• 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 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.
