Assembly instructions
22. The Dolly is designed to be fitted to Metabo 9” Hand grinders that has a suitable diamond disk and a dust
shroud fitted to it. The intention is that the hand grinder can be used without the user being on their hands
knees.
23. Other Brands of hand Grinders may fit but it is not guaranteed
24. Due to the Nature of hand grinders it is almost impossible to simulate the ability to follow the floor when
using a D handle, Due to this, the dolly may be susceptible to leave groves and gouges and also miss certain
sections of the floor that are lower. This can be expected.
25. This Dolly is supplied with the following fasteners.
26.

Operating Instructions
40. Wear clothes suitable for the job and for the work place including, safety shoes, hard hat, hearing protection,
non-fogging vented safety goggles, and dust respirator suitable for dust.
41. The Dolly must only be used according to the instructions given in this manual. Any other work
methods or practices could result in injury or death
42. WARNING! POISONOUS EXHAUST GASES. Do not operate petrol powered equipment, including generators,
without adequate ventilation. Carbon monoxide is and invisible odourless gas that can harm or can kill.
43. Be sure all equipment is tested and tagged prior to use on any job.
44. Inspect entire area to be ground before grinding and remove any bolts or concrete nails (etc) that could
damage tooling or the machine and which could cause a hazardous situation.
45. 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.
46. Tilt the machine back so handle is resting along the floor.
47. Install appropriate diamond tooling or other available tooling into the machine. Only use genuine tooling.
Failure to comply could result in bodily injury.
48. Tilt machine back onto the disk.
49. Connect machine to suitable power outlet. Only use heavy duty power lead suitable for high current use
(preferably 2.5mm² cable), no longer than 20 meters.
50. If no power is available within the specified distance, have a qualified person install a suitable power outlet
closer to your work. Alternatively use 4mm² cable for up to 50 meters.
51. Connect a suitable dust extractor to the machine via a 38 or 50mm flexible hose. The machine is designed to
take the standard 50mm hose ends to make connection of dust extractors easy and hassle free.
52. Keep machine clear of drainage pits, grates, steps or major lips or such hazard. Failure to comply could result
in bodily injury and or could damage the machine or property.

Operating Instructions
54. Switch on the dust extractor.
55. Hold the handles firmly and switch the Dolly on by pulling the toggle switch on with your finger.
56. 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.
57. 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.
58. WARNING! As with any diamond tooling, 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.

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.

Warranty
The Dolly is offered with a 1 year Limited manufacturer’s Warranty against defects. This does not mean the machine
is indestructible or will not require replacement parts as there are some parts which are normal replacement items
and the wear is not a fault of manufacture.
Warranty on Metabo or other brand tools are subject to that manufacturer’s warranty terms. For warranty on the
hand tool please take the tool to your local agent.
Our goods come with guarantees that cannot be excluded under the Australian Consumer Law. You are entitled to a
replacement or refund for a major failure and compensation for any other reasonably foreseeable loss or damage.
You are also entitled to have the goods repaired or replaced if the goods fail to be of acceptable quality and the
failure does not amount to a major failure.
As these goods are not of a kind ordinarily acquired for domestic, household or personal use, Con-Treat is entitled
to limit their liability to sellers (companies or individuals who resell the machine) to the cost of replacing the
goods, having the goods repaired or obtaining equivalent goods (whichever is lowest).
Consumer Guarantees are a contract between the seller and the consumer. For this reason if goods are purchased to
be resold or to be transformed into a product that is sold, the consumer guarantees between Con-Treat and the re-
seller will not apply.
Compensation - Manufacturers are not responsible for problems with goods beyond their control. For this reason
Con-Treat will not be held liable for:
1. An act, default, omission or representation made by some other person (excluding an employee or agent of
the manufacturer).
2. Contract penalties such as promises for completion date of jobs. These are at the risk of the parties involved.
3. A cause independent of human control that occurs after the goods left the manufacturer’s control
The consumer guarantees require you to return goods to the place where they were purchased unless it is not
reasonable for you to do so. For example, it would be reasonable to expect you to return an item if you would be able
to easily take it away with you when you purchased it. However, if the item is large, heavy or bulky or needed to be
delivered, the seller should arrange for this to be returned.
For this reason for timely repairs and as little downtime for the consumer, Con-Treat may offer to have the
machine repaired by a nominated repairer close by.
