(FIG 2)

TRACTION : Do not use hose in tension

Let it form a small bow

(FIG 3)
(FIG4)

TORSION:  Hose  is not  manufactured  to  work in  torsion.

During installation it is essential to ensure that the hose is not twisted. Let it follow an ideal lay-line


(FIG 5)

(FIG 6)

BENDING  RADIUS: Installation  tighter  than the minimum  bending radius reduces the life of the hose considerably. Moreover it is  not  necessary  to avoid bending close to the end fitting.

(FIG 10)
Do not support hoses with ropes  or  chains    Flexible  hose-supports  or  polyester  slings  are recommended  

(FIG 11)

(FIG 12)

Although the hoses are manufactured to guarantee exceptional resistance to abrasion, it is advisable  to move them  with care, avoiding knocks, dragging over abrasive surfaces  or  crushing, hoses  must  not  be  pulled  violently when twisted or knotted.

Moreover a visual check must  be  carried  out to  make  sure  that  there are  no  obstructions,  cuts, damaged cover  or any  other  evident  imperfections 


INSTALLATION : The hoses must be supported to allow normal movement when under pressure (dimensional variations).


NORMS AND METHOD OF USE :  Prior to  installation  it is  necessary to check the  characteristics of  the hose  carefully  to ensure that type, diameter and length conform to the required specification.


MAINTENANCE : Even  when  choice,  storage  and  installation  is carried out correctly,  regular  maintenance  is   necessary.  Frequency  of  the  latter  is determined  by  use.  During regular checks, special attention must be paid to couplings  and  to appearance of irregularities which can indicate deterioration of the hose,  After use,  it  is  advisable  to empty  the  hoses carefully and if necessary, clean  thoroughly. We  recommend  in any case, that the hoses be checked and tested under pressure once a year,


STORAGE : Hose  must  be  stored  in a  relaxed  condition  free from tension, compression or other  deformation. Contact  with objects that could pierce or cut must be avoided.  when not in  use, hose should be stored in a dark place preferably,  avoiding  direct  sunlight  and  rain. It  must  be  protected  from rodents  and  insists, When  such  a  risk is probable, appropriate precautions must be taken.

NEVER  weld  reduction  couplings  or  flanges  onto  original  hose fittings,
NEVER close or hold the coupling ferrules in a bench vice as they could be deformed. If necessary, hold the hose itself, closing the vice onto the outside spirals of the hose.
