6. HANDLING AND TRANSPORTATION
For safe handling and transportation use a lift truck for movement indoors (DRAW. 3 ENCL. 2). 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 the supplied accessory onto the machine
such as the fixed guard bar 73.
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 . Consult drawing 4 SPECIAL 380 A Installation plan Encl. 2
C. BAND ASSEMBLY
Remove the bow guard 45 by unscrewing the screws 182 and the washers 101. Fit the band by inserting it first between
the bearings of the blade guide heads and then on the two pulleys, tighten the blade slightly by means of the hand
wheel 56 and replace the bow guard. Check that the band is fitted with the correct direction of teeth, as shown in
drawing 5-6-7 enclosed document 3. Make sure that the band type (dimensions 3010x27x0.9) and its teeth pitch are
suited to the material to be cut.
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. ASSEMBLY OF THE LOAD CYLINDER
Put manually the mobile vice group at a distance of about 150 mm from the fixed vice as indicated in the drawing 12
enclosure 5. Fix the cylinder 124 at the load support 125, with the four (4) screws which are on the support, but without
fixing them. Start the motor with button on the control panel and lift the bow with button .
Open both the mobile and fixed vice (buttons and ).
