2.1 Short description
The CM 351 Masonry saw is designed for durability and high performance for onsite wet and dry cutting operations of a wide range of
masonry, refractory and natural stone products. It can be used on construction or industrial site. Combined with NORTON diamond
blades, it offers high performance and quality cuts of materials used in construction. The machine and its component parts are
assembled to high standards assuring long life and minimum maintenance.
2.2 Purpose of use
The CM 351 is designed for wet and dry cutting of a large range of building and refractory materials, or tiles. It is not designed for
cutting wood or metals.
2.3 Layout
Frame and feet (1)
The frame is made of a jig-welded reinforced steel construction to ensure perfect rigidity. The machine is mounted on four removable
legs 4 locked with screws and equipped of wheels for transportation.
Cutting head (2)
The pivot is jig-machined with precision. A spring system brings the blade automatically in the up position. The cutting head can be tilted
to
45° for bevels cuts. Straight-through cutting can be made by means of a locking device.
Blade guard (3)
Jig-welded steel construction with 350mm-diameter blade capacity, which offers maximum operator protection and increased visibility of
the work piece.
Incorporated in the blade guard is an outer metal cover, which can be easily removed to allow easy access to shaft for inspection and
blade replacement when motor is switched off, while fully protecting the blade when in operation. The rotation of the disc is indicated by
an arrow on the sidewall of the blade guard.
Electric motor and switch (4)
Electric motor 2.2kW 230V or 2.0kW 115V with an overload protection. Low voltage trigger (NVR) built in the switch prevents the motor
to restart for example after a power cut. Thermal overload tripping can occur for two reasons:
•
tripping under light load if connection is incorrect
•
tripping under heavy load if motor has been overloaded.
The ON-OFF switch also serves as emergency stop.
