OPTIONAL ATTACHMENTS AND DEVICES
HYDRAULIC BREAKER, HYDRAULIC CRUSHER AND QUICK COUPLER
Always operate the crusher on a stable, level surface, not
on a slope or on crushed debris.
Do not use the crusher to haul or load crushed debris.
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.
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.
