Safety Instructions
1. Read and understand the instructions on the machine and in this manual.
2. Equipment should only be operated by trained personnel who are in good
physical condition and mental health (not fatigued). The operator and
maintenance personnel must physically be able to handle the bulk, weight
and power of this machine.
3. The RUBICON 480 must only be used in accordance with the instructions
given in this manual. Any other work methods or practices are not approved
and could result in serious injury or death.
4. The handle of the RUBICON 480 can be locked into different positions:
OPERATE, TOOLING and LIFT/STORAGE. Diagrams of these positions are
available in the Handle Positions section of this manual. The appropriate
circumstances to use each position is described throughout the manual.
5. This machine is intended for operation only by a single person: ‘one
machine, one operator’. Always be mindful of people working in the same
area and maintain a safe operating distance to avoid injury.
6. This equipment is intended for commercial use.
7. For the safety of the operator and others working in the area, ensure guards
and shrouds are always in place and never run the machine without them.

23. WARNING: POISONOUS EXHAUST GASES. Do not operate petrol powered
equipment, including generators, without adequate ventilation. Carbon
monoxide is an invisible, odourless gas that can harm or kill.
24. Do not operate the RUBICON 480 with any of the doors or panels removed,
open or not properly secured.
25. The RUBICON 480 can produce sound levels in excess of 85db. The operator
must wear approved safety hearing protection.

blade, head, or other moving parts on the machine.
27. 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, as silica may be present in the air without
a visible dust cloud. Appropriate respiratory protection must be worn when
operating and maintaining this equipment.

36. The machine takes a set of three diamond tools. Be sure the tools installed
are of even height.
37. Install the tooling with the machine in the TOOLING position. See the
Tooling Position & Magnetic Plugs section for illustrations on how to
correctly install and remove the tooling. Only use genuine retailer’s genuine
diamond tooling with the machine. Failure to comply could result in bodily
injury or damage to the machine or property.

49. The controls on the RUBICON 480 include an overload device to protect the
motor from irreparable damage. A problem is indicated if the overload is
tripped (ie. undersized power lead or poor power supply). Appropriate power
leads are recommended at Points 40 and 41. Address the problem or decrease
the load on the machine by using tooling with more surface area or use the
weights that have been supplied for this purpose (place them on the brackets
at the base of the machine’s handles).
50. Continuing to use the RUBICON 480 when constant tripping occurs VOIDS

51. Do not attempt to make any adjustments while the machine is in operation.
Any adjustments must only be performed when the machine has fully
stopped, and the power has been disconnected.

minutes of grinding, to see if the diamonds are wearing out too fast due
to soft concrete / abrasive concrete. There is a wide range of diamonds
available to suit every need.
54. Continue to check for wear on magnetic plugs every three hours of use.

59. Name of model:
60. Transportation and storage of the motor:
1. Transportation : During transportation, the motor must be kept in an
upright position and placed on a level surface, without being tipped on its
back or side. If it is being moved with a crane, it should be lifted and lowered
slowly without jerky movements. Always avoid damp or dirt penetrating the
motor: ensure it is kept away from rain.
2. Storage : The motor should be stored in a dry and well-ventilated indoor
area and kept away from being stored together with corrosive gases.
61. Preliminary checks before operation:
1. Check the insulation resistance : Before the motor is put into operation,
the winding insulation resistance must be measured. The measurement of
insulation resistance is carried out by means of a Megohmmeter with 500V
applied between the windings and the ground of the motor. The rate of the
resistance must be greater than 20 Megohm, otherwise the winding should
