10 - ADJUSTMENTS FOR VTF 500 SHI-E /ESC ( make it with the machine disconnected ) .
10.1
Vice - dr.RI0107- The machine is equipped with 2 aluminium closing jaws-pos.8-, the thiner allows the jaw
to reach the maximum opening capacity (330 mm ), when the saw frame cants to 5 deg.from the vertical it
must be used the bigger one because it reduces a little the maximum opening ( 300 mm. )
To replace them, open the vice completely and unscrew the fixed screws. NEVER USE THE MACHINE
WITHOUT JAWS.
- The handle-pos.9- can be swiveled around its own axis when being in an inconvenient position or if the
sliding vice part slips backwards in consequence of the use ; make as follows : wheel the handle to lock the
vice , then by pulling it in the direction shown by the arrow -pos.10- ( by keeping the central screw immobile )
wheel it according to the need; by releasing the handle , it automatically locks in the new position.
10.2
Band - dr.RI0... - band guides adjustment to change the thickness of the band :
You should adjust the band guide sliding block when having a band with a different thickness of 1.10 mm or
if in consequence of the long use , the band is not good drived by the hard metal tip ( please ask to the the
Technical Service Staff ) .
For the adjustment, operate as follows.
Check that the playe is not excessive ( max. 0.02 or 0.03 mm ).
The mechanical fixing hard metal pads can be replaced one by one :
Separate the band guides in the half by unscrewing the fixing screws-pos............, take away the TORS
fixing screws-pos............- and assemble the new metal pads -pos........ ( AKPA 220408TR H2M type ). The
central square metal pad -pos...........( SNMA 190616 H2M TYPE ) can be used from the 4 sides before
being replaced. The roller guide bearings are already lubricated with lithium grease ; They are FAG KR19C
type.
10.3
General working pressure -dr.RI/0085- In the hydraulic version the pressure is made by a modular central
that incorporates the manometer-pos.1- ( if it is on, it shows about 20 BAR ), the vice valve-pos.3-, the
maximum valve-pos.5- and the duplex valve -pos.8-.
It is possible to install a proper valve to reduce the closing vice power in the case where the material can be
deformed.
10.4
Cutting speed -pos.15/ dr.RI0102- Wheel from 0 to the maximum indicated power to increase the speed of
the blade that penetrates the workpiece; to change it , it is necessary to consider the following :
the cutting material, the blade speed, form, sizes of the workpiece and its locking, the cooling blade
conditions and so on .

MAINTENANCE
Follow regularly the above mentioned operations to keep at best the technical features, the productive
features and the security one foreseen by the manufacturer.
Do it daily or more frequently if you make a demanding work.
Remove the metal chips of the machine particularly those near the upper and lower band guide head ( by
using the standard little cleaning gun ) .
Convey the most little in the chip tray that must be taken away and emptied ;
Restore the coolant level.
Check upon the blade conditions and replace it if necessary.
Control the band cleaning brusch, put back it again or replace it if necessary.
Be sure that the VULKOLAN band guides -pos.4 and 5/dr.RI0105- are in good conditions and keep clean the
pulley surface.
Clean the machine every week , lubricate any joint points and the sliding surfaces with oil or grease;
Be sure that there is some oil in the central tank station by checking with the proper dipstick-
pos.7/dr.RI0085-.
