WARNING:
 When an attachment other than the standard bucket
is installed on the machine, the machine stability will
be different.
If a heavy attachment is used, not only will
controllability be affected but also machine stability
will be reduced, possibly causing safety hazard.
 Before installing attachments such as hydraulic
breaker, crusher (concrete crusher), or pulverizer,
take machine controllability into account when
selecting the weight of the attachment by referring
to the table below.
 According to the specifications of installed
attachment and the base machine, the machine
weight may exceed the allowable maximum
operating weight of the ROPS, making the ROPS
unable to assure the protective function for operator.
Refer to the ROPS certification affixed in the cab for
the allowable maximum operating weight.

 Breaker operation speed is faster than crusher operation
so that the recommended breaker max. weights are
reduced more than those of the crushers.
 Avoid installing an attachment with a long overall length.
Damage to the front attachment may result.
 When an attachment of the max. weight is installed,
always operate the attachment over the front or rear
side of the machine. In addition, avoid operating the
attachment at the maximum reach.
 Crushers are heavier than breakers. Slowly move the
control lever when operating a crusher.
