Title Assembling instructions OSM hoses Issue date 20 May 2015 3 Assembling the insert Push the insert into the hose end Use of a lubricating oil should not normally be required and should not automatically be used If required also a rubber mallet can be used to gently tap the insert into the hose end However in the event lubrication is required this should be the smallest amount possible and applied by wet sponge to the end of the insert Incorrect lubricating as it is visible in the pictures below may cause problems at the fittings Do not fully immerse the insert tail in oil Oil dipping of the insert can result in lubrication fluid trapped into insert tail grooves which can be the cause of dangerous fitting blow offs when the hose assembly is pressurized None of our OSM hoses are intended to be used in applications with concentrations of oxygen above 26 however never use lubrication oil when assembling hoses that are intended to be used with concentrations of oxygen above 26 WRONG USE OF LUBRICATIN Transfer Oil S p A Last modify May 20 2015 Printed May 20 2015 Page 4 of 8 TRANSFER OIL thermoplastic and ptfe hoses fittings and assemblies Transfer Oil S p A via sacca 64 43052 Colorno Parma Italy hydraulic tel 39 0521 3139 fax 39 0521 814160 info transferoil com www transferoil com air conditioning amp industrial vat and business register of parma IT 02302. share capital EUR 2 500 000 fully paid up amp refrigeration Title Assembling instructions OSM hoses Issue date 20 May 2015 1 Preparing the assembly Cut the hose to the right length taking care of making a perfectly perpendicular cut Be certain that the equipment used is a suitable hose cutting machine fit for purpose Follow safety instructions supplied with the cutting machine Safety glasses should always be worn when cutting any hose with rotating blade cutters Cutting the hose The cut must be clean without excessively melting or crushing the hose Blades should be kept sharp at all times Remove burrs and or other residual from the cut surface externally and internally Make sure that no dust impurities or material residual from the cutting operation entered in the hose as solid particles can contaminate the fluid and damage the pump or other components in the high pressure circuit In addition assembly flushing can be performed depending on the degree of cleanliness required in your application and on your standard procedures Use a proper tool to remove burrs and or residual from the cut surface Transfer Oil S p A Last modify May 20 2015 Printed May 20 2015 Page 2 of 8 TRANSFER OIL thermoplastic and ptfe hoses fittings and assemblies Se Transfer Oil S p A via sacca 64 43052 Colorno Parma Italy G 0 M A X hydraulic tel 39 0521 3139 fax 39 0521 814160 info tra
