5. PERIODIC REPLACEMENT OF CRITICAL PARTS
5.1 PERIODIC REPLACEMENT INTERVAL (EVERY 2 YEARS)
In order to further increase the safety of the machine Morooka recommends periodic inspection and replacement of critical
parts (hydraulic hoses, fuel hoses, etc.) which are related to causes of fire and to efficiency in the raising and lowering of the
dump body and traveling and stopping functions of the machine.
With these parts, the material changes as time passes, and they easily wear or deteriorate. However, it is difficult to judge the
condition of the parts simply by periodic maintenance, so they should always be replaced after a fixed time has passed,
regardless of their condition. Always replace them with new genuine parts to ensure that the machine always maintains its
function completely.
5.2 PERIODIC INSPECTION
• Check the hydraulic hoses and fuel hoses carefully to check for cracks, deterioration, or other damage, and to
check that there is no leakage from the connections.
When carrying out checks before starting, always check the ground under the machine to check for traces of oil
leakage.
• When replacing the hydraulic hoses or fuel hoses, always order genuine parts. Never use any imitation or
substitute parts.
• When any hydraulic hose is replaced, always replace the O-rings at the same time. Failure to do this will cause oil
leakage.
If the monthly inspection or checks before starting show any abnormality, such as leakage of oil or deformation and cracking,
tighten the parts immediately or replace them with new genuine parts.
When doing this, check the hose clamps at the same time, and replace them if they are deformed or cracked.
Check and repair any hydraulic hoses, even if they are not listed as critical parts.
The table below shows the checks to be carried out during periodic maintenance.
