6. HANDLING AND TRANSPORTATION

For safe handling and transportation use a lift truck for movement indoors . Keep the machine in its normal position .

All handling and transportation operations should be carried out by trained staff .

7. MACHINE INSTALLATION

A. MACHINE CHECK

The machine should be checked to make sure that it has not been damaged during transportation and handling . If the
machine appears to have been damaged, contact MACC immediately. Fit all the supplied accessories onto the machine

B. FASTENING OF THE MACHINE

The machine will be able to operate in keeping with the technical parameters supplied by MACC if it is
positioned correctly and fastened securely to the bench or the factory floor so that vibrations are minimal
during operation . Levelling : Open vice jaws manually to maximum extent . Place machine level on vice bed
and level machine using the levelling screws provided .

C. ASSEMBLY OF CIRCULAR BLADE

1-Remove guard 61 exposing saw shaft and saw collars .
2-Remove bolt 97 and outside flange 57 .
3-Loosen screw on pinchip wheel bracket and slide pinchip wheel out of the way .
4-Mount the saw blade on the arbor with teeth of blade moving counter clockwise .
5-Move pinchip wheel into the saw blade , meshing the pins and teeth loosely . Rotate the blade by hand to ensure
proper mesh with pinchip wheel . The pins should not protrude through the saw blade more than 1/16” .
6-Replace outside flange 55 and bolt . Turn blade clockwise up against drive pins and securely tighten bolt .
7-Replace guard 61 .
( Points 3 and 5 should only be followed for machines with scrap-breaker ) .

D. ELECTRICAL CONNECTION TO THE MAINS

Install a differential thermomagnetic switch with characteristics suited to the mains .

Make sure that the power supply voltage corresponds to the voltage on the motor plate . Connect the cable to the power
supply line observing the colour codes of the individual wires , pay particular attention to the earth wire . Connect the
machine , make sure that the rotation of the circular blade is in the direction shown by the arrow on the guard .

E. CUTTING COOLANT

For the cooling of the circular blade , fill the tank with emulsible oil obtained from a mixture of water and WLADOIL
EMULSOL SGA/NF oil with a percentage of 5-7%
