1. PRECAUTIONS FOR MAINTENANCE 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 accidents or machine failures 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 agency to request repair. • In the event that a failure or malfunction is encountered in machine operation or found in inspection, report it to your employer or supervisor immediately. Contact us or our sales service agency 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 has reached the obligatory maintenance period. [2] USE GENUINE PARTS FOR REPLACEMENT Always use Maeda genuine parts as specified in the parts catalogue for part replacement. [3] USE PURE GREASE Always use Maeda pure grease. The viscosity of grease must conform to specifications according to ambient temperature. [4] USE CLEAN OIL AND GREASE Always use clean oil, grease, and container to keep impurities out of them. [5] KEEP THE MACHINE CLEAN Keep 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 finding their way into 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 comes to a stop. Replace drainage, drain oil, and filter only after they drop in temperature for safety. If the oil is cold, raise the temperature of the oil to approx. 20 to 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 a considerable amount of metal powder or foreign objects is present. [8] CAUTIONS FOR LUBRICATION 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 for the prevention of accidental engine starting. [11] FOLLOW SAFETY PRECAUTIONS Safety precautions provided on the machine should always be followed when using the machine.
