2.3 Layout
Frame (1)
The frame is made of a jig-welded reinforced steel construction to ensure perfect rigidity. It supports
the motor, the cutting table and the switch.
Cutting table (2)
Stainless steel top for an excellent resistance to corrosion with engraved measurements for precise
guide-a-cut alignment.
Electrical Motor and switch (3)
1kW motor. The ON-OFF switch also serves as emergency stop.
Blade guard (4)
Jig-welded steel construction with 250mm-diameter blade capacity, which offers maximum operator
protection and increased visibility of the work piece. The guard is assembled on the frame.
Guide-a-cut (5)
The guide-a-cut can be adjusted to the desired cutting width. It is locked using two screws.
Water tank (6)
The blade is cooled by turning inside the water tank (7) located under the working table. The water
also minimises the dust generation and improves quality of cut. It can be taken out of the machine
by unscrewing the two nuts (7). An opening (8) in the frame allows the tank to be refilled easily.
Bevel cut
You can make bevel cuts with the machine by loosening the two screws (9) and pivoting the table.
