Frame and feet (1)
The frame is made of a jig-welded reinforced steel construction to ensure perfect rigidity. 4
removable legs fit into housings welded on frame sides and locked into place with wing screws.
Cutting head (2)
Spring loaded jig-welded steel console. The motor fixing points and the pivot are machined for
perfect fit. A locking system allows straight-through cutting without any other accessory.
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.
Blade shaft (4)
The inner collar is pressed onto the motor shaft, and the outer flange is tightened with a hexagonal
nut (thread opposite to blade direction!).
Conveyor cart (5)
Steel welded construction with non-slip top.
The machine patented guide system permits precise cuts to be made by virtue of four roller sheaves
set at an inclination to compensate for wear.
The nylon-plastic sheaves and sealed-bearings permit easy operation. The variable angle guide-a-
cut and the large surface area of the conveyor cart permits precise positioning of the material.
Water cooling system (6)
The coolant system comprises:
•
A powerful, submersible electric 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 the blade guard ensure adequate flow of water to both sides of
the cutting blade.
•
A water curtain, fixed to head axle restricts water spray and minimises water loss.
•
The pump switch is located on the right side of the main switch.
Electrical Motor (7)
Leroy-Somer motor. The electric motor has an overload protection. Thermal overload tripping can
occur for two reasons: tripping under light load if connection is incorrect, and tripping under heavy
load if motor has been overloaded.
The ON-OFF switch also serves as emergency stop. The pump switch is located on the right side of
the main switch. Low voltage trigger (NVR) built in the switch prevents the motor to restart for
example after a power cut.
