If your problem is not among the ones listed in the following pages or you need the presence of qualified technicians,
please get in touch with the manufacturer or your local dealer, and always refer to this Manual.
21.1 - DEFECTS CAUSED BY THE MACHINE
Anomalies
Check
A* The blade electric motor does not work 3-4-5-9
B* The hydraulic circuit motor does not work 1-2-3-4-5-9-17
C* The electronic/electric panel does not turn on 6-7-8-9
D* Not enough pressure in the hydraulic circuit 10-11-12-13
E* The pump of the hydraulic unit is noisy 14-15-16-17
F* The coolant is not sufficient 18-19-20-21
G* The workpiece moves or deformes 22-23-24
H* The cutting cycle doesn’t start 23
LIST OF THE PARTS THAT MUST BE CHECKED
1 = Plug is correctly inserted in the socket
2 = Main switch
3 = The motor is burned or damaged
4 = Electric supply is not appropriate
5 = Transmission hindered between blade and blade arbor
6 = Fuses on the primary of the transformer
7 = Fuses on the secondary of the transformer
8 = Transformer damaged or burned
9 = Connection of the supply cables
10 = Oil level in the tank of the hydraulic unit
11 = Loss from pipes and/or connections
12 = The adjustments screw of the maximum pressure valve is loosened
13 = the maximum pressure valve is broken
14 = Quality of the hydraulic oil (old, too much liquid)
15 = There is water in the oil and/or there is some condensate in the tank
16 = Too high pressure (over 20 BAR)
17 = The hydraulic pump is blocked (seizure, expansion, oxidation)
18 = The circuit taps are closed
19 = The cooling filters are obstructed or must be cleaned
20 = The electro-pump does not work (see 3-4-5-9-24)
21 = The tank is empty or dirty
22 = Excessive cutting feed
23 = The vice is not closed enough (or is too closed), the piece is not properly clamped
24 = The control LUBRICANT OFF is active (pos. 22 / Drawing RI0055 for electronic models )
21.2 - DEFECTS OF THE BAND / CAUSES / SOLUTIONS
In case of broken teeth, broken blades or short blade life, lay down the broken band on the floor and check it carefully;
look for them in the following table and read the corresponding solution of the problem.
1. PREMATURE AND EXCESSIVE TEETH WEAR AND TEAR
- Insufficient pressure: increase it
- Reduce the blade speed
- Insufficient coolant flow
- Inappropriate cooling emulsion
- Incorrect blade pitch: use a blade with a thicker pitch
- Blade run-in not correctly carried out
- Blade turns in the wrong direction: reverse it
2. BLADE VIBRATION
- Increase or reduce the blade speed
- Dull vibration: increase the blade tension
- Teeth are too big for the piece that must be cut
- The vibration reverberates in the base; reduce the cutting pressure
- The vibration could be due to the high frequency: increase the sawframe down-feed speed
