8.3 OPERATION
CHECKS TO CARRY OUT BEFORE EACH CUT
A. Tension the band by rotating the handwheel 56 till the end of the traverse. On the display does not blink the signaling
“Broken Blade”. Remember at the end of the operation to loosen the hand wheel to avoid the slackening of the band.
B. Check that the hand indicates the required cutting angle (vice scale).
C. Make sure that the bow and the vice are locked by means of the lever 63 (DRAW. 8 ENCL. 3).
D. Adjustment of bow-stroke: the two cutting stopsare made up of two limit switches located on the bow support arm 59.
To adjust the upper stop position the bush 83 on the upper limit switch. For the lower stop adjust the bush 84.
E. Make sure that the piece to be cut is properly secured in the vice;
F. Make sure that the cooling liquid is circulating in the machine. Use the taplocated on the guide shoe to regulate the
flow of liquid.
G. When starting the motor, make sure that the band rotates in the direction of the arrow shown in Draw. 3-4-5 Encl.3.
H. To obtain maximum cutting accuracy, the unit must be located the nearest possible to the workpiece. Clamp
the work piece with the vice, release the
m
obile blade guide plate 32 with screw and move it near the vice jaw so
that it doesn’t touch it during the cutting operation, then secure it again. When carrying out this operation, make
sure that the blade guide guard does not come out of the bow guard leaving a part of the blade exposed.
CUTTING OPERATION
A. Before cutting, check that the inclination is the one required. In order to correct or change the inclination, place the
bench lever 63 in position B (DRAW. 4 ENCL. 2) and after correction, move it back to position A.
B. For other information regarding the cutting operation and machine programming, follow the supplied MACC4
instructions carefully.
C. To replace the band, carry out the same operations used to assemble the band (chapter 7c).
D. For the choice of blade see table DRAW 1 ENCL.1.
