Precautions For Crusher Operation - Hitachi Zaxis 850LC-3 Operator's Manual

PRECAUTIONS FOR CRUSHER OPERATION

Prevent machine tipping over and damage to the front at-
tachment. Observe the following precautions for crusher
operation.
WARNING: Machine stability is reduced as crusher is
much heavier than bucket.
When operating with a crusher, the machine is more
apt to tip over. Also, falling or flying objects may hit
the cab or other part of the machine. Observe the fol-
lowing precautions and take any other precautions
necessary to prevent accidents and machine damage
from occurring.
• Do not allow the machine's weight to be supported by the
crusher or bucket cylinder with the bucket cylinder fully
extended or retracted. Doing so may damage the front
attachment. In particular, avoid doing so with the bucket
cylinder fully extended, as the front attachment will be
easily damaged.
Take care to prevent this from happening when disman-
tling foundation structures using the crusher.
• Do not attempt to perform crushing on either side of the
machine. Always perform crushing operations to the fore
or rear, parallel with the tracks. Otherwise, tipping over
may occur.
