Thorough understanding of the inspection and maintenance items is required to perform efficient
inspection and maintenance that contributes to safe use of this machine.
• Do not perform any inspection or maintenance that is not described in this manual.
Potential serious accident or machine failure may occur if it is performed at the
discretion of the individual.
In the event that a judgment on the severity of a failure or malfunction is unable to be
made, contact us or our sales service agent to request repair.
• In the event that a failure or malfunction is encountered while the machine is in
operation or found during an inspection, report it to your employer or supervisor
immediately. Contact us or our sales service agent to request repair accordingly.
• Inspection and maintenance should be performed with the machine placed on a level
and strong footing.
[1] CHECK THE SERVICE METERS
Read the service meters daily to check for any maintenance item that reached the obligatory
maintenance period.
[2] USE GENUINE PARTS FOR REPLACEMENT
Always use Maeda genuine parts as specified in the parts catalog for part replacement.
[3] USE DESIGNATED GREASE
Use the designated grease. The viscosity of grease must conform to specifications according to
ambient temperature.
[4] USE CLEAN OIL AND GREASE
Always use clean oil or grease, and keep in a secure container to reduce contact with impurities.
[5] KEEP THE MACHINE CLEAN
Wash the machine clean to facilitate the detection of a malfunction. Especially keep the grease
nipple, breather, and oil level gauge (oil access door) clean to prevent impurities from entering
the machine.
[6] HANDLE WATER AND OIL AT ADEQUATE TEMPERATURE
Drainage, drain oil, and exhaust filter will be at elevated temperatures immediately after the
machine is stopped. Replace drainage, drain oil, and filter only after they drop in temperature for
safety.
On the contrary, if the oil is cold, raise the temperature of the oil (to approx. 20 – 40°C).
[7] CHECK DRAIN OIL AND OIL FILTER
For replacement of oil and filter, check the drain oil and exhaust filter to make sure no
considerable amount of metal powder or foreign objects is present.
[8] CAUTIONS IN DRIVING
Do not remove the strainer to lubricate if it is attached to the lubrication opening.
[9] PROTECT OIL FROM IMPURITIES
Avoid dust when inspecting and replacing the oil to keep impurities out of the oil.
[10] ATTACH A WARNING TAG
When draining coolant and oil, always attach a warning tag to the travelling operation unit to
prevent accidental engine ignition.
[11] FOLLOW SAFETY PRECAUTIONS
Safety precautions provided on the machine should always be followed when using the machine.
