
restrictive and can’t allow enough power
through for the machine to start / run
properly.
Use weights on the brackets
on the handle.
The weight reduces the load on the
machine thus reducing the current draw.
Machine is not
grinding at all.
No blades /
accessories in unit.
Fit blades.
Note; check wear
on machine.
Very hard concrete
or glazed topping on
concrete.
Turn dust extractor down /
restrict flow. Only just control
the dust from escaping.
The extra dust accumulating on the floor
acts as an abrasive between the segments
and the floor thus exposing the diamonds
better.
Place river sand or equivalent
on the floor.
The sand is an abrasive as described
above.
Use softer grade of diamond
tooling.
The softer grade will expose the diamonds
better.
Use coarser diamond tooling.
The coarser diamond tooling can get
through the hard topping without wearing
out the diamonds too fast.
Place weights on the machine The extra weight exposes the diamonds
better, therefore grind faster
The diamonds
are wearing out
too fast.
The concrete is:
*Soft
*Abrasive
*Rain Damaged
*A rough finish
(Scarified /brushed).
Use a powerful dust extractor
to remove as much dust as
possible.
The dust, as described acts as an abrasive
between the segments exposing the
diamonds prematurely, wasting them.
Use harder diamond matrix.
The harder segments don’t expose as
easily.
Use tooling with more
segments or area² of
segment.
The tooling with more segments or area²
doesn’t have the same weight on them,
reducing wear.
The diamonds are
too soft or too few.
Use weights on the brackets
on the handle.
The weight on the handle reduces the
weight on the diamonds thus reducing the
wear on them.
NOTE: THIS IS A GUIDE ONLY
* Wheels for hard concrete should not be used on soft concrete, and will wear out quickly.
* Wheels for soft concrete will grind very slowly on hard concrete, get hot and glaze.
