Operating Instructions
40. The GALAXY has axle height adjustment to level the machine and also assists ergonomics of the machine so
as to cause less fatigue on the operator. To set axle height, place the machine on a level surface and adjust
the axle height lever until the level bubble is somewhat in the centre. After initial operation the axle can be
adjusted to fine tune the results.
41. Switch on the dust extractor or turn on the water tap so a small amount of water is spraying on the tool.
42. Hold the handles firmly and
a. For electric machines; switch the machine on by pushing the green button.
b. For Petrol Machines; Put the throttle lever in the choke position (fully towards operator) and pull start
the engine. Note; some machines have auto choke and the Idle position is adequate for starting.
Caution!! When Starting the machine in the full choke (when Cold) the machine clutch could engage
for a short period until machine it taken back to idle. Be aware of this and have a second operator
hole the handle to ensure the machine is kept controlled.
c. As soon as the engine is started, move the lever to the idle position. And when ready move the lever
to the full throttle position.
43. On electric machines, the controls on the GALAXY include an over load device. It is there to protect the
controls and motor from irreparable damage. If it trips it indicates a problem. (i.e.; undersize power lead or
poor power to your power supply). Refer earlier in this section for recommendations on power leads. Rectify
the problem or decrease load on the GALAXY by using tooling with more surface area.
44. Continuing to use the GALAXY when constant tripping occurs, VOIDS THE WARRANTY.
45. 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 or spark plug disconnected.
46. In the event of the machine pulling to one side all the time; adjust the axle height to obtain the best result.
(See section ‘Axle Height’). 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.
47. 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. There is a wide range of diamonds
available to suit every need. See Section ‘Diamond Tooling Selection Guide’.
48. See Section ‘Problem Solving’ for tips on how to grind faster on tough concrete and how other problems can
be rectified.
49. WARNING! As with any diamond tooling, breathable silica or other hazardous dusts may be generated by use
and maintenance of this machine. The dust 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
54. 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.
55. There is a level bubble provided (located behind the motor) for levelling the machine for best user experience
and coupling life. It does not change the grinding results in any way.
56. The axle lever should be set so the bubble is up to the forward line on the spirit level. This assures the
longevity of the coupling life and gives the nicest position for ease of use. (Assuming the floor is level)

Problem solving
74. 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 (15meters max) or
4mm² (40 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 weight on the handle.
The weight on the handle reduces
the load on the machine thus
reducing the current.
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.
Reverse the rotation of the
machine (switch on the
bottom of the motor box)
The tooling exposes the diamonds
when reversed. This works best
when using plugs.
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.
The diamonds are too
soft or too few.
Use weights on the handle
This reduces the weight on the
diamonds thus reducing the wear
on them.
