Operating instructions
19. This machine is designed to operate with the wheels in contact with the
floor at all times. Do not operate with wheels off the floor.
20. Do not attempt to make any adjustments while the machine is in
operation. Any adjustments must only be performed when machine is
stopped and power disconnected.
21. In the event of the machine pulling to one side all the time; adjust the
axle height to obtain the best result. (See Axle Height adjustment).
22. After a few minutes of grinding check the wear of the diamond tooling.
This will pay handsomely if the diamonds are wearing out fast due to
soft concrete / abrasive concrete. FLOOREX has a wide range of
diamonds to suit every need. See page 12 and 13 for a guide.
23. See the chart on page 11 for tips on how to grind faster on tough
concrete and other ways problems can be rectified.
24. WARNING! Breathable silica may be generated by use and maintenance
of this machine. Silica can cause severe and permanent lung damage,
cancer, and or other serious diseases. Do not breathe the dust. Do not
rely on your sight or smell to determine if dust is in the air. Silica may be
in the air without a visible dust cloud. If air monitoring for silica is not
provided by your employer at your work site, you must wear appropriate
respiratory protection when operating or maintaining this equipment.
Consult your employer for proper respiratory protection.

Axle height adjustment
1. This machine is designed to operate with the wheels in contact with the
floor at all times. Do not operate with wheels off the floor.
2. The axle lever should be set so the bubble is up to the forward line on the
spirit level provided next to the motor. This assures the longevity of the
coupling life and gives the nicest position for ease of use. (Assuming the
floor is level)
Damage to the METEOR 250 MKII from neglecting this step is easily diagnosed
and could VOID THE WARRANTY!

Problem solving
Diamond Grinding has many variables. When you understand some of these, you
can solve many problems without a lot of bother and expense.
PROBLEM
CAUSE
REMEDY
WHAT IS IT 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 (20 meters) 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 blade / accessories in
unit.
Fit blade. 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.
The diamonds
are wearing out
too fast.
The concrete is:
*Soft
*Abrasive
*Rain Damaged
*A rough finish
(Scarified).
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.
