11.3 - BAND RUNNING-IN
For granting a better machine efficiency and a longer blade life it is really necessary a good running-
in of the machine
.
For the first works of each band we recommend to reduce the penetration speed of the blade in the
workpiece until half of the normal value - about 40/50 cm² / min.- and keep the blade rotation speed
constant. Only after cutting 250/350 cm² of the material it is possible to increase the penetration speed till
reaching the normal value.
The working conditions can be also valued by considering the chips produced during the cutting; you can
find 3 kinds of chips:
THIN OR POWDERED CHIPS indicate poor advancing pressure and / or low speed, too little teeth.
BIG CHIPS - MAYBE BLUE / BROWN indicate overload on the blade, poor lubricating.
SPIRAL AND RIGHT ENVELOPPED CHIPS indicate the ideal cutting conditions.
For a right use see the paragraph CHOICE OF THE BAND.

11.4 - MACHINE RUNNING-IN
The recurrent maintenance that this machine needs is necessary to guarantee the continuous right working
in the time and to keep the starting features of the machine.At the beginning of the use you must do some
extra operations to allow to any machine parts to settle down in the final using conditions.
Please check frequently the working of the machine and do not force it to make too much cuts.
Keep the oil level of the tank of the hydraulic central station -dr.RI0085-by the dipstick -pos.7/dr.RI0085-.
The reducer connected to the electrical motor has not need any lubrication because it is lubricated with the
FOR-LIFE system . Please ckeck the tightness gaskets.
After a time of 80/100 working , use the machine in a normal way . The heating of the mechanical parts and
the oleodynamic parts is part of the usual working and anyhow does not exceed the foreseen thermic limits .
Please see the OIL AND LUBRICANTS TABLE to choose the most suitable one and to compare the
different types.
