Section 5 – BREAKING-IN MACHINE Mini-Crawler Crane M A E D A
5-12 3/2019 MC305C-3
BREAKING-IN MACHINE
CAUTION: Perform breaking-in for the period
of about the first 250 hours (hours displayed
on the service meter).
The life of the machine shortens if overloaded
operation or task is performed before the
various sections of the machine are used to
the operation.
While this machine is shipped after thorough
adjustment and inspection, forcing the machine
from the beginning will quickly degrade the
functions of engine and crane, shortening their
life.
Perform the breaking-in for the first "250 hours"
(time displayed on the service meter).
Pay attentions particularly to the followings during
the breaking-in period.
• Be sure to perform the warm-up operation and
avoid idling away after the engine has started.
See "OPERATIONS AND CHECKS AFTER
STARTING ENGINE" on page 4-18.
• Avoid overloaded operation or tasks with
high-speed operation.
• Avoid sudden starting, sudden acceleration,
unnecessary sudden stop or sudden steering
• When the breaking-in period reaches "50 hours",
do not fail to change the engine oil. See
"Replace Engine Oil and Oil Filter" on page
5-41.
• The metal powder produced inside the engine
through breaking-in increases in the engine oil
and it deteriorates the oil, shortening the engine
life.
