After Finishing Work - Hitachi EX27U Operator's Manual

3. When operating the crusher up high with the boom
fully raised, be careful of falling objects.
4. 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.
5. Always operate the crusher on a stable, level surface,
not on a slope or on crushed scraps.
6. Do not use the crusher to haul or load crushed
scraps.
7. Frequent replacing of the bucket with the crusher or
breaker subjects the machine's hydraulic system to
possible contamination and accelerated deterioration.
Replace hydraulic filter elements and hydraulic oil
more often than when simply digging, to prevent
damage to hydraulic pumps and other hydraulic com-
ponents. Refer to "Operating the Hydraulic Breaker"
in this section for replacement intervals.
8. Always remove the crusher from the excavator before
transporting the machine. Do not fully extend the
bucket cylinder when transporting, as this may dam-
age the front attachment, when vibrations arise dur-
ing transportation.

AFTER FINISHING WORK

1. Find a safe, level place to park, with no danger of fal-
ling rocks or other debris. Be sure to lower the bucket
and blade to the ground.
2. Fill the tank with fuel.
3. Clean the machine thoroughly.
