2.4 BREAKING-IN MACHINE
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 “Operation 2.3 Operations and Checks after Starting Engine”
• 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 “Maintenance 8.2 [1] Replacement Engine Lubricating oil and Oil filter cartridge”.
The metal powder produced inside the engine through breaking-in increases in the engine oil and it
deteriorates the oil, shortening the engine life.
2.5 MACHINE TRAVELING POSTURE
• When moving this machine self-propelled, take the “traveling posture” with which the boom,
hook block, and outriggers are stowed.
• Traveling or traveling hoist with the boom extended is essentially prohibited. This will overturn
the machine, causing serious injury accidents.
• Do not use this machine for other purpose than the major purpose such as using it for carrying
the load on the machine.
• Follow the local laws and regulations if driving the machine on public roads.
Take the traveling posture shown on the right when moving the
machine.
1. See “Operation 2.23 Crane Stowing Operation” to stow the
crane. Stow the hook block in the specified position.
2. See “Operation 2.24 Outrigger Stowing Operation” to stow the
outriggers.
3. Verify that the emergency stop cancel switch is at the OFF
(auto) position.
