Hitachi ZAXIS 450LC-3 Operator's Manual page 188

• When operating the crusher up high with the boom fully
raised, be careful of falling objects.
• 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 enter 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.
