Problem solving
73. 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.
NOTE: THIS IS A GUIDE ONLY
PROBLEM CAUSE REMEDY EXPLAINATION
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 sticking and
building up on the diamonds.
Power lead is too small
in capacity or too long.
Upgrade the power lead to
2.5mm² (20meters max) or
4mm² (50 meters max).
The long / small capacity cable is
too restrictive and can’t allow
enough power through for the
machine to start / run properly.
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 cement
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 hard toppings without
wearing out the diamonds too
fast.
The diamonds are
wearing out too fast.
The concrete is:
*Soft
*Abrasive
*Rain Damaged
*A rough finish
(Scarified or shot
blasted).
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.
