6. OPERATION
6.1 OPERATING INSTRUCTIONS
RECOMMENDED USE
The cutter-crusher is designed for use in demolishing work to crush concrete and
cut steel beams in buildings. Your local dealer will gladly give you more
information.
OPERATING CONDITIONS
Principles of installation
Almost all carriers meeting mechanical and hydraulic requirements can be used to
operate attachments. See “Product specifications” on page 78. The product is
installed on the carrier much in the same manner as installing a bucket or other
attachments. A flange mounted attachment requires also a separate mounting
bracket.
The attachment is connected to a carrier's hydraulic circuit with an installation kit.
If the carrier is already fitted with an installation kit, the installation requires only
suitable hoses and fittings. For crusher installation, secondary relief valves in
bucket cylinder circuit and in carrier auxiliary circuit are needed. If the carrier does
not have suitable kit to run attachments, one must be built. This may require more
complex installation including new piping and additional valves such as flow
control valve or pressure relief valve.
Suitable kits can be ordered from the manufacturer or local dealers, from carrier
manufacturers and their dealers or from third party suppliers.
Hydraulic oil
In general the hydraulic oil originally intended for the carrier can be used with this
product. See “Requirements for hydraulic oil” on page 45.
Operating temperature
The operating temperature is -20 °C (-4 °F) to 80 °C (176 °F). If you must work in
a temperature lower than -20 °C (-4 °F), the equipment has to be preheated before
any operations can begin. Start the operation with low hydraulic flow.
Note: The temperature of the hydraulic oil must be monitored. Ensure that oil grade
and monitored oil temperature together guarantee correct oil viscosity. See “Oil
specifications” on page 46.
