GENERAL / Tightening Connecting Hose RIGHT WRONG 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 ob- jects. W105-01-01-011 RIGHT WRONG Rubbing Against Each Other W105-01-01-012 RIGHT WRONG Clamp Clamp Rubbing Against Each Other W105-01-01-013 RIGHT WRONG Rubbing Against Each Other Clamp W105-01-01-014 W1-2-8
