OPERATION
5-25
•
When crushing objects in high positions such as a
ceiling, carefully operate the machine so that falling
objects do not come in contact with the machine.
•
Before operating the machine on a floor of structures,
check that the strength of the floor is enough to
support the machine weight. Depending on type of
work the machine is engaged in, crushing reaction
force may be added to the floor beside the machine
weight.
•
Start operation only after the machine is horizontally
parked and the footing is stabilized. Never operated
the machine positioned on stacks of rubble, or inclined
grounds.
•
Do not move or load crushed materials using the
crusher.
•
When replacing the crusher with other work tools such
as a bucket or breaker, the hydraulic oil may easily
become contaminated. Change the hydraulic oil and
replace the full flow filter element at the same intervals
as applied to the hydraulic breaker.
•
Before transporting the machine on a trailer, remove
the crusher from the front attachment. Position the
bucket cylinder so that the cylinder is not fully
extended during transportation. (During transportation,
the machine may be raised off the trailer deck floor
due to vibration as mentioned in Step 1, possibly
resulting in damage to the front attachment.
PRECAUTIONS FOR AFTER OPERATING THE
MACHINE
1. After operating the machine, move the machine to a
level solid ground where no possibility of falling
stones, landslide, or flooding is present. (Refer to the
Parking group in the Driving Machine section.)
2. Fully refill the fuel.
3. Clean the machine.
4. During cold weather season, remove the coolant from
the radiator and the water jacket. Attach “No Coolant”
tag in an easy-to-see place.
