1.5 Inspecting and adjusting low idle speed
and high idle speed
&$87,21
(a) The minimum no-load speed (low idle speed) and
the maximum no-load speed (high idle speed) of
each engine have been checked on test bench
and then their setting bolts have been sealed at
the factory. Only the service shops designated by
Mitsubishi are authorized to perform checking and
adjusting of these settings.
(b) Be sure to seal all the external stoppers in the
same manner as they were sealed at the factory if
adjustments have been made on the governor.
Whether the seals are intact or not has important
effect on the validity of claims under warranty. Be
sure to seal all of the specified locations.
(c) When inspecting and adjusting the governor, be
prepared to operate the engine stop lever manu-
ally in anticipation of engine overrunning.
Note: Prior to inspecting and adjusting the governor, be sure
to warm up the engine long enough to raise the
coolant and oil temperatures to 70°C [158°F] or
higher.
