H. Inspect the Center and Beveling Cutters for broken teeth or cracks that might eventually cause blade breakage when
machine is stopped. Always use sharp cutters for optimal machine performance.
I. For operator safety the Blade Guard should always be closed when the Cutters are rotating.
J. When the machine is in operation, personnel not involved in the machine operation must stay at a safety distance or
wear the necessary safety equipment.
K. The CGM-1 operator should always be in close proximity to the machine when the machine is connected to a Power
Supply Unit that is in operation and the cutters are rotating for quick access to Machine Controls.
L. The Air or Hydraulic Power Supply Unit must be turned off and Hose pressure released before disconnecting hoses.
M. The proper machine forward speed must be selected for the specific thickness of pipe to be cut.
N. Clean the cutting area with water or approved low-pressure compressed air and avoid cleaning the cutting area
manually using wrong tools that may catch in the blades.
O. Check the machine for worn parts and replace them before returning the machine to its storage case.
P. Schedule and perform regularly scheduled maintenance on CGM-1 to insure operator safety.
IN ADDITION TO THE ABOVE PROCEDURES, ALL SAFETY INSTRUCTIONS
CONCERNING HYDRAULIC AND/OR PNEUMATIC SYSTEMS SHOULD
ALSO BE ENFORCED. ALL THE OPERATIONS MUST BE DONE UNDER
THE BEST SAFETY CONDITIONS.
5. OPERATING INSTRUCTION
5.1 CONNECTIONS AND POWER-SOURCES.
PNEUMATIC MACHINE - Join the Machine to an Air Compressor having the properties mentioned in Section 2. Use
of an Air Compressor smaller than that specified in Section 2 will drastically hinder performance and may damage the
CGM.
A. If an Air Hose longer than 15 meters (50 foot) is required, the hose diameter should be increased accordingly to insure
the CGM receives an adequate amount of pressure and volume of air.
B. An Air Regulator, Filter and Lubricator Group must always be installed in the Air Supply Line between CGM and the
air compressor to control air pressure to CGM.
C. The Regulator of the Air Filter/Lubrication Device should be set at 90psi (6 Bar).
D. Connect the Cutter Lubricator System to the coolant container. Use a Synthetic Coolant Oil type BIO/42 EP or
similar.
