7.3       THE VACUUM TURNS BUT VACUUM IS INSUFFICIENT

·      The table cover ( tav. 18 - 19) is obstructed : replace

·      The vacuum fan ( tav. 31 - ref. 3) is dirty : clean.

 

7.4       THE TOP BUCK DOES NOT CLOSE

·      Disactivate the block on the top buck, by means of the button (tav. 07/B - ref. 5).

·      Lack of air in the machine at 6 bar pressure. Check on the pressure gauge (tav. 01 - ref. 13).

·      No air goes through the  closing valve positioned below the button (tav. 07 - ref. 1 and 2, 2 button version) or no air goes through the valve positioned above the pedal (tav. 07 - ref. 1, in version with lowering by pedal and safety guard) : replace the faulty part.

·      The AND component does not work (tav. 25¸29C - ref. 12): replace.

·      The closing timer if the machine is so equipped(tav. 30/30B - ref. 51) is faulty: replace.

 

7.5       THE  TOP BUCK DOES NOT OPEN

·      No air is discharged from the opening button: replace the faulty part  (tav. 07 - ref. 2/6).

·      The amplified valve positioned at the air inlet of the cylinder does not open  (tav. 25¸29C - ref. 8): replace.

 

 7.6      THE TOP BUCK OPENS SLOWLY  - REGULATION

·      The amplified valve positioned on the air inlet of the cylinder does not open (tav. 25¸29C - ref. 8): replace.

·      To adjust the closing speed of the top buck, the screw “A” of the shock absorber should be turned  (tav. 17A - ref. 7) in the clockwise direction to reduce and in the anti-clockwise direction to increase.

·      To regulate the speed of ascent of the top buck, the screw “B” of the shock sbsorber should be turned  (tav. 17A - ref. 7) in the clockwise direction to reduce and in the anti-clockwise direction to increase.

 

 

7.7       TOO MUCH WATER ENTERS THE BOILER

·      The level control (tav. 20 - ref. 7) is faulty : replace the entire component or the mercury bulb (tav. 20 - ref. 8).

·      The level control is not perfectly regulated: re-set by means of the regulation shaft.

·      The floater ball of the level control (tav. 20 - ref. 12) is damaged or weighed down by calcareous deposits: clean or replace.

·      Feed solenoid valve (tav. 20 - ref. 2) is faulty. Dismantle and check that there is no dirt in the small piston. Re-assemble the solenoid valve and control the coil: if it is burnt out, replace it. 

 

7.8       THE ELEMENTS ARE ACTIVATED BUT THE BOILER DOES NOT REACH                    PRESSURE LEVEL

·      The heating elements  (tav. 20 - ref. 19) are cut out and no power is getting through : replace.

·      The circuit elements is cutout: check the circuit and re-connect..

 

7.9       THE ELEMENTS ARE NOT ACTIVATED

·      The pressure switch (tav. 11 - ref. 8) is faulty : replace

·      The contactor coil (tav. 30/30C - ref. 13) is burnt out : replace.

·      The level control (tav. 20 - ref. 7) is faulty : replace the entire component or the mercury bulb which activates the element.

·      The electric circuit of the element is cutout: check the circuit and re-connect.

·      Fuse burnt out : replace

 

7.10     THE PRESSURE IN THE BOILER REACHES TOO HIGH OR TOO LOW VALUES

·      The pressure switch (tav. 20 - ref. 6) is not correctly regulated:  regulate correctly by screwing/unscrewing the regulation screw to increase/decrease pressure.

·      The pressure switch is faulty : replace.

 

7.11     THE SAFETY VALVE OPENS

·      Pressure switch (tav. 20 - ref. 6) set at too high values: lower the set pressure  see 7.9

·      Pressure switch is faulty: replace.

 

7.12     THE PUMP DOES NOT START     

·      The level control (tav. 20 - ref. 7) is faulty: replace the entire component or the mercury bulb  (tav. 20 - ref. 8) which activates the pump.

·      The electric circuit of the pump is cutout: check and re-connect.

·      The pump condenser (tav. 22 - ref. 7) is faulty: replace

·      The electric winding of the pump is cutout : if possible re-connect or re-wind .

·      The pump is blocked: unblock by using a screwdriver on the rear  of the motor  on the cooling fan.

·      Fuse burnt out: replace

 

7.13     THE PUMP TURNS BUT NO WATER GOES INTO THE BOILER

·      The  water solenoid valve (tav. 20 - ref. 2) or only the coil  (tav. 23 - ref. 3) is faulty : replace the damaged part.

·      There is air in the pump fan housing : partially unscrew the cap positioned near the water outlet pipe, let out all the air and screw up again.

·      The check valve (tav. 20 - ref. 3) is blocked: some light taps on the valve can re-establish functioning,  if this is not sufficient dismantle and clean.
