GENERAL / Tightening Connecting Hose RIGHT CAUTION: When replacing the hoses, use only genuine Hitachi service parts. Using hoses other than genuine Hitachi hoses may cause oil leaks, hose rupture or separation of fitting, possibly resulting in a fire on the machine. Do not install hoses kinked. Application of high oil pressure, vibration, or an impact to a kinked hose may result in oil leaks, hose rupture or separation of fitting. Utilize the print marks on hoses when installing in order to prevent hose from being kinked. Take necessary measures to protect hoses from rubbing against each other. If the hoses rub against each other, wear to the hoses may result and lead to hose rupture.
Take care so that the hoses do not come into contact with the moving parts or sharp objects. WRONG W105-01-01-011 RIGHT W105-01-01-012 WRONG RIGHT Clamp Clamp Rubbing Against Each Other W105-01-01-013 WRONG RIGHT Rubbing Against Each Other W105-01-01-014 Clamp W1-2-8 WRONG
