9. MAINTENANCE AND REPAIRS
9.1 GENERAL SAFETY MEASURES
A. Lockable main switch. Use the padlock in the event of machine failure or replacement of the band. The
padlock key should be entrusted to a responsible person.
B. Before carrying out any work on electrical equipment, remove the power supply plug from the control panel
(disconnect voltage).
C. Only use cables to supply power, which have a cross-section suited to the power of the machine.
D. Opening key. The keys of the machine should be kept by authorized personnel. Do not leave the keys for doors
which provide access to the hydraulic or electrical parts or keys to lockable switches in easy of reach of unauthorized
personnel.
E. Repairs should only be carried out by authorized personnel. Only spare parts made by the original manufacturer
should be used, otherwise these could cause damage or injury.
9.2 ROUTINE CHECKS AND MAINTENANCE
FREQUENCY
(working hours)
OPERATION
100 hours Adjustment blade guide bearings
1000 Lubrication of mobile parts in the piece locking vice
1500 Blade drive reduction unit
50 Cleaning of the coolant tank and filter check
if necessary Check functioning of bench lever
Monthly Check oil in the control unit
if necessary Add hydraulic unit oil with AGIP ARNICA 32
9.3 Description of routine maintenance
A.Adjustment of the blade guide bearings
Loosen the screw 27, rotate the cams 34, so that the blade guide bushings vertically position the blade in axis (DRAW.
3-4-5 ENCL. 3). Tighten the dowels 105 until the blade secured. Loosen the dowels 105 slightly (about 1/10 of a turn).
The front blade guides must be positioned the nearest possible to the piece to be cut. Check every 3 months the
existing tolerance between the blade guides, making sure that it does not exceed the blade thickness of one tenth of a
millimeter, so as to avoid inexactnesses in the cut squaring. Periodically check with mounted blade that the blade guide
bearings rotate freely.
B. Lubrication of mobile parts of piece locking vice
Clean and grease the mobile parts of the counter-vice 61 and vice 62. In case of sliding difficulties or play the clamp
guides carry out the following operations: loosen nut 88, adjust dowel 160 and secure nut 88 (Draw.8 Encl.3).
C. Blade drive reduction unit
First oil change after 500 working hours, other changes after 1500 hours (AGIP BLASIA 150).
D. Cleaning of the coolant tank.
To clean the coolant tank, simply remove the tank with the filter which is situated at the back of the machine. Empty the
coolant from the tank and collect the coolant in a container for future disposal. Clean away the shavings and the metallic
powder, taking care not to scatter this over the machine especially around the motor and the box containing the
electrical equipment. Fill the tank with the amount and liquid stated earlier.
E. Checking of bench lever functioning
Check regularly that the rotation release - locking lever is working properly. In the event of the lever not locking correctly,
loosen grub screw 103 (draw.8 Encl.3), tighten nut 64 and fasten grub screw 103 again. Make sure that with the bench
lever in position B, arm 58 which supports the bow, can rotate freely.
F. Check oil in the control unit
Check the level oil in the control unit tank and add the amount necessary.
9.4 POSSIBLE INCONVENIENCES
A. Automatic cycle does not function
-If this cycle does not function, make sure that all the limit switches are energized.
B. Oblique cutting
Check the inclination of the blade using the comparator located near the saw blade guide and use the hexagon socket
headless screwswhich regulate the saw blade guide, to reset the correct inclination.
C. Undulated - concave - convex cutting
-Make sure the blade is not worn.
-Adjust the blade rotation speed in relation to the material, using the speed selector (or the variator, if fitted).
-Adjust the bow down stroke speed in relation to the material, using the cutting feed regulator.
-Adjust the bow down stroke pressure in relation to the material, using the cutting pressure regulator.
-Check the exact alignment of the saw blade guide with the mobile guide in different positions (adjust the hexagon
socket headless screws).
