OPERATING THE MACHINE When operating the crusher up high with the boom fully raised, be careful of falling objects. WRONG M107-05-048 • When operating the crusher on a floor in a building, first confirm that the floor has sufficient strength to support the load caused by crushing, in addition to the machine weight. • Always operate the crusher on a stable, level surface, not on a slope or on crushed scraps. • Do not use the crusher to haul or load crushed scraps.
• If a multiple number of attachments, such as crusher and bucket, or crusher and breaker, are used, replacing them with each other at intervals, impurities are more apt to en- ter the hydraulic system and the hydraulic oil deteriorates quickly. For this reason, replace the hydraulic oil tank filter and change the hydraulic oil at the intervals specified in the breaker time sharing diagram in the previous section. Read the breaker time sharing diagram supposing that time sharing percentage of attachment (s) other than the crusher is that of the breaker. • Always remove the crusher from the excavator before transporting the machine.
Do not fully extend the bucket cylinder when transporting, as this may damage the front attachment, when vibrations arise during transportation. WRONG M107-05-049 5-27
