7.2 Recommendations for use

The machine has been designed to cut machinable metal
and plastic materials of various shapes.
Only one operator is needed to operate the machine.
Figure 7-2: Safe Operator Position
- Before starting each cutting operation, ensure that the
part is firmly clamped in the vice and suitably
supported.
- The figures below show examples of suitable clamping
of different section bars, bearing in mind the cutting
capacities of the machine in order to achieve a good
efficiency and blade durability.
Knock off sharp edges with a file.
Figure 7-3: Suitable Vise Clamping Options
- Do not use blades of a different size from those stated
in the machine specifications.
- If the blade gets stuck in the cut, press the emergency
stop button (I, Fig 7-1) immediately to switch off the
machine.
Open the vice slowly, remove the part and check that
the blade or its teeth are not broken. If they are
broken, change the blade.
- Before carrying out any repairs on the machine,
consult your dealer.

7.3 Blade Speed Selection

The general rule is the harder the material being cut, the
slower the blade speed.
- 20-30 m/min
For stainless steel, tool steel, bearing bronze.
- 30-45 m/min
For alloy steel, hard cast iron, hard bronze
- 45-60 m/min
For mild steel, soft cast iron, medium hard bronze,
hard aluminium
- 60-85 m/min
For plastic, soft and medium aluminium, other light
materials.
Note:
The cutting speed depends on the material tensile
strength ( N/mm
the widest cutting section (mm).
The machine has a variable cutting speed range of 20 to
85 m/min.
Rotate knob (N, Fig 7-1) to set the blade speed.

7.4 Vise Operation

Make sure the power source is same as indicated on the
machine ID-label.
Connect the machine to power source. Turn the main
switch (A, Fig 7-1) on. The power lamp (C) will be lit.
1. Press button (D) to start the hydraulic pump.
Note: If the hydraulic pump fails to start, or if pump
starts but saw bow does not go up when selected by
switch (K), that means that pump motor is running
wrong direction. Change two of the phases.
