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 them or bend them sharply. If they are installed so, their service life will
be shortened extremely and they may be damaged.
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
Are 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 INSPECTION AND MAINTE-
NANCE WHEN ENGINE IS RUNNING (2-25)“ 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.
FUEL AND LUBRICANTS TO MATCH THE AMBIENT TEMPERATURE:
Select the fuel and lubricants to match the ambient temperature.
For details, see “RECOMMENDED FUEL, COOLANT, AND LUBRICANT (4-12)“.
