Every month replace the coolant and clean the tank; be sure that any screws and nuts that can be loosened
when using, are locked.
Insure that stroke end and switches are working and the conditions of the cables, tubes and hydraulic-
pneumatic connections are good.
Test all devices that are not usually very used.

REPLACEMENT OF BAND
Work in cutting position 0 deg., with the saw frame up and the current off.
Open the upper cover -pos.2/dr.RI0103- and the cover band protection guard-pos.3/dr.RI0103.
Take away the safety screws-pos.6/dr.RI0107- that allow to line up the both work table. Unscrew the screws-
pos.1 and 5/dr.RI0107 about 6 turns - to make the lower sawing side accessible.
Unlock the band cleaning brusch -pos.6/dr.RI0105- by moving it away from the band , then wheel it about 20
deg. in the clock wise to fix it in a convenient position.
Clean the chips from the band guide head -pos.1/dr.RI0103- and pos.7/dr.RI0105- and the area where the
durty and the chips can be piled up .
Unscrew completely the screw -pos.4/dr.RI0103- to take out the tension to the band and to make easy the
next operations. Take the band off , at first from the pulleys -pos.6/dr.RI0105- and then from the band
guides-pos.7/dr.RI0105-.
Keep that there is no durty or chips on the pulleys , and by considering the cutting direction -
pos.7/dr.RI0103, put the new band in the band guides then on the pulleys. Screw a little the screw-
pos.4/dr.RI0103- being sure that the band keeps its back in contact with the pulleys,its back is against the
upper band guide side -pos.1/dr.RI0103-, and it put in action the stroke end which detect the band ( it is
inside the upper band guide ).
Move the band cleaning brusch to the beginning position-pos.6/dr.RI0105-then close again the band
protection guard. Push the main switch and after the control device working is stabilized , push several times
the button MODE -pos.15/dr.RI0055- until the LED with the symbol "BAND " -pos.6/dr.RI0055 is lighting (
the LED flashes when the band is not tensioned enough or is out of its position ) .
Screw the band tensioner screw again-pos.4/dr.RI0103- until the LED continously lights .
Close the vice clompletely ( against the supporting jaws ), reduce the cutting speed at 0-pos.14/dr.RI0102-,
formulate the speed "1" ( by pushing the button -pos.11/dr.RI0055-), exclude the delivery of the cooling with
the button-pos.22/dr.RI00545 ans start the cutting cycle by reducing the band speed about 15m/min.
Increase a little the cutting speed with the button -pos.14/dr.RI0102- then keep that the band perfectly slides
on the pulleys and on the band guide heads ( to make easy the adjustment lubricate the band surface with
oil ) . Move the work table to the start position -pos.7/dr.RI0107-, screw the both fixing screws -pos.1 and 5
/dr.RI0107- without tighting them too much ( tightening couple about 0.2 Kgm ) then put " the safety screw "
in its seat-pos.6/dr.RI0107-.
