4.1 Guides to maintenance Maintenance Precautions when installing hydraulic hoses: z When removing parts at locations where there are O-rings or gasket seals, clean the mounting surface, and replace with new parts. When doing this, be careful not to forget to assemble the O- rings and gaskets. z When installing the hoses, do not twist them or bend them into loops with a small radius. This will cause damage to the hose and markedly reduce its service life. Checks after inspection and maintenance: If you forget carrying out the checks after inspection and mainte- nance, unexpected problems may occur, and this may lead to serious injury or property damage. Always do as follows.
z Checks after operation (with engine stopped) Ѓ Have any inspection and maintenance points been for- gotten? Ѓ Have all inspection and maintenance items been carried out correctly? Ѓ Have any tools or parts been dropped inside the machine? It is particularly dangerous if parts are dropped inside the machine and get caught in the lever linkage mechanism. Ѓ Is there any leakage of water or oil? Have all the bolts been tightened? z Check when the engine is running Ѓ See "Two workers for maintenance when engine is run- ning (2-31)" in the section on safety for checking when the engine is running. Pay attention to safety.
Ѓ Check if the inspected and maintenance area is operat- ing normally Ѓ Increase the engine speed to check for fuel and oil leak- age. 4-4 WA150-5H – VEAM934100
