PRECAUTION ON MAINTENANCE

Maintenance intervals
Determine the maintenance intervals in accordance with the time of the hour meter and certain
period of time.
This section shows the maintenance intervals on the assumption that the machine is used in
normal running conditions. Carry out maintenance earlier if the work environments are bad or
severe.
Preparation for maintenance
• Place the machine in a flat and rigid ground.
• For normal maintenance, lower the vessel completely.
To carry out maintenance with the vessel raised, raise the vessel fully and apply the safety
lever.
• Set the parking switch to the brake ON position and the left lever unit to the locked position,
stop the engine, and then remove the key from the engine key switch.
• Hang a tag indicating that inspection and maintenance are in progress at an easily visible
location on the engine key switch or the left lever unit.
Cautions for repair works requiring welding
• Turn off power. (Disconnect the cable from the negative terminal of the battery.)
• Do not put any seals, bearings or the like between the weld zone and GND.
• Do not connect the GND wire to the pin of the vessel or hydraulic cylinder. It is the best way
to connect the GND wire at or near the object to be welded.
Use genuine parts.
Be sure to use the genuine parts.
Use oil and grease of viscosity appropriate to the temperature.
Ask IHI's sales service dealer for important maintenance.
Ask IHI's sales service dealer for important maintenance works such as replacement of electronic
parts, adjustment of the hydraulic pressure and so forth that require professional knowledge and
technique.
