GUIDE TO MAINTENANCE MAINTENANCE
4-4
PRECAUTIONS WHEN INSTALLING HYDRAULIC HOSES:
q 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.
q When installing the hoses, do not twist or bend them into loops with a small radius.
This will cause damage to the hose and drastically reduce its service life.
CHECKS AFTER INSPECTION AND MAINTENANCE WORK:
If you forget to perform the checks after inspection and maintenance, unexpected problems may occur, and this
may lead to serious injury or property damage. Always do the following:
q Checks after operation (with engine stopped)
q Have any inspection and maintenance points been forgotten?
q Have all inspection and maintenance items been performed correctly?
q 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.
q Is there any leakage of coolant or oil? Have all nuts and bolts been tightened?
q Checks when engine is running
q For the checks when the engine is running, see “TWO WORKERS FOR MAINTENANCE WHEN ENGINE
IS RUNNING (2-28)“ in the SAFETY section, and take care of safety sufficiently.
q Check that the inspected and maintained parts work normally.
q Raise the engine speed and check for fuel leakage and oil leakage.
