VHP hoses Issue date 19 November 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 November 19 2015 Printed November 19 2015 Page 2 of 9 O TRANSFER OIL thermoplastic and ptfe hoses fittings and assemblies A 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 transferoil com www transferoil com air conditioning amp industrial vat and business regi
