After inspection and maintenance
If no checks have been made after inspection
and maintenance, unexpected failure may oc-
cur, causing severe injury or damage. The fol-
lowing items must be observed:
●
Checks when machine is running.
●
For more information on checks during
engine operation see "Maintenance dur-
ing Engine Running." Be alert to your
safety in the meantime.
●
Whether the checked or maintained
parts work normally.
●
Whether oil leakage occurs when the
engine speed increases and the oil is
under pressure.
●
Checks after the operation (when the en-
gine has been shut down)
●
Whether you have missed the items to
be checked or maintained.
●
Whether all the checks and mainte-
nance have been performed correctly.
●
Whether any tools and parts are left in
the machine. It is very dangerous to
have a foreign object blocked in the link-
age.
●
Whether leakage of water or oil occurs;
whether all the bolts have been screwed
tightly.
Closing engine hood properly
When the engine hood is closed after inspec-
tion and maintenance, hold the lever and lift
the engine hood slightly in order to check
whether the lock is securely engaged. An un-
locked hood may be opened and cause acci-
dents.
