non-fogging vented safety goggles, and dust respirator suitable for dust.
2. WARNING! POISONOUS EXHAUST GASES. Do not operate petrol powered equipment without adequate
ventilation. Carbon monoxide is an invisible odorless gas that can harm or can kill you.
3. Be sure all equipment is tested and tagged prior to use on any job.
4. Inspect entire area to be ground before grinding and remove any bolts or concrete nails (etc) that could damage
diamond tooling or machine which could cause a hazardous situation.
5. Ensure there are no obstacles or existing structures that could present a hazard to the operator. If so, take
necessary action to eliminate the hazard.
6. Lock handle into the operating position and lock in place using the cross knobs, then tilt machine back so handle
is resting on the floor.
7. The blade is removed by inserting screwdriver provided into the bearing unit.
8. Install appropriate diamond tooling or other available tooling into the machine. Only use genuine PME 180

to your work. Alternatively use 4mm2cable for up to 60 meters.
13. Connect a suitable dust extractor to the machine via a 38mm flexible hose. The machine is designed to take the
standard FLOOREX 50mm hose ends to make connection of dust extractors easy and hassle free. A suitable length
of 50 mm hose can be added after 5 meters of 38mm hose.
14. Keep machine clear of drainage pits and grates or any such hazard. Failure to comply could result in bodily injury
and or could damage the machine or property.
15. Ensure machine is on a level surface and handle is not folded.
16. On the dust extractor.
17. Hold the handles firmly and switch the machine on by pushing the green button.

Operating instructions cont…
18. The switch is an over load switch. If it trips it indicates a problem. (Example; undersize power lead or poor power
to GPO outlet). Refer to previous section for recommendations on power leads. Rectify problem or decrease load
on grinder by using tooling with more surface area. Continuing to use the PME 180 when constant tripping occurs
VOIDS THE WARRANTY!
19. 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.
20. Adjust the wheel height to make the blade sit flat on the floor. This ensures the long life of the coupling. If the
coupling has to flex a lot it generates heat and excessive wear which is not covered by warranty.
21. 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. See section Diamond tooling’
22. See section problem solving for tips on how to grind faster on tough concrete and other ways problems can be
rectified.
23. 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.

Electrical safety
1. All electrical maintenance and repairs to be carried out by qualified persons only.
2. CAUTION - Line terminals may be alive when main switch is in the off position. Disconnect all power at source
before performing any maintenance or repairs.
3. WARNING - DO NOT operate the machine with any electrical panels open.
4. WARNING - The switch on the PME 180 is an overload switch and will trip when under excessive load The
Overload will automatically reset when safe to do so.
5. Continuing to use the PME 180 when constant tripping occurs, VOIDS THE WARRANTY!
6. Never operate machine in the rain or if heavy moisture is present.
7. The overload is there to protect you and the machine from harm. DO NOT alter or adjust the over load in any
way. If it is faulty, only replace with original part that is identical to the faulty one.
8. Never bypass over current devices in this machine.
9. Never connect or disconnect power cables with voltage present or while under load.
10. Disconnect all power connections and observe lock out / tag out procedures before attempting to carry out any
maintenance or repair on any equipment.

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 (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.
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.
