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 coolant or oil leaks?
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 (2-29)“ 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.
