ensure that the rail (4) is parallel to the table (8). The rail assembly can also be tilted to 45º to make
bevel cuts. The rail guides the cutting head (6) over the table.
Blade guard (5)
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 hinged open. This
allows easy access to shaft for inspection and blade replacement when motor is switched off, while
fully protecting the blade when in operation. An arrow on the blade guard indicates the direction of
the blade rotation.
Cutting head (6)
Jig-welded steel console, the cutting head supports the electric motor and the blade guard. The
movement of the cutting head on the rail involves ball bearing wheels. The cutting head can be
secured on the rail using a knob screw (12). The balancing of the cutting head is achieved using a
heavy-duty spring. A depth-locking device fixed over the cutting head enables the operator to set
the cutting head to desired or to maximum cutting depth.
Down feed and cutting depth adjustment
The spring-loaded cutting head, activated by hand with any of the 2 grips (7) over the blade guard
ensures smooth lowering of the cutting head for shock-free penetration of the work piece and
improved control of the cutting pressure. The depth can also be maintained be securing the head in
at the desired cutting depth, and using any of the 3 grips (7) on the cutting head to slide the cutting
head.
Cutting table (8)
Large, heavy-duty table fitted with water flow-control vents. The table is equipped with backstops
and a guide-a-cut device (10). A side extension (9), which can be assembled on either side of the
machine, allows the cut of wide materials. The table can easily be opened to clean the water tray.
Water cooling system
The coolant system comprises:
•
A powerful, submersible electrical water pump.
•
Plastic suction pipe delivering the water from the water pan to the cutting head.
•
A large capacity water pan supplied with drain plug.
•
A water-tap, fitted to the blade guard, permitting controlled water flow.
•
Two water nozzles located on both side of the blade guard ensure adequate flow of water to
both sides of the cutting blade.
Electrical Motor (11) and switch
Electrical motor with 2,2kW. Low voltage trigger (NVR) built in the switch prevents the motor to
restart for example after a power cut.
The electric motor has an overload protection. Thermal overload tripping can occur for two reasons:
a. tripping under light load
If connection is incorrect
b. tripping under heavy load
If motor has been overloaded
